+ OpenSSL CHANGES
+ _______________
+
+ This is a high-level summary of the most important changes.
+ For a full list of changes, see the git commit log; for example,
+ https://github.com/openssl/openssl/commits/ and pick the appropriate
+ release branch.
+
+ Changes between 1.1.0g and 1.1.0h [27 Mar 2018]
+
+  *) Constructed ASN.1 types with a recursive definition could exceed the stack
+
+     Constructed ASN.1 types with a recursive definition (such as can be found
+     in PKCS7) could eventually exceed the stack given malicious input with
+     excessive recursion. This could result in a Denial Of Service attack. There
+     are no such structures used within SSL/TLS that come from untrusted sources
+     so this is considered safe.
+
+     This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz
+     project.
+     (CVE-2018-0739)
+     [Matt Caswell]
+
+  *) Incorrect CRYPTO_memcmp on HP-UX PA-RISC
+
+     Because of an implementation bug the PA-RISC CRYPTO_memcmp function is
+     effectively reduced to only comparing the least significant bit of each
+     byte. This allows an attacker to forge messages that would be considered as
+     authenticated in an amount of tries lower than that guaranteed by the
+     security claims of the scheme. The module can only be compiled by the
+     HP-UX assembler, so that only HP-UX PA-RISC targets are affected.
+
+     This issue was reported to OpenSSL on 2nd March 2018 by Peter Waltenberg
+     (IBM).
+     (CVE-2018-0733)
+     [Andy Polyakov]
+
+  *) Add a build target 'build_all_generated', to build all generated files
+     and only that.  This can be used to prepare everything that requires
+     things like perl for a system that lacks perl and then move everything
+     to that system and do the rest of the build there.
+     [Richard Levitte]
+
+  *) Backport SSL_OP_NO_RENGOTIATION
+
+     OpenSSL 1.0.2 and below had the ability to disable renegotiation using the
+     (undocumented) SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS flag. Due to the opacity
+     changes this is no longer possible in 1.1.0. Therefore the new
+     SSL_OP_NO_RENEGOTIATION option from 1.1.1-dev has been backported to
+     1.1.0 to provide equivalent functionality.
+
+     Note that if an application built against 1.1.0h headers (or above) is run
+     using an older version of 1.1.0 (prior to 1.1.0h) then the option will be
+     accepted but nothing will happen, i.e. renegotiation will not be prevented.
+     [Matt Caswell]
+
+  *) Removed the OS390-Unix config target.  It relied on a script that doesn't
+     exist.
+     [Rich Salz]
+
+  *) rsaz_1024_mul_avx2 overflow bug on x86_64
+
+     There is an overflow bug in the AVX2 Montgomery multiplication procedure
+     used in exponentiation with 1024-bit moduli. No EC algorithms are affected.
+     Analysis suggests that attacks against RSA and DSA as a result of this
+     defect would be very difficult to perform and are not believed likely.
+     Attacks against DH1024 are considered just feasible, because most of the
+     work necessary to deduce information about a private key may be performed
+     offline. The amount of resources required for such an attack would be
+     significant. However, for an attack on TLS to be meaningful, the server
+     would have to share the DH1024 private key among multiple clients, which is
+     no longer an option since CVE-2016-0701.
+
+     This only affects processors that support the AVX2 but not ADX extensions
+     like Intel Haswell (4th generation).
+
+     This issue was reported to OpenSSL by David Benjamin (Google). The issue
+     was originally found via the OSS-Fuzz project.
+     (CVE-2017-3738)
+     [Andy Polyakov]
+
+ Changes between 1.1.0f and 1.1.0g [2 Nov 2017]
+
+  *) bn_sqrx8x_internal carry bug on x86_64
+
+     There is a carry propagating bug in the x86_64 Montgomery squaring
+     procedure. No EC algorithms are affected. Analysis suggests that attacks
+     against RSA and DSA as a result of this defect would be very difficult to
+     perform and are not believed likely. Attacks against DH are considered just
+     feasible (although very difficult) because most of the work necessary to
+     deduce information about a private key may be performed offline. The amount
+     of resources required for such an attack would be very significant and
+     likely only accessible to a limited number of attackers. An attacker would
+     additionally need online access to an unpatched system using the target
+     private key in a scenario with persistent DH parameters and a private
+     key that is shared between multiple clients.
+
+     This only affects processors that support the BMI1, BMI2 and ADX extensions
+     like Intel Broadwell (5th generation) and later or AMD Ryzen.
+
+     This issue was reported to OpenSSL by the OSS-Fuzz project.
+     (CVE-2017-3736)
+     [Andy Polyakov]
+
+  *) Malformed X.509 IPAddressFamily could cause OOB read
+
+     If an X.509 certificate has a malformed IPAddressFamily extension,
+     OpenSSL could do a one-byte buffer overread. The most likely result
+     would be an erroneous display of the certificate in text format.
+
+     This issue was reported to OpenSSL by the OSS-Fuzz project.
+     (CVE-2017-3735)
+     [Rich Salz]
+
+  *) Ignore the '-named_curve auto' value for compatibility of applications
+     with OpenSSL 1.0.2.
+     [Tomas Mraz <tmraz@fedoraproject.org>]
+
+  *) Support for SSL_OP_NO_ENCRYPT_THEN_MAC in SSL_CONF_cmd.
+     [Emilia Käsper]
+
+ Changes between 1.1.0e and 1.1.0f [25 May 2017]
+
+  *) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target
+     platform rather than 'mingw'.
+     [Richard Levitte]
+
+  *) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c.
+     VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1,
+     which is the minimum version we support.
+     [Richard Levitte]
+
+ Changes between 1.1.0d and 1.1.0e [16 Feb 2017]
+
+  *) Encrypt-Then-Mac renegotiation crash
+
+     During a renegotiation handshake if the Encrypt-Then-Mac extension is
+     negotiated where it was not in the original handshake (or vice-versa) then
+     this can cause OpenSSL to crash (dependant on ciphersuite). Both clients
+     and servers are affected.
+
+     This issue was reported to OpenSSL by Joe Orton (Red Hat).
+     (CVE-2017-3733)
+     [Matt Caswell]
+
+ Changes between 1.1.0c and 1.1.0d [26 Jan 2017]
+
+  *) Truncated packet could crash via OOB read
+
+     If one side of an SSL/TLS path is running on a 32-bit host and a specific
+     cipher is being used, then a truncated packet can cause that host to
+     perform an out-of-bounds read, usually resulting in a crash.
+
+     This issue was reported to OpenSSL by Robert Święcki of Google.
+     (CVE-2017-3731)
+     [Andy Polyakov]
+
+  *) Bad (EC)DHE parameters cause a client crash
+
+     If a malicious server supplies bad parameters for a DHE or ECDHE key
+     exchange then this can result in the client attempting to dereference a
+     NULL pointer leading to a client crash. This could be exploited in a Denial
+     of Service attack.
+
+     This issue was reported to OpenSSL by Guido Vranken.
+     (CVE-2017-3730)
+     [Matt Caswell]
+
+  *) BN_mod_exp may produce incorrect results on x86_64
+
+     There is a carry propagating bug in the x86_64 Montgomery squaring
+     procedure. No EC algorithms are affected. Analysis suggests that attacks
+     against RSA and DSA as a result of this defect would be very difficult to
+     perform and are not believed likely. Attacks against DH are considered just
+     feasible (although very difficult) because most of the work necessary to
+     deduce information about a private key may be performed offline. The amount
+     of resources required for such an attack would be very significant and
+     likely only accessible to a limited number of attackers. An attacker would
+     additionally need online access to an unpatched system using the target
+     private key in a scenario with persistent DH parameters and a private
+     key that is shared between multiple clients. For example this can occur by
+     default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very
+     similar to CVE-2015-3193 but must be treated as a separate problem.
+
+     This issue was reported to OpenSSL by the OSS-Fuzz project.
+     (CVE-2017-3732)
+     [Andy Polyakov]
+
+ Changes between 1.1.0b and 1.1.0c [10 Nov 2016]
+
+  *) ChaCha20/Poly1305 heap-buffer-overflow
+
+     TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to
+     a DoS attack by corrupting larger payloads. This can result in an OpenSSL
+     crash. This issue is not considered to be exploitable beyond a DoS.
+
+     This issue was reported to OpenSSL by Robert Święcki (Google Security Team)
+     (CVE-2016-7054)
+     [Richard Levitte]
+
+  *) CMS Null dereference
+
+     Applications parsing invalid CMS structures can crash with a NULL pointer
+     dereference. This is caused by a bug in the handling of the ASN.1 CHOICE
+     type in OpenSSL 1.1.0 which can result in a NULL value being passed to the
+     structure callback if an attempt is made to free certain invalid encodings.
+     Only CHOICE structures using a callback which do not handle NULL value are
+     affected.
+
+     This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure.
+     (CVE-2016-7053)
+     [Stephen Henson]
+
+  *) Montgomery multiplication may produce incorrect results
+
+     There is a carry propagating bug in the Broadwell-specific Montgomery
+     multiplication procedure that handles input lengths divisible by, but
+     longer than 256 bits. Analysis suggests that attacks against RSA, DSA
+     and DH private keys are impossible. This is because the subroutine in
+     question is not used in operations with the private key itself and an input
+     of the attacker's direct choice. Otherwise the bug can manifest itself as
+     transient authentication and key negotiation failures or reproducible
+     erroneous outcome of public-key operations with specially crafted input.
+     Among EC algorithms only Brainpool P-512 curves are affected and one
+     presumably can attack ECDH key negotiation. Impact was not analyzed in
+     detail, because pre-requisites for attack are considered unlikely. Namely
+     multiple clients have to choose the curve in question and the server has to
+     share the private key among them, neither of which is default behaviour.
+     Even then only clients that chose the curve will be affected.
+
+     This issue was publicly reported as transient failures and was not
+     initially recognized as a security issue. Thanks to Richard Morgan for
+     providing reproducible case.
+     (CVE-2016-7055)
+     [Andy Polyakov]
+
+  *) OpenSSL now fails if it receives an unrecognised record type in TLS1.0
+     or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to
+     prevent issues where no progress is being made and the peer continually
+     sends unrecognised record types, using up resources processing them.
+     [Matt Caswell]
+
+  *) Removed automatic addition of RPATH in shared libraries and executables,
+     as this was a remainder from OpenSSL 1.0.x and isn't needed any more.
+     [Richard Levitte]
+
+ Changes between 1.1.0a and 1.1.0b [26 Sep 2016]
+
+  *) Fix Use After Free for large message sizes
+
+     The patch applied to address CVE-2016-6307 resulted in an issue where if a
+     message larger than approx 16k is received then the underlying buffer to
+     store the incoming message is reallocated and moved. Unfortunately a
+     dangling pointer to the old location is left which results in an attempt to
+     write to the previously freed location. This is likely to result in a
+     crash, however it could potentially lead to execution of arbitrary code.
+
+     This issue only affects OpenSSL 1.1.0a.
+
+     This issue was reported to OpenSSL by Robert Święcki.
+     (CVE-2016-6309)
+     [Matt Caswell]
+
+ Changes between 1.1.0 and 1.1.0a [22 Sep 2016]
+
+  *) OCSP Status Request extension unbounded memory growth
+
+     A malicious client can send an excessively large OCSP Status Request
+     extension. If that client continually requests renegotiation, sending a
+     large OCSP Status Request extension each time, then there will be unbounded
+     memory growth on the server. This will eventually lead to a Denial Of
+     Service attack through memory exhaustion. Servers with a default
+     configuration are vulnerable even if they do not support OCSP. Builds using
+     the "no-ocsp" build time option are not affected.
+
+     This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.)
+     (CVE-2016-6304)
+     [Matt Caswell]
+
+  *) SSL_peek() hang on empty record
+
+     OpenSSL 1.1.0 SSL/TLS will hang during a call to SSL_peek() if the peer
+     sends an empty record. This could be exploited by a malicious peer in a
+     Denial Of Service attack.
+
+     This issue was reported to OpenSSL by Alex Gaynor.
+     (CVE-2016-6305)
+     [Matt Caswell]
+
+  *) Excessive allocation of memory in tls_get_message_header() and
+     dtls1_preprocess_fragment()
+
+     A (D)TLS message includes 3 bytes for its length in the header for the
+     message. This would allow for messages up to 16Mb in length. Messages of
+     this length are excessive and OpenSSL includes a check to ensure that a
+     peer is sending reasonably sized messages in order to avoid too much memory
+     being consumed to service a connection. A flaw in the logic of version
+     1.1.0 means that memory for the message is allocated too early, prior to
+     the excessive message length check. Due to way memory is allocated in
+     OpenSSL this could mean an attacker could force up to 21Mb to be allocated
+     to service a connection. This could lead to a Denial of Service through
+     memory exhaustion. However, the excessive message length check still takes
+     place, and this would cause the connection to immediately fail. Assuming
+     that the application calls SSL_free() on the failed connection in a timely
+     manner then the 21Mb of allocated memory will then be immediately freed
+     again. Therefore the excessive memory allocation will be transitory in
+     nature. This then means that there is only a security impact if:
+
+     1) The application does not call SSL_free() in a timely manner in the event
+     that the connection fails
+     or
+     2) The application is working in a constrained environment where there is
+     very little free memory
+     or
+     3) The attacker initiates multiple connection attempts such that there are
+     multiple connections in a state where memory has been allocated for the
+     connection; SSL_free() has not yet been called; and there is insufficient
+     memory to service the multiple requests.
+
+     Except in the instance of (1) above any Denial Of Service is likely to be
+     transitory because as soon as the connection fails the memory is
+     subsequently freed again in the SSL_free() call. However there is an
+     increased risk during this period of application crashes due to the lack of
+     memory - which would then mean a more serious Denial of Service.
+
+     This issue was reported to OpenSSL by Shi Lei (Gear Team, Qihoo 360 Inc.)
+     (CVE-2016-6307 and CVE-2016-6308)
+     [Matt Caswell]
+
+  *) solaris-x86-cc, i.e. 32-bit configuration with vendor compiler,
+     had to be removed. Primary reason is that vendor assembler can't
+     assemble our modules with -KPIC flag. As result it, assembly
+     support, was not even available as option. But its lack means
+     lack of side-channel resistant code, which is incompatible with
+     security by todays standards. Fortunately gcc is readily available
+     prepackaged option, which we firmly point at...
+     [Andy Polyakov]
+
+ Changes between 1.0.2h and 1.1.0  [25 Aug 2016]
+
+  *) Windows command-line tool supports UTF-8 opt-in option for arguments
+     and console input. Setting OPENSSL_WIN32_UTF8 environment variable
+     (to any value) allows Windows user to access PKCS#12 file generated
+     with Windows CryptoAPI and protected with non-ASCII password, as well
+     as files generated under UTF-8 locale on Linux also protected with
+     non-ASCII password.
+     [Andy Polyakov]
+
+  *) To mitigate the SWEET32 attack (CVE-2016-2183), 3DES cipher suites
+     have been disabled by default and removed from DEFAULT, just like RC4.
+     See the RC4 item below to re-enable both.
+     [Rich Salz]
+
+  *) The method for finding the storage location for the Windows RAND seed file
+     has changed. First we check %RANDFILE%. If that is not set then we check
+     the directories %HOME%, %USERPROFILE% and %SYSTEMROOT% in that order. If
+     all else fails we fall back to C:\.
+     [Matt Caswell]
+
+  *) The EVP_EncryptUpdate() function has had its return type changed from void
+     to int. A return of 0 indicates and error while a return of 1 indicates
+     success.
+     [Matt Caswell]
+
+  *) The flags RSA_FLAG_NO_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME and
+     DH_FLAG_NO_EXP_CONSTTIME which previously provided the ability to switch
+     off the constant time implementation for RSA, DSA and DH have been made
+     no-ops and deprecated.
+     [Matt Caswell]
+
+  *) Windows RAND implementation was simplified to only get entropy by
+     calling CryptGenRandom(). Various other RAND-related tickets
+     were also closed.
+     [Joseph Wylie Yandle, Rich Salz]
+
+  *) The stack and lhash API's were renamed to start with OPENSSL_SK_
+     and OPENSSL_LH_, respectively.  The old names are available
+     with API compatibility.  They new names are now completely documented.
+     [Rich Salz]
+
+  *) Unify TYPE_up_ref(obj) methods signature.
+     SSL_CTX_up_ref(), SSL_up_ref(), X509_up_ref(), EVP_PKEY_up_ref(),
+     X509_CRL_up_ref(), X509_OBJECT_up_ref_count() methods are now returning an
+     int (instead of void) like all others TYPE_up_ref() methods.
+     So now these methods also check the return value of CRYPTO_atomic_add(),
+     and the validity of object reference counter.
+     [fdasilvayy@gmail.com]
+
+  *) With Windows Visual Studio builds, the .pdb files are installed
+     alongside the installed libraries and executables.  For a static
+     library installation, ossl_static.pdb is the associate compiler
+     generated .pdb file to be used when linking programs.
+     [Richard Levitte]
+
+  *) Remove openssl.spec.  Packaging files belong with the packagers.
+     [Richard Levitte]
+
+  *) Automatic Darwin/OSX configuration has had a refresh, it will now
+     recognise x86_64 architectures automatically.  You can still decide
+     to build for a different bitness with the environment variable
+     KERNEL_BITS (can be 32 or 64), for example:
+
+         KERNEL_BITS=32 ./config
+
+     [Richard Levitte]
+
+  *) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0,
+     256 bit AES and HMAC with SHA256.
+     [Steve Henson]
+
+  *) Remove support for MIPS o32 ABI on IRIX (and IRIX only).
+     [Andy Polyakov]
+
+  *) Triple-DES ciphers have been moved from HIGH to MEDIUM.
+     [Rich Salz]
+
+  *) To enable users to have their own config files and build file templates,
+     Configure looks in the directory indicated by the environment variable
+     OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/
+     directory.  On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical
+     name and is used as is.
+     [Richard Levitte]
+
+  *) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX,
+     X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD.  The unused type
+     X509_CERT_FILE_CTX was removed.
+     [Rich Salz]
+
+  *) "shared" builds are now the default. To create only static libraries use
+     the "no-shared" Configure option.
+     [Matt Caswell]
+
+  *) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
+     All of these option have not worked for some while and are fundamental
+     algorithms.
+     [Matt Caswell]
+
+  *) Make various cleanup routines no-ops and mark them as deprecated. Most
+     global cleanup functions are no longer required because they are handled
+     via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
+     Explicitly de-initing can cause problems (e.g. where a library that uses
+     OpenSSL de-inits, but an application is still using it). The affected
+     functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),
+     EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),
+     RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and
+     COMP_zlib_cleanup().
+     [Matt Caswell]
+
+  *) --strict-warnings no longer enables runtime debugging options
+     such as REF_DEBUG. Instead, debug options are automatically
+     enabled with '--debug' builds.
+     [Andy Polyakov, Emilia Käsper]
+
+  *) Made DH and DH_METHOD opaque. The structures for managing DH objects
+     have been moved out of the public header files. New functions for managing
+     these have been added.
+     [Matt Caswell]
+
+  *) Made RSA and RSA_METHOD opaque. The structures for managing RSA
+     objects have been moved out of the public header files. New
+     functions for managing these have been added.
+     [Richard Levitte]
+
+  *) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects
+     have been moved out of the public header files. New functions for managing
+     these have been added.
+     [Matt Caswell]
+
+  *) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been
+     moved out of the public header files. New functions for managing these
+     have been added.
+     [Matt Caswell]
+
+  *) Removed no-rijndael as a config option. Rijndael is an old name for AES.
+     [Matt Caswell]
+
+  *) Removed the mk1mf build scripts.
+     [Richard Levitte]
+
+  *) Headers are now wrapped, if necessary, with OPENSSL_NO_xxx, so
+     it is always safe to #include a header now.
+     [Rich Salz]
+
+  *) Removed the aged BC-32 config and all its supporting scripts
+     [Richard Levitte]
+
+  *) Removed support for Ultrix, Netware, and OS/2.
+     [Rich Salz]
+
+  *) Add support for HKDF.
+     [Alessandro Ghedini]
+
+  *) Add support for blake2b and blake2s
+     [Bill Cox]
+
+  *) Added support for "pipelining". Ciphers that have the
+     EVP_CIPH_FLAG_PIPELINE flag set have a capability to process multiple
+     encryptions/decryptions simultaneously. There are currently no built-in
+     ciphers with this property but the expectation is that engines will be able
+     to offer it to significantly improve throughput. Support has been extended
+     into libssl so that multiple records for a single connection can be
+     processed in one go (for >=TLS 1.1).
+     [Matt Caswell]
+
+  *) Added the AFALG engine. This is an async capable engine which is able to
+     offload work to the Linux kernel. In this initial version it only supports
+     AES128-CBC. The kernel must be version 4.1.0 or greater.
+     [Catriona Lucey]
+
+  *) OpenSSL now uses a new threading API. It is no longer necessary to
+     set locking callbacks to use OpenSSL in a multi-threaded environment. There
+     are two supported threading models: pthreads and windows threads. It is
+     also possible to configure OpenSSL at compile time for "no-threads". The
+     old threading API should no longer be used. The functions have been
+     replaced with "no-op" compatibility macros.
+     [Alessandro Ghedini, Matt Caswell]
+
+  *) Modify behavior of ALPN to invoke callback after SNI/servername
+     callback, such that updates to the SSL_CTX affect ALPN.
+     [Todd Short]
+
+  *) Add SSL_CIPHER queries for authentication and key-exchange.
+     [Todd Short]
+
+  *) Changes to the DEFAULT cipherlist:
+       - Prefer (EC)DHE handshakes over plain RSA.
+       - Prefer AEAD ciphers over legacy ciphers.
+       - Prefer ECDSA over RSA when both certificates are available.
+       - Prefer TLSv1.2 ciphers/PRF.
+       - Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the
+         default cipherlist.
+     [Emilia Käsper]
+
+  *) Change the ECC default curve list to be this, in order: x25519,
+     secp256r1, secp521r1, secp384r1.
+     [Rich Salz]
+
+  *) RC4 based libssl ciphersuites are now classed as "weak" ciphers and are
+     disabled by default. They can be re-enabled using the
+     enable-weak-ssl-ciphers option to Configure.
+     [Matt Caswell]
+
+  *) If the server has ALPN configured, but supports no protocols that the
+     client advertises, send a fatal "no_application_protocol" alert.
+     This behaviour is SHALL in RFC 7301, though it isn't universally
+     implemented by other servers.
+     [Emilia Käsper]
+
+  *) Add X25519 support.
+     Add ASN.1 and EVP_PKEY methods for X25519. This includes support
+     for public and private key encoding using the format documented in
+     draft-ietf-curdle-pkix-02. The corresponding EVP_PKEY method supports
+     key generation and key derivation.
+
+     TLS support complies with draft-ietf-tls-rfc4492bis-08 and uses
+     X25519(29).
+     [Steve Henson]
+
+  *) Deprecate SRP_VBASE_get_by_user.
+     SRP_VBASE_get_by_user had inconsistent memory management behaviour.
+     In order to fix an unavoidable memory leak (CVE-2016-0798),
+     SRP_VBASE_get_by_user was changed to ignore the "fake user" SRP
+     seed, even if the seed is configured.
+
+     Users should use SRP_VBASE_get1_by_user instead. Note that in
+     SRP_VBASE_get1_by_user, caller must free the returned value. Note
+     also that even though configuring the SRP seed attempts to hide
+     invalid usernames by continuing the handshake with fake
+     credentials, this behaviour is not constant time and no strong
+     guarantees are made that the handshake is indistinguishable from
+     that of a valid user.
+     [Emilia Käsper]
+
+  *) Configuration change; it's now possible to build dynamic engines
+     without having to build shared libraries and vice versa.  This
+     only applies to the engines in engines/, those in crypto/engine/
+     will always be built into libcrypto (i.e. "static").
+
+     Building dynamic engines is enabled by default; to disable, use
+     the configuration option "disable-dynamic-engine".
+
+     The only requirements for building dynamic engines are the
+     presence of the DSO module and building with position independent
+     code, so they will also automatically be disabled if configuring
+     with "disable-dso" or "disable-pic".
+
+     The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE
+     are also taken away from openssl/opensslconf.h, as they are
+     irrelevant.
+     [Richard Levitte]
+
+  *) Configuration change; if there is a known flag to compile
+     position independent code, it will always be applied on the
+     libcrypto and libssl object files, and never on the application
+     object files.  This means other libraries that use routines from
+     libcrypto / libssl can be made into shared libraries regardless
+     of how OpenSSL was configured.
+
+     If this isn't desirable, the configuration options "disable-pic"
+     or "no-pic" can be used to disable the use of PIC.  This will
+     also disable building shared libraries and dynamic engines.
+     [Richard Levitte]
+
+  *) Removed JPAKE code.  It was experimental and has no wide use.
+     [Rich Salz]
+
+  *) The INSTALL_PREFIX Makefile variable has been renamed to
+     DESTDIR.  That makes for less confusion on what this variable
+     is for.  Also, the configuration option --install_prefix is
+     removed.
+     [Richard Levitte]
+
+  *) Heartbeat for TLS has been removed and is disabled by default
+     for DTLS; configure with enable-heartbeats.  Code that uses the
+     old #define's might need to be updated.
+     [Emilia Käsper, Rich Salz]
+
+  *) Rename REF_CHECK to REF_DEBUG.
+     [Rich Salz]
+
+  *) New "unified" build system
+
+     The "unified" build system is aimed to be a common system for all
+     platforms we support.  With it comes new support for VMS.
+
+     This system builds supports building in a different directory tree
+     than the source tree.  It produces one Makefile (for unix family
+     or lookalikes), or one descrip.mms (for VMS).
+
+     The source of information to make the Makefile / descrip.mms is
+     small files called 'build.info', holding the necessary
+     information for each directory with source to compile, and a
+     template in Configurations, like unix-Makefile.tmpl or
+     descrip.mms.tmpl.
+
+     With this change, the library names were also renamed on Windows
+     and on VMS.  They now have names that are closer to the standard
+     on Unix, and include the major version number, and in certain
+     cases, the architecture they are built for.  See "Notes on shared
+     libraries" in INSTALL.
+
+     We rely heavily on the perl module Text::Template.
+     [Richard Levitte]
+
+  *) Added support for auto-initialisation and de-initialisation of the library.
+     OpenSSL no longer requires explicit init or deinit routines to be called,
+     except in certain circumstances. See the OPENSSL_init_crypto() and
+     OPENSSL_init_ssl() man pages for further information.
+     [Matt Caswell]
+
+  *) The arguments to the DTLSv1_listen function have changed. Specifically the
+     "peer" argument is now expected to be a BIO_ADDR object.
+
+  *) Rewrite of BIO networking library. The BIO library lacked consistent
+     support of IPv6, and adding it required some more extensive
+     modifications.  This introduces the BIO_ADDR and BIO_ADDRINFO types,
+     which hold all types of addresses and chains of address information.
+     It also introduces a new API, with functions like BIO_socket,
+     BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept.
+     The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram
+     have been adapted accordingly.
+     [Richard Levitte]
+
+  *) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without
+     the leading 0-byte.
+     [Emilia Käsper]
+
+  *) CRIME protection: disable compression by default, even if OpenSSL is
+     compiled with zlib enabled. Applications can still enable compression
+     by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by
+     using the SSL_CONF library to configure compression.
+     [Emilia Käsper]
+
+  *) The signature of the session callback configured with
+     SSL_CTX_sess_set_get_cb was changed. The read-only input buffer
+     was explicitly marked as 'const unsigned char*' instead of
+     'unsigned char*'.
+     [Emilia Käsper]
+
+  *) Always DPURIFY. Remove the use of uninitialized memory in the
+     RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op.
+     [Emilia Käsper]
+
+  *) Removed many obsolete configuration items, including
+        DES_PTR, DES_RISC1, DES_RISC2, DES_INT
+        MD2_CHAR, MD2_INT, MD2_LONG
+        BF_PTR, BF_PTR2
+        IDEA_SHORT, IDEA_LONG
+        RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX
+     [Rich Salz, with advice from Andy Polyakov]
+
+  *) Many BN internals have been moved to an internal header file.
+     [Rich Salz with help from Andy Polyakov]
+
+  *) Configuration and writing out the results from it has changed.
+     Files such as Makefile include/openssl/opensslconf.h and are now
+     produced through general templates, such as Makefile.in and
+     crypto/opensslconf.h.in and some help from the perl module
+     Text::Template.
+
+     Also, the center of configuration information is no longer
+     Makefile.  Instead, Configure produces a perl module in
+     configdata.pm which holds most of the config data (in the hash
+     table %config), the target data that comes from the target
+     configuration in one of the Configurations/*.conf files (in
+     %target).
+     [Richard Levitte]
+
+  *) To clarify their intended purposes, the Configure options
+     --prefix and --openssldir change their semantics, and become more
+     straightforward and less interdependent.
+
+     --prefix shall be used exclusively to give the location INSTALLTOP
+     where programs, scripts, libraries, include files and manuals are
+     going to be installed.  The default is now /usr/local.
+
+     --openssldir shall be used exclusively to give the default
+     location OPENSSLDIR where certificates, private keys, CRLs are
+     managed.  This is also where the default openssl.cnf gets
+     installed.
+     If the directory given with this option is a relative path, the
+     values of both the --prefix value and the --openssldir value will
+     be combined to become OPENSSLDIR.
+     The default for --openssldir is INSTALLTOP/ssl.
+
+     Anyone who uses --openssldir to specify where OpenSSL is to be
+     installed MUST change to use --prefix instead.
+     [Richard Levitte]
+
+  *) The GOST engine was out of date and therefore it has been removed. An up
+     to date GOST engine is now being maintained in an external repository.
+     See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains
+     support for GOST ciphersuites (these are only activated if a GOST engine
+     is present).
+     [Matt Caswell]
+
+  *) EGD is no longer supported by default; use enable-egd when
+     configuring.
+     [Ben Kaduk and Rich Salz]
+
+  *) The distribution now has Makefile.in files, which are used to
+     create Makefile's when Configure is run.  *Configure must be run
+     before trying to build now.*
+     [Rich Salz]
+
+  *) The return value for SSL_CIPHER_description() for error conditions
+     has changed.
+     [Rich Salz]
+
+  *) Support for RFC6698/RFC7671 DANE TLSA peer authentication.
+
+     Obtaining and performing DNSSEC validation of TLSA records is
+     the application's responsibility.  The application provides
+     the TLSA records of its choice to OpenSSL, and these are then
+     used to authenticate the peer.
+
+     The TLSA records need not even come from DNS.  They can, for
+     example, be used to implement local end-entity certificate or
+     trust-anchor "pinning", where the "pin" data takes the form
+     of TLSA records, which can augment or replace verification
+     based on the usual WebPKI public certification authorities.
+     [Viktor Dukhovni]
+
+  *) Revert default OPENSSL_NO_DEPRECATED setting.  Instead OpenSSL
+     continues to support deprecated interfaces in default builds.
+     However, applications are strongly advised to compile their
+     source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides
+     the declarations of all interfaces deprecated in 0.9.8, 1.0.0
+     or the 1.1.0 releases.
+
+     In environments in which all applications have been ported to
+     not use any deprecated interfaces OpenSSL's Configure script
+     should be used with the --api=1.1.0 option to entirely remove
+     support for the deprecated features from the library and
+     unconditionally disable them in the installed headers.
+     Essentially the same effect can be achieved with the "no-deprecated"
+     argument to Configure, except that this will always restrict
+     the build to just the latest API, rather than a fixed API
+     version.
+
+     As applications are ported to future revisions of the API,
+     they should update their compile-time OPENSSL_API_COMPAT define
+     accordingly, but in most cases should be able to continue to
+     compile with later releases.
+
+     The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are
+     0x10000000L and 0x00908000L, respectively.  However those
+     versions did not support the OPENSSL_API_COMPAT feature, and
+     so applications are not typically tested for explicit support
+     of just the undeprecated features of either release.
+     [Viktor Dukhovni]
+
+  *) Add support for setting the minimum and maximum supported protocol.
+     It can bet set via the SSL_set_min_proto_version() and
+     SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and
+     MaxProtcol.  It's recommended to use the new APIs to disable
+     protocols instead of disabling individual protocols using
+     SSL_set_options() or SSL_CONF's Protocol.  This change also
+     removes support for disabling TLS 1.2 in the OpenSSL TLS
+     client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT.
+     [Kurt Roeckx]
+
+  *) Support for ChaCha20 and Poly1305 added to libcrypto and libssl.
+     [Andy Polyakov]
+
+  *) New EC_KEY_METHOD, this replaces the older ECDSA_METHOD and ECDH_METHOD
+     and integrates ECDSA and ECDH functionality into EC. Implementations can
+     now redirect key generation and no longer need to convert to or from
+     ECDSA_SIG format.
+
+     Note: the ecdsa.h and ecdh.h headers are now no longer needed and just
+     include the ec.h header file instead.
+     [Steve Henson]
+
+  *) Remove support for all 40 and 56 bit ciphers.  This includes all the export
+     ciphers who are no longer supported and drops support the ephemeral RSA key
+     exchange. The LOW ciphers currently doesn't have any ciphers in it.
+     [Kurt Roeckx]
+
+  *) Made EVP_MD_CTX, EVP_MD, EVP_CIPHER_CTX, EVP_CIPHER and HMAC_CTX
+     opaque.  For HMAC_CTX, the following constructors and destructors
+     were added:
+
+        HMAC_CTX *HMAC_CTX_new(void);
+        void HMAC_CTX_free(HMAC_CTX *ctx);
+
+     For EVP_MD and EVP_CIPHER, complete APIs to create, fill and
+     destroy such methods has been added.  See EVP_MD_meth_new(3) and
+     EVP_CIPHER_meth_new(3) for documentation.
+
+     Additional changes:
+     1) EVP_MD_CTX_cleanup(), EVP_CIPHER_CTX_cleanup() and
+        HMAC_CTX_cleanup() were removed.  HMAC_CTX_reset() and
+        EVP_MD_CTX_reset() should be called instead to reinitialise
+        an already created structure.
+     2) For consistency with the majority of our object creators and
+        destructors, EVP_MD_CTX_(create|destroy) were renamed to
+        EVP_MD_CTX_(new|free).  The old names are retained as macros
+        for deprecated builds.
+     [Richard Levitte]
+
+  *) Added ASYNC support. Libcrypto now includes the async sub-library to enable
+     cryptographic operations to be performed asynchronously as long as an
+     asynchronous capable engine is used. See the ASYNC_start_job() man page for
+     further details. Libssl has also had this capability integrated with the
+     introduction of the new mode SSL_MODE_ASYNC and associated error
+     SSL_ERROR_WANT_ASYNC. See the SSL_CTX_set_mode() and SSL_get_error() man
+     pages. This work was developed in partnership with Intel Corp.
+     [Matt Caswell]
+
+  *) SSL_{CTX_}set_ecdh_auto() has been removed and ECDH is support is
+     always enabled now.  If you want to disable the support you should
+     exclude it using the list of supported ciphers. This also means that the
+     "-no_ecdhe" option has been removed from s_server.
+     [Kurt Roeckx]
+
+  *) SSL_{CTX}_set_tmp_ecdh() which can set 1 EC curve now internally calls
+     SSL_{CTX_}set1_curves() which can set a list.
+     [Kurt Roeckx]
+
+  *) Remove support for SSL_{CTX_}set_tmp_ecdh_callback().  You should set the
+     curve you want to support using SSL_{CTX_}set1_curves().
+     [Kurt Roeckx]
+
+  *) State machine rewrite. The state machine code has been significantly
+     refactored in order to remove much duplication of code and solve issues
+     with the old code (see ssl/statem/README for further details). This change
+     does have some associated API changes. Notably the SSL_state() function
+     has been removed and replaced by SSL_get_state which now returns an
+     "OSSL_HANDSHAKE_STATE" instead of an int. SSL_set_state() has been removed
+     altogether. The previous handshake states defined in ssl.h and ssl3.h have
+     also been removed.
+     [Matt Caswell]
+
+  *) All instances of the string "ssleay" in the public API were replaced
+     with OpenSSL (case-matching; e.g., OPENSSL_VERSION for #define's)
+     Some error codes related to internal RSA_eay API's were renamed.
+     [Rich Salz]
+
+  *) The demo files in crypto/threads were moved to demo/threads.
+     [Rich Salz]
+
+  *) Removed obsolete engines: 4758cca, aep, atalla, cswift, nuron, gmp,
+     sureware and ubsec.
+     [Matt Caswell, Rich Salz]
+
+  *) New ASN.1 embed macro.
+
+     New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
+     structure is not allocated: it is part of the parent. That is instead of
+
+     FOO *x;
+
+     it must be:
+
+     FOO x;
+
+     This reduces memory fragmentation and make it impossible to accidentally
+     set a mandatory field to NULL.
+
+     This currently only works for some fields specifically a SEQUENCE, CHOICE,
+     or ASN1_STRING type which is part of a parent SEQUENCE. Since it is
+     equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or
+     SEQUENCE OF.
+     [Steve Henson]
+
+  *) Remove EVP_CHECK_DES_KEY, a compile-time option that never compiled.
+     [Emilia Käsper]
+
+  *) Removed DES and RC4 ciphersuites from DEFAULT. Also removed RC2 although
+     in 1.0.2 EXPORT was already removed and the only RC2 ciphersuite is also
+     an EXPORT one. COMPLEMENTOFDEFAULT has been updated accordingly to add
+     DES and RC4 ciphersuites.
+     [Matt Caswell]
+
+  *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+     This changes the decoding behaviour for some invalid messages,
+     though the change is mostly in the more lenient direction, and
+     legacy behaviour is preserved as much as possible.
+     [Emilia Käsper]
+
+  *) Fix no-stdio build.
+    [ David Woodhouse <David.Woodhouse@intel.com> and also
+      Ivan Nestlerode <ivan.nestlerode@sonos.com> ]
+
+  *) New testing framework
+     The testing framework has been largely rewritten and is now using
+     perl and the perl modules Test::Harness and an extended variant of
+     Test::More called OpenSSL::Test to do its work.  All test scripts in
+     test/ have been rewritten into test recipes, and all direct calls to
+     executables in test/Makefile have become individual recipes using the
+     simplified testing OpenSSL::Test::Simple.
+
+     For documentation on our testing modules, do:
+

+
+     [Richard Levitte]
+
+  *) Revamped memory debug; only -DCRYPTO_MDEBUG and -DCRYPTO_MDEBUG_ABORT
+     are used; the latter aborts on memory leaks (usually checked on exit).
+     Some undocumented "set malloc, etc., hooks" functions were removed
+     and others were changed.  All are now documented.
+     [Rich Salz]
+
+  *) In DSA_generate_parameters_ex, if the provided seed is too short,
+     return an error
+     [Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
+
+  *) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites
+     from RFC4279, RFC4785, RFC5487, RFC5489.
+
+     Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the
+     original RSA_PSK patch.
+     [Steve Henson]
+
+  *) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay
+     era flag was never set throughout the codebase (only read). Also removed
+     SSL3_FLAGS_POP_BUFFER which was only used if
+     SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set.
+     [Matt Caswell]
+
+  *) Changed the default name options in the "ca", "crl", "req" and "x509"
+     to be "oneline" instead of "compat".
+     [Richard Levitte]
+
+  *) Remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is SSLeay legacy, we're
+     not aware of clients that still exhibit this bug, and the workaround
+     hasn't been working properly for a while.
+     [Emilia Käsper]
+
+  *) The return type of BIO_number_read() and BIO_number_written() as well as
+     the corresponding num_read and num_write members in the BIO structure has
+     changed from unsigned long to uint64_t. On platforms where an unsigned
+     long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is
+     transferred.
+     [Matt Caswell]
+
+  *) Given the pervasive nature of TLS extensions it is inadvisable to run
+     OpenSSL without support for them. It also means that maintaining
+     the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
+     not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed.
+     [Matt Caswell]
+
+  *) Removed support for the two export grade static DH ciphersuites
+     EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
+     were newly added (along with a number of other static DH ciphersuites) to
+     1.0.2. However the two export ones have *never* worked since they were
+     introduced. It seems strange in any case to be adding new export
+     ciphersuites, and given "logjam" it also does not seem correct to fix them.
+     [Matt Caswell]
+
+  *) Version negotiation has been rewritten. In particular SSLv23_method(),
+     SSLv23_client_method() and SSLv23_server_method() have been deprecated,
+     and turned into macros which simply call the new preferred function names
+     TLS_method(), TLS_client_method() and TLS_server_method(). All new code
+     should use the new names instead. Also as part of this change the ssl23.h
+     header file has been removed.
+     [Matt Caswell]
+
+  *) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This
+     code and the associated standard is no longer considered fit-for-purpose.
+     [Matt Caswell]
+
+  *) RT2547 was closed.  When generating a private key, try to make the
+     output file readable only by the owner.  This behavior change might
+     be noticeable when interacting with other software.
+
+  *) Documented all exdata functions.  Added CRYPTO_free_ex_index.
+     Added a test.
+     [Rich Salz]
+
+  *) Added HTTP GET support to the ocsp command.
+     [Rich Salz]
+
+  *) Changed default digest for the dgst and enc commands from MD5 to
+     sha256
+     [Rich Salz]
+
+  *) RAND_pseudo_bytes has been deprecated. Users should use RAND_bytes instead.
+     [Matt Caswell]

+
+  *) All libssl internal structures have been removed from the public header
+     files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is
+     now redundant). Users should not attempt to access internal structures
+     directly. Instead they should use the provided API functions.
+     [Matt Caswell]
+
+  *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.
+     Access to deprecated functions can be re-enabled by running config with
+     "enable-deprecated". In addition applications wishing to use deprecated
+     functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
+     will, by default, disable some transitive includes that previously existed
+     in the header files (e.g. ec.h will no longer, by default, include bn.h)
+     [Matt Caswell]
+
+  *) Added support for OCB mode. OpenSSL has been granted a patent license
+     compatible with the OpenSSL license for use of OCB. Details are available
+     at https://www.openssl.org/source/OCB-patent-grant-OpenSSL.pdf. Support
+     for OCB can be removed by calling config with no-ocb.

+
+  *) Experimental encrypt-then-mac support.
+    
+     Experimental support for encrypt then mac from
+     draft-gutmann-tls-encrypt-then-mac-02.txt
+
+     To enable it set the appropriate extension number (0x42 for the test
+     server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42
+ 
+     For non-compliant peers (i.e. just about everything) this should have no
+     effect.
+
+     WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.
+
+     [Steve Henson]
+
+  *) Add EVP support for key wrapping algorithms, to avoid problems with
+     existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
+     the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
+     algorithms and include tests cases.
+     [Steve Henson]
+
+  *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
+     enveloped data.
+     [Steve Henson]
+
+  *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
+     MGF1 digest and OAEP label.
+     [Steve Henson]
+
+  *) Make openssl verify return errors.
+     [Chris Palmer <palmer@google.com> and Ben Laurie]
+
+  *) New function ASN1_TIME_diff to calculate the difference between two
+     ASN1_TIME structures or one structure and the current time.
+     [Steve Henson]
+
+  *) Update fips_test_suite to support multiple command line options. New
+     test to induce all self test errors in sequence and check expected
+     failures.
+     [Steve Henson]
+
+  *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
+     sign or verify all in one operation.
+     [Steve Henson]
+
+  *) Add fips_algvs: a multicall fips utility incorporating all the algorithm
+     test programs and fips_test_suite. Includes functionality to parse
+     the minimal script output of fipsalgest.pl directly.
+     [Steve Henson]
+
+  *) Add authorisation parameter to FIPS_module_mode_set().
+     [Steve Henson]
+
+  *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.
+     [Steve Henson]
+
+  *) Use separate DRBG fields for internal and external flags. New function
+     FIPS_drbg_health_check() to perform on demand health checking. Add
+     generation tests to fips_test_suite with reduced health check interval to 
+     demonstrate periodic health checking. Add "nodh" option to
+     fips_test_suite to skip very slow DH test.
+     [Steve Henson]
+
+  *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
+     based on NID.
+     [Steve Henson]
+
+  *) More extensive health check for DRBG checking many more failure modes.
+     New function FIPS_selftest_drbg_all() to handle every possible DRBG
+     combination: call this in fips_test_suite.
+     [Steve Henson]
+
+  *) Add support for canonical generation of DSA parameter 'g'. See 
+     FIPS 186-3 A.2.3.
+
+  *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
+     POST to handle HMAC cases.
+     [Steve Henson]
+
+  *) Add functions FIPS_module_version() and FIPS_module_version_text()
+     to return numerical and string versions of the FIPS module number.
+     [Steve Henson]
+
+  *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
+     FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
+     outside the validated module in the FIPS capable OpenSSL.
+     [Steve Henson]
+
+  *) Minor change to DRBG entropy callback semantics. In some cases
+     there is no multiple of the block length between min_len and
+     max_len. Allow the callback to return more than max_len bytes
+     of entropy but discard any extra: it is the callback's responsibility
+     to ensure that the extra data discarded does not impact the
+     requested amount of entropy.
+     [Steve Henson]
+
+  *) Add PRNG security strength checks to RSA, DSA and ECDSA using 
+     information in FIPS186-3, SP800-57 and SP800-131A.
+     [Steve Henson]
+
+  *) CCM support via EVP. Interface is very similar to GCM case except we
+     must supply all data in one chunk (i.e. no update, final) and the
+     message length must be supplied if AAD is used. Add algorithm test
+     support.
+     [Steve Henson]
+
+  *) Initial version of POST overhaul. Add POST callback to allow the status
+     of POST to be monitored and/or failures induced. Modify fips_test_suite
+     to use callback. Always run all selftests even if one fails.
+     [Steve Henson]
+
+  *) XTS support including algorithm test driver in the fips_gcmtest program.
+     Note: this does increase the maximum key length from 32 to 64 bytes but
+     there should be no binary compatibility issues as existing applications
+     will never use XTS mode.
+     [Steve Henson]
+
+  *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
+     to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
+     performs algorithm blocking for unapproved PRNG types. Also do not
+     set PRNG type in FIPS_mode_set(): leave this to the application.
+     Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
+     the standard OpenSSL PRNG: set additional data to a date time vector.
+     [Steve Henson]
+
+  *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
+     This shouldn't present any incompatibility problems because applications
+     shouldn't be using these directly and any that are will need to rethink
+     anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
+     [Steve Henson]
+
+  *) Extensive self tests and health checking required by SP800-90 DRBG.
+     Remove strength parameter from FIPS_drbg_instantiate and always
+     instantiate at maximum supported strength.
+     [Steve Henson]
+
+  *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
+     [Steve Henson]
+
+  *) New algorithm test program fips_dhvs to handle DH primitives only testing.
+     [Steve Henson]
+
+  *) New function DH_compute_key_padded() to compute a DH key and pad with
+     leading zeroes if needed: this complies with SP800-56A et al.
+     [Steve Henson]
+
+  *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
+     anything, incomplete, subject to change and largely untested at present.
+     [Steve Henson]
+
+  *) Modify fipscanisteronly build option to only build the necessary object
+     files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
+     [Steve Henson]
+
+  *) Add experimental option FIPSSYMS to give all symbols in
+     fipscanister.o and FIPS or fips prefix. This will avoid
+     conflicts with future versions of OpenSSL. Add perl script
+     util/fipsas.pl to preprocess assembly language source files
+     and rename any affected symbols.
+     [Steve Henson]
+
+  *) Add selftest checks and algorithm block of non-fips algorithms in
+     FIPS mode. Remove DES2 from selftests.
+     [Steve Henson]
+
+  *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
+     return internal method without any ENGINE dependencies. Add new
+     tiny fips sign and verify functions.
+     [Steve Henson]
+
+  *) New build option no-ec2m to disable characteristic 2 code.
+     [Steve Henson]
+
+  *) New build option "fipscanisteronly". This only builds fipscanister.o
+     and (currently) associated fips utilities. Uses the file Makefile.fips
+     instead of Makefile.org as the prototype.
+     [Steve Henson]
+
+  *) Add some FIPS mode restrictions to GCM. Add internal IV generator.
+     Update fips_gcmtest to use IV generator.
+     [Steve Henson]
+
+  *) Initial, experimental EVP support for AES-GCM. AAD can be input by
+     setting output buffer to NULL. The *Final function must be
+     called although it will not retrieve any additional data. The tag
+     can be set or retrieved with a ctrl. The IV length is by default 12
+     bytes (96 bits) but can be set to an alternative value. If the IV
+     length exceeds the maximum IV length (currently 16 bytes) it cannot be
+     set before the key. 
+     [Steve Henson]
+
+  *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
+     underlying do_cipher function handles all cipher semantics itself
+     including padding and finalisation. This is useful if (for example)
+     an ENGINE cipher handles block padding itself. The behaviour of
+     do_cipher is subtly changed if this flag is set: the return value
+     is the number of characters written to the output buffer (zero is
+     no longer an error code) or a negative error code. Also if the
+     input buffer is NULL and length 0 finalisation should be performed.
+     [Steve Henson]
+
+  *) If a candidate issuer certificate is already part of the constructed
+     path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
+     [Steve Henson]
+
+  *) Improve forward-security support: add functions
+
+       void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
+       void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
+
+     for use by SSL/TLS servers; the callback function will be called whenever a
+     new session is created, and gets to decide whether the session may be
+     cached to make it resumable (return 0) or not (return 1).  (As by the
+     SSL/TLS protocol specifications, the session_id sent by the server will be
+     empty to indicate that the session is not resumable; also, the server will
+     not generate RFC 4507 (RFC 5077) session tickets.)
+
+     A simple reasonable callback implementation is to return is_forward_secure.
+     This parameter will be set to 1 or 0 depending on the ciphersuite selected
+     by the SSL/TLS server library, indicating whether it can provide forward
+     security.

+     Add CMAC pkey methods.
+     [Steve Henson]
+
+  *) Experimental renegotiation in s_server -www mode. If the client 
+     browses /reneg connection is renegotiated. If /renegcert it is
+     renegotiated requesting a certificate.
+     [Steve Henson]

+     should help trace issues which normally are only apparent in deployed
+     multi-process servers.
+     [Steve Henson]
+
+  *) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
+     return value is ignored. NB. The functions RAND_add(), RAND_seed(),
+     BIO_set_cipher() and some obscure PEM functions were changed so they
+     can now return an error. The RAND changes required a change to the
+     RAND_METHOD structure.
+     [Steve Henson]
+
+  *) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
+     a gcc attribute to warn if the result of a function is ignored. This

+     whose return value is often ignored. 
+     [Steve Henson]
+
+  *) New -noct, -requestct, -requirect and -ctlogfile options for s_client.

+  *) Prevent padding oracle in AES-NI CBC MAC check
+
+     A MITM attacker can use a padding oracle attack to decrypt traffic
+     when the connection uses an AES CBC cipher and the server support
+     AES-NI.
+
+     This issue was introduced as part of the fix for Lucky 13 padding
+     attack (CVE-2013-0169). The padding check was rewritten to be in
+     constant time by making sure that always the same bytes are read and
+     compared against either the MAC or padding bytes. But it no longer
+     checked that there was enough data to have both the MAC and padding
+     bytes.
+
+     This issue was reported by Juraj Somorovsky using TLS-Attacker.
+     (CVE-2016-2107)
+     [Kurt Roeckx]
+
+  *) Fix EVP_EncodeUpdate overflow
+
+     An overflow can occur in the EVP_EncodeUpdate() function which is used for
+     Base64 encoding of binary data. If an attacker is able to supply very large
+     amounts of input data then a length check can overflow resulting in a heap
+     corruption.
+
+     Internally to OpenSSL the EVP_EncodeUpdate() function is primarily used by
+     the PEM_write_bio* family of functions. These are mainly used within the
+     OpenSSL command line applications, so any application which processes data
+     from an untrusted source and outputs it as a PEM file should be considered
+     vulnerable to this issue. User applications that call these APIs directly
+     with large amounts of untrusted data may also be vulnerable.
+
+     This issue was reported by Guido Vranken.
+     (CVE-2016-2105)
+     [Matt Caswell]
+
+  *) Fix EVP_EncryptUpdate overflow
+
+     An overflow can occur in the EVP_EncryptUpdate() function. If an attacker
+     is able to supply very large amounts of input data after a previous call to
+     EVP_EncryptUpdate() with a partial block then a length check can overflow
+     resulting in a heap corruption. Following an analysis of all OpenSSL
+     internal usage of the EVP_EncryptUpdate() function all usage is one of two
+     forms. The first form is where the EVP_EncryptUpdate() call is known to be
+     the first called function after an EVP_EncryptInit(), and therefore that
+     specific call must be safe. The second form is where the length passed to
+     EVP_EncryptUpdate() can be seen from the code to be some small value and
+     therefore there is no possibility of an overflow. Since all instances are
+     one of these two forms, it is believed that there can be no overflows in
+     internal code due to this problem. It should be noted that
+     EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths.
+     Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances
+     of these calls have also been analysed too and it is believed there are no
+     instances in internal usage where an overflow could occur.

+
+  *) Prevent ASN.1 BIO excessive memory allocation
+
+     When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
+     a short invalid encoding can cause allocation of large amounts of memory
+     potentially consuming excessive resources or exhausting memory.
+
+     Any application parsing untrusted data through d2i BIO functions is
+     affected. The memory based functions such as d2i_X509() are *not* affected.
+     Since the memory based functions are used by the TLS library, TLS
+     applications are not affected.

+    Builds that are not configured with "enable-weak-ssl-ciphers" will not
+    provide any "EXPORT" or "LOW" strength ciphers.
+    [Viktor Dukhovni]
+
+  * Disable SSLv2 default build, default negotiation and weak ciphers.  SSLv2
+    is by default disabled at build-time.  Builds that are not configured with
+    "enable-ssl2" will not support SSLv2.  Even if "enable-ssl2" is used,
+    users who want to negotiate SSLv2 via the version-flexible SSLv23_method()
+    will need to explicitly call either of:
+
+        SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2);
+    or
+        SSL_clear_options(ssl, SSL_OP_NO_SSLv2);
+
+    as appropriate.  Even if either of those is used, or the application
+    explicitly uses the version-specific SSLv2_method() or its client and
+    server variants, SSLv2 ciphers vulnerable to exhaustive search key
+    recovery have been removed.  Specifically, the SSLv2 40-bit EXPORT

+
+     Add a new method SRP_VBASE_get1_by_user that handles the seed properly.
+
+     SRP_VBASE_get_by_user had inconsistent memory management behaviour.
+     In order to fix an unavoidable memory leak, SRP_VBASE_get_by_user
+     was changed to ignore the "fake user" SRP seed, even if the seed
+     is configured.

+
+  *) Fix BN_hex2bn/BN_dec2bn NULL pointer deref/heap corruption
+
+     In the BN_hex2bn function the number of hex digits is calculated using an
+     int value |i|. Later |bn_expand| is called with a value of |i * 4|. For
+     large values of |i| this can result in |bn_expand| not allocating any
+     memory because |i * 4| is negative. This can leave the internal BIGNUM data
+     field as NULL leading to a subsequent NULL ptr deref. For very large values
+     of |i|, the calculation |i * 4| could be a positive value smaller than |i|.
+     In this case memory is allocated to the internal BIGNUM data field, but it
+     is insufficiently sized leading to heap corruption. A similar issue exists
+     in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn
+     is ever called by user applications with very large untrusted hex/dec data.
+     This is anticipated to be a rare occurrence.
+
+     All OpenSSL internal usage of these functions use data that is not expected
+     to be untrusted, e.g. config file data or application command line
+     arguments. If user developed applications generate config file data based
+     on untrusted data then it is possible that this could also lead to security
+     consequences. This is also anticipated to be rare.

+     This issue was reported to OpenSSL by Guido Vranken.

+
+  *) Fix memory issues in BIO_*printf functions
+
+     The internal |fmtstr| function used in processing a "%s" format string in
+     the BIO_*printf functions could overflow while calculating the length of a
+     string and cause an OOB read when printing very long strings.
+
+     Additionally the internal |doapr_outch| function can attempt to write to an
+     OOB memory location (at an offset from the NULL pointer) in the event of a
+     memory allocation failure. In 1.0.2 and below this could be caused where
+     the size of a buffer to be allocated is greater than INT_MAX. E.g. this
+     could be in processing a very long "%s" format string. Memory leaks can
+     also occur.
+
+     The first issue may mask the second issue dependent on compiler behaviour.
+     These problems could enable attacks where large amounts of untrusted data
+     is passed to the BIO_*printf functions. If applications use these functions
+     in this way then they could be vulnerable. OpenSSL itself uses these
+     functions when printing out human-readable dumps of ASN.1 data. Therefore
+     applications that print this data could be vulnerable if the data is from
+     untrusted sources. OpenSSL command line applications could also be
+     vulnerable where they print out ASN.1 data, or if untrusted data is passed
+     as command line arguments.
+
+     Libssl is not considered directly vulnerable. Additionally certificates etc
+     received via remote connections via libssl are also unlikely to be able to
+     trigger these issues because of message size limits enforced within libssl.

+     This issue was reported to OpenSSL Guido Vranken.

+  *) DH small subgroups
+
+     Historically OpenSSL only ever generated DH parameters based on "safe"
+     primes. More recently (in version 1.0.2) support was provided for
+     generating X9.42 style parameter files such as those required for RFC 5114
+     support. The primes used in such files may not be "safe". Where an
+     application is using DH configured with parameters based on primes that are
+     not "safe" then an attacker could use this fact to find a peer's private
+     DH exponent. This attack requires that the attacker complete multiple
+     handshakes in which the peer uses the same private DH exponent. For example
+     this could be used to discover a TLS server's private DH exponent if it's
+     reusing the private DH exponent or it's using a static DH ciphersuite.
+
+     OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in
+     TLS. It is not on by default. If the option is not set then the server
+     reuses the same private DH exponent for the life of the server process and
+     would be vulnerable to this attack. It is believed that many popular
+     applications do set this option and would therefore not be at risk.
+
+     The fix for this issue adds an additional check where a "q" parameter is
+     available (as is the case in X9.42 based parameters). This detects the
+     only known attack, and is the only possible defense for static DH
+     ciphersuites. This could have some performance impact.
+
+     Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by
+     default and cannot be disabled. This could have some performance impact.

+  *) BN_mod_exp may produce incorrect results on x86_64
+
+     There is a carry propagating bug in the x86_64 Montgomery squaring
+     procedure. No EC algorithms are affected. Analysis suggests that attacks
+     against RSA and DSA as a result of this defect would be very difficult to
+     perform and are not believed likely. Attacks against DH are considered just
+     feasible (although very difficult) because most of the work necessary to
+     deduce information about a private key may be performed offline. The amount
+     of resources required for such an attack would be very significant and
+     likely only accessible to a limited number of attackers. An attacker would
+     additionally need online access to an unpatched system using the target
+     private key in a scenario with persistent DH parameters and a private
+     key that is shared between multiple clients. For example this can occur by
+     default in OpenSSL DHE based SSL/TLS ciphersuites.

+
+     Under certain conditions an OpenSSL 1.0.2 client can complete a handshake

+     - The client is on a platform where the PRNG has not been seeded
+     automatically, and the user has not seeded manually
+     - A protocol specific client method version has been used (i.e. not

+     - A ciphersuite is used that does not require additional random data from
+     the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA).
+
+     If the handshake succeeds then the client random that has been used will
+     have been generated from a PRNG with insufficient entropy and therefore the
+     output may be predictable.
+
+     For example using the following command with an unseeded openssl will

+
+  *) SSL_CONF* functions. These provide a common framework for application
+     configuration using configuration files or command lines.
+     [Steve Henson]
+
+  *) SSL/TLS tracing code. This parses out SSL/TLS records using the

+
+  *) New Suite B modes for TLS code. These use and enforce the requirements
+     of RFC6460: restrict ciphersuites, only permit Suite B algorithms and
+     only use Suite B curves. The Suite B modes can be set by using the
+     strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring.
+     [Steve Henson]
+
+  *) New chain verification flags for Suite B levels of security. Check

+     [Steve Henson]
+
+  *) Make tls1_check_chain return a set of flags indicating checks passed

+
+  *) If an attempt is made to use a signature algorithm not in the peer

+     [Steve Henson]
+
+  *) If server EC tmp key is not in client preference list abort handshake.
+     [Steve Henson]
+
+  *) Add support for certificate stores in CERT structure. This makes it
+     possible to have different stores per SSL structure or one store in
+     the parent SSL_CTX. Include distinct stores for certificate chain
+     verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
+     to build and store a certificate chain in CERT structure: returning
+     an error if the chain cannot be built: this will allow applications
+     to test if a chain is correctly configured.
+
+     Note: if the CERT based stores are not set then the parent SSL_CTX
+     store is used to retain compatibility with existing behaviour.
+
+     [Steve Henson]
+
+  *) New function ssl_set_client_disabled to set a ciphersuite disabled
+     mask based on the current session, check mask when sending client
+     hello and checking the requested ciphersuite.
+     [Steve Henson]
+
+  *) New ctrls to retrieve and set certificate types in a certificate
+     request message. Print out received values in s_client. If certificate
+     types is not set with custom values set sensible values based on
+     supported signature algorithms.
+     [Steve Henson]
+
+  *) Support for distinct client and server supported signature algorithms.
+     [Steve Henson]
+
+  *) Add certificate callback. If set this is called whenever a certificate
+     is required by client or server. An application can decide which
+     certificate chain to present based on arbitrary criteria: for example
+     supported signature algorithms. Add very simple example to s_server.
+     This fixes many of the problems and restrictions of the existing client
+     certificate callback: for example you can now clear an existing
+     certificate and specify the whole chain.
+     [Steve Henson]
+
+  *) Add new "valid_flags" field to CERT_PKEY structure which determines what
+     the certificate can be used for (if anything). Set valid_flags field 
+     in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
+     to have similar checks in it.
+
+     Add new "cert_flags" field to CERT structure and include a "strict mode".
+     This enforces some TLS certificate requirements (such as only permitting
+     certificate signature algorithms contained in the supported algorithms
+     extension) which some implementations ignore: this option should be used
+     with caution as it could cause interoperability issues.
+     [Steve Henson]
+
+  *) Update and tidy signature algorithm extension processing. Work out
+     shared signature algorithms based on preferences and peer algorithms
+     and print them out in s_client and s_server. Abort handshake if no
+     shared signature algorithms.
+     [Steve Henson]
+
+  *) Add new functions to allow customised supported signature algorithms
+     for SSL and SSL_CTX structures. Add options to s_client and s_server
+     to support them.
+     [Steve Henson]
+
+  *) New function SSL_certs_clear() to delete all references to certificates
+     from an SSL structure. Before this once a certificate had been added
+     it couldn't be removed.
+     [Steve Henson]
+
+  *) Integrate hostname, email address and IP address checking with certificate
+     verification. New verify options supporting checking in openssl utility.

+
+  *) Fix OCSP checking.
+     [Rob Stradling <rob.stradling@comodo.com> and Ben Laurie]
+
+  *) Initial experimental support for explicitly trusted non-root CAs. 
+     OpenSSL still tries to build a complete chain to a root but if an
+     intermediate CA has a trust setting included that is used. The first
+     setting is used: whether to trust (e.g., -addtrust option to the x509
+     utility) or reject.
+     [Steve Henson]
+
+  *) Add -trusted_first option which attempts to find certificates in the
+     trusted store even if an untrusted chain is also supplied.
+     [Steve Henson]
+
+  *) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE,
+     platform support for Linux and Android.
+     [Andy Polyakov]
+
+  *) Support for linux-x32, ILP32 environment in x86_64 framework.
+     [Andy Polyakov]
+
+  *) Experimental multi-implementation support for FIPS capable OpenSSL.
+     When in FIPS mode the approved implementations are used as normal,
+     when not in FIPS mode the internal unapproved versions are used instead.
+     This means that the FIPS capable OpenSSL isn't forced to use the
+     (often lower performance) FIPS implementations outside FIPS mode.
+     [Steve Henson]
+
+  *) Transparently support X9.42 DH parameters when calling
+     PEM_read_bio_DHparameters. This means existing applications can handle
+     the new parameter format automatically.
+     [Steve Henson]
+
+  *) Initial experimental support for X9.42 DH parameter format: mainly
+     to support use of 'q' parameter for RFC5114 parameters.
+     [Steve Henson]
+
+  *) Add DH parameters from RFC5114 including test data to dhtest.
+     [Steve Henson]
+
+  *) Support for automatic EC temporary key parameter selection. If enabled
+     the most preferred EC parameters are automatically used instead of
+     hardcoded fixed parameters. Now a server just has to call:
+     SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+     support ECDH and use the most appropriate parameters.
+     [Steve Henson]
+
+  *) Enhance and tidy EC curve and point format TLS extension code. Use
+     static structures instead of allocation if default values are used.
+     New ctrls to set curves we wish to support and to retrieve shared curves.
+     Print out shared curves in s_server. New options to s_server and s_client
+     to set list of supported curves.
+     [Steve Henson]
+
+  *) New ctrls to retrieve supported signature algorithms and 
+     supported curve values as an array of NIDs. Extend openssl utility
+     to print out received values.
+     [Steve Henson]
+
+  *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert
+     between NIDs and the more common NIST names such as "P-256". Enhance
+     ecparam utility and ECC method to recognise the NIST names for curves.
+     [Steve Henson]
+
+  *) Enhance SSL/TLS certificate chain handling to support different
+     chains for each certificate instead of one chain in the parent SSL_CTX.
+     [Steve Henson]
+
+  *) Support for fixed DH ciphersuite client authentication: where both
+     server and client use DH certificates with common parameters.
+     [Steve Henson]
+
+  *) Support for fixed DH ciphersuites: those requiring DH server
+     certificates.
+     [Steve Henson]
+
+  *) New function i2d_re_X509_tbs for re-encoding the TBS portion of
+     the certificate.
+     Note: Related 1.0.2-beta specific macros X509_get_cert_info,
+     X509_CINF_set_modified, X509_CINF_get_issuer, X509_CINF_get_extensions and

+
+  *) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS
+     message can cause a segmentation fault in OpenSSL due to a NULL pointer
+     dereference. This could lead to a Denial Of Service attack. Thanks to
+     Markus Stenberg of Cisco Systems, Inc. for reporting this issue.
+     (CVE-2014-3571)
+     [Steve Henson]
+
+  *) Fix DTLS memory leak in dtls1_buffer_record. A memory leak can occur in the
+     dtls1_buffer_record function under certain conditions. In particular this
+     could occur if an attacker sent repeated DTLS records with the same
+     sequence number but for the next epoch. The memory leak could be exploited
+     by an attacker in a Denial of Service attack through memory exhaustion.
+     Thanks to Chris Mueller for reporting this issue.
+     (CVE-2015-0206)
+     [Matt Caswell]
+
+  *) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is
+     built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl
+     method would be set to NULL which could later result in a NULL pointer
+     dereference. Thanks to Frank Schmirler for reporting this issue.

+     reporting this issue.
+     (CVE-2014-3572)
+     [Steve Henson]
+
+  *) Remove non-export ephemeral RSA code on client and server. This code
+     violated the TLS standard by allowing the use of temporary RSA keys in
+     non-export ciphersuites and could be used by a server to effectively
+     downgrade the RSA key length used to a value smaller than the server
+     certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at
+     INRIA or reporting this issue.
+     (CVE-2015-0204)
+     [Steve Henson]
+
+  *) Fixed issue where DH client certificates are accepted without verification.
+     An OpenSSL server will accept a DH certificate for client authentication
+     without the certificate verify message. This effectively allows a client to
+     authenticate without the use of a private key. This only affects servers
+     which trust a client certificate authority which issues certificates
+     containing DH keys: these are extremely rare and hardly ever encountered.
+     Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting
+     this issue.

+     [Steve Henson]
+
+  *) Ensure that the session ID context of an SSL is updated when its
+     SSL_CTX is updated via SSL_set_SSL_CTX.
+
+     The session ID context is typically set from the parent SSL_CTX,
+     and can vary with the CTX.
+     [Adam Langley]
+
+  *) Fix various certificate fingerprint issues.
+
+     By using non-DER or invalid encodings outside the signed portion of a
+     certificate the fingerprint can be changed without breaking the signature.
+     Although no details of the signed portion of the certificate can be changed
+     this can cause problems with some applications: e.g. those using the
+     certificate fingerprint for blacklists.
+
+     1. Reject signatures with non zero unused bits.
+
+     If the BIT STRING containing the signature has non zero unused bits reject
+     the signature. All current signature algorithms require zero unused bits.
+
+     2. Check certificate algorithm consistency.
+
+     Check the AlgorithmIdentifier inside TBS matches the one in the
+     certificate signature. NB: this will result in signature failure
+     errors for some broken certificates.
+
+     Thanks to Konrad Kraszewski from Google for reporting this issue.
+
+     3. Check DSA/ECDSA signatures use DER.
+
+     Re-encode DSA/ECDSA signatures and compare with the original received
+     signature. Return an error if there is a mismatch.
+
+     This will reject various cases including garbage after signature
+     (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
+     program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
+     (negative or with leading zeroes).
+
+     Further analysis was conducted and fixes were developed by Stephen Henson
+     of the OpenSSL core team.
+
+     (CVE-2014-8275)
+     [Steve Henson]
+
+   *) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect
+      results on some platforms, including x86_64. This bug occurs at random
+      with a very low probability, and is not known to be exploitable in any
+      way, though its exact impact is difficult to determine. Thanks to Pieter
+      Wuille (Blockstream) who reported this issue and also suggested an initial
+      fix. Further analysis was conducted by the OpenSSL development team and
+      Adam Langley of Google. The final fix was developed by Andy Polyakov of

+
+   *) Do not resume sessions on the server if the negotiated protocol
+      version does not match the session's version. Resuming with a different
+      version, while not strictly forbidden by the RFC, is of questionable
+      sanity and breaks all known clients.
+      [David Benjamin, Emilia Käsper]
+
+   *) Tighten handling of the ChangeCipherSpec (CCS) message: reject
+      early CCS messages during renegotiation. (Note that because
+      renegotiation is encrypted, this early CCS was not exploitable.)
+      [Emilia Käsper]
+
+   *) Tighten client-side session ticket handling during renegotiation:
+      ensure that the client only accepts a session ticket if the server sends
+      the extension anew in the ServerHello. Previously, a TLS client would
+      reuse the old extension state and thus accept a session ticket if one was
+      announced in the initial ServerHello.
+
+      Similarly, ensure that the client requires a session ticket if one
+      was advertised in the ServerHello. Previously, a TLS client would
+      ignore a missing NewSessionTicket message.

+ Changes between 1.0.1i and 1.0.1j [15 Oct 2014]
+
+  *) SRTP Memory Leak.
+
+     A flaw in the DTLS SRTP extension parsing code allows an attacker, who
+     sends a carefully crafted handshake message, to cause OpenSSL to fail
+     to free up to 64k of memory causing a memory leak. This could be
+     exploited in a Denial Of Service attack. This issue affects OpenSSL
+     1.0.1 server implementations for both SSL/TLS and DTLS regardless of
+     whether SRTP is used or configured. Implementations of OpenSSL that
+     have been compiled with OPENSSL_NO_SRTP defined are not affected.
+
+     The fix was developed by the OpenSSL team.
+     (CVE-2014-3513)
+     [OpenSSL team]
+
+  *) Session Ticket Memory Leak.
+
+     When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
+     integrity of that ticket is first verified. In the event of a session
+     ticket integrity check failing, OpenSSL will fail to free memory
+     causing a memory leak. By sending a large number of invalid session
+     tickets an attacker could exploit this issue in a Denial Of Service
+     attack.
+     (CVE-2014-3567)
+     [Steve Henson]
+
+  *) Build option no-ssl3 is incomplete.
+
+     When OpenSSL is configured with "no-ssl3" as a build option, servers
+     could accept and complete a SSL 3.0 handshake, and clients could be
+     configured to send them.
+     (CVE-2014-3568)
+     [Akamai and the OpenSSL team]
+

+     [Adam Langley, Bodo Moeller]
+
+  *) Add additional DigestInfo checks.
+ 
+     Re-encode DigestInto in DER and check against the original when
+     verifying RSA signature: this will reject any improperly encoded
+     DigestInfo structures.
+
+     Note: this is a precautionary measure and no attacks are currently known.

+
+ Changes between 1.0.1a and 1.0.1b [26 Apr 2012]
+
+  *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
+     1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
+     mean any application compiled against OpenSSL 1.0.0 headers setting
+     SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng
+     TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
+     0x10000000L Any application which was previously compiled against
+     OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
+     will need to be recompiled as a result. Letting be results in
+     inability to disable specifically TLS 1.1 and in client context,
+     in unlike event, limit maximum offered version to TLS 1.0 [see below].
+     [Steve Henson]
+
+  *) In order to ensure interoperabilty SSL_OP_NO_protocolX does not
+     disable just protocol X, but all protocols above X *if* there are
+     protocols *below* X still enabled. In more practical terms it means
+     that if application wants to disable TLS1.0 in favor of TLS1.1 and
+     above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass
+     SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to
+     client side.

+
+  *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+     [Adam Langley]
+
+  *) Workarounds for some broken servers that "hang" if a client hello
+     record length exceeds 255 bytes.
+
+     1. Do not use record version number > TLS 1.0 in initial client
+        hello: some (but not all) hanging servers will now work.
+     2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
+	the number of ciphers sent in the client hello. This should be
+        set to an even number, such as 50, for example by passing:
+        -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
+        Most broken servers should now work.
+     3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
+	TLS 1.2 client support entirely.
+     [Steve Henson]
+
+  *) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
+     [Andy Polyakov]
+
+ Changes between 1.0.0h and 1.0.1  [14 Mar 2012]
+
+  *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET
+     STRING form instead of a DigestInfo.
+     [Steve Henson]
+
+  *) The format used for MDC2 RSA signatures is inconsistent between EVP
+     and the RSA_sign/RSA_verify functions. This was made more apparent when
+     OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular
+     those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect 
+     the correct format in RSA_verify so both forms transparently work.
+     [Steve Henson]
+
+  *) Some servers which support TLS 1.0 can choke if we initially indicate
+     support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA
+     encrypted premaster secret. As a workaround use the maximum permitted
+     client version in client hello, this should keep such servers happy
+     and still work with previous versions of OpenSSL.
+     [Steve Henson]
+
+  *) Add support for TLS/DTLS heartbeats.
+     [Robin Seggelmann <seggelmann@fh-muenster.de>]
+

+     [Paul Green <Paul.Green@stratus.com>]
+

+
+  *) Make TLS-SRP code conformant with RFC 5054 API cleanup
+     (removal of unnecessary code)
+     [Peter Sylvester <peter.sylvester@edelweb.fr>]
+
+  *) Add TLS key material exporter from RFC 5705.
+     [Eric Rescorla]
+
+  *) Add DTLS-SRTP negotiation from RFC 5764.
+     [Eric Rescorla]
+

+
+  *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224,
+     NIST-P256, NIST-P521, with constant-time single point multiplication on
+     typical inputs. Compiler support for the nonstandard type __uint128_t is

+
+     Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command
+     line to include this in your build of OpenSSL, and run "make depend" (or

+
+         EC_GFp_nistp224_method()
+         EC_GFp_nistp256_method()
+         EC_GFp_nistp521_method()
+
+     EC_GROUP_new_by_curve_name() will automatically use these (while
+     EC_GROUP_new_curve_GFp() currently prefers the more flexible
+     implementations).
+     [Emilia Käsper, Adam Langley, Bodo Moeller (Google)]
+
+  *) Use type ossl_ssize_t instad of ssize_t which isn't available on

+     header file e_os2.h as it now appears in public header file cms.h
+     [Steve Henson]
+
+  *) New -sigopt option to the ca, req and x509 utilities. Additional
+     signature parameters can be passed using this option and in
+     particular PSS. 
+     [Steve Henson]
+
+  *) Add RSA PSS signing function. This will generate and set the
+     appropriate AlgorithmIdentifiers for PSS based on those in the
+     corresponding EVP_MD_CTX structure. No application support yet.
+     [Steve Henson]
+
+  *) Support for companion algorithm specific ASN1 signing routines.
+     New function ASN1_item_sign_ctx() signs a pre-initialised
+     EVP_MD_CTX structure and sets AlgorithmIdentifiers based on
+     the appropriate parameters.
+     [Steve Henson]
+
+  *) Add new algorithm specific ASN1 verification initialisation function
+     to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
+     handling will be the same no matter what EVP_PKEY_METHOD is used.
+     Add a PSS handler to support verification of PSS signatures: checked
+     against a number of sample certificates.
+     [Steve Henson]
+
+  *) Add signature printing for PSS. Add PSS OIDs.
+     [Steve Henson, Martin Kaiser <lists@kaiser.cx>]
+
+  *) Add algorithm specific signature printing. An individual ASN1 method
+     can now print out signatures instead of the standard hex dump. 
+
+     More complex signatures (e.g. PSS) can print out more meaningful
+     information. Include DSA version that prints out the signature
+     parameters r, s.
+     [Steve Henson]
+
+  *) Password based recipient info support for CMS library: implementing
+     RFC3211.
+     [Steve Henson]
+
+  *) Split password based encryption into PBES2 and PBKDF2 functions. This
+     neatly separates the code into cipher and PBE sections and is required
+     for some algorithms that split PBES2 into separate pieces (such as
+     password based CMS).
+     [Steve Henson]
+
+  *) Session-handling fixes:
+     - Fix handling of connections that are resuming with a session ID,
+       but also support Session Tickets.
+     - Fix a bug that suppressed issuing of a new ticket if the client
+       presented a ticket with an expired session.
+     - Try to set the ticket lifetime hint to something reasonable.
+     - Make tickets shorter by excluding irrelevant information.
+     - On the client side, don't ignore renewed tickets.
+     [Adam Langley, Bodo Moeller (Google)]
+
+  *) Fix PSK session representation.
+     [Bodo Moeller]
+
+  *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations.
+
+     This work was sponsored by Intel.
+     [Andy Polyakov]
+
+  *) Add GCM support to TLS library. Some custom code is needed to split
+     the IV between the fixed (from PRF) and explicit (from TLS record)
+     portions. This adds all GCM ciphersuites supported by RFC5288 and 
+     RFC5289. Generalise some AES* cipherstrings to include GCM and
+     add a special AESGCM string for GCM only.
+     [Steve Henson]
+
+  *) Expand range of ctrls for AES GCM. Permit setting invocation
+     field on decrypt and retrieval of invocation field only on encrypt.
+     [Steve Henson]
+
+  *) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support.
+     As required by RFC5289 these ciphersuites cannot be used if for
+     versions of TLS earlier than 1.2.
+     [Steve Henson]
+
+  *) For FIPS capable OpenSSL interpret a NULL default public key method
+     as unset and return the appropriate default but do *not* set the default.
+     This means we can return the appropriate method in applications that
+     switch between FIPS and non-FIPS modes.
+     [Steve Henson]
+
+  *) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an
+     ENGINE is used then we cannot handle that in the FIPS module so we
+     keep original code iff non-FIPS operations are allowed.
+     [Steve Henson]
+
+  *) Add -attime option to openssl utilities.
+     [Peter Eckersley <pde@eff.org>, Ben Laurie and Steve Henson]
+
+  *) Redirect DSA and DH operations to FIPS module in FIPS mode.
+     [Steve Henson]
+
+  *) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use
+     FIPS EC methods unconditionally for now.
+     [Steve Henson]
+
+  *) New build option no-ec2m to disable characteristic 2 code.
+     [Steve Henson]
+
+  *) Backport libcrypto audit of return value checking from 1.1.0-dev; not
+     all cases can be covered as some introduce binary incompatibilities.
+     [Steve Henson]
+
+  *) Redirect RSA operations to FIPS module including keygen,
+     encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
+     [Steve Henson]
+
+  *) Add similar low level API blocking to ciphers.
+     [Steve Henson]
+
+  *) Low level digest APIs are not approved in FIPS mode: any attempt
+     to use these will cause a fatal error. Applications that *really* want
+     to use them can use the private_* version instead.
+     [Steve Henson]
+
+  *) Redirect cipher operations to FIPS module for FIPS builds. 
+     [Steve Henson]
+
+  *) Redirect digest operations to FIPS module for FIPS builds. 
+     [Steve Henson]
+
+  *) Update build system to add "fips" flag which will link in fipscanister.o
+     for static and shared library builds embedding a signature if needed.
+     [Steve Henson]
+
+  *) Output TLS supported curves in preference order instead of numerical
+     order. This is currently hardcoded for the highest order curves first.
+     This should be configurable so applications can judge speed vs strength.
+     [Steve Henson]
+
+  *) Add TLS v1.2 server support for client authentication. 
+     [Steve Henson]
+
+  *) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
+     and enable MD5.
+     [Steve Henson]
+
+  *) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
+     FIPS modules versions.
+     [Steve Henson]
+
+  *) Add TLS v1.2 client side support for client authentication. Keep cache
+     of handshake records longer as we don't know the hash algorithm to use
+     until after the certificate request message is received.
+     [Steve Henson]
+
+  *) Initial TLS v1.2 client support. Add a default signature algorithms
+     extension including all the algorithms we support. Parse new signature
+     format in client key exchange. Relax some ECC signing restrictions for
+     TLS v1.2 as indicated in RFC5246.
+     [Steve Henson]
+
+  *) Add server support for TLS v1.2 signature algorithms extension. Switch
+     to new signature format when needed using client digest preference.
+     All server ciphersuites should now work correctly in TLS v1.2. No client
+     support yet and no support for client certificates.
+     [Steve Henson]
+
+  *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
+     to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
+     ciphersuites. At present only RSA key exchange ciphersuites work with
+     TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
+     SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
+     and version checking.
+     [Steve Henson]
+
+  *) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
+     with this defined it will not be affected by any changes to ssl internal
+     structures. Add several utility functions to allow openssl application
+     to work with OPENSSL_NO_SSL_INTERN defined.
+     [Steve Henson]
+
+  *) A long standing patch to add support for SRP from EdelWeb (Peter
+     Sylvester and Christophe Renou) was integrated.
+     [Christophe Renou <christophe.renou@edelweb.fr>, Peter Sylvester
+     <peter.sylvester@edelweb.fr>, Tom Wu <tjw@cs.stanford.edu>, and

+  *) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
+     [Steve Henson]
+
+  *) Permit abbreviated handshakes when renegotiating using the function
+     SSL_renegotiate_abbreviated().
+     [Robin Seggelmann <seggelmann@fh-muenster.de>]
+
+  *) Add call to ENGINE_register_all_complete() to
+     ENGINE_load_builtin_engines(), so some implementations get used
+     automatically instead of needing explicit application support.
+     [Steve Henson]
+
+  *) Add support for TLS key exporter as described in RFC5705.
+     [Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson]
+
+  *) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only
+     a few changes are required:
+
+       Add SSL_OP_NO_TLSv1_1 flag.
+       Add TLSv1_1 methods.
+       Update version checking logic to handle version 1.1.
+       Add explicit IV handling (ported from DTLS code).
+       Add command line options to s_client/s_server.
+     [Steve Henson]
+
+ Changes between 1.0.0g and 1.0.0h [12 Mar 2012]
+
+  *) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness
+     in CMS and PKCS7 code. When RSA decryption fails use a random key for
+     content decryption and always return the same error. Note: this attack
+     needs on average 2^20 messages so it only affects automated senders. The
+     old behaviour can be re-enabled in the CMS code by setting the
+     CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where
+     an MMA defence is not necessary.

+     [Adam Langley (Google)]
+
+  *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
+     BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
+     threads won't reuse the same blinding coefficients.
+
+     This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
+     lock to call BN_BLINDING_invert_ex, and avoids one use of

+
+ Changes between 0.9.8n and 1.0.0  [29 Mar 2010]
+

+     [Steve Henson]
+

+     output hashes compatible with older versions of OpenSSL.
+     [Willy Weisz <weisz@vcpc.univie.ac.at>]
+
+  *) Fix compression algorithm handling: if resuming a session use the
+     compression algorithm of the resumed session instead of determining
+     it from client hello again. Don't allow server to change algorithm.
+     [Steve Henson]
+
+  *) Add load_crls() function to apps tidying load_certs() too. Add option
+     to verify utility to allow additional CRLs to be included.

+
+  *) Update OCSP request code to permit adding custom headers to the request:

+     [Julia Lawall <julia@diku.dk>]
+
+  *) Update verify callback code in apps/s_cb.c and apps/verify.c, it

+     [Steve Henson]
+
+  *) Disable MD2 in the default configuration.
+     [Steve Henson]
+
+  *) In BIO_pop() and BIO_push() use the ctrl argument (which was NULL) to
+     indicate the initial BIO being pushed or popped. This makes it possible
+     to determine whether the BIO is the one explicitly called or as a result
+     of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so
+     it handles reference counts correctly and doesn't zero out the I/O bio
+     when it is not being explicitly popped. WARNING: applications which
+     included workarounds for the old buggy behaviour will need to be modified
+     or they could free up already freed BIOs.
+     [Steve Henson]
+
+  *) Extend the uni2asc/asc2uni => OPENSSL_uni2asc/OPENSSL_asc2uni
+     renaming to all platforms (within the 0.9.8 branch, this was
+     done conditionally on Netware platforms to avoid a name clash).

+
+  *) Add ECDHE and PSK support to DTLS.
+     [Michael Tuexen <tuexen@fh-muenster.de>]
+
+  *) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't
+     be used on C++.
+     [Steve Henson]
+
+  *) Add "missing" function EVP_MD_flags() (without this the only way to
+     retrieve a digest flags is by accessing the structure directly. Update
+     EVP_MD_do_all*() and EVP_CIPHER_do_all*() to include the name a digest
+     or cipher is registered as in the "from" argument. Print out all
+     registered digests in the dgst usage message instead of manually 
+     attempting to work them out.
+     [Steve Henson]
+
+  *) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello:
+     this allows the use of compression and extensions. Change default cipher
+     string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2
+     by default unless an application cipher string requests it.
+     [Steve Henson]
+
+  *) Alter match criteria in PKCS12_parse(). It used to try to use local
+     key ids to find matching certificates and keys but some PKCS#12 files
+     don't follow the (somewhat unwritten) rules and this strategy fails.
+     Now just gather all certificates together and the first private key
+     then look for the first certificate that matches the key.
+     [Steve Henson]
+
+  *) Support use of registered digest and cipher names for dgst and cipher
+     commands instead of having to add each one as a special case. So now
+     you can do:
+
+        openssl sha256 foo
+
+     as well as:
+
+        openssl dgst -sha256 foo
+
+     and this works for ENGINE based algorithms too.
+
+     [Steve Henson]
+
+  *) Update Gost ENGINE to support parameter files.
+     [Victor B. Wagner <vitus@cryptocom.ru>]
+
+  *) Support GeneralizedTime in ca utility. 
+     [Oliver Martin <oliver@volatilevoid.net>, Steve Henson]
+
+  *) Enhance the hash format used for certificate directory links. The new
+     form uses the canonical encoding (meaning equivalent names will work
+     even if they aren't identical) and uses SHA1 instead of MD5. This form
+     is incompatible with the older format and as a result c_rehash should
+     be used to rebuild symbolic links.
+     [Steve Henson]
+
+  *) Make PKCS#8 the default write format for private keys, replacing the
+     traditional format. This form is standardised, more secure and doesn't
+     include an implicit MD5 dependency.
+     [Steve Henson]
+
+  *) Add a $gcc_devteam_warn option to Configure. The idea is that any code
+     committed to OpenSSL should pass this lot as a minimum.
+     [Steve Henson]
+
+  *) Add session ticket override functionality for use by EAP-FAST.
+     [Jouni Malinen <j@w1.fi>]
+
+  *) Modify HMAC functions to return a value. Since these can be implemented
+     in an ENGINE errors can occur.
+     [Steve Henson]
+
+  *) Type-checked OBJ_bsearch_ex.
+     [Ben Laurie]
+
+  *) Type-checked OBJ_bsearch. Also some constification necessitated
+     by type-checking.  Still to come: TXT_DB, bsearch(?),
+     OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING,
+     CONF_VALUE.
+     [Ben Laurie]
+
+  *) New function OPENSSL_gmtime_adj() to add a specific number of days and
+     seconds to a tm structure directly, instead of going through OS
+     specific date routines. This avoids any issues with OS routines such
+     as the year 2038 bug. New *_adj() functions for ASN1 time structures
+     and X509_time_adj_ex() to cover the extended range. The existing
+     X509_time_adj() is still usable and will no longer have any date issues.
+     [Steve Henson]
+
+  *) Delta CRL support. New use deltas option which will attempt to locate
+     and search any appropriate delta CRLs available.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Support for CRLs partitioned by reason code. Reorganise CRL processing
+     code and add additional score elements. Validate alternate CRL paths
+     as part of the CRL checking and indicate a new error "CRL path validation
+     error" in this case. Applications wanting additional details can use
+     the verify callback and check the new "parent" field. If this is not
+     NULL CRL path validation is taking place. Existing applications won't
+     see this because it requires extended CRL support which is off by
+     default.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Support for freshest CRL extension.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Initial indirect CRL support. Currently only supported in the CRLs
+     passed directly and not via lookup. Process certificate issuer
+     CRL entry extension and lookup CRL entries by bother issuer name
+     and serial number. Check and process CRL issuer entry in IDP extension.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Add support for distinct certificate and CRL paths. The CRL issuer
+     certificate is validated separately in this case. Only enabled if
+     an extended CRL support flag is set: this flag will enable additional
+     CRL functionality in future.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Add support for policy mappings extension.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Fixes to pathlength constraint, self issued certificate handling,
+     policy processing to align with RFC3280 and PKITS tests.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Support for name constraints certificate extension. DN, email, DNS
+     and URI types are currently supported.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) To cater for systems that provide a pointer-based thread ID rather
+     than numeric, deprecate the current numeric thread ID mechanism and
+     replace it with a structure and associated callback type. This
+     mechanism allows a numeric "hash" to be extracted from a thread ID in
+     either case, and on platforms where pointers are larger than 'long',
+     mixing is done to help ensure the numeric 'hash' is usable even if it
+     can't be guaranteed unique. The default mechanism is to use "&errno"
+     as a pointer-based thread ID to distinguish between threads.
+
+     Applications that want to provide their own thread IDs should now use
+     CRYPTO_THREADID_set_callback() to register a callback that will call
+     either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().
+
+     Note that ERR_remove_state() is now deprecated, because it is tied
+     to the assumption that thread IDs are numeric.  ERR_remove_state(0)
+     to free the current thread's error state should be replaced by
+     ERR_remove_thread_state(NULL).
+
+     (This new approach replaces the functions CRYPTO_set_idptr_callback(),
+     CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
+     OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
+     application was previously providing a numeric thread callback that
+     was inappropriate for distinguishing threads, then uniqueness might
+     have been obtained with &errno that happened immediately in the
+     intermediate development versions of OpenSSL; this is no longer the
+     case, the numeric thread callback will now override the automatic use
+     of &errno.)
+     [Geoff Thorpe, with help from Bodo Moeller]
+
+  *) Initial support for different CRL issuing certificates. This covers a
+     simple case where the self issued certificates in the chain exist and
+     the real CRL issuer is higher in the existing chain.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Removed effectively defunct crypto/store from the build.
+     [Ben Laurie]
+
+  *) Revamp of STACK to provide stronger type-checking. Still to come:
+     TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE,
+     ASN1_STRING, CONF_VALUE.
+     [Ben Laurie]
+
+  *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer
+     RAM on SSL connections.  This option can save about 34k per idle SSL.
+     [Nick Mathewson]
+
+  *) Revamp of LHASH to provide stronger type-checking. Still to come:
+     STACK, TXT_DB, bsearch, qsort.
+     [Ben Laurie]
+
+  *) Initial support for Cryptographic Message Syntax (aka CMS) based
+     on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
+     support for data, signedData, compressedData, digestedData and
+     encryptedData, envelopedData types included. Scripts to check against
+     RFC4134 examples draft and interop and consistency checks of many
+     content types and variants.
+     [Steve Henson]
+
+  *) Add options to enc utility to support use of zlib compression BIO.
+     [Steve Henson]
+
+  *) Extend mk1mf to support importing of options and assembly language
+     files from Configure script, currently only included in VC-WIN32.
+     The assembly language rules can now optionally generate the source
+     files from the associated perl scripts.
+     [Steve Henson]
+
+  *) Implement remaining functionality needed to support GOST ciphersuites.
+     Interop testing has been performed using CryptoPro implementations.
+     [Victor B. Wagner <vitus@cryptocom.ru>]
+
+  *) s390x assembler pack.
+     [Andy Polyakov]
+
+  *) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU
+     "family."
+     [Andy Polyakov]
+
+  *) Implement Opaque PRF Input TLS extension as specified in
+     draft-rescorla-tls-opaque-prf-input-00.txt.  Since this is not an
+     official specification yet and no extension type assignment by
+     IANA exists, this extension (for now) will have to be explicitly
+     enabled when building OpenSSL by providing the extension number
+     to use.  For example, specify an option
+
+         -DTLSEXT_TYPE_opaque_prf_input=0x9527
+
+     to the "config" or "Configure" script to enable the extension,
+     assuming extension number 0x9527 (which is a completely arbitrary
+     and unofficial assignment based on the MD5 hash of the Internet
+     Draft).  Note that by doing so, you potentially lose
+     interoperability with other TLS implementations since these might
+     be using the same extension number for other purposes.
+
+     SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the
+     opaque PRF input value to use in the handshake.  This will create
+     an interal copy of the length-'len' string at 'src', and will
+     return non-zero for success.
+
+     To get more control and flexibility, provide a callback function
+     by using
+
+          SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb)
+          SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg)
+
+     where
+
+          int (*cb)(SSL *, void *peerinput, size_t len, void *arg);
+          void *arg;
+
+     Callback function 'cb' will be called in handshakes, and is
+     expected to use SSL_set_tlsext_opaque_prf_input() as appropriate.
+     Argument 'arg' is for application purposes (the value as given to
+     SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly
+     be provided to the callback function).  The callback function
+     has to return non-zero to report success: usually 1 to use opaque
+     PRF input just if possible, or 2 to enforce use of the opaque PRF
+     input.  In the latter case, the library will abort the handshake
+     if opaque PRF input is not successfully negotiated.
+
+     Arguments 'peerinput' and 'len' given to the callback function
+     will always be NULL and 0 in the case of a client.  A server will
+     see the client's opaque PRF input through these variables if
+     available (NULL and 0 otherwise).  Note that if the server
+     provides an opaque PRF input, the length must be the same as the
+     length of the client's opaque PRF input.
+
+     Note that the callback function will only be called when creating
+     a new session (session resumption can resume whatever was
+     previously negotiated), and will not be called in SSL 2.0
+     handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or
+     SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended
+     for applications that need to enforce opaque PRF input.
+
+     [Bodo Moeller]
+
+  *) Update ssl code to support digests other than SHA1+MD5 for handshake
+     MAC. 
+
+     [Victor B. Wagner <vitus@cryptocom.ru>]
+
+  *) Add RFC4507 support to OpenSSL. This includes the corrections in
+     RFC4507bis. The encrypted ticket format is an encrypted encoded
+     SSL_SESSION structure, that way new session features are automatically
+     supported.
+
+     If a client application caches session in an SSL_SESSION structure
+     support is transparent because tickets are now stored in the encoded
+     SSL_SESSION.
+     
+     The SSL_CTX structure automatically generates keys for ticket
+     protection in servers so again support should be possible
+     with no application modification.
+
+     If a client or server wishes to disable RFC4507 support then the option
+     SSL_OP_NO_TICKET can be set.
+
+     Add a TLS extension debugging callback to allow the contents of any client
+     or server extensions to be examined.
+
+     This work was sponsored by Google.
+     [Steve Henson]
+
+  *) Final changes to avoid use of pointer pointer casts in OpenSSL.
+     OpenSSL should now compile cleanly on gcc 4.2
+     [Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson]
+
+  *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC
+     support including streaming MAC support: this is required for GOST
+     ciphersuite support.
+     [Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson]
+
+  *) Add option -stream to use PKCS#7 streaming in smime utility. New
+     function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream()
+     to output in BER and PEM format.
+     [Steve Henson]
+
+  *) Experimental support for use of HMAC via EVP_PKEY interface. This
+     allows HMAC to be handled via the EVP_DigestSign*() interface. The
+     EVP_PKEY "key" in this case is the HMAC key, potentially allowing
+     ENGINE support for HMAC keys which are unextractable. New -mac and
+     -macopt options to dgst utility.
+     [Steve Henson]
+
+  *) New option -sigopt to dgst utility. Update dgst to use
+     EVP_Digest{Sign,Verify}*. These two changes make it possible to use
+     alternative signing parameters such as X9.31 or PSS in the dgst 
+     utility.
+     [Steve Henson]
+
+  *) Change ssl_cipher_apply_rule(), the internal function that does
+     the work each time a ciphersuite string requests enabling
+     ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or
+     removing ("!foo+bar") a class of ciphersuites: Now it maintains
+     the order of disabled ciphersuites such that those ciphersuites
+     that most recently went from enabled to disabled not only stay
+     in order with respect to each other, but also have higher priority
+     than other disabled ciphersuites the next time ciphersuites are
+     enabled again.
+
+     This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable
+     the same ciphersuites as with "HIGH" alone, but in a specific
+     order where the PSK ciphersuites come first (since they are the
+     most recently disabled ciphersuites when "HIGH" is parsed).
+
+     Also, change ssl_create_cipher_list() (using this new
+     funcionality) such that between otherwise identical
+     cihpersuites, ephemeral ECDH is preferred over ephemeral DH in
+     the default order.
+     [Bodo Moeller]
+
+  *) Change ssl_create_cipher_list() so that it automatically
+     arranges the ciphersuites in reasonable order before starting
+     to process the rule string.  Thus, the definition for "DEFAULT"
+     (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but
+     remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH".
+     This makes it much easier to arrive at a reasonable default order
+     in applications for which anonymous ciphers are OK (meaning
+     that you can't actually use DEFAULT).
+     [Bodo Moeller; suggested by Victor Duchovni]
+
+  *) Split the SSL/TLS algorithm mask (as used for ciphersuite string
+     processing) into multiple integers instead of setting
+     "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK",
+     "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer.
+     (These masks as well as the individual bit definitions are hidden
+     away into the non-exported interface ssl/ssl_locl.h, so this
+     change to the definition of the SSL_CIPHER structure shouldn't
+     affect applications.)  This give us more bits for each of these
+     categories, so there is no longer a need to coagulate AES128 and
+     AES256 into a single algorithm bit, and to coagulate Camellia128
+     and Camellia256 into a single algorithm bit, which has led to all
+     kinds of kludges.
+
+     Thus, among other things, the kludge introduced in 0.9.7m and
+     0.9.8e for masking out AES256 independently of AES128 or masking
+     out Camellia256 independently of AES256 is not needed here in 0.9.9.
+
+     With the change, we also introduce new ciphersuite aliases that
+     so far were missing: "AES128", "AES256", "CAMELLIA128", and
+     "CAMELLIA256".
+     [Bodo Moeller]
+
+  *) Add support for dsa-with-SHA224 and dsa-with-SHA256.
+     Use the leftmost N bytes of the signature input if the input is
+     larger than the prime q (with N being the size in bytes of q).
+     [Nils Larsch]
+
+  *) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses
+     it yet and it is largely untested.
+     [Steve Henson]
+
+  *) Add support for the ecdsa-with-SHA224/256/384/512 signature types.
+     [Nils Larsch]
+
+  *) Initial incomplete changes to avoid need for function casts in OpenSSL
+     some compilers (gcc 4.2 and later) reject their use. Safestack is
+     reimplemented.  Update ASN1 to avoid use of legacy functions. 
+     [Steve Henson]
+
+  *) Win32/64 targets are linked with Winsock2.
+     [Andy Polyakov]
+
+  *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected
+     to external functions. This can be used to increase CRL handling 
+     efficiency especially when CRLs are very large by (for example) storing
+     the CRL revoked certificates in a database.
+     [Steve Henson]
+
+  *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so
+     new CRLs added to a directory can be used. New command line option
+     -verify_return_error to s_client and s_server. This causes real errors
+     to be returned by the verify callback instead of carrying on no matter
+     what. This reflects the way a "real world" verify callback would behave.
+     [Steve Henson]
+
+  *) GOST engine, supporting several GOST algorithms and public key formats.
+     Kindly donated by Cryptocom.
+     [Cryptocom]
+
+  *) Partial support for Issuing Distribution Point CRL extension. CRLs
+     partitioned by DP are handled but no indirect CRL or reason partitioning
+     (yet). Complete overhaul of CRL handling: now the most suitable CRL is
+     selected via a scoring technique which handles IDP and AKID in CRLs.
+     [Steve Henson]
+
+  *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which
+     will ultimately be used for all verify operations: this will remove the
+     X509_STORE dependency on certificate verification and allow alternative
+     lookup methods.  X509_STORE based implementations of these two callbacks.
+     [Steve Henson]
+
+  *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names.
+     Modify get_crl() to find a valid (unexpired) CRL if possible.
+     [Steve Henson]
+
+  *) New function X509_CRL_match() to check if two CRLs are identical. Normally
+     this would be called X509_CRL_cmp() but that name is already used by
+     a function that just compares CRL issuer names. Cache several CRL 
+     extensions in X509_CRL structure and cache CRLDP in X509.
+     [Steve Henson]
+
+  *) Store a "canonical" representation of X509_NAME structure (ASN1 Name)
+     this maps equivalent X509_NAME structures into a consistent structure.
+     Name comparison can then be performed rapidly using memcmp().
+     [Steve Henson]
+
+  *) Non-blocking OCSP request processing. Add -timeout option to ocsp 
+     utility.
+     [Steve Henson]
+
+  *) Allow digests to supply their own micalg string for S/MIME type using
+     the ctrl EVP_MD_CTRL_MICALG.
+     [Steve Henson]
+
+  *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the
+     EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN
+     ctrl. It can then customise the structure before and/or after signing
+     if necessary.
+     [Steve Henson]
+
+  *) New function OBJ_add_sigid() to allow application defined signature OIDs
+     to be added to OpenSSLs internal tables. New function OBJ_sigid_free()
+     to free up any added signature OIDs.
+     [Steve Henson]
+
+  *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(),
+     EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal
+     digest and cipher tables. New options added to openssl utility:
+     list-message-digest-algorithms and list-cipher-algorithms.
+     [Steve Henson]
+
+  *) Change the array representation of binary polynomials: the list
+     of degrees of non-zero coefficients is now terminated with -1.
+     Previously it was terminated with 0, which was also part of the
+     value; thus, the array representation was not applicable to
+     polynomials where t^0 has coefficient zero.  This change makes
+     the array representation useful in a more general context.
+     [Douglas Stebila]
+
+  *) Various modifications and fixes to SSL/TLS cipher string
+     handling.  For ECC, the code now distinguishes between fixed ECDH
+     with RSA certificates on the one hand and with ECDSA certificates
+     on the other hand, since these are separate ciphersuites.  The
+     unused code for Fortezza ciphersuites has been removed.
+
+     For consistency with EDH, ephemeral ECDH is now called "EECDH"
+     (not "ECDHE").  For consistency with the code for DH
+     certificates, use of ECDH certificates is now considered ECDH
+     authentication, not RSA or ECDSA authentication (the latter is
+     merely the CA's signing algorithm and not actively used in the
+     protocol).
+
+     The temporary ciphersuite alias "ECCdraft" is no longer
+     available, and ECC ciphersuites are no longer excluded from "ALL"
+     and "DEFAULT".  The following aliases now exist for RFC 4492
+     ciphersuites, most of these by analogy with the DH case:
+
+         kECDHr   - ECDH cert, signed with RSA
+         kECDHe   - ECDH cert, signed with ECDSA
+         kECDH    - ECDH cert (signed with either RSA or ECDSA)
+         kEECDH   - ephemeral ECDH
+         ECDH     - ECDH cert or ephemeral ECDH
+
+         aECDH    - ECDH cert
+         aECDSA   - ECDSA cert
+         ECDSA    - ECDSA cert
+
+         AECDH    - anonymous ECDH
+         EECDH    - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")
+
+     [Bodo Moeller]
+
+  *) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
+     Use correct micalg parameters depending on digest(s) in signed message.
+     [Steve Henson]
+
+  *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
+     an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
+     [Steve Henson]
+
+  *) Initial engine support for EVP_PKEY_METHOD. New functions to permit
+     an engine to register a method. Add ENGINE lookups for methods and
+     functional reference processing.
+     [Steve Henson]
+
+  *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of
+     EVP_{Sign,Verify}* which allow an application to customise the signature
+     process.
+     [Steve Henson]
+
+  *) New -resign option to smime utility. This adds one or more signers
+     to an existing PKCS#7 signedData structure. Also -md option to use an
+     alternative message digest algorithm for signing.
+     [Steve Henson]
+
+  *) Tidy up PKCS#7 routines and add new functions to make it easier to
+     create PKCS7 structures containing multiple signers. Update smime
+     application to support multiple signers.
+     [Steve Henson]
+
+  *) New -macalg option to pkcs12 utility to allow setting of an alternative
+     digest MAC.
+     [Steve Henson]
+
+  *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.
+     Reorganize PBE internals to lookup from a static table using NIDs,
+     add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
+     EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
+     PRF which will be automatically used with PBES2.
+     [Steve Henson]
+
+  *) Replace the algorithm specific calls to generate keys in "req" with the
+     new API.
+     [Steve Henson]
+
+  *) Update PKCS#7 enveloped data routines to use new API. This is now
+     supported by any public key method supporting the encrypt operation. A
+     ctrl is added to allow the public key algorithm to examine or modify
+     the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
+     a no op.
+     [Steve Henson]
+
+  *) Add a ctrl to asn1 method to allow a public key algorithm to express
+     a default digest type to use. In most cases this will be SHA1 but some
+     algorithms (such as GOST) need to specify an alternative digest. The
+     return value indicates how strong the preference is 1 means optional and
+     2 is mandatory (that is it is the only supported type). Modify
+     ASN1_item_sign() to accept a NULL digest argument to indicate it should
+     use the default md. Update openssl utilities to use the default digest
+     type for signing if it is not explicitly indicated.
+     [Steve Henson]
+
+  *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New 
+     EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
+     signing method from the key type. This effectively removes the link
+     between digests and public key types.
+     [Steve Henson]
+
+  *) Add an OID cross reference table and utility functions. Its purpose is to
+     translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
+     rsaEncryption. This will allow some of the algorithm specific hackery
+     needed to use the correct OID to be removed. 
+     [Steve Henson]
+
+  *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
+     structures for PKCS7_sign(). They are now set up by the relevant public
+     key ASN1 method.
+     [Steve Henson]
+
+  *) Add provisional EC pkey method with support for ECDSA and ECDH.
+     [Steve Henson]
+
+  *) Add support for key derivation (agreement) in the API, DH method and
+     pkeyutl.
+     [Steve Henson]
+
+  *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
+     public and private key formats. As a side effect these add additional 
+     command line functionality not previously available: DSA signatures can be
+     generated and verified using pkeyutl and DH key support and generation in
+     pkey, genpkey.
+     [Steve Henson]
+
+  *) BeOS support.
+     [Oliver Tappe <zooey@hirschkaefer.de>]
+
+  *) New make target "install_html_docs" installs HTML renditions of the
+     manual pages.
+     [Oliver Tappe <zooey@hirschkaefer.de>]
+
+  *) New utility "genpkey" this is analogous to "genrsa" etc except it can
+     generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
+     support key and parameter generation and add initial key generation
+     functionality for RSA.
+     [Steve Henson]
+
+  *) Add functions for main EVP_PKEY_method operations. The undocumented
+     functions EVP_PKEY_{encrypt,decrypt} have been renamed to
+     EVP_PKEY_{encrypt,decrypt}_old. 
+     [Steve Henson]
+
+  *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
+     key API, doesn't do much yet.
+     [Steve Henson]
+
+  *) New function EVP_PKEY_asn1_get0_info() to retrieve information about
+     public key algorithms. New option to openssl utility:
+     "list-public-key-algorithms" to print out info.
+     [Steve Henson]
+
+  *) Implement the Supported Elliptic Curves Extension for
+     ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
+     [Douglas Stebila]
+
+  *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
+     EVP_CIPHER structures to avoid later problems in EVP_cleanup().
+     [Steve Henson]
+
+  *) New utilities pkey and pkeyparam. These are similar to algorithm specific
+     utilities such as rsa, dsa, dsaparam etc except they process any key
+     type.
+     [Steve Henson]
+
+  *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New 
+     functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
+     EVP_PKEY_print_param() to print public key data from an EVP_PKEY
+     structure.
+     [Steve Henson]
+
+  *) Initial support for pluggable public key ASN1.
+     De-spaghettify the public key ASN1 handling. Move public and private
+     key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
+     algorithm specific handling to a single module within the relevant
+     algorithm directory. Add functions to allow (near) opaque processing
+     of public and private key structures.
+     [Steve Henson]
+
+  *) Implement the Supported Point Formats Extension for
+     ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
+     [Douglas Stebila]
+
+  *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
+     for the psk identity [hint] and the psk callback functions to the
+     SSL_SESSION, SSL and SSL_CTX structure.
+     
+     New ciphersuites:
+         PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
+         PSK-AES256-CBC-SHA
+ 
+     New functions:
+         SSL_CTX_use_psk_identity_hint
+         SSL_get_psk_identity_hint
+         SSL_get_psk_identity
+         SSL_use_psk_identity_hint
+
+     [Mika Kousa and Pasi Eronen of Nokia Corporation]
+
+  *) Add RFC 3161 compliant time stamp request creation, response generation
+     and response verification functionality.
+     [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]
+
+  *) Add initial support for TLS extensions, specifically for the server_name
+     extension so far.  The SSL_SESSION, SSL_CTX, and SSL data structures now
+     have new members for a host name.  The SSL data structure has an
+     additional member SSL_CTX *initial_ctx so that new sessions can be
+     stored in that context to allow for session resumption, even after the
+     SSL has been switched to a new SSL_CTX in reaction to a client's
+     server_name extension.
+
+     New functions (subject to change):
+
+         SSL_get_servername()
+         SSL_get_servername_type()
+         SSL_set_SSL_CTX()
+
+     New CTRL codes and macros (subject to change):
+
+         SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
+                                 - SSL_CTX_set_tlsext_servername_callback()
+         SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
+                                      - SSL_CTX_set_tlsext_servername_arg()
+         SSL_CTRL_SET_TLSEXT_HOSTNAME           - SSL_set_tlsext_host_name()
+
+     openssl s_client has a new '-servername ...' option.
+
+     openssl s_server has new options '-servername_host ...', '-cert2 ...',
+     '-key2 ...', '-servername_fatal' (subject to change).  This allows
+     testing the HostName extension for a specific single host name ('-cert'
+     and '-key' remain fallbacks for handshakes without HostName
+     negotiation).  If the unrecognized_name alert has to be sent, this by
+     default is a warning; it becomes fatal with the '-servername_fatal'
+     option.
+
+     [Peter Sylvester,  Remy Allais, Christophe Renou]
+
+  *) Whirlpool hash implementation is added.
+     [Andy Polyakov]
+
+  *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
+     bn(64,32). Because of instruction set limitations it doesn't have
+     any negative impact on performance. This was done mostly in order
+     to make it possible to share assembler modules, such as bn_mul_mont
+     implementations, between 32- and 64-bit builds without hassle.
+     [Andy Polyakov]
+
+  *) Move code previously exiled into file crypto/ec/ec2_smpt.c
+     to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
+     macro.
+     [Bodo Moeller]
+
+  *) New candidate for BIGNUM assembler implementation, bn_mul_mont,
+     dedicated Montgomery multiplication procedure, is introduced.
+     BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
+     "64-bit" performance on certain 32-bit targets.
+     [Andy Polyakov]
+
+  *) New option SSL_OP_NO_COMP to disable use of compression selectively
+     in SSL structures. New SSL ctrl to set maximum send fragment size. 
+     Save memory by seeting the I/O buffer sizes dynamically instead of
+     using the maximum available value.
+     [Steve Henson]
+
+  *) New option -V for 'openssl ciphers'. This prints the ciphersuite code
+     in addition to the text details.
+     [Bodo Moeller]
+
+  *) Very, very preliminary EXPERIMENTAL support for printing of general
+     ASN1 structures. This currently produces rather ugly output and doesn't
+     handle several customised structures at all.
+     [Steve Henson]
+
+  *) Integrated support for PVK file format and some related formats such
+     as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
+     these in the 'rsa' and 'dsa' utilities.
+     [Steve Henson]
+
+  *) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
+     [Steve Henson]
+
+  *) Remove the ancient ASN1_METHOD code. This was only ever used in one
+     place for the (very old) "NETSCAPE" format certificates which are now
+     handled using new ASN1 code equivalents.
+     [Steve Henson]
+
+  *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
+     pointer and make the SSL_METHOD parameter in SSL_CTX_new,
+     SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
+     [Nils Larsch]
+
+  *) Modify CRL distribution points extension code to print out previously
+     unsupported fields. Enhance extension setting code to allow setting of
+     all fields.
+     [Steve Henson]
+
+  *) Add print and set support for Issuing Distribution Point CRL extension.
+     [Steve Henson]
+
+  *) Change 'Configure' script to enable Camellia by default.
+     [NTT]
+
+ Changes between 0.9.8m and 0.9.8n [24 Mar 2010]
+
+  *) When rejecting SSL/TLS records due to an incorrect version number, never
+     update s->server with a new major version number.  As of
+     - OpenSSL 0.9.8m if 'short' is a 16-bit type,
+     - OpenSSL 0.9.8f if 'short' is longer than 16 bits,
+     the previous behavior could result in a read attempt at NULL when
+     receiving specific incorrect SSL/TLS records once record payload
+     protection is active.  (CVE-2010-0740)
+     [Bodo Moeller, Adam Langley <agl@chromium.org>]
+
+  *) Fix for CVE-2010-0433 where some kerberos enabled versions of OpenSSL 
+     could be crashed if the relevant tables were not present (e.g. chrooted).
+     [Tomas Hoger <thoger@redhat.com>]
+
+ Changes between 0.9.8l and 0.9.8m [25 Feb 2010]
+
+  *) Always check bn_wexpend() return values for failure.  (CVE-2009-3245)
+     [Martin Olsson, Neel Mehta]
+
+  *) Fix X509_STORE locking: Every 'objs' access requires a lock (to
+     accommodate for stack sorting, always a write lock!).
+     [Bodo Moeller]
+
+  *) On some versions of WIN32 Heap32Next is very slow. This can cause
+     excessive delays in the RAND_poll(): over a minute. As a workaround
+     include a time check in the inner Heap32Next loop too.
+     [Steve Henson]
+
+  *) The code that handled flushing of data in SSL/TLS originally used the
+     BIO_CTRL_INFO ctrl to see if any data was pending first. This caused
+     the problem outlined in PR#1949. The fix suggested there however can
+     trigger problems with buggy BIO_CTRL_WPENDING (e.g. some versions
+     of Apache). So instead simplify the code to flush unconditionally.
+     This should be fine since flushing with no data to flush is a no op.
+     [Steve Henson]
+
+  *) Handle TLS versions 2.0 and later properly and correctly use the
+     highest version of TLS/SSL supported. Although TLS >= 2.0 is some way
+     off ancient servers have a habit of sticking around for a while...
+     [Steve Henson]
+
+  *) Modify compression code so it frees up structures without using the
+     ex_data callbacks. This works around a problem where some applications
+     call CRYPTO_cleanup_all_ex_data() before application exit (e.g. when
+     restarting) then use compression (e.g. SSL with compression) later.
+     This results in significant per-connection memory leaks and
+     has caused some security issues including CVE-2008-1678 and
+     CVE-2009-4355.
+     [Steve Henson]
+
+  *) Constify crypto/cast (i.e., <openssl/cast.h>): a CAST_KEY doesn't
+     change when encrypting or decrypting.
+     [Bodo Moeller]
+
+  *) Add option SSL_OP_LEGACY_SERVER_CONNECT which will allow clients to
+     connect and renegotiate with servers which do not support RI.
+     Until RI is more widely deployed this option is enabled by default.
+     [Steve Henson]
+
+  *) Add "missing" ssl ctrls to clear options and mode.
+     [Steve Henson]
+
+  *) If client attempts to renegotiate and doesn't support RI respond with
+     a no_renegotiation alert as required by RFC5746.  Some renegotiating
+     TLS clients will continue a connection gracefully when they receive
+     the alert. Unfortunately OpenSSL mishandled this alert and would hang
+     waiting for a server hello which it will never receive. Now we treat a
+     received no_renegotiation alert as a fatal error. This is because
+     applications requesting a renegotiation might well expect it to succeed
+     and would have no code in place to handle the server denying it so the
+     only safe thing to do is to terminate the connection.
+     [Steve Henson]
+
+  *) Add ctrl macro SSL_get_secure_renegotiation_support() which returns 1 if
+     peer supports secure renegotiation and 0 otherwise. Print out peer
+     renegotiation support in s_client/s_server.
+     [Steve Henson]
+
+  *) Replace the highly broken and deprecated SPKAC certification method with
+     the updated NID creation version. This should correctly handle UTF8.
+     [Steve Henson]
+
+  *) Implement RFC5746. Re-enable renegotiation but require the extension
+     as needed. Unfortunately, SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION
+     turns out to be a bad idea. It has been replaced by
+     SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION which can be set with
+     SSL_CTX_set_options(). This is really not recommended unless you
+     know what you are doing.
+     [Eric Rescorla <ekr@networkresonance.com>, Ben Laurie, Steve Henson]
+
+  *) Fixes to stateless session resumption handling. Use initial_ctx when

+
+  *) Partial backport from 0.9.9-dev:
+
+     Introduce bn_mul_mont (dedicated Montgomery multiplication

+
+     To try the 32-bit x86 assembler implementation, use Configure
+     option "enable-montasm" (which exists only for this backport).
+
+     As "enable-montasm" for 32-bit x86 disclaims code stability
+     anyway, in this constellation we activate additional code
+     backported from 0.9.9-dev for further performance improvements,
+     namely BN_from_montgomery_word.  (To enable this otherwise,

+     [Steve Henson]
+
+  *) Reverse ENGINE-internal logic for caching default ENGINE handles.
+     This was broken until now in 0.9.8 releases, such that the only way
+     a registered ENGINE could be used (assuming it initialises
+     successfully on the host) was to explicitly set it as the default
+     for the relevant algorithms. This is in contradiction with 0.9.7
+     behaviour and the documentation. With this fix, when an ENGINE is
+     registered into a given algorithm's table of implementations, the
+     'uptodate' flag is reset so that auto-discovery will be used next
+     time a new context for that algorithm attempts to select an

+     [Ian Lister (tweaked by Geoff Thorpe)]
+
+  *) Backport of CMS code to OpenSSL 0.9.8. This differs from the 0.9.9
+     implementation in the following ways:
+
+     Lack of EVP_PKEY_ASN1_METHOD means algorithm parameters have to be
+     hard coded.
+
+     Lack of BER streaming support means one pass streaming processing is
+     only supported if data is detached: setting the streaming flag is
+     ignored for embedded content.
+
+     CMS support is disabled by default and must be explicitly enabled
+     with the enable-cms configuration option.

+

+     RFC 4347 compliant client to communicate with OpenSSL server.
+     Unfortunately just fixing these incompatibilities would "cut off"

+  
+  *) Add RFC4507 support to OpenSSL. This includes the corrections in

+
+     If a client application caches session in an SSL_SESSION structure
+     support is transparent because tickets are now stored in the encoded
+     SSL_SESSION.
+     
+     The SSL_CTX structure automatically generates keys for ticket
+     protection in servers so again support should be possible
+     with no application modification.
+
+     If a client or server wishes to disable RFC4507 support then the option

+     [Steve Henson]
+
+  *) Add initial support for TLS extensions, specifically for the server_name
+     extension so far.  The SSL_SESSION, SSL_CTX, and SSL data structures now
+     have new members for a host name.  The SSL data structure has an
+     additional member SSL_CTX *initial_ctx so that new sessions can be
+     stored in that context to allow for session resumption, even after the
+     SSL has been switched to a new SSL_CTX in reaction to a client's
+     server_name extension.
+

+
+     openssl s_client has a new '-servername ...' option.
+
+     openssl s_server has new options '-servername_host ...', '-cert2 ...',

+     testing the HostName extension for a specific single host name ('-cert'
+     and '-key' remain fallbacks for handshakes without HostName
+     negotiation).  If the unrecognized_name alert has to be sent, this by

+
+  *) Mitigate branch prediction attacks, which can be practical if a
+     single processor is shared, allowing a spy process to extract

+     http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron,
+     J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL
+     and Necessary Software Countermeasures").  The core of the change
+     are new versions BN_div_no_branch() and
+     BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(),
+     respectively, which are slower, but avoid the security-relevant
+     conditional branches.  These are automatically called by BN_div()
+     and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one
+     of the input BIGNUMs.  Also, BN_is_bit_set() has been changed to
+     remove a conditional branch.
+
+     BN_FLG_CONSTTIME is the new name for the previous
+     BN_FLG_EXP_CONSTTIME flag, since it now affects more than just
+     modular exponentiation.  (Since OpenSSL 0.9.7h, setting this flag
+     in the exponent causes BN_mod_exp_mont() to use the alternative
+     implementation in BN_mod_exp_mont_consttime().)  The old name
+     remains as a deprecated alias.
+
+     Similarly, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general
+     RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses
+     constant-time implementations for more than just exponentiation.

+
+     BN_BLINDING_new() will now use BN_dup() for the modulus so that
+     the BN_BLINDING structure gets an independent copy of the
+     modulus.  This means that the previous "BIGNUM *m" argument to
+     BN_BLINDING_new() and to BN_BLINDING_create_param() now
+     essentially becomes "const BIGNUM *m", although we can't actually
+     change this in the header file before 0.9.9.  It allows
+     RSA_setup_blinding() to use BN_with_flags() on the modulus to
+     enable BN_FLG_CONSTTIME.

+  *) In the SSL/TLS server implementation, be strict about session ID
+     context matching (which matters if an application uses a single
+     external cache for different purposes).  Previously,
+     out-of-context reuse was forbidden only if SSL_VERIFY_PEER was
+     set.  This did ensure strict client verification, but meant that,
+     with applications using a single external cache for quite
+     different requirements, clients could circumvent ciphersuite
+     restrictions for a given session ID context by starting a session
+     in a different context.

+
+  *) Since AES128 and AES256 (and similarly Camellia128 and
+     Camellia256) share a single mask bit in the logic of
+     ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a

+
+  *) Fix the BIT STRING encoding generated by crypto/ec/ec_asn1.c
+     (within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters):
+     When a point or a seed is encoded in a BIT STRING, we need to
+     prevent the removal of trailing zero bits to get the proper DER
+     encoding.  (By default, crypto/asn1/a_bitstr.c assumes the case
+     of a NamedBitList, for which trailing 0 bits need to be removed.)

+     [Tavis Ormandy and Will Drewry, Google Security Team]
+
+  *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites
+     match only those.  Before that, "AES256-SHA" would be interpreted
+     as a pattern and match "AES128-SHA" too (since AES128-SHA got
+     the same strength classification in 0.9.7h) as we currently only
+     have a single AES bit in the ciphersuite description bitmap.
+     That change, however, also applied to ciphersuite strings such as
+     "RC4-MD5" that intentionally matched multiple ciphersuites --
+     namely, SSL 2.0 ciphersuites in addition to the more common ones
+     from SSL 3.0/TLS 1.0.
+
+     So we change the selection algorithm again: Naming an explicit
+     ciphersuite selects this one ciphersuite, and any other similar
+     ciphersuite (same bitmap) from *other* protocol versions.
+     Thus, "RC4-MD5" again will properly select both the SSL 2.0
+     ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite.
+
+     Since SSL 2.0 does not have any ciphersuites for which the
+     128/256 bit distinction would be relevant, this works for now.
+     The proper fix will be to use different bits for AES128 and
+     AES256, which would have avoided the problems from the beginning;
+     however, bits are scarce, so we can only do this in a new release
+     (not just a patchlevel) when we can change the SSL_CIPHER
+     definition to split the single 'unsigned long mask' bitmap into
+     multiple values to extend the available space.

+     However, please upgrade to OpenSSL 0.9.9[-dev] for

+     moved from CA.pl to the 'ca' utility with a new option -create_serial.
+
+     (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
+     number file to 1, which is bound to cause problems.  To avoid
+     the problems while respecting compatibility between different 0.9.7
+     patchlevels, 0.9.7e  employed 'openssl x509 -next_serial' in

+     we can fix the problem directly in the 'ca' utility.)
+     [Steve Henson]
+
+  *) Reduced header interdepencies by declaring more opaque objects in
+     ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
+     give fewer recursive includes, which could break lazy source code - so
+     this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
+     developers should define this symbol when building and using openssl to
+     ensure they track the recommended behaviour, interfaces, [etc], but
+     backwards-compatible behaviour prevails when this isn't defined.
+     [Geoff Thorpe]
+
+  *) New function X509_POLICY_NODE_print() which prints out policy nodes.
+     [Steve Henson]
+
+  *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
+     This will generate a random key of the appropriate length based on the 
+     cipher context. The EVP_CIPHER can provide its own random key generation
+     routine to support keys of a specific form. This is used in the des and 
+     3des routines to generate a key of the correct parity. Update S/MIME
+     code to use new functions and hence generate correct parity DES keys.
+     Add EVP_CHECK_DES_KEY #define to return an error if the key is not 
+     valid (weak or incorrect parity).
+     [Steve Henson]
+
+  *) Add a local set of CRLs that can be used by X509_verify_cert() as well
+     as looking them up. This is useful when the verified structure may contain
+     CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
+     present unless the new PKCS7_NO_CRL flag is asserted.
+     [Steve Henson]

+     syntax:
+
+     shortName = some long name, 1.2.3.4
+     [Steve Henson]
+
+  *) Reimplemented the BN_CTX implementation. There is now no more static
+     limitation on the number of variables it can handle nor the depth of the
+     "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
+     information can now expand as required, and rather than having a single
+     static array of bignums, BN_CTX now uses a linked-list of such arrays
+     allowing it to expand on demand whilst maintaining the usefulness of
+     BN_CTX's "bundling".
+     [Geoff Thorpe]
+
+  *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
+     to allow all RSA operations to function using a single BN_CTX.
+     [Geoff Thorpe]
+
+  *) Preliminary support for certificate policy evaluation and checking. This

+     of Relying Party Client Certificate Path Processing Logic" v1.07.
+     [Steve Henson]
+
+  *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and

+     associated ASN1, EVP and SSL functions and old ASN1 macros.
+     [Richard Levitte]
+
+  *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
+     and this should never fail. So the return value from the use of
+     BN_set_word() (which can fail due to needless expansion) is now deprecated;
+     if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
+     [Geoff Thorpe]
+
+  *) BN_CTX_get() should return zero-valued bignums, providing the same

+     [Geoff Thorpe, suggested by Ulf Möller]
+
+  *) Support for inhibitAnyPolicy certificate extension.
+     [Steve Henson]
+
+  *) An audit of the BIGNUM code is underway, for which debugging code is
+     enabled when BN_DEBUG is defined. This makes stricter enforcements on what
+     is considered valid when processing BIGNUMs, and causes execution to
+     assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
+     further steps are taken to deliberately pollute unused data in BIGNUM
+     structures to try and expose faulty code further on. For now, openssl will
+     (in its default mode of operation) continue to tolerate the inconsistent
+     forms that it has tolerated in the past, but authors and packagers should
+     consider trying openssl and their own applications when compiled with
+     these debugging symbols defined. It will help highlight potential bugs in
+     their own code, and will improve the test coverage for OpenSSL itself. At
+     some point, these tighter rules will become openssl's default to improve
+     maintainability, though the assert()s and other overheads will remain only
+     in debugging configurations. See bn.h for more details.
+     [Geoff Thorpe, Nils Larsch, Ulf Möller]
+
+  *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
+     that can only be obtained through BN_CTX_new() (which implicitly
+     initialises it). The presence of this function only made it possible
+     to overwrite an existing structure (and cause memory leaks).
+     [Geoff Thorpe]
+
+  *) Because of the callback-based approach for implementing LHASH as a
+     template type, lh_insert() adds opaque objects to hash-tables and
+     lh_doall() or lh_doall_arg() are typically used with a destructor callback
+     to clean up those corresponding objects before destroying the hash table
+     (and losing the object pointers). So some over-zealous constifications in
+     LHASH have been relaxed so that lh_insert() does not take (nor store) the
+     objects as "const" and the lh_doall[_arg] callback wrappers are not
+     prototyped to have "const" restrictions on the object pointers they are
+     given (and so aren't required to cast them away any more).
+     [Geoff Thorpe]
+
+  *) The tmdiff.h API was so ugly and minimal that our own timing utility
+     (speed) prefers to use its own implementation. The two implementations
+     haven't been consolidated as yet (volunteers?) but the tmdiff API has had
+     its object type properly exposed (MS_TM) instead of casting to/from "char
+     *". This may still change yet if someone realises MS_TM and "ms_time_***"
+     aren't necessarily the greatest nomenclatures - but this is what was used
+     internally to the implementation so I've used that for now.
+     [Geoff Thorpe]
+
+  *) Ensure that deprecated functions do not get compiled when
+     OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of
+     the self-tests were still using deprecated key-generation functions so
+     these have been updated also.
+     [Geoff Thorpe]
+
+  *) Reorganise PKCS#7 code to separate the digest location functionality
+     into PKCS7_find_digest(), digest addition into PKCS7_bio_add_digest().
+     New function PKCS7_set_digest() to set the digest type for PKCS#7
+     digestedData type. Add additional code to correctly generate the
+     digestedData type and add support for this type in PKCS7 initialization
+     functions.
+     [Steve Henson]
+
+  *) New function PKCS7_set0_type_other() this initializes a PKCS7 
+     structure of type "other".
+     [Steve Henson]
+
+  *) Fix prime generation loop in crypto/bn/bn_prime.pl by making
+     sure the loop does correctly stop and breaking ("division by zero")
+     modulus operations are not performed. The (pre-generated) prime
+     table crypto/bn/bn_prime.h was already correct, but it could not be
+     re-generated on some platforms because of the "division by zero"
+     situation in the script.
+     [Ralf S. Engelschall]
+
+  *) Update support for ECC-based TLS ciphersuites according to
+     draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with
+     SHA-1 now is only used for "small" curves (where the
+     representation of a field element takes up to 24 bytes); for
+     larger curves, the field element resulting from ECDH is directly
+     used as premaster secret.
+     [Douglas Stebila (Sun Microsystems Laboratories)]
+
+  *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2
+     curve secp160r1 to the tests.
+     [Douglas Stebila (Sun Microsystems Laboratories)]
+
+  *) Add the possibility to load symbols globally with DSO.
+     [Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte]
+
+  *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better
+     control of the error stack.
+     [Richard Levitte]
+
+  *) Add support for STORE in ENGINE.
+     [Richard Levitte]
+
+  *) Add the STORE type.  The intention is to provide a common interface
+     to certificate and key stores, be they simple file-based stores, or
+     HSM-type store, or LDAP stores, or...
+     NOTE: The code is currently UNTESTED and isn't really used anywhere.
+     [Richard Levitte]
+
+  *) Add a generic structure called OPENSSL_ITEM.  This can be used to
+     pass a list of arguments to any function as well as provide a way
+     for a function to pass data back to the caller.
+     [Richard Levitte]
+
+  *) Add the functions BUF_strndup() and BUF_memdup().  BUF_strndup()
+     works like BUF_strdup() but can be used to duplicate a portion of
+     a string.  The copy gets NUL-terminated.  BUF_memdup() duplicates
+     a memory area.
+     [Richard Levitte]
+
+  *) Add the function sk_find_ex() which works like sk_find(), but will
+     return an index to an element even if an exact match couldn't be
+     found.  The index is guaranteed to point at the element where the
+     searched-for key would be inserted to preserve sorting order.
+     [Richard Levitte]
+
+  *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but
+     takes an extra flags argument for optional functionality.  Currently,
+     the following flags are defined:
+
+	OBJ_BSEARCH_VALUE_ON_NOMATCH
+	This one gets OBJ_bsearch_ex() to return a pointer to the first
+	element where the comparing function returns a negative or zero
+	number.
+
+	OBJ_BSEARCH_FIRST_VALUE_ON_MATCH
+	This one gets OBJ_bsearch_ex() to return a pointer to the first
+	element where the comparing function returns zero.  This is useful
+	if there are more than one element where the comparing function
+	returns zero.
+     [Richard Levitte]
+
+  *) Make it possible to create self-signed certificates with 'openssl ca'
+     in such a way that the self-signed certificate becomes part of the
+     CA database and uses the same mechanisms for serial number generation
+     as all other certificate signing.  The new flag '-selfsign' enables
+     this functionality.  Adapt CA.sh and CA.pl.in.
+     [Richard Levitte]
+
+  *) Add functionality to check the public key of a certificate request
+     against a given private.  This is useful to check that a certificate
+     request can be signed by that key (self-signing).
+     [Richard Levitte]
+
+  *) Make it possible to have multiple active certificates with the same
+     subject in the CA index file.  This is done only if the keyword
+     'unique_subject' is set to 'no' in the main CA section (default
+     if 'CA_default') of the configuration file.  The value is saved
+     with the database itself in a separate index attribute file,
+     named like the index file with '.attr' appended to the name.
+     [Richard Levitte]
+
+  *) Generate muti valued AVAs using '+' notation in config files for
+     req and dirName.
+     [Steve Henson]
+
+  *) Support for nameConstraints certificate extension.
+     [Steve Henson]
+
+  *) Support for policyConstraints certificate extension.
+     [Steve Henson]
+
+  *) Support for policyMappings certificate extension.
+     [Steve Henson]
+
+  *) Make sure the default DSA_METHOD implementation only uses its
+     dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
+     and change its own handlers to be NULL so as to remove unnecessary
+     indirection. This lets alternative implementations fallback to the
+     default implementation more easily.
+     [Geoff Thorpe]
+
+  *) Support for directoryName in GeneralName related extensions
+     in config files.
+     [Steve Henson]
+
+  *) Make it possible to link applications using Makefile.shared.
+     Make that possible even when linking against static libraries!
+     [Richard Levitte]
+
+  *) Support for single pass processing for S/MIME signing. This now
+     means that S/MIME signing can be done from a pipe, in addition
+     cleartext signing (multipart/signed type) is effectively streaming
+     and the signed data does not need to be all held in memory.
+
+     This is done with a new flag PKCS7_STREAM. When this flag is set
+     PKCS7_sign() only initializes the PKCS7 structure and the actual signing
+     is done after the data is output (and digests calculated) in
+     SMIME_write_PKCS7().
+     [Steve Henson]
+
+  *) Add full support for -rpath/-R, both in shared libraries and
+     applications, at least on the platforms where it's known how
+     to do it.
+     [Richard Levitte]
+
+  *) In crypto/ec/ec_mult.c, implement fast point multiplication with
+     precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
+     will now compute a table of multiples of the generator that
+     makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
+     faster (notably in the case of a single point multiplication,
+     scalar * generator).
+     [Nils Larsch, Bodo Moeller]
+
+  *) IPv6 support for certificate extensions. The various extensions
+     which use the IP:a.b.c.d can now take IPv6 addresses using the
+     formats of RFC1884 2.2 . IPv6 addresses are now also displayed
+     correctly.
+     [Steve Henson]
+
+  *) Added an ENGINE that implements RSA by performing private key
+     exponentiations with the GMP library. The conversions to and from
+     GMP's mpz_t format aren't optimised nor are any montgomery forms
+     cached, and on x86 it appears OpenSSL's own performance has caught up.
+     However there are likely to be other architectures where GMP could
+     provide a boost. This ENGINE is not built in by default, but it can be
+     specified at Configure time and should be accompanied by the necessary
+     linker additions, eg;
+         ./config -DOPENSSL_USE_GMP -lgmp
+     [Geoff Thorpe]
+
+  *) "openssl engine" will not display ENGINE/DSO load failure errors when
+     testing availability of engines with "-t" - the old behaviour is
+     produced by increasing the feature's verbosity with "-tt".
+     [Geoff Thorpe]
+
+  *) ECDSA routines: under certain error conditions uninitialized BN objects
+     could be freed. Solution: make sure initialization is performed early
+     enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
+     via PR#459)
+     [Lutz Jaenicke]
+
+  *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
+     and DH_METHOD (eg. by ENGINE implementations) to override the normal
+     software implementations. For DSA and DH, parameter generation can
+     also be overridden by providing the appropriate method callbacks.
+     [Geoff Thorpe]
+
+  *) Change the "progress" mechanism used in key-generation and
+     primality testing to functions that take a new BN_GENCB pointer in
+     place of callback/argument pairs. The new API functions have "_ex"
+     postfixes and the older functions are reimplemented as wrappers for
+     the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
+     declarations of the old functions to help (graceful) attempts to
+     migrate to the new functions. Also, the new key-generation API
+     functions operate on a caller-supplied key-structure and return
+     success/failure rather than returning a key or NULL - this is to
+     help make "keygen" another member function of RSA_METHOD etc.
+
+     Example for using the new callback interface:
+
+          int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
+          void *my_arg = ...;
+          BN_GENCB my_cb;
+
+          BN_GENCB_set(&my_cb, my_callback, my_arg);
+
+          return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
+          /* For the meaning of a, b in calls to my_callback(), see the
+           * documentation of the function that calls the callback.
+           * cb will point to my_cb; my_arg can be retrieved as cb->arg.
+           * my_callback should return 1 if it wants BN_is_prime_ex()
+           * to continue, or 0 to stop.
+           */
+
+     [Geoff Thorpe]
+
+  *) Change the ZLIB compression method to be stateful, and make it
+     available to TLS with the number defined in 
+     draft-ietf-tls-compression-04.txt.
+     [Richard Levitte]
+
+  *) Add the ASN.1 structures and functions for CertificatePair, which
+     is defined as follows (according to X.509_4thEditionDraftV6.pdf):
+
+     CertificatePair ::= SEQUENCE {
+        forward		[0]	Certificate OPTIONAL,
+        reverse		[1]	Certificate OPTIONAL,
+        -- at least one of the pair shall be present -- }
+
+     Also implement the PEM functions to read and write certificate
+     pairs, and defined the PEM tag as "CERTIFICATE PAIR".
+
+     This needed to be defined, mostly for the sake of the LDAP
+     attribute crossCertificatePair, but may prove useful elsewhere as
+     well.
+     [Richard Levitte]
+
+  *) Make it possible to inhibit symlinking of shared libraries in
+     Makefile.shared, for Cygwin's sake.
+     [Richard Levitte]
+
+  *) Extend the BIGNUM API by creating a function 
+          void BN_set_negative(BIGNUM *a, int neg);
+     and a macro that behave like
+          int  BN_is_negative(const BIGNUM *a);
+
+     to avoid the need to access 'a->neg' directly in applications.
+     [Nils Larsch]
+
+  *) Implement fast modular reduction for pseudo-Mersenne primes
+     used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
+     EC_GROUP_new_curve_GFp() will now automatically use this
+     if applicable.
+     [Nils Larsch <nla@trustcenter.de>]
+
+  *) Add new lock type (CRYPTO_LOCK_BN).
+     [Bodo Moeller]
+
+  *) Change the ENGINE framework to automatically load engines
+     dynamically from specific directories unless they could be
+     found to already be built in or loaded.  Move all the
+     current engines except for the cryptodev one to a new
+     directory engines/.
+     The engines in engines/ are built as shared libraries if
+     the "shared" options was given to ./Configure or ./config.
+     Otherwise, they are inserted in libcrypto.a.
+     /usr/local/ssl/engines is the default directory for dynamic
+     engines, but that can be overridden at configure time through
+     the usual use of --prefix and/or --openssldir, and at run
+     time with the environment variable OPENSSL_ENGINES.
+     [Geoff Thorpe and Richard Levitte]
+
+  *) Add Makefile.shared, a helper makefile to build shared
+     libraries.  Adapt Makefile.org.
+     [Richard Levitte]
+
+  *) Add version info to Win32 DLLs.
+     [Peter 'Luna' Runestig" <peter@runestig.com>]
+
+  *) Add new 'medium level' PKCS#12 API. Certificates and keys
+     can be added using this API to created arbitrary PKCS#12
+     files while avoiding the low level API.
+
+     New options to PKCS12_create(), key or cert can be NULL and
+     will then be omitted from the output file. The encryption
+     algorithm NIDs can be set to -1 for no encryption, the mac
+     iteration count can be set to 0 to omit the mac.
+
+     Enhance pkcs12 utility by making the -nokeys and -nocerts
+     options work when creating a PKCS#12 file. New option -nomac
+     to omit the mac, NONE can be set for an encryption algorithm.
+     New code is modified to use the enhanced PKCS12_create()
+     instead of the low level API.
+     [Steve Henson]
+
+  *) Extend ASN1 encoder to support indefinite length constructed
+     encoding. This can output sequences tags and octet strings in
+     this form. Modify pk7_asn1.c to support indefinite length
+     encoding. This is experimental and needs additional code to
+     be useful, such as an ASN1 bio and some enhanced streaming
+     PKCS#7 code.
+
+     Extend template encode functionality so that tagging is passed
+     down to the template encoder.
+     [Steve Henson]
+
+  *) Let 'openssl req' fail if an argument to '-newkey' is not
+     recognized instead of using RSA as a default.
+     [Bodo Moeller]
+
+  *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
+     As these are not official, they are not included in "ALL";
+     the "ECCdraft" ciphersuite group alias can be used to select them.
+     [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
+
+  *) Add ECDH engine support.
+     [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
+
+  *) Add ECDH in new directory crypto/ecdh/.
+     [Douglas Stebila (Sun Microsystems Laboratories)]
+
+  *) Let BN_rand_range() abort with an error after 100 iterations
+     without success (which indicates a broken PRNG).
+     [Bodo Moeller]
+
+  *) Change BN_mod_sqrt() so that it verifies that the input value
+     is really the square of the return value.  (Previously,
+     BN_mod_sqrt would show GIGO behaviour.)
+     [Bodo Moeller]
+
+  *) Add named elliptic curves over binary fields from X9.62, SECG,
+     and WAP/WTLS; add OIDs that were still missing.
+
+     [Sheueling Chang Shantz and Douglas Stebila
+     (Sun Microsystems Laboratories)]
+
+  *) Extend the EC library for elliptic curves over binary fields
+     (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
+     New EC_METHOD:
+
+          EC_GF2m_simple_method
+
+     New API functions:
+
+          EC_GROUP_new_curve_GF2m
+          EC_GROUP_set_curve_GF2m
+          EC_GROUP_get_curve_GF2m
+          EC_POINT_set_affine_coordinates_GF2m
+          EC_POINT_get_affine_coordinates_GF2m
+          EC_POINT_set_compressed_coordinates_GF2m
+
+     Point compression for binary fields is disabled by default for
+     patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
+     enable it).
+
+     As binary polynomials are represented as BIGNUMs, various members
+     of the EC_GROUP and EC_POINT data structures can be shared
+     between the implementations for prime fields and binary fields;
+     the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
+     are essentially identical to their ..._GFp counterparts.
+     (For simplicity, the '..._GFp' prefix has been dropped from
+     various internal method names.)
+
+     An internal 'field_div' method (similar to 'field_mul' and
+     'field_sqr') has been added; this is used only for binary fields.
+
+     [Sheueling Chang Shantz and Douglas Stebila
+     (Sun Microsystems Laboratories)]
+
+  *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
+     through methods ('mul', 'precompute_mult').
+
+     The generic implementations (now internally called 'ec_wNAF_mul'
+     and 'ec_wNAF_precomputed_mult') remain the default if these
+     methods are undefined.
+
+     [Sheueling Chang Shantz and Douglas Stebila
+     (Sun Microsystems Laboratories)]
+
+  *) New function EC_GROUP_get_degree, which is defined through
+     EC_METHOD.  For curves over prime fields, this returns the bit
+     length of the modulus.
+
+     [Sheueling Chang Shantz and Douglas Stebila
+     (Sun Microsystems Laboratories)]
+
+  *) New functions EC_GROUP_dup, EC_POINT_dup.
+     (These simply call ..._new  and ..._copy).
+
+     [Sheueling Chang Shantz and Douglas Stebila
+     (Sun Microsystems Laboratories)]
+
+  *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
+     Polynomials are represented as BIGNUMs (where the sign bit is not
+     used) in the following functions [macros]:  
+
+          BN_GF2m_add
+          BN_GF2m_sub             [= BN_GF2m_add]
+          BN_GF2m_mod             [wrapper for BN_GF2m_mod_arr]
+          BN_GF2m_mod_mul         [wrapper for BN_GF2m_mod_mul_arr]

+          BN_GF2m_mod_solve_quad  [wrapper for BN_GF2m_mod_solve_quad_arr]
+          BN_GF2m_cmp             [= BN_ucmp]
+
+     (Note that only the 'mod' functions are actually for fields GF(2^m).
+     BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
+
+     For some functions, an the irreducible polynomial defining a
+     field can be given as an 'unsigned int[]' with strictly
+     decreasing elements giving the indices of those bits that are set;
+     i.e., p[] represents the polynomial
+          f(t) = t^p[0] + t^p[1] + ... + t^p[k]
+     where
+          p[0] > p[1] > ... > p[k] = 0.
+     This applies to the following functions:
+
+          BN_GF2m_mod_arr
+          BN_GF2m_mod_mul_arr
+          BN_GF2m_mod_sqr_arr
+          BN_GF2m_mod_inv_arr        [wrapper for BN_GF2m_mod_inv]

+          BN_GF2m_mod_sqrt_arr
+          BN_GF2m_mod_solve_quad_arr
+          BN_GF2m_poly2arr
+          BN_GF2m_arr2poly
+
+     Conversion can be performed by the following functions:
+
+          BN_GF2m_poly2arr
+          BN_GF2m_arr2poly
+
+     bntest.c has additional tests for binary polynomial arithmetic.
+
+     Two implementations for BN_GF2m_mod_div() are available.
+     The default algorithm simply uses BN_GF2m_mod_inv() and
+     BN_GF2m_mod_mul().  The alternative algorithm is compiled in only
+     if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
+     copyright notice in crypto/bn/bn_gf2m.c before enabling it).
+
+     [Sheueling Chang Shantz and Douglas Stebila

+     functionality is disabled at compile-time.
+     [Douglas Stebila <douglas.stebila@sun.com>]
+
+  *) Change default behaviour of 'openssl asn1parse' so that more
+     information is visible when viewing, e.g., a certificate:
+
+     Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
+     mode the content of non-printable OCTET STRINGs is output in a
+     style similar to INTEGERs, but with '[HEX DUMP]' prepended to
+     avoid the appearance of a printable string.
+     [Nils Larsch <nla@trustcenter.de>]
+
+  *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access

+          EC_GROUP_set_asn1_flag()
+          EC_GROUP_get_asn1_flag()
+          EC_GROUP_set_point_conversion_form()
+          EC_GROUP_get_point_conversion_form()
+     These control ASN1 encoding details:
+     - Curves (i.e., groups) are encoded explicitly unless asn1_flag
+       has been set to OPENSSL_EC_NAMED_CURVE.
+     - Points are encoded in uncompressed form by default; options for

+          POINT_CONVERSION_UNCOMPRESSED
+          POINT_CONVERSION_HYBRID
+
+     Also add 'seed' and 'seed_len' members to EC_GROUP with access

+     [Nils Larsch <nla@trustcenter.de>]
+
+  *) Change internals of the EC library so that the functions
+          EC_GROUP_set_generator()
+          EC_GROUP_get_generator()
+          EC_GROUP_get_order()
+          EC_GROUP_get_cofactor()
+     are implemented directly in crypto/ec/ec_lib.c and not dispatched
+     to methods, which would lead to unnecessary code duplication when
+     adding different types of curves.
+     [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
+
+  *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
+     arithmetic, and such that modified wNAFs are generated
+     (which avoid length expansion in many cases).
+     [Bodo Moeller]
+
+  *) Add a function EC_GROUP_check_discriminant() (defined via
+     EC_METHOD) that verifies that the curve discriminant is non-zero.
+
+     Add a function EC_GROUP_check() that makes some sanity tests
+     on a EC_GROUP, its generator and order.  This includes
+     EC_GROUP_check_discriminant().
+     [Nils Larsch <nla@trustcenter.de>]
+
+  *) Add ECDSA in new directory crypto/ecdsa/.
+
+     Add applications 'openssl ecparam' and 'openssl ecdsa'
+     (these are based on 'openssl dsaparam' and 'openssl dsa').
+
+     ECDSA support is also included in various other files across the
+     library.  Most notably,
+     - 'openssl req' now has a '-newkey ecdsa:file' option;
+     - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
+     - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
+       d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
+       them suitable for ECDSA where domain parameters must be
+       extracted before the specific public key;
+     - ECDSA engine support has been added.
+     [Nils Larsch <nla@trustcenter.de>]
+
+  *) Include some named elliptic curves, and add OIDs from X9.62,
+     SECG, and WAP/WTLS.  Each curve can be obtained from the new
+     function
+          EC_GROUP_new_by_curve_name(),
+     and the list of available named curves can be obtained with
+          EC_get_builtin_curves().
+     Also add a 'curve_name' member to EC_GROUP objects, which can be
+     accessed via
+         EC_GROUP_set_curve_name()
+         EC_GROUP_get_curve_name()
+     [Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
+ 
+  *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
+     was actually never needed) and in BN_mul().  The removal in BN_mul()
+     required a small change in bn_mul_part_recursive() and the addition
+     of the functions bn_cmp_part_words(), bn_sub_part_words() and
+     bn_add_part_words(), which do the same thing as bn_cmp_words(),
+     bn_sub_words() and bn_add_words() except they take arrays with
+     differing sizes.

+
+ Changes between 0.9.7l and 0.9.7m  [23 Feb 2007]
+
+  *) Cleanse PEM buffers before freeing them since they may contain 
+     sensitive data.
+     [Benjamin Bennett <ben@psc.edu>]
+
+  *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that
+     a ciphersuite string such as "DEFAULT:RSA" cannot enable
+     authentication-only ciphersuites.
+     [Bodo Moeller]
+
+  *) Since AES128 and AES256 share a single mask bit in the logic of
+     ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a
+     kludge to work properly if AES128 is available and AES256 isn't.
+     [Victor Duchovni]
+
+  *) Expand security boundary to match 1.1.1 module.
+     [Steve Henson]
+
+  *) Remove redundant features: hash file source, editing of test vectors
+     modify fipsld to use external fips_premain.c signature.
+     [Steve Henson]
+
+  *) New perl script mkfipsscr.pl to create shell scripts or batch files to
+     run algorithm test programs.
+     [Steve Henson]
+
+  *) Make algorithm test programs more tolerant of whitespace.
+     [Steve Henson]
+
+  *) Have SSL/TLS server implementation tolerate "mismatched" record
+     protocol version while receiving ClientHello even if the
+     ClientHello is fragmented.  (The server can't insist on the
+     particular protocol version it has chosen before the ServerHello
+     message has informed the client about his choice.)
+     [Bodo Moeller]
+
+  *) Load error codes if they are not already present instead of using a
+     static variable. This allows them to be cleanly unloaded and reloaded.
+     [Steve Henson]
+
+ Changes between 0.9.7k and 0.9.7l  [28 Sep 2006]
+
+  *) Introduce limits to prevent malicious keys being able to
+     cause a denial of service.  (CVE-2006-2940)
+     [Steve Henson, Bodo Moeller]
+
+  *) Fix ASN.1 parsing of certain invalid structures that can result
+     in a denial of service.  (CVE-2006-2937)  [Steve Henson]
+
+  *) Fix buffer overflow in SSL_get_shared_ciphers() function. 
+     (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team]
+
+  *) Fix SSL client code which could crash if connecting to a
+     malicious SSLv2 server.  (CVE-2006-4343)
+     [Tavis Ormandy and Will Drewry, Google Security Team]
+
+  *) Change ciphersuite string processing so that an explicit
+     ciphersuite selects this one ciphersuite (so that "AES256-SHA"
+     will no longer include "AES128-SHA"), and any other similar
+     ciphersuite (same bitmap) from *other* protocol versions (so that
+     "RC4-MD5" will still include both the SSL 2.0 ciphersuite and the
+     SSL 3.0/TLS 1.0 ciphersuite).  This is a backport combining
+     changes from 0.9.8b and 0.9.8d.
+     [Bodo Moeller]
+
+ Changes between 0.9.7j and 0.9.7k  [05 Sep 2006]
+
+  *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher
+     (CVE-2006-4339)  [Ben Laurie and Google Security Team]
+
+  *) Change the Unix randomness entropy gathering to use poll() when
+     possible instead of select(), since the latter has some
+     undesirable limitations.
+     [Darryl Miles via Richard Levitte and Bodo Moeller]
+
+  *) Disable rogue ciphersuites:
+
+      - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+      - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+      - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+     The latter two were purportedly from
+     draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+     appear there.
+
+     Also deactive the remaining ciphersuites from
+     draft-ietf-tls-56-bit-ciphersuites-01.txt.  These are just as
+     unofficial, and the ID has long expired.
+     [Bodo Moeller]
+
+  *) Fix RSA blinding Heisenbug (problems sometimes occurred on
+     dual-core machines) and other potential thread-safety issues.
+     [Bodo Moeller]
+
+ Changes between 0.9.7i and 0.9.7j  [04 May 2006]
+
+  *) Adapt fipsld and the build system to link against the validated FIPS
+     module in FIPS mode.
+     [Steve Henson]
+
+  *) Fixes for VC++ 2005 build under Windows.
+     [Steve Henson]
+
+  *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make 
+     from a Windows bash shell such as MSYS. It is autodetected from the
+     "config" script when run from a VC++ environment. Modify standard VC++
+     build to use fipscanister.o from the GNU make build. 
+     [Steve Henson]
+
+ Changes between 0.9.7h and 0.9.7i  [14 Oct 2005]
+
+  *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
+     The value now differs depending on if you build for FIPS or not.
+     BEWARE!  A program linked with a shared FIPSed libcrypto can't be
+     safely run with a non-FIPSed libcrypto, as it may crash because of
+     the difference induced by this change.
+     [Andy Polyakov]
+
+ Changes between 0.9.7g and 0.9.7h  [11 Oct 2005]
+
+  *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+     (part of SSL_OP_ALL).  This option used to disable the
+     countermeasure against man-in-the-middle protocol-version
+     rollback in the SSL 2.0 server implementation, which is a bad
+     idea.  (CVE-2005-2969)
+
+     [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+     for Information Security, National Institute of Advanced Industrial
+     Science and Technology [AIST], Japan)]
+
+  *) Minimal support for X9.31 signatures and PSS padding modes. This is
+     mainly for FIPS compliance and not fully integrated at this stage.
+     [Steve Henson]
+
+  *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
+     the exponentiation using a fixed-length exponent.  (Otherwise,
+     the information leaked through timing could expose the secret key
+     after many signatures; cf. Bleichenbacher's attack on DSA with
+     biased k.)
+     [Bodo Moeller]
+
+  *) Make a new fixed-window mod_exp implementation the default for
+     RSA, DSA, and DH private-key operations so that the sequence of
+     squares and multiplies and the memory access pattern are
+     independent of the particular secret key.  This will mitigate
+     cache-timing and potential related attacks.
+
+     BN_mod_exp_mont_consttime() is the new exponentiation implementation,
+     and this is automatically used by BN_mod_exp_mont() if the new flag
+     BN_FLG_EXP_CONSTTIME is set for the exponent.  RSA, DSA, and DH
+     will use this BN flag for private exponents unless the flag
+     RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
+     DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
+
+     [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
+
+  *) Change the client implementation for SSLv23_method() and
+     SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
+     Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
+     (Previously, the SSL 2.0 backwards compatible Client Hello
+     message format would be used even with SSL_OP_NO_SSLv2.)
+     [Bodo Moeller]
+
+  *) Add support for smime-type MIME parameter in S/MIME messages which some
+     clients need.
+     [Steve Henson]
+
+  *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
+     a threadsafe manner. Modify rsa code to use new function and add calls
+     to dsa and dh code (which had race conditions before).
+     [Steve Henson]
+
+  *) Include the fixed error library code in the C error file definitions
+     instead of fixing them up at runtime. This keeps the error code
+     structures constant.
+     [Steve Henson]
+
+ Changes between 0.9.7f and 0.9.7g  [11 Apr 2005]
+
+  [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
+  OpenSSL 0.9.8.]
+
+  *) Fixes for newer kerberos headers. NB: the casts are needed because
+     the 'length' field is signed on one version and unsigned on another
+     with no (?) obvious way to tell the difference, without these VC++
+     complains. Also the "definition" of FAR (blank) is no longer included
+     nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
+     some needed definitions.
+     [Steve Henson]
+
+  *) Undo Cygwin change.
+     [Ulf Möller]
+
+  *) Added support for proxy certificates according to RFC 3820.
+     Because they may be a security thread to unaware applications,
+     they must be explicitly allowed in run-time.  See
+     docs/HOWTO/proxy_certificates.txt for further information.
+     [Richard Levitte]
+
+ Changes between 0.9.7e and 0.9.7f  [22 Mar 2005]
+
+  *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
+     server and client random values. Previously
+     (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
+     less random data when sizeof(time_t) > 4 (some 64 bit platforms).
+
+     This change has negligible security impact because:
+
+     1. Server and client random values still have 24 bytes of pseudo random
+        data.
+
+     2. Server and client random values are sent in the clear in the initial
+        handshake.
+
+     3. The master secret is derived using the premaster secret (48 bytes in
+        size for static RSA ciphersuites) as well as client server and random
+        values.
+
+     The OpenSSL team would like to thank the UK NISCC for bringing this issue
+     to our attention. 
+
+     [Stephen Henson, reported by UK NISCC]
+

+
+  *) Back-port of selected performance improvements from development
+     branch, as well as improved support for PowerPC platforms.
+     [Andy Polyakov]

+  *) Add lots of checks for memory allocation failure, error codes to indicate
+     failure and freeing up memory if a failure occurs.
+     [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
+
+  *) Add new -passin argument to dgst.
+     [Steve Henson]
+
+  *) Perform some character comparisons of different types in X509_NAME_cmp:
+     this is needed for some certificates that re-encode DNs into UTF8Strings
+     (in violation of RFC3280) and can't or won't issue name rollover
+     certificates.
+     [Steve Henson]
+
+  *) Make an explicit check during certificate validation to see that
+     the CA setting in each certificate on the chain is correct.  As a
+     side effect always do the following basic checks on extensions,
+     not just when there's an associated purpose to the check:
+
+      - if there is an unhandled critical extension (unless the user
+        has chosen to ignore this fault)
+      - if the path length has been exceeded (if one is set at all)
+      - that certain extensions fit the associated purpose (if one has
+        been given)
+     [Richard Levitte]
+
+ Changes between 0.9.7d and 0.9.7e  [25 Oct 2004]
+
+  *) Avoid a race condition when CRLs are checked in a multi threaded 
+     environment. This would happen due to the reordering of the revoked
+     entries during signature checking and serial number lookup. Now the
+     encoding is cached and the serial number sort performed under a lock.
+     Add new STACK function sk_is_sorted().
+     [Steve Henson]
+

+     [Steve Henson]
+
+  *) Various fixes to s3_pkt.c so alerts are sent properly.
+     [David Holmes <d.holmes@f5.com>]
+
+  *) Reduce the chances of duplicate issuer name and serial numbers (in
+     violation of RFC3280) using the OpenSSL certificate creation utilities.
+     This is done by creating a random 64 bit value for the initial serial
+     number when a serial number file is created or when a self signed
+     certificate is created using 'openssl req -x509'. The initial serial
+     number file is created using 'openssl x509 -next_serial' in CA.pl
+     rather than being initialized to 1.
+     [Steve Henson]
+
+ Changes between 0.9.7c and 0.9.7d  [17 Mar 2004]

+  *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
+     (CVE-2004-0112)
+     [Joe Orton, Steve Henson]   
+
+  *) Make it possible to have multiple active certificates with the same
+     subject in the CA index file.  This is done only if the keyword
+     'unique_subject' is set to 'no' in the main CA section (default
+     if 'CA_default') of the configuration file.  The value is saved
+     with the database itself in a separate index attribute file,
+     named like the index file with '.attr' appended to the name.
+     [Richard Levitte]
+
+  *) X509 verify fixes. Disable broken certificate workarounds when 
+     X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
+     keyUsage extension present. Don't accept CRLs with unhandled critical
+     extensions: since verify currently doesn't process CRL extensions this
+     rejects a CRL with *any* critical extensions. Add new verify error codes
+     for these cases.
+     [Steve Henson]
+
+  *) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
+     A clarification of RFC2560 will require the use of OCTET STRINGs and 
+     some implementations cannot handle the current raw format. Since OpenSSL
+     copies and compares OCSP nonces as opaque blobs without any attempt at
+     parsing them this should not create any compatibility issues.
+     [Steve Henson]
+
+  *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
+     calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
+     this HMAC (and other) operations are several times slower than OpenSSL

+     [Steve Henson]
+
+ Changes between 0.9.7b and 0.9.7c  [30 Sep 2003]
+
+  *) Fix various bugs revealed by running the NISCC test suite:
+
+     Stop out of bounds reads in the ASN1 code when presented with
+     invalid tags (CVE-2003-0543 and CVE-2003-0544).
+     
+     Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545).
+
+     If verify callback ignores invalid public key errors don't try to check

+
+     [Steve Henson]
+

+     [Steve Henson]
+
+  *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
+     if the server requested one: as stated in TLS 1.0 and SSL 3.0
+     specifications.
+     [Steve Henson]
+
+  *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional

+     but also for SSL 3.0 (as required by the specification).
+     [Bodo Moeller; problem pointed out by Matthias Loepfe]
+

+     when it's 512 *bits* long, not 512 bytes.
+     [Richard Levitte]
+
+  *) Change AES_cbc_encrypt() so it outputs exact multiple of
+     blocks during encryption.
+     [Richard Levitte]
+
+  *) Various fixes to base64 BIO and non blocking I/O. On write 
+     flushes were not handled properly if the BIO retried. On read
+     data was not being buffered properly and had various logic bugs.
+     This also affects blocking I/O when the data being decoded is a
+     certain size.
+     [Steve Henson]
+
+  *) Various S/MIME bugfixes and compatibility changes:
+     output correct application/pkcs7 MIME type if
+     PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
+     Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
+     of files as .eml work). Correctly handle very long lines in MIME
+     parser.
+     [Steve Henson]
+
+ Changes between 0.9.7a and 0.9.7b  [10 Apr 2003]
+
+  *) Countermeasure against the Klima-Pokorny-Rosa extension of
+     Bleichbacher's attack on PKCS #1 v1.5 padding: treat

+     in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
+     [Bodo Moeller]
+
+  *) Turn on RSA blinding by default in the default implementation
+     to avoid a timing attack. Applications that don't want it can call
+     RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
+     They would be ill-advised to do so in most cases.
+     [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
+
+  *) Change RSA blinding code so that it works when the PRNG is not
+     seeded (in this case, the secret RSA exponent is abused as
+     an unpredictable seed -- if it is not unpredictable, there
+     is no point in blinding anyway).  Make RSA blinding thread-safe
+     by remembering the creator's thread ID in rsa->blinding and
+     having all other threads use local one-time blinding factors
+     (this requires more computation than sharing rsa->blinding, but
+     avoids excessive locking; and if an RSA object is not shared
+     between threads, blinding will still be very fast).
+     [Bodo Moeller]
+
+  *) Fixed a typo bug that would cause ENGINE_set_default() to set an
+     ENGINE as defaults for all supported algorithms irrespective of
+     the 'flags' parameter. 'flags' is now honoured, so applications
+     should make sure they are passing it correctly.

+ Changes between 0.9.7 and 0.9.7a  [19 Feb 2003]
+
+  *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
+     via timing by performing a MAC computation even if incorrect

+     [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
+     Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
+     Martin Vuagnoux (EPFL, Ilion)]
+
+  *) Make the no-err option work as intended.  The intention with no-err
+     is not to have the whole error stack handling routines removed from
+     libcrypto, it's only intended to remove all the function name and
+     reason texts, thereby removing some of the footprint that may not
+     be interesting if those errors aren't displayed anyway.
+
+     NOTE: it's still possible for any application or module to have it's
+     own set of error texts inserted.  The routines are there, just not

+
+  *) Allow an application to disable the automatic SSL chain building.
+     Before this a rather primitive chain build was always performed in
+     ssl3_output_cert_chain(): an application had no way to send the 
+     correct chain if the automatic operation produced an incorrect result.
+
+     Now the chain builder is disabled if either:
+
+     1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
+
+     2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
+
+     The reasoning behind this is that an application would not want the
+     auto chain building to take place if extra chain certificates are
+     present and it might also want a means of sending no additional
+     certificates (for example the chain has two certificates and the
+     root is omitted).

+
+  *) The hw_ncipher.c engine requires dynamic locks.  Unfortunately, it

+     [Lutz Jaenicke, Bodo Moeller]
+
+  *) Add appropriate support for separate platform-dependent build
+     directories.  The recommended way to make a platform-dependent
+     build directory is the following (tested on Linux), maybe with

+
+	# Place yourself outside of the OpenSSL source tree.  In
+	# this example, the environment variable OPENSSL_SOURCE
+	# is assumed to contain the absolute OpenSSL source directory.

+
+     To be absolutely sure not to disturb the source tree, a "make clean"

+
+  *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this 
+     allows existing EVP_CIPHER_CTX structures to be reused after

+  *) Check the values of dna and dnb in bn_mul_recursive before calling

+
+  *) Add an "init" command to the ENGINE config module and auto initialize

+
+     whenever a protocol message has been completely received
+     (write_p == 0) or sent (write_p == 1).  Here 'version' is the
+     protocol version  according to which the SSL library interprets
+     the current protocol message (SSL2_VERSION, SSL3_VERSION, or

+     [Ben Laurie]
+
+  *) Add '-noemailDN' option to 'openssl ca'.  This prevents inclusion

+     [Massimiliano Pala madwolf@openca.org]
+
+  *) Change all functions with names starting with des_ to be starting
+     with DES_ instead.  Add wrappers that are compatible with libdes,
+     but are named _ossl_old_des_*.  Finally, add macros that map the
+     des_* symbols to the corresponding _ossl_old_des_* if libdes
+     compatibility is desired.  If OpenSSL 0.9.6c compatibility is
+     desired, the des_* symbols will be mapped to DES_*, with one
+     exception.
+
+     Since we provide two compatibility mappings, the user needs to
+     define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
+     compatibility is desired.  The default (i.e., when that macro
+     isn't defined) is OpenSSL 0.9.6c compatibility.
+
+     There are also macros that enable and disable the support of old
+     des functions altogether.  Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
+     and OPENSSL_DISABLE_OLD_DES_SUPPORT.  If none or both of those
+     are defined, the default will apply: to support the old des routines.
+
+     In either case, one must include openssl/des.h to get the correct
+     definitions.  Do not try to just include openssl/des_old.h, that
+     won't work.
+
+     NOTE: This is a major break of an old API into a new one.  Software
+     authors are encouraged to switch to the DES_ style functions.  Some
+     time in the future, des_old.h and the libdes compatibility functions
+     will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the

+
+  *) Test for certificates which contain unsupported critical extensions.
+     If such a certificate is found during a verify operation it is

+     by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function

+     not have to be to be initialized before the call to EVP_DigestInit() and
+     it is tidied up after a call to EVP_DigestFinal(). New function
+     EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
+     EVP_MD_CTX_copy() changed to not require the destination to be
+     initialized valid and new function EVP_MD_CTX_copy_ex() added which
+     requires the destination to be valid.
+
+     Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
+     EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
+     [Steve Henson]
+
+  *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
+     so that complete 'Handshake' protocol structures are kept in memory
+     instead of overwriting 'msg_type' and 'length' with 'body' data.
+     [Bodo Moeller]
+
+  *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
+     [Massimo Santin via Richard Levitte]
+
+  *) Major restructuring to the underlying ENGINE code. This includes
+     reduction of linker bloat, separation of pure "ENGINE" manipulation
+     (initialisation, etc) from functionality dealing with implementations
+     of specific crypto iterfaces. This change also introduces integrated
+     support for symmetric ciphers and digest implementations - so ENGINEs
+     can now accelerate these by providing EVP_CIPHER and EVP_MD
+     implementations of their own. This is detailed in crypto/engine/README
+     as it couldn't be adequately described here. However, there are a few
+     API changes worth noting - some RSA, DSA, DH, and RAND functions that
+     were changed in the original introduction of ENGINE code have now
+     reverted back - the hooking from this code to ENGINE is now a good
+     deal more passive and at run-time, operations deal directly with
+     RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
+     dereferencing through an ENGINE pointer any more. Also, the ENGINE
+     functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
+     they were not being used by the framework as there is no concept of a
+     BIGNUM_METHOD and they could not be generalised to the new
+     'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
+     ENGINE_cpy() has been removed as it cannot be consistently defined in
+     the new code.
+     [Geoff Thorpe]
+
+  *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
+     [Steve Henson]
+
+  *) Change mkdef.pl to sort symbols that get the same entry number,
+     and make sure the automatically generated functions ERR_load_*
+     become part of libeay.num as well.
+     [Richard Levitte]
+
+  *) New function SSL_renegotiate_pending().  This returns true once
+     renegotiation has been requested (either SSL_renegotiate() call
+     or HelloRequest/ClientHello received from the peer) and becomes
+     false once a handshake has been completed.
+     (For servers, SSL_renegotiate() followed by SSL_do_handshake()
+     sends a HelloRequest, but does not ensure that a handshake takes
+     place.  SSL_renegotiate_pending() is useful for checking if the
+     client has followed the request.)
+     [Bodo Moeller]
+
+  *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
+     By default, clients may request session resumption even during
+     renegotiation (if session ID contexts permit); with this option,
+     session resumption is possible only in the first handshake.
+
+     SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL.  This makes
+     more bits available for options that should not be part of
+     SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
+     [Bodo Moeller]
+
+  *) Add some demos for certificate and certificate request creation.
+     [Steve Henson]
+
+  *) Make maximum certificate chain size accepted from the peer application
+     settable (SSL*_get/set_max_cert_list()), as proposed by
+     "Douglas E. Engert" <deengert@anl.gov>.
+     [Lutz Jaenicke]
+
+  *) Add support for shared libraries for Unixware-7
+     (Boyd Lynn Gerber <gerberb@zenez.com>).
+     [Lutz Jaenicke]
+
+  *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
+     be done prior to destruction. Use this to unload error strings from
+     ENGINEs that load their own error strings. NB: This adds two new API
+     functions to "get" and "set" this destroy handler in an ENGINE.
+     [Geoff Thorpe]
+
+  *) Alter all existing ENGINE implementations (except "openssl" and
+     "openbsd") to dynamically instantiate their own error strings. This
+     makes them more flexible to be built both as statically-linked ENGINEs
+     and self-contained shared-libraries loadable via the "dynamic" ENGINE.
+     Also, add stub code to each that makes building them as self-contained
+     shared-libraries easier (see README.ENGINE).
+     [Geoff Thorpe]
+
+  *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
+     implementations into applications that are completely implemented in
+     self-contained shared-libraries. The "dynamic" ENGINE exposes control
+     commands that can be used to configure what shared-library to load and
+     to control aspects of the way it is handled. Also, made an update to
+     the README.ENGINE file that brings its information up-to-date and
+     provides some information and instructions on the "dynamic" ENGINE
+     (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
+     [Geoff Thorpe]
+
+  *) Make it possible to unload ranges of ERR strings with a new
+     "ERR_unload_strings" function.
+     [Geoff Thorpe]
+
+  *) Add a copy() function to EVP_MD.
+     [Ben Laurie]
+
+  *) Make EVP_MD routines take a context pointer instead of just the
+     md_data void pointer.
+     [Ben Laurie]
+
+  *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
+     that the digest can only process a single chunk of data
+     (typically because it is provided by a piece of
+     hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
+     is only going to provide a single chunk of data, and hence the
+     framework needn't accumulate the data for oneshot drivers.
+     [Ben Laurie]
+
+  *) As with "ERR", make it possible to replace the underlying "ex_data"
+     functions. This change also alters the storage and management of global
+     ex_data state - it's now all inside ex_data.c and all "class" code (eg.
+     RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
+     index counters. The API functions that use this state have been changed
+     to take a "class_index" rather than pointers to the class's local STACK
+     and counter, and there is now an API function to dynamically create new
+     classes. This centralisation allows us to (a) plug a lot of the
+     thread-safety problems that existed, and (b) makes it possible to clean
+     up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
+     such data would previously have always leaked in application code and
+     workarounds were in place to make the memory debugging turn a blind eye
+     to it. Application code that doesn't use this new function will still
+     leak as before, but their memory debugging output will announce it now
+     rather than letting it slide.
+
+     Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
+     induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
+     has a return value to indicate success or failure.
+     [Geoff Thorpe]
+
+  *) Make it possible to replace the underlying "ERR" functions such that the
+     global state (2 LHASH tables and 2 locks) is only used by the "default"
+     implementation. This change also adds two functions to "get" and "set"
+     the implementation prior to it being automatically set the first time
+     any other ERR function takes place. Ie. an application can call "get",
+     pass the return value to a module it has just loaded, and that module
+     can call its own "set" function using that value. This means the
+     module's "ERR" operations will use (and modify) the error state in the
+     application and not in its own statically linked copy of OpenSSL code.
+     [Geoff Thorpe]
+
+  *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
+     reference counts. This performs normal REF_PRINT/REF_CHECK macros on
+     the operation, and provides a more encapsulated way for external code
+     (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
+     to use these functions rather than manually incrementing the counts.
+
+     Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
+     [Geoff Thorpe]
+
+  *) Add EVP test program.
+     [Ben Laurie]
+
+  *) Add symmetric cipher support to ENGINE. Expect the API to change!
+     [Ben Laurie]
+
+  *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
+     X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
+     X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
+     These allow a CRL to be built without having to access X509_CRL fields
+     directly. Modify 'ca' application to use new functions.
+     [Steve Henson]
+
+  *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
+     bug workarounds. Rollback attack detection is a security feature.
+     The problem will only arise on OpenSSL servers when TLSv1 is not
+     available (sslv3_server_method() or SSL_OP_NO_TLSv1).
+     Software authors not wanting to support TLSv1 will have special reasons
+     for their choice and can explicitly enable this option.
+     [Bodo Moeller, Lutz Jaenicke]
+
+  *) Rationalise EVP so it can be extended: don't include a union of
+     cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
+     (similar to those existing for EVP_CIPHER_CTX).
+     Usage example:
+
+         EVP_MD_CTX md;
+
+         EVP_MD_CTX_init(&md);             /* new function call */
+         EVP_DigestInit(&md, EVP_sha1());
+         EVP_DigestUpdate(&md, in, len);
+         EVP_DigestFinal(&md, out, NULL);
+         EVP_MD_CTX_cleanup(&md);          /* new function call */
+
+     [Ben Laurie]
+
+  *) Make DES key schedule conform to the usual scheme, as well as
+     correcting its structure. This means that calls to DES functions
+     now have to pass a pointer to a des_key_schedule instead of a
+     plain des_key_schedule (which was actually always a pointer
+     anyway): E.g.,
+
+         des_key_schedule ks;
+
+	 des_set_key_checked(..., &ks);
+	 des_ncbc_encrypt(..., &ks, ...);
+
+     (Note that a later change renames 'des_...' into 'DES_...'.)
+     [Ben Laurie]
+
+  *) Initial reduction of linker bloat: the use of some functions, such as
+     PEM causes large amounts of unused functions to be linked in due to
+     poor organisation. For example pem_all.c contains every PEM function
+     which has a knock on effect of linking in large amounts of (unused)
+     ASN1 code. Grouping together similar functions and splitting unrelated
+     functions prevents this.
+     [Steve Henson]
+
+  *) Cleanup of EVP macros.
+     [Ben Laurie]
+
+  *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
+     correct _ecb suffix.
+     [Ben Laurie]
+
+  *) Add initial OCSP responder support to ocsp application. The
+     revocation information is handled using the text based index
+     use by the ca application. The responder can either handle
+     requests generated internally, supplied in files (for example
+     via a CGI script) or using an internal minimal server.
+     [Steve Henson]
+
+  *) Add configuration choices to get zlib compression for TLS.
+     [Richard Levitte]
+
+  *) Changes to Kerberos SSL for RFC 2712 compliance:
+     1.  Implemented real KerberosWrapper, instead of just using
+         KRB5 AP_REQ message.  [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
+     2.  Implemented optional authenticator field of KerberosWrapper.
+
+     Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
+     and authenticator structs; see crypto/krb5/.
+
+     Generalized Kerberos calls to support multiple Kerberos libraries.
+     [Vern Staats <staatsvr@asc.hpc.mil>,
+      Jeffrey Altman <jaltman@columbia.edu>
+      via Richard Levitte]
+
+  *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
+     already does with RSA. testdsa.h now has 'priv_key/pub_key'
+     values for each of the key sizes rather than having just
+     parameters (and 'speed' generating keys each time).
+     [Geoff Thorpe]

+
+  *) Added the OS2-EMX target.
+     ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
+
+  *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
+     to support NCONF routines in extension code. New function CONF_set_nconf()
+     to allow functions which take an NCONF to also handle the old LHASH
+     structure: this means that the old CONF compatible routines can be
+     retained (in particular wrt extensions) without having to duplicate the
+     code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
+     [Steve Henson]
+
+  *) Enhance the general user interface with mechanisms for inner control
+     and with possibilities to have yes/no kind of prompts.
+     [Richard Levitte]
+
+  *) Change all calls to low level digest routines in the library and
+     applications to use EVP. Add missing calls to HMAC_cleanup() and
+     don't assume HMAC_CTX can be copied using memcpy().
+     [Verdon Walker <VWalker@novell.com>, Steve Henson]
+
+  *) Add the possibility to control engines through control names but with
+     arbitrary arguments instead of just a string.
+     Change the key loaders to take a UI_METHOD instead of a callback
+     function pointer.  NOTE: this breaks binary compatibility with earlier
+     versions of OpenSSL [engine].
+     Adapt the nCipher code for these new conditions and add a card insertion
+     callback.
+     [Richard Levitte]
+
+  *) Enhance the general user interface with mechanisms to better support
+     dialog box interfaces, application-defined prompts, the possibility
+     to use defaults (for example default passwords from somewhere else)
+     and interrupts/cancellations.
+     [Richard Levitte]
+
+  *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
+     attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
+     [Steve Henson]
+
+  *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
+     tidy up some unnecessarily weird code in 'sk_new()').
+     [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
+
+  *) Change the key loading routines for ENGINEs to use the same kind
+     callback (pem_password_cb) as all other routines that need this
+     kind of callback.
+     [Richard Levitte]
+
+  *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
+     256 bit (=32 byte) keys. Of course seeding with more entropy bytes
+     than this minimum value is recommended.
+     [Lutz Jaenicke]
+
+  *) New random seeder for OpenVMS, using the system process statistics
+     that are easily reachable.
+     [Richard Levitte]
+
+  *) Windows apparently can't transparently handle global
+     variables defined in DLLs. Initialisations such as:
+
+        const ASN1_ITEM *it = &ASN1_INTEGER_it;
+
+     won't compile. This is used by the any applications that need to
+     declare their own ASN1 modules. This was fixed by adding the option
+     EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
+     needed for static libraries under Win32.
+     [Steve Henson]
+
+  *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
+     setting of purpose and trust fields. New X509_STORE trust and
+     purpose functions and tidy up setting in other SSL functions.
+     [Steve Henson]
+
+  *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
+     structure. These are inherited by X509_STORE_CTX when it is 
+     initialised. This allows various defaults to be set in the
+     X509_STORE structure (such as flags for CRL checking and custom
+     purpose or trust settings) for functions which only use X509_STORE_CTX
+     internally such as S/MIME.
+
+     Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
+     trust settings if they are not set in X509_STORE. This allows X509_STORE
+     purposes and trust (in S/MIME for example) to override any set by default.
+
+     Add command line options for CRL checking to smime, s_client and s_server
+     applications.
+     [Steve Henson]
+
+  *) Initial CRL based revocation checking. If the CRL checking flag(s)
+     are set then the CRL is looked up in the X509_STORE structure and
+     its validity and signature checked, then if the certificate is found
+     in the CRL the verify fails with a revoked error.
+
+     Various new CRL related callbacks added to X509_STORE_CTX structure.
+
+     Command line options added to 'verify' application to support this.
+
+     This needs some additional work, such as being able to handle multiple
+     CRLs with different times, extension based lookup (rather than just
+     by subject name) and ultimately more complete V2 CRL extension
+     handling.
+     [Steve Henson]
+
+  *) Add a general user interface API (crypto/ui/).  This is designed
+     to replace things like des_read_password and friends (backward
+     compatibility functions using this new API are provided).
+     The purpose is to remove prompting functions from the DES code
+     section as well as provide for prompting through dialog boxes in
+     a window system and the like.
+     [Richard Levitte]
+
+  *) Add "ex_data" support to ENGINE so implementations can add state at a
+     per-structure level rather than having to store it globally.
+     [Geoff]
+
+  *) Make it possible for ENGINE structures to be copied when retrieved by
+     ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
+     This causes the "original" ENGINE structure to act like a template,
+     analogous to the RSA vs. RSA_METHOD type of separation. Because of this
+     operational state can be localised to each ENGINE structure, despite the
+     fact they all share the same "methods". New ENGINE structures returned in
+     this case have no functional references and the return value is the single
+     structural reference. This matches the single structural reference returned
+     by ENGINE_by_id() normally, when it is incremented on the pre-existing
+     ENGINE structure.
+     [Geoff]
+
+  *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
+     needs to match any other type at all we need to manually clear the
+     tag cache.
+     [Steve Henson]
+
+  *) Changes to the "openssl engine" utility to include;
+     - verbosity levels ('-v', '-vv', and '-vvv') that provide information
+       about an ENGINE's available control commands.
+     - executing control commands from command line arguments using the
+       '-pre' and '-post' switches. '-post' is only used if '-t' is
+       specified and the ENGINE is successfully initialised. The syntax for
+       the individual commands are colon-separated, for example;
+	 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
+     [Geoff]
+
+  *) New dynamic control command support for ENGINEs. ENGINEs can now
+     declare their own commands (numbers), names (strings), descriptions,
+     and input types for run-time discovery by calling applications. A
+     subset of these commands are implicitly classed as "executable"
+     depending on their input type, and only these can be invoked through
+     the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
+     can be based on user input, config files, etc). The distinction is
+     that "executable" commands cannot return anything other than a boolean
+     result and can only support numeric or string input, whereas some
+     discoverable commands may only be for direct use through
+     ENGINE_ctrl(), eg. supporting the exchange of binary data, function
+     pointers, or other custom uses. The "executable" commands are to
+     support parameterisations of ENGINE behaviour that can be
+     unambiguously defined by ENGINEs and used consistently across any
+     OpenSSL-based application. Commands have been added to all the
+     existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
+     control over shared-library paths without source code alterations.
+     [Geoff]
+
+  *) Changed all ENGINE implementations to dynamically allocate their
+     ENGINEs rather than declaring them statically. Apart from this being
+     necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
+     this also allows the implementations to compile without using the
+     internal engine_int.h header.
+     [Geoff]
+
+  *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
+     'const' value. Any code that should be able to modify a RAND_METHOD
+     should already have non-const pointers to it (ie. they should only
+     modify their own ones).
+     [Geoff]
+
+  *) Made a variety of little tweaks to the ENGINE code.
+     - "atalla" and "ubsec" string definitions were moved from header files
+       to C code. "nuron" string definitions were placed in variables
+       rather than hard-coded - allowing parameterisation of these values
+       later on via ctrl() commands.
+     - Removed unused "#if 0"'d code.
+     - Fixed engine list iteration code so it uses ENGINE_free() to release
+       structural references.
+     - Constified the RAND_METHOD element of ENGINE structures.
+     - Constified various get/set functions as appropriate and added
+       missing functions (including a catch-all ENGINE_cpy that duplicates
+       all ENGINE values onto a new ENGINE except reference counts/state).
+     - Removed NULL parameter checks in get/set functions. Setting a method
+       or function to NULL is a way of cancelling out a previously set
+       value.  Passing a NULL ENGINE parameter is just plain stupid anyway
+       and doesn't justify the extra error symbols and code.
+     - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
+       flags from engine_int.h to engine.h.
+     - Changed prototypes for ENGINE handler functions (init(), finish(),
+       ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.

+
+  *) Implement binary inversion algorithm for BN_mod_inverse in addition
+     to the algorithm using long division.  The binary algorithm can be
+     used only if the modulus is odd.  On 32-bit systems, it is faster
+     only for relatively small moduli (roughly 20-30% for 128-bit moduli,
+     roughly 5-15% for 256-bit moduli), so we use it only for moduli
+     up to 450 bits.  In 64-bit environments, the binary algorithm
+     appears to be advantageous for much longer moduli; here we use it
+     for moduli up to 2048 bits.
+     [Bodo Moeller]
+
+  *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
+     could not support the combine flag in choice fields.
+     [Steve Henson]
+
+  *) Add a 'copy_extensions' option to the 'ca' utility. This copies
+     extensions from a certificate request to the certificate.
+     [Steve Henson]
+
+  *) Allow multiple 'certopt' and 'nameopt' options to be separated
+     by commas. Add 'namopt' and 'certopt' options to the 'ca' config
+     file: this allows the display of the certificate about to be
+     signed to be customised, to allow certain fields to be included
+     or excluded and extension details. The old system didn't display
+     multicharacter strings properly, omitted fields not in the policy
+     and couldn't display additional details such as extensions.
+     [Steve Henson]
+
+  *) Function EC_POINTs_mul for multiple scalar multiplication
+     of an arbitrary number of elliptic curve points
+          \sum scalars[i]*points[i],
+     optionally including the generator defined for the EC_GROUP:
+          scalar*generator +  \sum scalars[i]*points[i].
+
+     EC_POINT_mul is a simple wrapper function for the typical case
+     that the point list has just one item (besides the optional
+     generator).
+     [Bodo Moeller]
+
+  *) First EC_METHODs for curves over GF(p):
+
+     EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
+     operations and provides various method functions that can also
+     operate with faster implementations of modular arithmetic.     
+
+     EC_GFp_mont_method() reuses most functions that are part of
+     EC_GFp_simple_method, but uses Montgomery arithmetic.
+
+     [Bodo Moeller; point addition and point doubling
+     implementation directly derived from source code provided by
+     Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
+
+  *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
+     crypto/ec/ec_lib.c):
+
+     Curves are EC_GROUP objects (with an optional group generator)
+     based on EC_METHODs that are built into the library.
+
+     Points are EC_POINT objects based on EC_GROUP objects.
+
+     Most of the framework would be able to handle curves over arbitrary
+     finite fields, but as there are no obvious types for fields other
+     than GF(p), some functions are limited to that for now.
+     [Bodo Moeller]
+
+  *) Add the -HTTP option to s_server.  It is similar to -WWW, but requires
+     that the file contains a complete HTTP response.
+     [Richard Levitte]
+
+  *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
+     change the def and num file printf format specifier from "%-40sXXX"
+     to "%-39s XXX". The latter will always guarantee a space after the
+     field while the former will cause them to run together if the field
+     is 40 of more characters long.
+     [Steve Henson]
+
+  *) Constify the cipher and digest 'method' functions and structures
+     and modify related functions to take constant EVP_MD and EVP_CIPHER
+     pointers.
+     [Steve Henson]
+
+  *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
+     in <openssl/bn.h>.  Also further increase BN_CTX_NUM to 32.
+     [Bodo Moeller]
+
+  *) Modify EVP_Digest*() routines so they now return values. Although the
+     internal software routines can never fail additional hardware versions
+     might.
+     [Steve Henson]
+
+  *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
+
+     Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
+     (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
+
+     ASN1 error codes
+          ERR_R_NESTED_ASN1_ERROR
+          ...
+          ERR_R_MISSING_ASN1_EOS
+     were 4 .. 9, conflicting with
+          ERR_LIB_RSA (= ERR_R_RSA_LIB)
+          ...
+          ERR_LIB_PEM (= ERR_R_PEM_LIB).
+     They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
+
+     Add new error code 'ERR_R_INTERNAL_ERROR'.
+     [Bodo Moeller]
+
+  *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
+     suffices.
+     [Bodo Moeller]
+
+  *) New option '-subj arg' for 'openssl req' and 'openssl ca'.  This
+     sets the subject name for a new request or supersedes the
+     subject name in a given request. Formats that can be parsed are
+          'CN=Some Name, OU=myOU, C=IT'
+     and
+          'CN=Some Name/OU=myOU/C=IT'.
+
+     Add options '-batch' and '-verbose' to 'openssl req'.
+     [Massimiliano Pala <madwolf@hackmasters.net>]
+
+  *) Introduce the possibility to access global variables through
+     functions on platform were that's the best way to handle exporting
+     global variables in shared libraries.  To enable this functionality,
+     one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
+     "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
+     is normally done by Configure or something similar).
+
+     To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
+     in the source file (foo.c) like this:
+
+	OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
+	OPENSSL_IMPLEMENT_GLOBAL(double,bar);
+
+     To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
+     and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
+
+	OPENSSL_DECLARE_GLOBAL(int,foo);
+	#define foo OPENSSL_GLOBAL_REF(foo)
+	OPENSSL_DECLARE_GLOBAL(double,bar);
+	#define bar OPENSSL_GLOBAL_REF(bar)
+
+     The #defines are very important, and therefore so is including the
+     header file everywhere where the defined globals are used.
+
+     The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
+     of ASN.1 items, but that structure is a bit different.
+
+     The largest change is in util/mkdef.pl which has been enhanced with
+     better and easier to understand logic to choose which symbols should
+     go into the Windows .def files as well as a number of fixes and code
+     cleanup (among others, algorithm keywords are now sorted
+     lexicographically to avoid constant rewrites).
+     [Richard Levitte]
+
+  *) In BN_div() keep a copy of the sign of 'num' before writing the
+     result to 'rm' because if rm==num the value will be overwritten
+     and produce the wrong result if 'num' is negative: this caused
+     problems with BN_mod() and BN_nnmod().
+     [Steve Henson]
+
+  *) Function OCSP_request_verify(). This checks the signature on an
+     OCSP request and verifies the signer certificate. The signer
+     certificate is just checked for a generic purpose and OCSP request
+     trust settings.
+     [Steve Henson]
+
+  *) Add OCSP_check_validity() function to check the validity of OCSP
+     responses. OCSP responses are prepared in real time and may only
+     be a few seconds old. Simply checking that the current time lies
+     between thisUpdate and nextUpdate max reject otherwise valid responses
+     caused by either OCSP responder or client clock inaccuracy. Instead
+     we allow thisUpdate and nextUpdate to fall within a certain period of
+     the current time. The age of the response can also optionally be
+     checked. Two new options -validity_period and -status_age added to
+     ocsp utility.
+     [Steve Henson]
+
+  *) If signature or public key algorithm is unrecognized print out its
+     OID rather that just UNKNOWN.
+     [Steve Henson]
+
+  *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
+     OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
+     ID to be generated from the issuer certificate alone which can then be
+     passed to OCSP_id_issuer_cmp().
+     [Steve Henson]
+
+  *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
+     ASN1 modules to export functions returning ASN1_ITEM pointers
+     instead of the ASN1_ITEM structures themselves. This adds several
+     new macros which allow the underlying ASN1 function/structure to
+     be accessed transparently. As a result code should not use ASN1_ITEM
+     references directly (such as &X509_it) but instead use the relevant
+     macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
+     use of the new ASN1 code on platforms where exporting structures
+     is problematical (for example in shared libraries) but exporting
+     functions returning pointers to structures is not.
+     [Steve Henson]
+
+  *) Add support for overriding the generation of SSL/TLS session IDs.
+     These callbacks can be registered either in an SSL_CTX or per SSL.
+     The purpose of this is to allow applications to control, if they wish,
+     the arbitrary values chosen for use as session IDs, particularly as it
+     can be useful for session caching in multiple-server environments. A
+     command-line switch for testing this (and any client code that wishes
+     to use such a feature) has been added to "s_server".
+     [Geoff Thorpe, Lutz Jaenicke]
+
+  *) Modify mkdef.pl to recognise and parse preprocessor conditionals
+     of the form '#if defined(...) || defined(...) || ...' and
+     '#if !defined(...) && !defined(...) && ...'.  This also avoids
+     the growing number of special cases it was previously handling.
+     [Richard Levitte]
+
+  *) Make all configuration macros available for application by making
+     sure they are available in opensslconf.h, by giving them names starting
+     with "OPENSSL_" to avoid conflicts with other packages and by making
+     sure e_os2.h will cover all platform-specific cases together with
+     opensslconf.h.
+     Additionally, it is now possible to define configuration/platform-
+     specific names (called "system identities").  In the C code, these
+     are prefixed with "OPENSSL_SYSNAME_".  e_os2.h will create another
+     macro with the name beginning with "OPENSSL_SYS_", which is determined
+     from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
+     what is available.
+     [Richard Levitte]
+
+  *) New option -set_serial to 'req' and 'x509' this allows the serial
+     number to use to be specified on the command line. Previously self
+     signed certificates were hard coded with serial number 0 and the 
+     CA options of 'x509' had to use a serial number in a file which was
+     auto incremented.
+     [Steve Henson]
+
+  *) New options to 'ca' utility to support V2 CRL entry extensions.
+     Currently CRL reason, invalidity date and hold instruction are
+     supported. Add new CRL extensions to V3 code and some new objects.
+     [Steve Henson]
+
+  *) New function EVP_CIPHER_CTX_set_padding() this is used to
+     disable standard block padding (aka PKCS#5 padding) in the EVP
+     API, which was previously mandatory. This means that the data is
+     not padded in any way and so the total length much be a multiple
+     of the block size, otherwise an error occurs.
+     [Steve Henson]
+
+  *) Initial (incomplete) OCSP SSL support.
+     [Steve Henson]
+
+  *) New function OCSP_parse_url(). This splits up a URL into its host,
+     port and path components: primarily to parse OCSP URLs. New -url
+     option to ocsp utility.
+     [Steve Henson]
+
+  *) New nonce behavior. The return value of OCSP_check_nonce() now 
+     reflects the various checks performed. Applications can decide
+     whether to tolerate certain situations such as an absent nonce
+     in a response when one was present in a request: the ocsp application
+     just prints out a warning. New function OCSP_add1_basic_nonce()
+     this is to allow responders to include a nonce in a response even if
+     the request is nonce-less.
+     [Steve Henson]
+
+  *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
+     skipped when using openssl x509 multiple times on a single input file,
+     e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
+     [Bodo Moeller]
+
+  *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
+     set string type: to handle setting ASN1_TIME structures. Fix ca
+     utility to correctly initialize revocation date of CRLs.
+     [Steve Henson]
+
+  *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
+     the clients preferred ciphersuites and rather use its own preferences.
+     Should help to work around M$ SGC (Server Gated Cryptography) bug in
+     Internet Explorer by ensuring unchanged hash method during stepup.
+     (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
+     [Lutz Jaenicke]
+
+  *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
+     to aes and add a new 'exist' option to print out symbols that don't
+     appear to exist.
+     [Steve Henson]
+
+  *) Additional options to ocsp utility to allow flags to be set and
+     additional certificates supplied.
+     [Steve Henson]
+
+  *) Add the option -VAfile to 'openssl ocsp', so the user can give the
+     OCSP client a number of certificate to only verify the response
+     signature against.
+     [Richard Levitte]
+
+  *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
+     handle the new API. Currently only ECB, CBC modes supported. Add new
+     AES OIDs.
+
+     Add TLS AES ciphersuites as described in RFC3268, "Advanced
+     Encryption Standard (AES) Ciphersuites for Transport Layer
+     Security (TLS)".  (In beta versions of OpenSSL 0.9.7, these were
+     not enabled by default and were not part of the "ALL" ciphersuite
+     alias because they were not yet official; they could be
+     explicitly requested by specifying the "AESdraft" ciphersuite
+     group alias.  In the final release of OpenSSL 0.9.7, the group
+     alias is called "AES" and is part of "ALL".)
+     [Ben Laurie, Steve  Henson, Bodo Moeller]
+
+  *) New function OCSP_copy_nonce() to copy nonce value (if present) from
+     request to response.
+     [Steve Henson]
+
+  *) Functions for OCSP responders. OCSP_request_onereq_count(),
+     OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
+     extract information from a certificate request. OCSP_response_create()
+     creates a response and optionally adds a basic response structure.
+     OCSP_basic_add1_status() adds a complete single response to a basic
+     response and returns the OCSP_SINGLERESP structure just added (to allow
+     extensions to be included for example). OCSP_basic_add1_cert() adds a
+     certificate to a basic response and OCSP_basic_sign() signs a basic
+     response with various flags. New helper functions ASN1_TIME_check()
+     (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
+     (converts ASN1_TIME to GeneralizedTime).
+     [Steve Henson]
+
+  *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
+     in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
+     structure from a certificate. X509_pubkey_digest() digests the public_key
+     contents: this is used in various key identifiers. 
+     [Steve Henson]
+
+  *) Make sk_sort() tolerate a NULL argument.
+     [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
+     passed by the function are trusted implicitly. If any of them signed the
+     response then it is assumed to be valid and is not verified.
+     [Steve Henson]
+
+  *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
+     to data. This was previously part of the PKCS7 ASN1 code. This
+     was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
+     [Steve Henson, reported by Kenneth R. Robinette
+				<support@securenetterm.com>]
+
+  *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
+     routines: without these tracing memory leaks is very painful.
+     Fix leaks in PKCS12 and PKCS7 routines.
+     [Steve Henson]
+
+  *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
+     Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
+     effectively meant GeneralizedTime would never be used. Now it
+     is initialised to -1 but X509_time_adj() now has to check the value
+     and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
+     V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
+     [Steve Henson, reported by Kenneth R. Robinette
+				<support@securenetterm.com>]
+
+  *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
+     result in a zero length in the ASN1_INTEGER structure which was
+     not consistent with the structure when d2i_ASN1_INTEGER() was used
+     and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
+     to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
+     where it did not print out a minus for negative ASN1_INTEGER.
+     [Steve Henson]
+
+  *) Add summary printout to ocsp utility. The various functions which
+     convert status values to strings have been renamed to:
+     OCSP_response_status_str(), OCSP_cert_status_str() and
+     OCSP_crl_reason_str() and are no longer static. New options
+     to verify nonce values and to disable verification. OCSP response
+     printout format cleaned up.
+     [Steve Henson]
+
+  *) Add additional OCSP certificate checks. These are those specified
+     in RFC2560. This consists of two separate checks: the CA of the
+     certificate being checked must either be the OCSP signer certificate
+     or the issuer of the OCSP signer certificate. In the latter case the
+     OCSP signer certificate must contain the OCSP signing extended key
+     usage. This check is performed by attempting to match the OCSP
+     signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
+     in the OCSP_CERTID structures of the response.
+     [Steve Henson]
+
+  *) Initial OCSP certificate verification added to OCSP_basic_verify()
+     and related routines. This uses the standard OpenSSL certificate
+     verify routines to perform initial checks (just CA validity) and
+     to obtain the certificate chain. Then additional checks will be
+     performed on the chain. Currently the root CA is checked to see
+     if it is explicitly trusted for OCSP signing. This is used to set
+     a root CA as a global signing root: that is any certificate that
+     chains to that CA is an acceptable OCSP signing certificate.
+     [Steve Henson]
+
+  *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
+     extensions from a separate configuration file.
+     As when reading extensions from the main configuration file,
+     the '-extensions ...' option may be used for specifying the
+     section to use.
+     [Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) New OCSP utility. Allows OCSP requests to be generated or
+     read. The request can be sent to a responder and the output
+     parsed, outputed or printed in text form. Not complete yet:
+     still needs to check the OCSP response validity.
+     [Steve Henson]
+
+  *) New subcommands for 'openssl ca':
+     'openssl ca -status <serial>' prints the status of the cert with
+     the given serial number (according to the index file).
+     'openssl ca -updatedb' updates the expiry status of certificates
+     in the index file.
+     [Massimiliano Pala <madwolf@comune.modena.it>]
+
+  *) New '-newreq-nodes' command option to CA.pl.  This is like
+     '-newreq', but calls 'openssl req' with the '-nodes' option
+     so that the resulting key is not encrypted.
+     [Damien Miller <djm@mindrot.org>]
+
+  *) New configuration for the GNU Hurd.
+     [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
+
+  *) Initial code to implement OCSP basic response verify. This
+     is currently incomplete. Currently just finds the signer's
+     certificate and verifies the signature on the response.
+     [Steve Henson]
+
+  *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
+     value of OPENSSLDIR.  This is available via the new '-d' option
+     to 'openssl version', and is also included in 'openssl version -a'.
+     [Bodo Moeller]
+
+  *) Allowing defining memory allocation callbacks that will be given
+     file name and line number information in additional arguments
+     (a const char* and an int).  The basic functionality remains, as
+     well as the original possibility to just replace malloc(),
+     realloc() and free() by functions that do not know about these
+     additional arguments.  To register and find out the current
+     settings for extended allocation functions, the following
+     functions are provided:
+
+	CRYPTO_set_mem_ex_functions
+	CRYPTO_set_locked_mem_ex_functions
+	CRYPTO_get_mem_ex_functions
+	CRYPTO_get_locked_mem_ex_functions
+
+     These work the same way as CRYPTO_set_mem_functions and friends.
+     CRYPTO_get_[locked_]mem_functions now writes 0 where such an
+     extended allocation function is enabled.
+     Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
+     a conventional allocation function is enabled.
+     [Richard Levitte, Bodo Moeller]
+
+  *) Finish off removing the remaining LHASH function pointer casts.
+     There should no longer be any prototype-casting required when using
+     the LHASH abstraction, and any casts that remain are "bugs". See
+     the callback types and macros at the head of lhash.h for details
+     (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
+     [Geoff Thorpe]
+
+  *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
+     If /dev/[u]random devices are not available or do not return enough
+     entropy, EGD style sockets (served by EGD or PRNGD) will automatically
+     be queried.
+     The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
+     /etc/entropy will be queried once each in this sequence, querying stops
+     when enough entropy was collected without querying more sockets.
+     [Lutz Jaenicke]
+
+  *) Change the Unix RAND_poll() variant to be able to poll several
+     random devices, as specified by DEVRANDOM, until a sufficient amount
+     of data has been collected.   We spend at most 10 ms on each file
+     (select timeout) and read in non-blocking mode.  DEVRANDOM now
+     defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
+     (previously it was just the string "/dev/urandom"), so on typical
+     platforms the 10 ms delay will never occur.
+     Also separate out the Unix variant to its own file, rand_unix.c.
+     For VMS, there's a currently-empty rand_vms.c.
+     [Richard Levitte]
+
+  *) Move OCSP client related routines to ocsp_cl.c. These
+     provide utility functions which an application needing
+     to issue a request to an OCSP responder and analyse the
+     response will typically need: as opposed to those which an
+     OCSP responder itself would need which will be added later.
+
+     OCSP_request_sign() signs an OCSP request with an API similar
+     to PKCS7_sign(). OCSP_response_status() returns status of OCSP
+     response. OCSP_response_get1_basic() extracts basic response
+     from response. OCSP_resp_find_status(): finds and extracts status
+     information from an OCSP_CERTID structure (which will be created
+     when the request structure is built). These are built from lower
+     level functions which work on OCSP_SINGLERESP structures but
+     won't normally be used unless the application wishes to examine
+     extensions in the OCSP response for example.
+
+     Replace nonce routines with a pair of functions.
+     OCSP_request_add1_nonce() adds a nonce value and optionally
+     generates a random value. OCSP_check_nonce() checks the
+     validity of the nonce in an OCSP response.
+     [Steve Henson]
+
+  *) Change function OCSP_request_add() to OCSP_request_add0_id().
+     This doesn't copy the supplied OCSP_CERTID and avoids the
+     need to free up the newly created id. Change return type
+     to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
+     This can then be used to add extensions to the request.
+     Deleted OCSP_request_new(), since most of its functionality
+     is now in OCSP_REQUEST_new() (and the case insensitive name
+     clash) apart from the ability to set the request name which
+     will be added elsewhere.
+     [Steve Henson]
+
+  *) Update OCSP API. Remove obsolete extensions argument from
+     various functions. Extensions are now handled using the new
+     OCSP extension code. New simple OCSP HTTP function which 
+     can be used to send requests and parse the response.
+     [Steve Henson]
+
+  *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
+     ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
+     uses the special reorder version of SET OF to sort the attributes
+     and reorder them to match the encoded order. This resolves a long
+     standing problem: a verify on a PKCS7 structure just after signing
+     it used to fail because the attribute order did not match the
+     encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
+     it uses the received order. This is necessary to tolerate some broken
+     software that does not order SET OF. This is handled by encoding
+     as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
+     to produce the required SET OF.
+     [Steve Henson]
+
+  *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
+     OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
+     files to get correct declarations of the ASN.1 item variables.
+     [Richard Levitte]
+
+  *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
+     PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
+     asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
+     NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
+     New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
+     ASN1_ITEM and no wrapper functions.
+     [Steve Henson]
+
+  *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
+     replace the old function pointer based I/O routines. Change most of
+     the *_d2i_bio() and *_d2i_fp() functions to use these.
+     [Steve Henson]
+
+  *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
+     lines, recognice more "algorithms" that can be deselected, and make
+     it complain about algorithm deselection that isn't recognised.
+     [Richard Levitte]
+
+  *) New ASN1 functions to handle dup, sign, verify, digest, pack and
+     unpack operations in terms of ASN1_ITEM. Modify existing wrappers
+     to use new functions. Add NO_ASN1_OLD which can be set to remove
+     some old style ASN1 functions: this can be used to determine if old
+     code will still work when these eventually go away.
+     [Steve Henson]
+
+  *) New extension functions for OCSP structures, these follow the
+     same conventions as certificates and CRLs.
+     [Steve Henson]
+
+  *) New function X509V3_add1_i2d(). This automatically encodes and
+     adds an extension. Its behaviour can be customised with various
+     flags to append, replace or delete. Various wrappers added for
+     certificates and CRLs.
+     [Steve Henson]
+
+  *) Fix to avoid calling the underlying ASN1 print routine when
+     an extension cannot be parsed. Correct a typo in the
+     OCSP_SERVICELOC extension. Tidy up print OCSP format.
+     [Steve Henson]
+
+  *) Make mkdef.pl parse some of the ASN1 macros and add appropriate
+     entries for variables.
+     [Steve Henson]
+
+  *) Add functionality to apps/openssl.c for detecting locking
+     problems: As the program is single-threaded, all we have
+     to do is register a locking callback using an array for
+     storing which locks are currently held by the program.
+     [Bodo Moeller]
+
+  *) Use a lock around the call to CRYPTO_get_ex_new_index() in
+     SSL_get_ex_data_X509_STORE_idx(), which is used in
+     ssl_verify_cert_chain() and thus can be called at any time
+     during TLS/SSL handshakes so that thread-safety is essential.
+     Unfortunately, the ex_data design is not at all suited
+     for multi-threaded use, so it probably should be abolished.
+     [Bodo Moeller]
+
+  *) Added Broadcom "ubsec" ENGINE to OpenSSL.
+     [Broadcom, tweaked and integrated by Geoff Thorpe]
+
+  *) Move common extension printing code to new function
+     X509V3_print_extensions(). Reorganise OCSP print routines and
+     implement some needed OCSP ASN1 functions. Add OCSP extensions.
+     [Steve Henson]
+
+  *) New function X509_signature_print() to remove duplication in some
+     print routines.
+     [Steve Henson]
+
+  *) Add a special meaning when SET OF and SEQUENCE OF flags are both
+     set (this was treated exactly the same as SET OF previously). This
+     is used to reorder the STACK representing the structure to match the
+     encoding. This will be used to get round a problem where a PKCS7
+     structure which was signed could not be verified because the STACK
+     order did not reflect the encoded order.
+     [Steve Henson]
+
+  *) Reimplement the OCSP ASN1 module using the new code.
+     [Steve Henson]
+
+  *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
+     for its ASN1 operations. The old style function pointers still exist
+     for now but they will eventually go away.
+     [Steve Henson]
+
+  *) Merge in replacement ASN1 code from the ASN1 branch. This almost
+     completely replaces the old ASN1 functionality with a table driven
+     encoder and decoder which interprets an ASN1_ITEM structure describing
+     the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
+     largely maintained. Almost all of the old asn1_mac.h macro based ASN1
+     has also been converted to the new form.
+     [Steve Henson]
+
+  *) Change BN_mod_exp_recp so that negative moduli are tolerated
+     (the sign is ignored).  Similarly, ignore the sign in BN_MONT_CTX_set
+     so that BN_mod_exp_mont and BN_mod_exp_mont_word work
+     for negative moduli.
+     [Bodo Moeller]
+
+  *) Fix BN_uadd and BN_usub: Always return non-negative results instead
+     of not touching the result's sign bit.
+     [Bodo Moeller]
+
+  *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
+     set.
+     [Bodo Moeller]
+
+  *) Changed the LHASH code to use prototypes for callbacks, and created
+     macros to declare and implement thin (optionally static) functions
+     that provide type-safety and avoid function pointer casting for the
+     type-specific callbacks.
+     [Geoff Thorpe]
+
+  *) Added Kerberos Cipher Suites to be used with TLS, as written in
+     RFC 2712.
+     [Veers Staats <staatsvr@asc.hpc.mil>,
+      Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
+
+  *) Reformat the FAQ so the different questions and answers can be divided
+     in sections depending on the subject.
+     [Richard Levitte]
+
+  *) Have the zlib compression code load ZLIB.DLL dynamically under
+     Windows.
+     [Richard Levitte]
+
+  *) New function BN_mod_sqrt for computing square roots modulo a prime
+     (using the probabilistic Tonelli-Shanks algorithm unless
+     p == 3 (mod 4)  or  p == 5 (mod 8),  which are cases that can
+     be handled deterministically).
+     [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
+
+  *) Make BN_mod_inverse faster by explicitly handling small quotients
+     in the Euclid loop. (Speed gain about 20% for small moduli [256 or
+     512 bits], about 30% for larger ones [1024 or 2048 bits].)
+     [Bodo Moeller]
+
+  *) New function BN_kronecker.
+     [Bodo Moeller]
+
+  *) Fix BN_gcd so that it works on negative inputs; the result is
+     positive unless both parameters are zero.
+     Previously something reasonably close to an infinite loop was
+     possible because numbers could be growing instead of shrinking
+     in the implementation of Euclid's algorithm.
+     [Bodo Moeller]
+
+  *) Fix BN_is_word() and BN_is_one() macros to take into account the
+     sign of the number in question.
+
+     Fix BN_is_word(a,w) to work correctly for w == 0.
+
+     The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
+     because its test if the absolute value of 'a' equals 'w'.
+     Note that BN_abs_is_word does *not* handle w == 0 reliably;
+     it exists mostly for use in the implementations of BN_is_zero(),
+     BN_is_one(), and BN_is_word().
+     [Bodo Moeller]
+
+  *) New function BN_swap.
+     [Bodo Moeller]
+
+  *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
+     the exponentiation functions are more likely to produce reasonable
+     results on negative inputs.
+     [Bodo Moeller]
+
+  *) Change BN_mod_mul so that the result is always non-negative.
+     Previously, it could be negative if one of the factors was negative;
+     I don't think anyone really wanted that behaviour.
+     [Bodo Moeller]
+
+  *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
+     (except for exponentiation, which stays in crypto/bn/bn_exp.c,
+     and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
+     and add new functions:
+
+          BN_nnmod
+          BN_mod_sqr
+          BN_mod_add
+          BN_mod_add_quick
+          BN_mod_sub
+          BN_mod_sub_quick
+          BN_mod_lshift1
+          BN_mod_lshift1_quick
+          BN_mod_lshift
+          BN_mod_lshift_quick
+
+     These functions always generate non-negative results.
+
+     BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder  r
+     such that  |m| < r < 0,  BN_nnmod will output  rem + |m|  instead).
+
+     BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
+     BN_mod_XXX(r, a, [b,] m, ctx), but requires that  a  [and  b]
+     be reduced modulo  m.

+     The following entry accidentally appeared in the CHANGES file
+     distributed with OpenSSL 0.9.7.  The modifications described in
+     it do *not* apply to OpenSSL 0.9.7.
+
+  *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
+     was actually never needed) and in BN_mul().  The removal in BN_mul()
+     required a small change in bn_mul_part_recursive() and the addition
+     of the functions bn_cmp_part_words(), bn_sub_part_words() and
+     bn_add_part_words(), which do the same thing as bn_cmp_words(),
+     bn_sub_words() and bn_add_words() except they take arrays with
+     differing sizes.
+     [Richard Levitte]
+#endif
+
+  *) In 'openssl passwd', verify passwords read from the terminal
+     unless the '-salt' option is used (which usually means that
+     verification would just waste user's time since the resulting
+     hash is going to be compared with some given password hash)
+     or the new '-noverify' option is used.
+
+     This is an incompatible change, but it does not affect
+     non-interactive use of 'openssl passwd' (passwords on the command
+     line, '-stdin' option, '-in ...' option) and thus should not
+     cause any problems.
+     [Bodo Moeller]
+
+  *) Remove all references to RSAref, since there's no more need for it.
+     [Richard Levitte]
+
+  *) Make DSO load along a path given through an environment variable
+     (SHLIB_PATH) with shl_load().
+     [Richard Levitte]
+
+  *) Constify the ENGINE code as a result of BIGNUM constification.
+     Also constify the RSA code and most things related to it.  In a
+     few places, most notable in the depth of the ASN.1 code, ugly
+     casts back to non-const were required (to be solved at a later
+     time)
+     [Richard Levitte]
+
+  *) Make it so the openssl application has all engines loaded by default.
+     [Richard Levitte]
+
+  *) Constify the BIGNUM routines a little more.
+     [Richard Levitte]
+
+  *) Add the following functions:
+
+	ENGINE_load_cswift()
+	ENGINE_load_chil()
+	ENGINE_load_atalla()
+	ENGINE_load_nuron()
+	ENGINE_load_builtin_engines()
+
+     That way, an application can itself choose if external engines that
+     are built-in in OpenSSL shall ever be used or not.  The benefit is
+     that applications won't have to be linked with libdl or other dso
+     libraries unless it's really needed.
+
+     Changed 'openssl engine' to load all engines on demand.
+     Changed the engine header files to avoid the duplication of some
+     declarations (they differed!).
+     [Richard Levitte]
+
+  *) 'openssl engine' can now list capabilities.
+     [Richard Levitte]
+
+  *) Better error reporting in 'openssl engine'.
+     [Richard Levitte]
+
+  *) Never call load_dh_param(NULL) in s_server.
+     [Bodo Moeller]
+
+  *) Add engine application.  It can currently list engines by name and
+     identity, and test if they are actually available.
+     [Richard Levitte]
+
+  *) Improve RPM specification file by forcing symbolic linking and making
+     sure the installed documentation is also owned by root.root.
+     [Damien Miller <djm@mindrot.org>]
+
+  *) Give the OpenSSL applications more possibilities to make use of
+     keys (public as well as private) handled by engines.
+     [Richard Levitte]
+
+  *) Add OCSP code that comes from CertCo.
+     [Richard Levitte]
+
+  *) Add VMS support for the Rijndael code.
+     [Richard Levitte]
+
+  *) Added untested support for Nuron crypto accelerator.
+     [Ben Laurie]
+
+  *) Add support for external cryptographic devices.  This code was
+     previously distributed separately as the "engine" branch.
+     [Geoff Thorpe, Richard Levitte]
+
+  *) Rework the filename-translation in the DSO code. It is now possible to
+     have far greater control over how a "name" is turned into a filename
+     depending on the operating environment and any oddities about the
+     different shared library filenames on each system.
+     [Geoff Thorpe]
+
+  *) Support threads on FreeBSD-elf in Configure.
+     [Richard Levitte]
+
+  *) Fix for SHA1 assembly problem with MASM: it produces
+     warnings about corrupt line number information when assembling
+     with debugging information. This is caused by the overlapping
+     of two sections.
+     [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
+
+  *) NCONF changes.
+     NCONF_get_number() has no error checking at all.  As a replacement,
+     NCONF_get_number_e() is defined (_e for "error checking") and is
+     promoted strongly.  The old NCONF_get_number is kept around for
+     binary backward compatibility.
+     Make it possible for methods to load from something other than a BIO,
+     by providing a function pointer that is given a name instead of a BIO.
+     For example, this could be used to load configuration data from an
+     LDAP server.
+     [Richard Levitte]
+
+  *) Fix for non blocking accept BIOs. Added new I/O special reason
+     BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
+     with non blocking I/O was not possible because no retry code was
+     implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
+     this case.
+     [Steve Henson]
+
+  *) Added the beginnings of Rijndael support.
+     [Ben Laurie]
+
+  *) Fix for bug in DirectoryString mask setting. Add support for
+     X509_NAME_print_ex() in 'req' and X509_print_ex() function
+     to allow certificate printing to more controllable, additional
+     'certopt' option to 'x509' to allow new printing options to be

+     specifications.
+     [Steve Henson]
+
+  *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
+     extra data after the compression methods not only for TLS 1.0
+     but also for SSL 3.0 (as required by the specification).
+     [Bodo Moeller; problem pointed out by Matthias Loepfe]

+     [Bodo Moeller]
+
+  *) Turn on RSA blinding by default in the default implementation
+     to avoid a timing attack. Applications that don't want it can call
+     RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
+     They would be ill-advised to do so in most cases.
+     [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
+
+  *) Change RSA blinding code so that it works when the PRNG is not
+     seeded (in this case, the secret RSA exponent is abused as
+     an unpredictable seed -- if it is not unpredictable, there
+     is no point in blinding anyway).  Make RSA blinding thread-safe
+     by remembering the creator's thread ID in rsa->blinding and
+     having all other threads use local one-time blinding factors
+     (this requires more computation than sharing rsa->blinding, but
+     avoids excessive locking; and if an RSA object is not shared
+     between threads, blinding will still be very fast).

+
+ Changes between 0.9.6h and 0.9.6i  [19 Feb 2003]
+
+  *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
+     via timing by performing a MAC computation even if incorrrect
+     block cipher padding has been found.  This is a countermeasure
+     against active attacks where the attacker has to distinguish
+     between bad padding and a MAC verification error. (CVE-2003-0078)

+
+ Changes between 0.9.6g and 0.9.6h  [5 Dec 2002]
+
+  *) New function OPENSSL_cleanse(), which is used to cleanse a section of
+     memory from it's contents.  This is done with a counter that will
+     place alternating values in each byte.  This can be used to solve
+     two issues: 1) the removal of calls to memset() by highly optimizing
+     compilers, and 2) cleansing with other values than 0, since those can
+     be read through on certain media, for example a swap space on disk.
+     [Geoff Thorpe]
+
+  *) Bugfix: client side session caching did not work with external caching,
+     because the session->cipher setting was not restored when reloading
+     from the external cache. This problem was masked, when
+     SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.

+     [Zeev Lieber <zeev-l@yahoo.com>]
+

+     the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
+     doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
+     the bitwise-OR of the two for use by the majority of applications
+     wanting this behaviour, and update the docs. The documented
+     behaviour and actual behaviour were inconsistent and had been

+
+     In the new general case, we do not insist that 'generator' is

+
+  *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of

+
+  *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()

+     not contain client_version: Instead of aborting with an error,
+     simply choose the highest available protocol version (i.e.,
+     TLS 1.0 unless it is disabled).  In practice, ClientHello
+     messages are never sent like this, but this change gives us
+     strictly correct behaviour at least for TLS.
+     [Bodo Moeller]

+     [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
+
+  *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
+     should end in 'break', not 'goto end' which circumvents various
+     cleanups done in state SSL_ST_OK.   But session related stuff
+     must be disabled for SSL_ST_OK in the case that we just sent a

+
+     Also avoid some overhead by not calling ssl_init_wbio_buffer()
+     before just sending a HelloRequest.
+     [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
+
+  *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't

+     verification error occurred.  (Neither SSLerr() codes nor alerts
+     are directly visible to potential attackers, but the information
+     may leak via logfiles.)
+
+     Similar changes are not required for the SSL 2.0 implementation
+     because the number of padding bytes is sent in clear for SSL 2.0,
+     and the extra bytes are just ignored.  However ssl/s2_pkt.c
+     failed to verify that the purported number of padding bytes is in
+     the legal range.

+
+  *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
+     dh->length and always used
+
+          BN_rand_range(priv_key, dh->p).
+
+     BN_rand_range() is not necessary for Diffie-Hellman, and this
+     specific range makes Diffie-Hellman unnecessarily inefficient if
+     dh->length (recommended exponent length) is much smaller than the
+     length of dh->p.  We could use BN_rand_range() if the order of

+
+     So switch back to

+

+     to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
+     Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
+     PRNG state recovery was possible based on the output of
+     one PRNG request appropriately sized to gain knowledge on
+     'md' followed by enough consecutive 1-byte PRNG requests
+     to traverse all of 'state'.
+
+     1. When updating 'md_local' (the current thread's copy of 'md')
+        during PRNG output generation, hash all of the previous
+        'md_local' value, not just the half used for PRNG output.
+
+     2. Make the number of bytes from 'state' included into the hash
+        independent from the number of PRNG bytes requested.
+
+     The first measure alone would be sufficient to avoid
+     Markku-Juhani's attack.  (Actually it had never occurred
+     to me that the half of 'md_local' used for chaining was the
+     half from which PRNG output bytes were taken -- I had always
+     assumed that the secret half would be used.)  The second
+     measure makes sure that additional data from 'state' is never
+     mixed into 'md_local' in small portions; this heuristically
+     further strengthens the PRNG.

+
+  *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
+     RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
+     when fixing the server behaviour for backwards-compatible 'client
+     hello' messages.  (Note that the attack is impractical against
+     SSL 3.0 and TLS 1.0 anyway because length and version checking
+     means that the probability of guessing a valid ciphertext is
+     around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
+     paper.)
+
+     Before 0.9.5, the countermeasure (hide the error by generating a
+     random 'decryption result') did not work properly because
+     ERR_clear_error() was missing, meaning that SSL_get_error() would
+     detect the supposedly ignored error.
+
+     Both problems are now fixed.
+     [Bodo Moeller]
+
+  *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096

+     [Steve Henson]
+
+  *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
+     in the current directory if neither $RANDFILE nor $HOME was set.
+     RAND_file_name() in 0.9.6a returned NULL in this case.  This has
+     caused some confusion to Windows users who haven't defined $HOME.
+     Thus RAND_file_name() is changed again: e_os.h can define a
+     DEFAULT_HOME, which will be used if $HOME is not set.
+     For Windows, we use "C:"; on other platforms, we still require
+     environment variables.
+
+  *) Move 'if (!initialized) RAND_poll()' into regions protected by

+     [Bodo Moeller]
+
+  *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a

+     Otherwise while one thread is in ssleay_rand_bytes (which sets the
+     flag), *other* threads can enter ssleay_add_bytes without obeying
+     the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
+     that they do not hold after the first thread unsets add_do_not_lock).

+     [Bodo Moeller]
+
+  *) Fix SSL_peek:
+     Both ssl2_peek and ssl3_peek, which were totally broken in earlier
+     releases, have been re-implemented by renaming the previous
+     implementations of ssl2_read and ssl3_read to ssl2_read_internal
+     and ssl3_read_internal, respectively, and adding 'peek' parameters
+     to them.  The new ssl[23]_{read,peek} functions are calls to
+     ssl[23]_read_internal with the 'peek' flag set appropriately.
+     A 'peek' parameter has also been added to ssl3_read_bytes, which

+
+     - Make as few rebuilds of the shared libraries as possible.

+
+     Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
+     and not in SSL_clear because the latter is also used by the

+
+  *) In ssl23_get_client_hello, generate an error message when faced
+     with an initial SSL 3.0/TLS record that is too small to contain the
+     first two bytes of the ClientHello message, i.e. client_version.
+     (Note that this is a pathologic case that probably has never happened
+     in real life.)  The previous approach was to use the version number
+     from the record header as a substitute; but our protocol choice
+     should not depend on that one because it is not authenticated
+     by the Finished messages.
+     [Bodo Moeller]
+
+  *) More robust randomness gathering functions for Windows.
+     [Jeffrey Altman <jaltman@columbia.edu>]
+
+  *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
+     not set then we don't setup the error code for issuer check errors
+     to avoid possibly overwriting other errors which the callback does
+     handle. If an application does set the flag then we assume it knows
+     what it is doing and can handle the new informational codes
+     appropriately.
+     [Steve Henson]
+
+  *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
+     a general "ANY" type, as such it should be able to decode anything
+     including tagged types. However it didn't check the class so it would
+     wrongly interpret tagged types in the same way as their universal
+     counterpart and unknown types were just rejected. Changed so that the
+     tagged and unknown types are handled in the same way as a SEQUENCE:
+     that is the encoding is stored intact. There is also a new type
+     "V_ASN1_OTHER" which is used when the class is not universal, in this
+     case we have no idea what the actual type is so we just lump them all
+     together.
+     [Steve Henson]
+
+  *) On VMS, stdout may very well lead to a file that is written to
+     in a record-oriented fashion.  That means that every write() will
+     write a separate record, which will be read separately by the
+     programs trying to read from it.  This can be very confusing.
+
+     The solution is to put a BIO filter in the way that will buffer
+     text until a linefeed is reached, and then write everything a
+     line at a time, so every record written will be an actual line,
+     not chunks of lines and not (usually doesn't happen, but I've
+     seen it once) several lines in one record.  BIO_f_linebuffer() is
+     the answer.
+
+     Currently, it's a VMS-only method, because that's where it has
+     been tested well enough.
+     [Richard Levitte]
+
+  *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
+     it can return incorrect results.
+     (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
+     but it was in 0.9.6-beta[12].)
+     [Bodo Moeller]
+
+  *) Disable the check for content being present when verifying detached
+     signatures in pk7_smime.c. Some versions of Netscape (wrongly)
+     include zero length content when signing messages.
+     [Steve Henson]
+
+  *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR

+
+  *) Bug fix: Montgomery multiplication could produce results with the
+     wrong sign.
+     [Ulf Möller]
+
+  *) Add RPM specification openssl.spec and modify it to build three
+     packages.  The default package contains applications, application
+     documentation and run-time libraries.  The devel package contains
+     include files, static libraries and function documentation.  The
+     doc package contains the contents of the doc directory.  The original
+     openssl.spec was provided by Damien Miller <djm@mindrot.org>.
+     [Richard Levitte]

+
+  *) Don't set the two most significant bits to one when generating a
+     random number < q in the DSA library.
+     [Ulf Möller]
+
+  *) New SSL API mode 'SSL_MODE_AUTO_RETRY'.  This disables the default
+     behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
+     the underlying transport is blocking) if a handshake took place.
+     (The default behaviour is needed by applications such as s_client
+     and s_server that use select() to determine when to use SSL_read;
+     but for applications that know in advance when to expect data, it
+     just makes things more complicated.)
+     [Bodo Moeller]
+
+  *) Add RAND_egd_bytes(), which gives control over the number of bytes read
+     from EGD.
+     [Ben Laurie]
+
+  *) Add a few more EBCDIC conditionals that make `req' and `x509'
+     work better on such systems.
+     [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
+
+  *) Add two demo programs for PKCS12_parse() and PKCS12_create().
+     Update PKCS12_parse() so it copies the friendlyName and the
+     keyid to the certificates aux info.
+     [Steve Henson]
+
+  *) Fix bug in PKCS7_verify() which caused an infinite loop
+     if there was more than one signature.
+     [Sven Uszpelkat <su@celocom.de>]
+
+  *) Major change in util/mkdef.pl to include extra information
+     about each symbol, as well as presenting variables as well
+     as functions.  This change means that there's n more need
+     to rebuild the .num files when some algorithms are excluded.
+     [Richard Levitte]
+
+  *) Allow the verify time to be set by an application,
+     rather than always using the current time.
+     [Steve Henson]
+  
+  *) Phase 2 verify code reorganisation. The certificate
+     verify code now looks up an issuer certificate by a
+     number of criteria: subject name, authority key id
+     and key usage. It also verifies self signed certificates
+     by the same criteria. The main comparison function is
+     X509_check_issued() which performs these checks.
+ 
+     Lot of changes were necessary in order to support this
+     without completely rewriting the lookup code.
+ 
+     Authority and subject key identifier are now cached.
+ 
+     The LHASH 'certs' is X509_STORE has now been replaced
+     by a STACK_OF(X509_OBJECT). This is mainly because an
+     LHASH can't store or retrieve multiple objects with
+     the same hash value.
+
+     As a result various functions (which were all internal
+     use only) have changed to handle the new X509_STORE
+     structure. This will break anything that messed round
+     with X509_STORE internally.
+ 
+     The functions X509_STORE_add_cert() now checks for an
+     exact match, rather than just subject name.
+ 
+     The X509_STORE API doesn't directly support the retrieval
+     of multiple certificates matching a given criteria, however
+     this can be worked round by performing a lookup first
+     (which will fill the cache with candidate certificates)
+     and then examining the cache for matches. This is probably
+     the best we can do without throwing out X509_LOOKUP
+     entirely (maybe later...).
+ 
+     The X509_VERIFY_CTX structure has been enhanced considerably.
+ 
+     All certificate lookup operations now go via a get_issuer()
+     callback. Although this currently uses an X509_STORE it
+     can be replaced by custom lookups. This is a simple way
+     to bypass the X509_STORE hackery necessary to make this
+     work and makes it possible to use more efficient techniques
+     in future. A very simple version which uses a simple
+     STACK for its trusted certificate store is also provided
+     using X509_STORE_CTX_trusted_stack().
+ 
+     The verify_cb() and verify() callbacks now have equivalents
+     in the X509_STORE_CTX structure.
+ 
+     X509_STORE_CTX also has a 'flags' field which can be used
+     to customise the verify behaviour.
+     [Steve Henson]
+ 
+  *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which 
+     excludes S/MIME capabilities.
+     [Steve Henson]
+
+  *) When a certificate request is read in keep a copy of the
+     original encoding of the signed data and use it when outputting
+     again. Signatures then use the original encoding rather than
+     a decoded, encoded version which may cause problems if the
+     request is improperly encoded.
+     [Steve Henson]
+
+  *) For consistency with other BIO_puts implementations, call
+     buffer_write(b, ...) directly in buffer_puts instead of calling
+     BIO_write(b, ...).
+
+     In BIO_puts, increment b->num_write as in BIO_write.
+     [Peter.Sylvester@EdelWeb.fr]
+
+  *) Fix BN_mul_word for the case where the word is 0. (We have to use
+     BN_zero, we may not return a BIGNUM with an array consisting of
+     words set to zero.)
+     [Bodo Moeller]
+
+  *) Avoid calling abort() from within the library when problems are
+     detected, except if preprocessor symbols have been defined
+     (such as REF_CHECK, BN_DEBUG etc.).
+     [Bodo Moeller]
+
+  *) New openssl application 'rsautl'. This utility can be
+     used for low level RSA operations. DER public key
+     BIO/fp routines also added.
+     [Steve Henson]
+
+  *) New Configure entry and patches for compiling on QNX 4.
+     [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
+
+  *) A demo state-machine implementation was sponsored by
+     Nuron (http://www.nuron.com/) and is now available in
+     demos/state_machine.
+     [Ben Laurie]
+
+  *) New options added to the 'dgst' utility for signature
+     generation and verification.
+     [Steve Henson]
+
+  *) Unrecognized PKCS#7 content types are now handled via a
+     catch all ASN1_TYPE structure. This allows unsupported
+     types to be stored as a "blob" and an application can
+     encode and decode it manually.
+     [Steve Henson]
+
+  *) Fix various signed/unsigned issues to make a_strex.c
+     compile under VC++.
+     [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
+
+  *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
+     length if passed a buffer. ASN1_INTEGER_to_BN failed
+     if passed a NULL BN and its argument was negative.
+     [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
+
+  *) Modification to PKCS#7 encoding routines to output definite
+     length encoding. Since currently the whole structures are in
+     memory there's not real point in using indefinite length 
+     constructed encoding. However if OpenSSL is compiled with
+     the flag PKCS7_INDEFINITE_ENCODING the old form is used.
+     [Steve Henson]
+
+  *) Added BIO_vprintf() and BIO_vsnprintf().
+     [Richard Levitte]
+
+  *) Added more prefixes to parse for in the the strings written
+     through a logging bio, to cover all the levels that are available
+     through syslog.  The prefixes are now:
+
+	PANIC, EMERG, EMR	=>	LOG_EMERG
+	ALERT, ALR		=>	LOG_ALERT
+	CRIT, CRI		=>	LOG_CRIT
+	ERROR, ERR		=>	LOG_ERR
+	WARNING, WARN, WAR	=>	LOG_WARNING
+	NOTICE, NOTE, NOT	=>	LOG_NOTICE
+	INFO, INF		=>	LOG_INFO
+	DEBUG, DBG		=>	LOG_DEBUG
+
+     and as before, if none of those prefixes are present at the
+     beginning of the string, LOG_ERR is chosen.
+
+     On Win32, the LOG_* levels are mapped according to this:
+
+	LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR	=> EVENTLOG_ERROR_TYPE
+	LOG_WARNING				=> EVENTLOG_WARNING_TYPE
+	LOG_NOTICE, LOG_INFO, LOG_DEBUG		=> EVENTLOG_INFORMATION_TYPE
+
+     [Richard Levitte]
+
+  *) Made it possible to reconfigure with just the configuration
+     argument "reconf" or "reconfigure".  The command line arguments
+     are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
+     and are retrieved from there when reconfiguring.
+     [Richard Levitte]
+
+  *) MD4 implemented.
+     [Assar Westerlund <assar@sics.se>, Richard Levitte]
+
+  *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
+     [Richard Levitte]
+
+  *) The obj_dat.pl script was messing up the sorting of object
+     names. The reason was that it compared the quoted version
+     of strings as a result "OCSP" > "OCSP Signing" because
+     " > SPACE. Changed script to store unquoted versions of
+     names and add quotes on output. It was also omitting some
+     names from the lookup table if they were given a default
+     value (that is if SN is missing it is given the same
+     value as LN and vice versa), these are now added on the
+     grounds that if an object has a name we should be able to
+     look it up. Finally added warning output when duplicate
+     short or long names are found.
+     [Steve Henson]
+
+  *) Changes needed for Tandem NSK.
+     [Scott Uroff <scott@xypro.com>]
+
+  *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
+     RSA_padding_check_SSLv23(), special padding was never detected
+     and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
+     version rollback attacks was not effective.
+
+     In s23_clnt.c, don't use special rollback-attack detection padding
+     (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
+     client; similarly, in s23_srvr.c, don't do the rollback check if
+     SSL 2.0 is the only protocol enabled in the server.
+     [Bodo Moeller]
+
+  *) Make it possible to get hexdumps of unprintable data with 'openssl
+     asn1parse'.  By implication, the functions ASN1_parse_dump() and
+     BIO_dump_indent() are added.
+     [Richard Levitte]
+
+  *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
+     these print out strings and name structures based on various
+     flags including RFC2253 support and proper handling of
+     multibyte characters. Added options to the 'x509' utility 
+     to allow the various flags to be set.
+     [Steve Henson]
+
+  *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
+     Also change the functions X509_cmp_current_time() and
+     X509_gmtime_adj() work with an ASN1_TIME structure,
+     this will enable certificates using GeneralizedTime in validity
+     dates to be checked.
+     [Steve Henson]
+
+  *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
+     negative public key encodings) on by default,
+     NO_NEG_PUBKEY_BUG can be set to disable it.
+     [Steve Henson]
+
+  *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
+     content octets. An i2c_ASN1_OBJECT is unnecessary because
+     the encoding can be trivially obtained from the structure.
+     [Steve Henson]
+
+  *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
+     not read locks (CRYPTO_r_[un]lock).
+     [Bodo Moeller]
+
+  *) A first attempt at creating official support for shared
+     libraries through configuration.  I've kept it so the
+     default is static libraries only, and the OpenSSL programs
+     are always statically linked for now, but there are
+     preparations for dynamic linking in place.
+     This has been tested on Linux and Tru64.
+     [Richard Levitte]
+
+  *) Randomness polling function for Win9x, as described in:
+     Peter Gutmann, Software Generation of Practically Strong
+     Random Numbers.
+     [Ulf Möller]
+
+  *) Fix so PRNG is seeded in req if using an already existing
+     DSA key.
+     [Steve Henson]
+
+  *) New options to smime application. -inform and -outform
+     allow alternative formats for the S/MIME message including
+     PEM and DER. The -content option allows the content to be
+     specified separately. This should allow things like Netscape
+     form signing output easier to verify.
+     [Steve Henson]
+
+  *) Fix the ASN1 encoding of tags using the 'long form'.
+     [Steve Henson]
+
+  *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
+     STRING types. These convert content octets to and from the
+     underlying type. The actual tag and length octets are
+     already assumed to have been read in and checked. These
+     are needed because all other string types have virtually
+     identical handling apart from the tag. By having versions
+     of the ASN1 functions that just operate on content octets
+     IMPLICIT tagging can be handled properly. It also allows
+     the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
+     and ASN1_INTEGER are identical apart from the tag.
+     [Steve Henson]
+
+  *) Change the handling of OID objects as follows:
+
+     - New object identifiers are inserted in objects.txt, following
+       the syntax given in objects.README.
+     - objects.pl is used to process obj_mac.num and create a new
+       obj_mac.h.
+     - obj_dat.pl is used to create a new obj_dat.h, using the data in
+       obj_mac.h.
+
+     This is currently kind of a hack, and the perl code in objects.pl
+     isn't very elegant, but it works as I intended.  The simplest way
+     to check that it worked correctly is to look in obj_dat.h and
+     check the array nid_objs and make sure the objects haven't moved
+     around (this is important!).  Additions are OK, as well as
+     consistent name changes. 
+     [Richard Levitte]
+
+  *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
+     [Bodo Moeller]
+
+  *) Addition of the command line parameter '-rand file' to 'openssl req'.
+     The given file adds to whatever has already been seeded into the
+     random pool through the RANDFILE configuration file option or
+     environment variable, or the default random state file.
+     [Richard Levitte]
+
+  *) mkstack.pl now sorts each macro group into lexical order.
+     Previously the output order depended on the order the files
+     appeared in the directory, resulting in needless rewriting
+     of safestack.h .
+     [Steve Henson]
+
+  *) Patches to make OpenSSL compile under Win32 again. Mostly
+     work arounds for the VC++ problem that it treats func() as
+     func(void). Also stripped out the parts of mkdef.pl that
+     added extra typesafe functions: these no longer exist.
+     [Steve Henson]
+
+  *) Reorganisation of the stack code. The macros are now all 
+     collected in safestack.h . Each macro is defined in terms of
+     a "stack macro" of the form SKM_<name>(type, a, b). The 
+     DEBUG_SAFESTACK is now handled in terms of function casts,
+     this has the advantage of retaining type safety without the
+     use of additional functions. If DEBUG_SAFESTACK is not defined
+     then the non typesafe macros are used instead. Also modified the
+     mkstack.pl script to handle the new form. Needs testing to see
+     if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
+     the default if no major problems. Similar behaviour for ASN1_SET_OF
+     and PKCS12_STACK_OF.
+     [Steve Henson]
+
+  *) When some versions of IIS use the 'NET' form of private key the
+     key derivation algorithm is different. Normally MD5(password) is
+     used as a 128 bit RC4 key. In the modified case
+     MD5(MD5(password) + "SGCKEYSALT")  is used instead. Added some
+     new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
+     as the old Netscape_RSA functions except they have an additional
+     'sgckey' parameter which uses the modified algorithm. Also added
+     an -sgckey command line option to the rsa utility. Thanks to 
+     Adrian Peck <bertie@ncipher.com> for posting details of the modified
+     algorithm to openssl-dev.
+     [Steve Henson]
+
+  *) The evp_local.h macros were using 'c.##kname' which resulted in
+     invalid expansion on some systems (SCO 5.0.5 for example).
+     Corrected to 'c.kname'.
+     [Phillip Porch <root@theporch.com>]
+
+  *) New X509_get1_email() and X509_REQ_get1_email() functions that return
+     a STACK of email addresses from a certificate or request, these look
+     in the subject name and the subject alternative name extensions and 
+     omit any duplicate addresses.
+     [Steve Henson]
+
+  *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
+     This makes DSA verification about 2 % faster.
+     [Bodo Moeller]
+
+  *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
+     (meaning that now 2^5 values will be precomputed, which is only 4 KB
+     plus overhead for 1024 bit moduli).
+     This makes exponentiations about 0.5 % faster for 1024 bit
+     exponents (as measured by "openssl speed rsa2048").
+     [Bodo Moeller]
+
+  *) Rename memory handling macros to avoid conflicts with other
+     software:
+          Malloc         =>  OPENSSL_malloc
+          Malloc_locked  =>  OPENSSL_malloc_locked
+          Realloc        =>  OPENSSL_realloc
+          Free           =>  OPENSSL_free
+     [Richard Levitte]
+
+  *) New function BN_mod_exp_mont_word for small bases (roughly 15%
+     faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
+     [Bodo Moeller]
+
+  *) CygWin32 support.
+     [John Jarvie <jjarvie@newsguy.com>]
+
+  *) The type-safe stack code has been rejigged. It is now only compiled
+     in when OpenSSL is configured with the DEBUG_SAFESTACK option and
+     by default all type-specific stack functions are "#define"d back to
+     standard stack functions. This results in more streamlined output
+     but retains the type-safety checking possibilities of the original
+     approach.
+     [Geoff Thorpe]
+
+  *) The STACK code has been cleaned up, and certain type declarations
+     that didn't make a lot of sense have been brought in line. This has
+     also involved a cleanup of sorts in safestack.h to more correctly
+     map type-safe stack functions onto their plain stack counterparts.
+     This work has also resulted in a variety of "const"ifications of
+     lots of the code, especially "_cmp" operations which should normally
+     be prototyped with "const" parameters anyway.
+     [Geoff Thorpe]
+
+  *) When generating bytes for the first time in md_rand.c, 'stir the pool'
+     by seeding with STATE_SIZE dummy bytes (with zero entropy count).
+     (The PRNG state consists of two parts, the large pool 'state' and 'md',
+     where all of 'md' is used each time the PRNG is used, but 'state'
+     is used only indexed by a cyclic counter. As entropy may not be
+     well distributed from the beginning, 'md' is important as a
+     chaining variable. However, the output function chains only half
+     of 'md', i.e. 80 bits.  ssleay_rand_add, on the other hand, chains
+     all of 'md', and seeding with STATE_SIZE dummy bytes will result
+     in all of 'state' being rewritten, with the new values depending
+     on virtually all of 'md'.  This overcomes the 80 bit limitation.)
+     [Bodo Moeller]
+
+  *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
+     the handshake is continued after ssl_verify_cert_chain();
+     otherwise, if SSL_VERIFY_NONE is set, remaining error codes
+     can lead to 'unexplainable' connection aborts later.
+     [Bodo Moeller; problem tracked down by Lutz Jaenicke]
+
+  *) Major EVP API cipher revision.
+     Add hooks for extra EVP features. This allows various cipher
+     parameters to be set in the EVP interface. Support added for variable
+     key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
+     setting of RC2 and RC5 parameters.
+
+     Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
+     ciphers.
+
+     Remove lots of duplicated code from the EVP library. For example *every*
+     cipher init() function handles the 'iv' in the same way according to the
+     cipher mode. They also all do nothing if the 'key' parameter is NULL and
+     for CFB and OFB modes they zero ctx->num.
+
+     New functionality allows removal of S/MIME code RC2 hack.
+
+     Most of the routines have the same form and so can be declared in terms
+     of macros.
+
+     By shifting this to the top level EVP_CipherInit() it can be removed from
+     all individual ciphers. If the cipher wants to handle IVs or keys
+     differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
+     flags.
+
+     Change lots of functions like EVP_EncryptUpdate() to now return a
+     value: although software versions of the algorithms cannot fail
+     any installed hardware versions can.
+     [Steve Henson]
+
+  *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
+     this option is set, tolerate broken clients that send the negotiated
+     protocol version number instead of the requested protocol version
+     number.
+     [Bodo Moeller]
+
+  *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
+     i.e. non-zero for export ciphersuites, zero otherwise.
+     Previous versions had this flag inverted, inconsistent with
+     rsa_tmp_cb (..._TMP_RSA_CB).
+     [Bodo Moeller; problem reported by Amit Chopra]
+
+  *) Add missing DSA library text string. Work around for some IIS
+     key files with invalid SEQUENCE encoding.
+     [Steve Henson]
+
+  *) Add a document (doc/standards.txt) that list all kinds of standards
+     and so on that are implemented in OpenSSL.
+     [Richard Levitte]
+
+  *) Enhance c_rehash script. Old version would mishandle certificates
+     with the same subject name hash and wouldn't handle CRLs at all.
+     Added -fingerprint option to crl utility, to support new c_rehash
+     features.
+     [Steve Henson]
+
+  *) Eliminate non-ANSI declarations in crypto.h and stack.h.
+     [Ulf Möller]
+
+  *) Fix for SSL server purpose checking. Server checking was
+     rejecting certificates which had extended key usage present
+     but no ssl client purpose.
+     [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
+
+  *) Make PKCS#12 code work with no password. The PKCS#12 spec
+     is a little unclear about how a blank password is handled.
+     Since the password in encoded as a BMPString with terminating
+     double NULL a zero length password would end up as just the
+     double NULL. However no password at all is different and is
+     handled differently in the PKCS#12 key generation code. NS
+     treats a blank password as zero length. MSIE treats it as no
+     password on export: but it will try both on import. We now do
+     the same: PKCS12_parse() tries zero length and no password if
+     the password is set to "" or NULL (NULL is now a valid password:
+     it wasn't before) as does the pkcs12 application.
+     [Steve Henson]
+
+  *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
+     perror when PEM_read_bio_X509_REQ fails, the error message must
+     be obtained from the error queue.
+     [Bodo Moeller]
+
+  *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
+     it in ERR_remove_state if appropriate, and change ERR_get_state
+     accordingly to avoid race conditions (this is necessary because
+     thread_hash is no longer constant once set).
+     [Bodo Moeller]
+
+  *) Bugfix for linux-elf makefile.one.
+     [Ulf Möller]
+
+  *) RSA_get_default_method() will now cause a default
+     RSA_METHOD to be chosen if one doesn't exist already.
+     Previously this was only set during a call to RSA_new()
+     or RSA_new_method(NULL) meaning it was possible for
+     RSA_get_default_method() to return NULL.
+     [Geoff Thorpe]
+
+  *) Added native name translation to the existing DSO code
+     that will convert (if the flag to do so is set) filenames
+     that are sufficiently small and have no path information
+     into a canonical native form. Eg. "blah" converted to
+     "libblah.so" or "blah.dll" etc.
+     [Geoff Thorpe]
+
+  *) New function ERR_error_string_n(e, buf, len) which is like
+     ERR_error_string(e, buf), but writes at most 'len' bytes
+     including the 0 terminator.  For ERR_error_string_n, 'buf'
+     may not be NULL.
+     [Damien Miller <djm@mindrot.org>, Bodo Moeller]
+
+  *) CONF library reworked to become more general.  A new CONF
+     configuration file reader "class" is implemented as well as a
+     new functions (NCONF_*, for "New CONF") to handle it.  The now
+     old CONF_* functions are still there, but are reimplemented to
+     work in terms of the new functions.  Also, a set of functions
+     to handle the internal storage of the configuration data is
+     provided to make it easier to write new configuration file
+     reader "classes" (I can definitely see something reading a
+     configuration file in XML format, for example), called _CONF_*,
+     or "the configuration storage API"...
+
+     The new configuration file reading functions are:
+
+        NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
+        NCONF_get_section, NCONF_get_string, NCONF_get_numbre
+
+        NCONF_default, NCONF_WIN32
+
+        NCONF_dump_fp, NCONF_dump_bio
+
+     NCONF_default and NCONF_WIN32 are method (or "class") choosers,
+     NCONF_new creates a new CONF object.  This works in the same way
+     as other interfaces in OpenSSL, like the BIO interface.
+     NCONF_dump_* dump the internal storage of the configuration file,
+     which is useful for debugging.  All other functions take the same
+     arguments as the old CONF_* functions wth the exception of the
+     first that must be a `CONF *' instead of a `LHASH *'.
+
+     To make it easer to use the new classes with the old CONF_* functions,
+     the function CONF_set_default_method is provided.
+     [Richard Levitte]
+
+  *) Add '-tls1' option to 'openssl ciphers', which was already
+     mentioned in the documentation but had not been implemented.
+     (This option is not yet really useful because even the additional
+     experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
+     [Bodo Moeller]
+
+  *) Initial DSO code added into libcrypto for letting OpenSSL (and
+     OpenSSL-based applications) load shared libraries and bind to
+     them in a portable way.
+     [Geoff Thorpe, with contributions from Richard Levitte]
+
+ Changes between 0.9.5 and 0.9.5a  [1 Apr 2000]
+
+  *) Make sure _lrotl and _lrotr are only used with MSVC.
+
+  *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
+     (the default implementation of RAND_status).
+
+  *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
+     to '-clrext' (= clear extensions), as intended and documented.
+     [Bodo Moeller; inconsistency pointed out by Michael Attili
+     <attili@amaxo.com>]
+
+  *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
+     was larger than the MD block size.      
+     [Steve Henson, pointed out by Yost William <YostW@tce.com>]
+
+  *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
+     fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
+     using the passed key: if the passed key was a private key the result
+     of X509_print(), for example, would be to print out all the private key
+     components.
+     [Steve Henson]
+
+  *) des_quad_cksum() byte order bug fix.
+     [Ulf Möller, using the problem description in krb4-0.9.7, where
+      the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
+
+  *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
+     discouraged.
+     [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
+
+  *) For easily testing in shell scripts whether some command
+     'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
+     returns with exit code 0 iff no command of the given name is available.
+     'no-XXX' is printed in this case, 'XXX' otherwise.  In both cases,
+     the output goes to stdout and nothing is printed to stderr.
+     Additional arguments are always ignored.
+
+     Since for each cipher there is a command of the same name,
+     the 'no-cipher' compilation switches can be tested this way.
+
+     ('openssl no-XXX' is not able to detect pseudo-commands such
+     as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
+     [Bodo Moeller]
+
+  *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
+     [Bodo Moeller]
+
+  *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
+     is set; it will be thrown away anyway because each handshake creates
+     its own key.
+     ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
+     to parameters -- in previous versions (since OpenSSL 0.9.3) the
+     'default key' from SSL_CTX_set_tmp_dh would always be lost, meaning
+     you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
+     [Bodo Moeller]
+
+  *) New s_client option -ign_eof: EOF at stdin is ignored, and
+     'Q' and 'R' lose their special meanings (quit/renegotiate).
+     This is part of what -quiet does; unlike -quiet, -ign_eof
+     does not suppress any output.
+     [Richard Levitte]
+
+  *) Add compatibility options to the purpose and trust code. The
+     purpose X509_PURPOSE_ANY is "any purpose" which automatically
+     accepts a certificate or CA, this was the previous behaviour,
+     with all the associated security issues.
+
+     X509_TRUST_COMPAT is the old trust behaviour: only and
+     automatically trust self signed roots in certificate store. A
+     new trust setting X509_TRUST_DEFAULT is used to specify that
+     a purpose has no associated trust setting and it should instead
+     use the value in the default purpose.
+     [Steve Henson]
+
+  *) Fix the PKCS#8 DSA private key code so it decodes keys again
+     and fix a memory leak.
+     [Steve Henson]
+
+  *) In util/mkerr.pl (which implements 'make errors'), preserve
+     reason strings from the previous version of the .c file, as
+     the default to have only downcase letters (and digits) in
+     automatically generated reasons codes is not always appropriate.
+     [Bodo Moeller]
+
+  *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
+     using strerror.  Previously, ERR_reason_error_string() returned
+     library names as reason strings for SYSerr; but SYSerr is a special
+     case where small numbers are errno values, not library numbers.
+     [Bodo Moeller]
+
+  *) Add '-dsaparam' option to 'openssl dhparam' application.  This
+     converts DSA parameters into DH parameters. (When creating parameters,
+     DSA_generate_parameters is used.)
+     [Bodo Moeller]
+
+  *) Include 'length' (recommended exponent length) in C code generated
+     by 'openssl dhparam -C'.
+     [Bodo Moeller]
+
+  *) The second argument to set_label in perlasm was already being used
+     so couldn't be used as a "file scope" flag. Moved to third argument
+     which was free.
+     [Steve Henson]
+
+  *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
+     instead of RAND_bytes for encryption IVs and salts.
+     [Bodo Moeller]
+
+  *) Include RAND_status() into RAND_METHOD instead of implementing
+     it only for md_rand.c  Otherwise replacing the PRNG by calling
+     RAND_set_rand_method would be impossible.
+     [Bodo Moeller]
+
+  *) Don't let DSA_generate_key() enter an infinite loop if the random
+     number generation fails.
+     [Bodo Moeller]
+
+  *) New 'rand' application for creating pseudo-random output.
+     [Bodo Moeller]
+
+  *) Added configuration support for Linux/IA64
+     [Rolf Haberrecker <rolf@suse.de>]
+
+  *) Assembler module support for Mingw32.
+     [Ulf Möller]
+
+  *) Shared library support for HPUX (in shlib/).
+     [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
+
+  *) Shared library support for Solaris gcc.
+     [Lutz Behnke <behnke@trustcenter.de>]
+
+ Changes between 0.9.4 and 0.9.5  [28 Feb 2000]
+
+  *) PKCS7_encrypt() was adding text MIME headers twice because they
+     were added manually and by SMIME_crlf_copy().
+     [Steve Henson]
+
+  *) In bntest.c don't call BN_rand with zero bits argument.
+     [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
+
+  *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
+     case was implemented. This caused BN_div_recp() to fail occasionally.
+     [Ulf Möller]
+
+  *) Add an optional second argument to the set_label() in the perl
+     assembly language builder. If this argument exists and is set
+     to 1 it signals that the assembler should use a symbol whose 
+     scope is the entire file, not just the current function. This
+     is needed with MASM which uses the format label:: for this scope.
+     [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
+
+  *) Change the ASN1 types so they are typedefs by default. Before
+     almost all types were #define'd to ASN1_STRING which was causing
+     STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
+     for example.
+     [Steve Henson]
+
+  *) Change names of new functions to the new get1/get0 naming
+     convention: After 'get1', the caller owns a reference count
+     and has to call ..._free; 'get0' returns a pointer to some
+     data structure without incrementing reference counters.
+     (Some of the existing 'get' functions increment a reference
+     counter, some don't.)
+     Similarly, 'set1' and 'add1' functions increase reference
+     counters or duplicate objects.
+     [Steve Henson]
+
+  *) Allow for the possibility of temp RSA key generation failure:
+     the code used to assume it always worked and crashed on failure.
+     [Steve Henson]
+
+  *) Fix potential buffer overrun problem in BIO_printf().
+     [Ulf Möller, using public domain code by Patrick Powell; problem
+      pointed out by David Sacerdote <das33@cornell.edu>]
+
+  *) Support EGD <http://www.lothar.com/tech/crypto/>.  New functions
+     RAND_egd() and RAND_status().  In the command line application,
+     the EGD socket can be specified like a seed file using RANDFILE
+     or -rand.
+     [Ulf Möller]
+
+  *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
+     Some CAs (e.g. Verisign) distribute certificates in this form.
+     [Steve Henson]
+
+  *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
+     list to exclude them. This means that no special compilation option
+     is needed to use anonymous DH: it just needs to be included in the
+     cipher list.
+     [Steve Henson]
+
+  *) Change the EVP_MD_CTX_type macro so its meaning consistent with
+     EVP_MD_type. The old functionality is available in a new macro called
+     EVP_MD_md(). Change code that uses it and update docs.
+     [Steve Henson]
+
+  *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
+     where the 'void *' argument is replaced by a function pointer argument.
+     Previously 'void *' was abused to point to functions, which works on
+     many platforms, but is not correct.  As these functions are usually
+     called by macros defined in OpenSSL header files, most source code
+     should work without changes.
+     [Richard Levitte]
+
+  *) <openssl/opensslconf.h> (which is created by Configure) now contains
+     sections with information on -D... compiler switches used for
+     compiling the library so that applications can see them.  To enable
+     one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
+     must be defined.  E.g.,
+        #define OPENSSL_ALGORITHM_DEFINES
+        #include <openssl/opensslconf.h>
+     defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
+     [Richard Levitte, Ulf and Bodo Möller]
+
+  *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
+     record layer.
+     [Bodo Moeller]
+
+  *) Change the 'other' type in certificate aux info to a STACK_OF
+     X509_ALGOR. Although not an AlgorithmIdentifier as such it has
+     the required ASN1 format: arbitrary types determined by an OID.
+     [Steve Henson]
+
+  *) Add some PEM_write_X509_REQ_NEW() functions and a command line
+     argument to 'req'. This is not because the function is newer or
+     better than others it just uses the work 'NEW' in the certificate
+     request header lines. Some software needs this.
+     [Steve Henson]
+
+  *) Reorganise password command line arguments: now passwords can be
+     obtained from various sources. Delete the PEM_cb function and make
+     it the default behaviour: i.e. if the callback is NULL and the
+     usrdata argument is not NULL interpret it as a null terminated pass
+     phrase. If usrdata and the callback are NULL then the pass phrase
+     is prompted for as usual.
+     [Steve Henson]
+
+  *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
+     the support is automatically enabled. The resulting binaries will
+     autodetect the card and use it if present.
+     [Ben Laurie and Compaq Inc.]
+
+  *) Work around for Netscape hang bug. This sends certificate request
+     and server done in one record. Since this is perfectly legal in the
+     SSL/TLS protocol it isn't a "bug" option and is on by default. See
+     the bugs/SSLv3 entry for more info.
+     [Steve Henson]
+
+  *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
+     [Andy Polyakov]
+
+  *) Add -rand argument to smime and pkcs12 applications and read/write
+     of seed file.
+     [Steve Henson]
+
+  *) New 'passwd' tool for crypt(3) and apr1 password hashes.
+     [Bodo Moeller]
+
+  *) Add command line password options to the remaining applications.
+     [Steve Henson]
+
+  *) Bug fix for BN_div_recp() for numerators with an even number of
+     bits.
+     [Ulf Möller]
+
+  *) More tests in bntest.c, and changed test_bn output.
+     [Ulf Möller]
+
+  *) ./config recognizes MacOS X now.
+     [Andy Polyakov]
+
+  *) Bug fix for BN_div() when the first words of num and divsor are
+     equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
+     [Ulf Möller]
+
+  *) Add support for various broken PKCS#8 formats, and command line
+     options to produce them.
+     [Steve Henson]
+
+  *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
+     get temporary BIGNUMs from a BN_CTX.
+     [Ulf Möller]
+
+  *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
+     for p == 0.
+     [Ulf Möller]
+
+  *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
+     include a #define from the old name to the new. The original intent
+     was that statically linked binaries could for example just call
+     SSLeay_add_all_ciphers() to just add ciphers to the table and not
+     link with digests. This never worked because SSLeay_add_all_digests()
+     and SSLeay_add_all_ciphers() were in the same source file so calling
+     one would link with the other. They are now in separate source files.
+     [Steve Henson]
+
+  *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
+     [Steve Henson]
+
+  *) Use a less unusual form of the Miller-Rabin primality test (it used
+     a binary algorithm for exponentiation integrated into the Miller-Rabin
+     loop, our standard modexp algorithms are faster).
+     [Bodo Moeller]
+
+  *) Support for the EBCDIC character set completed.
+     [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
+
+  *) Source code cleanups: use const where appropriate, eliminate casts,
+     use void * instead of char * in lhash.
+     [Ulf Möller] 
+
+  *) Bugfix: ssl3_send_server_key_exchange was not restartable
+     (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
+     this the server could overwrite ephemeral keys that the client
+     has already seen).
+     [Bodo Moeller]
+
+  *) Turn DSA_is_prime into a macro that calls BN_is_prime,
+     using 50 iterations of the Rabin-Miller test.
+
+     DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
+     iterations of the Rabin-Miller test as required by the appendix
+     to FIPS PUB 186[-1]) instead of DSA_is_prime.
+     As BN_is_prime_fasttest includes trial division, DSA parameter
+     generation becomes much faster.
+
+     This implies a change for the callback functions in DSA_is_prime
+     and DSA_generate_parameters: The callback function is called once
+     for each positive witness in the Rabin-Miller test, not just
+     occasionally in the inner loop; and the parameters to the
+     callback function now provide an iteration count for the outer
+     loop rather than for the current invocation of the inner loop.
+     DSA_generate_parameters additionally can call the callback
+     function with an 'iteration count' of -1, meaning that a
+     candidate has passed the trial division test (when q is generated 
+     from an application-provided seed, trial division is skipped).
+     [Bodo Moeller]
+
+  *) New function BN_is_prime_fasttest that optionally does trial
+     division before starting the Rabin-Miller test and has
+     an additional BN_CTX * argument (whereas BN_is_prime always
+     has to allocate at least one BN_CTX).
+     'callback(1, -1, cb_arg)' is called when a number has passed the
+     trial division stage.
+     [Bodo Moeller]
+
+  *) Fix for bug in CRL encoding. The validity dates weren't being handled
+     as ASN1_TIME.
+     [Steve Henson]
+
+  *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
+     [Steve Henson]
+
+  *) New function BN_pseudo_rand().
+     [Ulf Möller]
+
+  *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
+     bignum version of BN_from_montgomery() with the working code from
+     SSLeay 0.9.0 (the word based version is faster anyway), and clean up
+     the comments.
+     [Ulf Möller]
+
+  *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
+     made it impossible to use the same SSL_SESSION data structure in
+     SSL2 clients in multiple threads.
+     [Bodo Moeller]
+
+  *) The return value of RAND_load_file() no longer counts bytes obtained
+     by stat().  RAND_load_file(..., -1) is new and uses the complete file
+     to seed the PRNG (previously an explicit byte count was required).
+     [Ulf Möller, Bodo Möller]
+
+  *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
+     used (char *) instead of (void *) and had casts all over the place.
+     [Steve Henson]
+
+  *) Make BN_generate_prime() return NULL on error if ret!=NULL.
+     [Ulf Möller]
+
+  *) Retain source code compatibility for BN_prime_checks macro:
+     BN_is_prime(..., BN_prime_checks, ...) now uses
+     BN_prime_checks_for_size to determine the appropriate number of
+     Rabin-Miller iterations.
+     [Ulf Möller]
+
+  *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
+     DH_CHECK_P_NOT_SAFE_PRIME.
+     (Check if this is true? OpenPGP calls them "strong".)
+     [Ulf Möller]
+
+  *) Merge the functionality of "dh" and "gendh" programs into a new program
+     "dhparam". The old programs are retained for now but will handle DH keys
+     (instead of parameters) in future.
+     [Steve Henson]
+
+  *) Make the ciphers, s_server and s_client programs check the return values
+     when a new cipher list is set.
+     [Steve Henson]
+
+  *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
+     ciphers. Before when the 56bit ciphers were enabled the sorting was
+     wrong.
+
+     The syntax for the cipher sorting has been extended to support sorting by
+     cipher-strength (using the strength_bits hard coded in the tables).
+     The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
+
+     Fix a bug in the cipher-command parser: when supplying a cipher command
+     string with an "undefined" symbol (neither command nor alphanumeric
+     [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
+     an error is flagged.
+
+     Due to the strength-sorting extension, the code of the
+     ssl_create_cipher_list() function was completely rearranged. I hope that
+     the readability was also increased :-)
+     [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
+
+  *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
+     for the first serial number and places 2 in the serial number file. This
+     avoids problems when the root CA is created with serial number zero and
+     the first user certificate has the same issuer name and serial number
+     as the root CA.
+     [Steve Henson]
+
+  *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
+     the new code. Add documentation for this stuff.
+     [Steve Henson]
+
+  *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
+     X509_*() to X509at_*() on the grounds that they don't handle X509
+     structures and behave in an analogous way to the X509v3 functions:
+     they shouldn't be called directly but wrapper functions should be used
+     instead.
+
+     So we also now have some wrapper functions that call the X509at functions
+     when passed certificate requests. (TO DO: similar things can be done with
+     PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
+     things. Some of these need some d2i or i2d and print functionality
+     because they handle more complex structures.)
+     [Steve Henson]
+
+  *) Add missing #ifndefs that caused missing symbols when building libssl
+     as a shared library without RSA.  Use #ifndef NO_SSL2 instead of
+     NO_RSA in ssl/s2*.c. 
+     [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
+
+  *) Precautions against using the PRNG uninitialized: RAND_bytes() now
+     has a return value which indicates the quality of the random data
+     (1 = ok, 0 = not seeded).  Also an error is recorded on the thread's
+     error queue. New function RAND_pseudo_bytes() generates output that is
+     guaranteed to be unique but not unpredictable. RAND_add is like
+     RAND_seed, but takes an extra argument for an entropy estimate
+     (RAND_seed always assumes full entropy).
+     [Ulf Möller]
+
+  *) Do more iterations of Rabin-Miller probable prime test (specifically,
+     3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
+     instead of only 2 for all lengths; see BN_prime_checks_for_size definition
+     in crypto/bn/bn_prime.c for the complete table).  This guarantees a
+     false-positive rate of at most 2^-80 for random input.
+     [Bodo Moeller]
+
+  *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
+     [Bodo Moeller]
+
+  *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
+     in the 0.9.5 release), this returns the chain
+     from an X509_CTX structure with a dup of the stack and all
+     the X509 reference counts upped: so the stack will exist
+     after X509_CTX_cleanup() has been called. Modify pkcs12.c
+     to use this.
+
+     Also make SSL_SESSION_print() print out the verify return
+     code.
+     [Steve Henson]
+
+  *) Add manpage for the pkcs12 command. Also change the default
+     behaviour so MAC iteration counts are used unless the new
+     -nomaciter option is used. This improves file security and
+     only older versions of MSIE (4.0 for example) need it.
+     [Steve Henson]
+
+  *) Honor the no-xxx Configure options when creating .DEF files.
+     [Ulf Möller]
+
+  *) Add PKCS#10 attributes to field table: challengePassword, 
+     unstructuredName and unstructuredAddress. These are taken from
+     draft PKCS#9 v2.0 but are compatible with v1.2 provided no 
+     international characters are used.
+
+     More changes to X509_ATTRIBUTE code: allow the setting of types
+     based on strings. Remove the 'loc' parameter when adding
+     attributes because these will be a SET OF encoding which is sorted
+     in ASN1 order.
+     [Steve Henson]
+
+  *) Initial changes to the 'req' utility to allow request generation
+     automation. This will allow an application to just generate a template
+     file containing all the field values and have req construct the
+     request.
+
+     Initial support for X509_ATTRIBUTE handling. Stacks of these are
+     used all over the place including certificate requests and PKCS#7
+     structures. They are currently handled manually where necessary with
+     some primitive wrappers for PKCS#7. The new functions behave in a
+     manner analogous to the X509 extension functions: they allow
+     attributes to be looked up by NID and added.
+
+     Later something similar to the X509V3 code would be desirable to
+     automatically handle the encoding, decoding and printing of the
+     more complex types. The string types like challengePassword can
+     be handled by the string table functions.
+
+     Also modified the multi byte string table handling. Now there is
+     a 'global mask' which masks out certain types. The table itself
+     can use the flag STABLE_NO_MASK to ignore the mask setting: this
+     is useful when for example there is only one permissible type
+     (as in countryName) and using the mask might result in no valid
+     types at all.
+     [Steve Henson]
+
+  *) Clean up 'Finished' handling, and add functions SSL_get_finished and
+     SSL_get_peer_finished to allow applications to obtain the latest
+     Finished messages sent to the peer or expected from the peer,
+     respectively.  (SSL_get_peer_finished is usually the Finished message
+     actually received from the peer, otherwise the protocol will be aborted.)
+
+     As the Finished message are message digests of the complete handshake
+     (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
+     be used for external authentication procedures when the authentication
+     provided by SSL/TLS is not desired or is not enough.
+     [Bodo Moeller]
+
+  *) Enhanced support for Alpha Linux is added. Now ./config checks if
+     the host supports BWX extension and if Compaq C is present on the
+     $PATH. Just exploiting of the BWX extension results in 20-30%
+     performance kick for some algorithms, e.g. DES and RC4 to mention
+     a couple. Compaq C in turn generates ~20% faster code for MD5 and
+     SHA1.
+     [Andy Polyakov]
+
+  *) Add support for MS "fast SGC". This is arguably a violation of the
+     SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
+     weak crypto and after checking the certificate is SGC a second one
+     with strong crypto. MS SGC stops the first handshake after receiving
+     the server certificate message and sends a second client hello. Since
+     a server will typically do all the time consuming operations before
+     expecting any further messages from the client (server key exchange
+     is the most expensive) there is little difference between the two.
+
+     To get OpenSSL to support MS SGC we have to permit a second client
+     hello message after we have sent server done. In addition we have to
+     reset the MAC if we do get this second client hello.
+     [Steve Henson]
+
+  *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
+     if a DER encoded private key is RSA or DSA traditional format. Changed
+     d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
+     format DER encoded private key. Newer code should use PKCS#8 format which
+     has the key type encoded in the ASN1 structure. Added DER private key
+     support to pkcs8 application.
+     [Steve Henson]
+
+  *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
+     ciphersuites has been selected (as required by the SSL 3/TLS 1
+     specifications).  Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
+     is set, we interpret this as a request to violate the specification
+     (the worst that can happen is a handshake failure, and 'correct'
+     behaviour would result in a handshake failure anyway).
+     [Bodo Moeller]
+
+  *) In SSL_CTX_add_session, take into account that there might be multiple
+     SSL_SESSION structures with the same session ID (e.g. when two threads
+     concurrently obtain them from an external cache).
+     The internal cache can handle only one SSL_SESSION with a given ID,
+     so if there's a conflict, we now throw out the old one to achieve
+     consistency.
+     [Bodo Moeller]
+
+  *) Add OIDs for idea and blowfish in CBC mode. This will allow both
+     to be used in PKCS#5 v2.0 and S/MIME.  Also add checking to
+     some routines that use cipher OIDs: some ciphers do not have OIDs
+     defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
+     example.
+     [Steve Henson]
+
+  *) Simplify the trust setting structure and code. Now we just have
+     two sequences of OIDs for trusted and rejected settings. These will
+     typically have values the same as the extended key usage extension
+     and any application specific purposes.
+
+     The trust checking code now has a default behaviour: it will just
+     check for an object with the same NID as the passed id. Functions can
+     be provided to override either the default behaviour or the behaviour
+     for a given id. SSL client, server and email already have functions
+     in place for compatibility: they check the NID and also return "trusted"
+     if the certificate is self signed.
+     [Steve Henson]
+
+  *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
+     traditional format into an EVP_PKEY structure.
+     [Steve Henson]
+
+  *) Add a password callback function PEM_cb() which either prompts for
+     a password if usr_data is NULL or otherwise assumes it is a null
+     terminated password. Allow passwords to be passed on command line
+     environment or config files in a few more utilities.
+     [Steve Henson]
+
+  *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
+     keys. Add some short names for PKCS#8 PBE algorithms and allow them
+     to be specified on the command line for the pkcs8 and pkcs12 utilities.
+     Update documentation.
+     [Steve Henson]
+
+  *) Support for ASN1 "NULL" type. This could be handled before by using
+     ASN1_TYPE but there wasn't any function that would try to read a NULL
+     and produce an error if it couldn't. For compatibility we also have
+     ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
+     don't allocate anything because they don't need to.
+     [Steve Henson]
+
+  *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
+     for details.
+     [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
+
+  *) Rebuild of the memory allocation routines used by OpenSSL code and
+     possibly others as well.  The purpose is to make an interface that
+     provide hooks so anyone can build a separate set of allocation and
+     deallocation routines to be used by OpenSSL, for example memory
+     pool implementations, or something else, which was previously hard
+     since Malloc(), Realloc() and Free() were defined as macros having
+     the values malloc, realloc and free, respectively (except for Win32
+     compilations).  The same is provided for memory debugging code.
+     OpenSSL already comes with functionality to find memory leaks, but
+     this gives people a chance to debug other memory problems.
+
+     With these changes, a new set of functions and macros have appeared:
+
+       CRYPTO_set_mem_debug_functions()	        [F]
+       CRYPTO_get_mem_debug_functions()         [F]
+       CRYPTO_dbg_set_options()	                [F]
+       CRYPTO_dbg_get_options()                 [F]
+       CRYPTO_malloc_debug_init()               [M]
+
+     The memory debug functions are NULL by default, unless the library
+     is compiled with CRYPTO_MDEBUG or friends is defined.  If someone
+     wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
+     gives the standard debugging functions that come with OpenSSL) or
+     CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
+     provided by the library user) must be used.  When the standard
+     debugging functions are used, CRYPTO_dbg_set_options can be used to
+     request additional information:
+     CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
+     the CRYPTO_MDEBUG_xxx macro when compiling the library.   
+
+     Also, things like CRYPTO_set_mem_functions will always give the
+     expected result (the new set of functions is used for allocation
+     and deallocation) at all times, regardless of platform and compiler
+     options.
+
+     To finish it up, some functions that were never use in any other
+     way than through macros have a new API and new semantic:
+
+       CRYPTO_dbg_malloc()
+       CRYPTO_dbg_realloc()
+       CRYPTO_dbg_free()
+
+     All macros of value have retained their old syntax.
+     [Richard Levitte and Bodo Moeller]
+
+  *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
+     ordering of SMIMECapabilities wasn't in "strength order" and there
+     was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
+     algorithm.
+     [Steve Henson]
+
+  *) Some ASN1 types with illegal zero length encoding (INTEGER,
+     ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
+     [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
+
+  *) Merge in my S/MIME library for OpenSSL. This provides a simple
+     S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
+     functionality to handle multipart/signed properly) and a utility
+     called 'smime' to call all this stuff. This is based on code I
+     originally wrote for Celo who have kindly allowed it to be
+     included in OpenSSL.
+     [Steve Henson]
+
+  *) Add variants des_set_key_checked and des_set_key_unchecked of
+     des_set_key (aka des_key_sched).  Global variable des_check_key
+     decides which of these is called by des_set_key; this way
+     des_check_key behaves as it always did, but applications and
+     the library itself, which was buggy for des_check_key == 1,
+     have a cleaner way to pick the version they need.
+     [Bodo Moeller]
+
+  *) New function PKCS12_newpass() which changes the password of a
+     PKCS12 structure.
+     [Steve Henson]
+
+  *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
+     dynamic mix. In both cases the ids can be used as an index into the
+     table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
+     functions so they accept a list of the field values and the
+     application doesn't need to directly manipulate the X509_TRUST
+     structure.
+     [Steve Henson]
+
+  *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
+     need initialising.
+     [Steve Henson]
+
+  *) Modify the way the V3 extension code looks up extensions. This now
+     works in a similar way to the object code: we have some "standard"
+     extensions in a static table which is searched with OBJ_bsearch()
+     and the application can add dynamic ones if needed. The file
+     crypto/x509v3/ext_dat.h now has the info: this file needs to be
+     updated whenever a new extension is added to the core code and kept
+     in ext_nid order. There is a simple program 'tabtest.c' which checks
+     this. New extensions are not added too often so this file can readily
+     be maintained manually.
+
+     There are two big advantages in doing things this way. The extensions
+     can be looked up immediately and no longer need to be "added" using
+     X509V3_add_standard_extensions(): this function now does nothing.
+     [Side note: I get *lots* of email saying the extension code doesn't
+      work because people forget to call this function]
+     Also no dynamic allocation is done unless new extensions are added:
+     so if we don't add custom extensions there is no need to call
+     X509V3_EXT_cleanup().
+     [Steve Henson]
+
+  *) Modify enc utility's salting as follows: make salting the default. Add a
+     magic header, so unsalted files fail gracefully instead of just decrypting
+     to garbage. This is because not salting is a big security hole, so people
+     should be discouraged from doing it.
+     [Ben Laurie]
+
+  *) Fixes and enhancements to the 'x509' utility. It allowed a message
+     digest to be passed on the command line but it only used this
+     parameter when signing a certificate. Modified so all relevant
+     operations are affected by the digest parameter including the
+     -fingerprint and -x509toreq options. Also -x509toreq choked if a
+     DSA key was used because it didn't fix the digest.
+     [Steve Henson]
+
+  *) Initial certificate chain verify code. Currently tests the untrusted
+     certificates for consistency with the verify purpose (which is set
+     when the X509_STORE_CTX structure is set up) and checks the pathlength.
+
+     There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
+     this is because it will reject chains with invalid extensions whereas
+     every previous version of OpenSSL and SSLeay made no checks at all.
+
+     Trust code: checks the root CA for the relevant trust settings. Trust
+     settings have an initial value consistent with the verify purpose: e.g.
+     if the verify purpose is for SSL client use it expects the CA to be
+     trusted for SSL client use. However the default value can be changed to
+     permit custom trust settings: one example of this would be to only trust
+     certificates from a specific "secure" set of CAs.
+
+     Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
+     which should be used for version portability: especially since the
+     verify structure is likely to change more often now.
+
+     SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
+     to set them. If not set then assume SSL clients will verify SSL servers
+     and vice versa.
+
+     Two new options to the verify program: -untrusted allows a set of
+     untrusted certificates to be passed in and -purpose which sets the
+     intended purpose of the certificate. If a purpose is set then the
+     new chain verify code is used to check extension consistency.
+     [Steve Henson]
+
+  *) Support for the authority information access extension.
+     [Steve Henson]
+
+  *) Modify RSA and DSA PEM read routines to transparently handle
+     PKCS#8 format private keys. New *_PUBKEY_* functions that handle
+     public keys in a format compatible with certificate
+     SubjectPublicKeyInfo structures. Unfortunately there were already
+     functions called *_PublicKey_* which used various odd formats so
+     these are retained for compatibility: however the DSA variants were
+     never in a public release so they have been deleted. Changed dsa/rsa
+     utilities to handle the new format: note no releases ever handled public
+     keys so we should be OK.
+
+     The primary motivation for this change is to avoid the same fiasco
+     that dogs private keys: there are several incompatible private key
+     formats some of which are standard and some OpenSSL specific and
+     require various evil hacks to allow partial transparent handling and
+     even then it doesn't work with DER formats. Given the option anything
+     other than PKCS#8 should be dumped: but the other formats have to
+     stay in the name of compatibility.
+
+     With public keys and the benefit of hindsight one standard format 
+     is used which works with EVP_PKEY, RSA or DSA structures: though
+     it clearly returns an error if you try to read the wrong kind of key.
+
+     Added a -pubkey option to the 'x509' utility to output the public key.
+     Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
+     (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
+     EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
+     that do the same as the EVP_PKEY_assign_*() except they up the
+     reference count of the added key (they don't "swallow" the
+     supplied key).
+     [Steve Henson]
+
+  *) Fixes to crypto/x509/by_file.c the code to read in certificates and
+     CRLs would fail if the file contained no certificates or no CRLs:
+     added a new function to read in both types and return the number
+     read: this means that if none are read it will be an error. The
+     DER versions of the certificate and CRL reader would always fail
+     because it isn't possible to mix certificates and CRLs in DER format
+     without choking one or the other routine. Changed this to just read
+     a certificate: this is the best we can do. Also modified the code
+     in apps/verify.c to take notice of return codes: it was previously
+     attempting to read in certificates from NULL pointers and ignoring
+     any errors: this is one reason why the cert and CRL reader seemed
+     to work. It doesn't check return codes from the default certificate
+     routines: these may well fail if the certificates aren't installed.
+     [Steve Henson]
+
+  *) Code to support otherName option in GeneralName.
+     [Steve Henson]
+
+  *) First update to verify code. Change the verify utility
+     so it warns if it is passed a self signed certificate:
+     for consistency with the normal behaviour. X509_verify
+     has been modified to it will now verify a self signed
+     certificate if *exactly* the same certificate appears
+     in the store: it was previously impossible to trust a
+     single self signed certificate. This means that:
+     openssl verify ss.pem
+     now gives a warning about a self signed certificate but
+     openssl verify -CAfile ss.pem ss.pem
+     is OK.
+     [Steve Henson]
+
+  *) For servers, store verify_result in SSL_SESSION data structure
+     (and add it to external session representation).
+     This is needed when client certificate verifications fails,
+     but an application-provided verification callback (set by
+     SSL_CTX_set_cert_verify_callback) allows accepting the session
+     anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
+     but returns 1): When the session is reused, we have to set
+     ssl->verify_result to the appropriate error code to avoid
+     security holes.
+     [Bodo Moeller, problem pointed out by Lutz Jaenicke]
+
+  *) Fix a bug in the new PKCS#7 code: it didn't consider the
+     case in PKCS7_dataInit() where the signed PKCS7 structure
+     didn't contain any existing data because it was being created.
+     [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
+
+  *) Add a salt to the key derivation routines in enc.c. This
+     forms the first 8 bytes of the encrypted file. Also add a
+     -S option to allow a salt to be input on the command line.
+     [Steve Henson]
+
+  *) New function X509_cmp(). Oddly enough there wasn't a function
+     to compare two certificates. We do this by working out the SHA1
+     hash and comparing that. X509_cmp() will be needed by the trust
+     code.
+     [Steve Henson]
+
+  *) SSL_get1_session() is like SSL_get_session(), but increments
+     the reference count in the SSL_SESSION returned.
+     [Geoff Thorpe <geoff@eu.c2.net>]
+
+  *) Fix for 'req': it was adding a null to request attributes.
+     Also change the X509_LOOKUP and X509_INFO code to handle
+     certificate auxiliary information.
+     [Steve Henson]
+
+  *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
+     the 'enc' command.
+     [Steve Henson]
+
+  *) Add the possibility to add extra information to the memory leak
+     detecting output, to form tracebacks, showing from where each
+     allocation was originated: CRYPTO_push_info("constant string") adds
+     the string plus current file name and line number to a per-thread
+     stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
+     is like calling CYRPTO_pop_info() until the stack is empty.
+     Also updated memory leak detection code to be multi-thread-safe.
+     [Richard Levitte]
+
+  *) Add options -text and -noout to pkcs7 utility and delete the
+     encryption options which never did anything. Update docs.
+     [Steve Henson]
+
+  *) Add options to some of the utilities to allow the pass phrase
+     to be included on either the command line (not recommended on
+     OSes like Unix) or read from the environment. Update the
+     manpages and fix a few bugs.
+     [Steve Henson]
+
+  *) Add a few manpages for some of the openssl commands.
+     [Steve Henson]
+
+  *) Fix the -revoke option in ca. It was freeing up memory twice,
+     leaking and not finding already revoked certificates.
+     [Steve Henson]
+
+  *) Extensive changes to support certificate auxiliary information.
+     This involves the use of X509_CERT_AUX structure and X509_AUX
+     functions. An X509_AUX function such as PEM_read_X509_AUX()
+     can still read in a certificate file in the usual way but it
+     will also read in any additional "auxiliary information". By
+     doing things this way a fair degree of compatibility can be
+     retained: existing certificates can have this information added
+     using the new 'x509' options. 
+
+     Current auxiliary information includes an "alias" and some trust
+     settings. The trust settings will ultimately be used in enhanced
+     certificate chain verification routines: currently a certificate
+     can only be trusted if it is self signed and then it is trusted
+     for all purposes.
+     [Steve Henson]
+
+  *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
+     The problem was that one of the replacement routines had not been working
+     since SSLeay releases.  For now the offending routine has been replaced
+     with non-optimised assembler.  Even so, this now gives around 95%
+     performance improvement for 1024 bit RSA signs.
+     [Mark Cox]
+
+  *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 
+     handling. Most clients have the effective key size in bits equal to
+     the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
+     A few however don't do this and instead use the size of the decrypted key
+     to determine the RC2 key length and the AlgorithmIdentifier to determine
+     the effective key length. In this case the effective key length can still
+     be 40 bits but the key length can be 168 bits for example. This is fixed
+     by manually forcing an RC2 key into the EVP_PKEY structure because the
+     EVP code can't currently handle unusual RC2 key sizes: it always assumes
+     the key length and effective key length are equal.
+     [Steve Henson]
+
+  *) Add a bunch of functions that should simplify the creation of 
+     X509_NAME structures. Now you should be able to do:
+     X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
+     and have it automatically work out the correct field type and fill in
+     the structures. The more adventurous can try:
+     X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
+     and it will (hopefully) work out the correct multibyte encoding.
+     [Steve Henson]
+
+  *) Change the 'req' utility to use the new field handling and multibyte
+     copy routines. Before the DN field creation was handled in an ad hoc
+     way in req, ca, and x509 which was rather broken and didn't support
+     BMPStrings or UTF8Strings. Since some software doesn't implement
+     BMPStrings or UTF8Strings yet, they can be enabled using the config file
+     using the dirstring_type option. See the new comment in the default
+     openssl.cnf for more info.
+     [Steve Henson]
+
+  *) Make crypto/rand/md_rand.c more robust:
+     - Assure unique random numbers after fork().
+     - Make sure that concurrent threads access the global counter and
+       md serializably so that we never lose entropy in them
+       or use exactly the same state in multiple threads.
+       Access to the large state is not always serializable because
+       the additional locking could be a performance killer, and
+       md should be large enough anyway.
+     [Bodo Moeller]
+
+  *) New file apps/app_rand.c with commonly needed functionality
+     for handling the random seed file.
+
+     Use the random seed file in some applications that previously did not:
+          ca,
+          dsaparam -genkey (which also ignored its '-rand' option), 
+          s_client,
+          s_server,
+          x509 (when signing).
+     Except on systems with /dev/urandom, it is crucial to have a random
+     seed file at least for key creation, DSA signing, and for DH exchanges;
+     for RSA signatures we could do without one.
+
+     gendh and gendsa (unlike genrsa) used to read only the first byte
+     of each file listed in the '-rand' option.  The function as previously
+     found in genrsa is now in app_rand.c and is used by all programs
+     that support '-rand'.
+     [Bodo Moeller]
+
+  *) In RAND_write_file, use mode 0600 for creating files;
+     don't just chmod when it may be too late.
+     [Bodo Moeller]
+
+  *) Report an error from X509_STORE_load_locations
+     when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
+     [Bill Perry]
+
+  *) New function ASN1_mbstring_copy() this copies a string in either
+     ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
+     into an ASN1_STRING type. A mask of permissible types is passed
+     and it chooses the "minimal" type to use or an error if not type
+     is suitable.
+     [Steve Henson]
+
+  *) Add function equivalents to the various macros in asn1.h. The old
+     macros are retained with an M_ prefix. Code inside the library can
+     use the M_ macros. External code (including the openssl utility)
+     should *NOT* in order to be "shared library friendly".
+     [Steve Henson]
+
+  *) Add various functions that can check a certificate's extensions
+     to see if it usable for various purposes such as SSL client,
+     server or S/MIME and CAs of these types. This is currently 
+     VERY EXPERIMENTAL but will ultimately be used for certificate chain
+     verification. Also added a -purpose flag to x509 utility to
+     print out all the purposes.
+     [Steve Henson]
+
+  *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
+     functions.
+     [Steve Henson]
+
+  *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
+     for, obtain and decode and extension and obtain its critical flag.
+     This allows all the necessary extension code to be handled in a
+     single function call.
+     [Steve Henson]
+
+  *) RC4 tune-up featuring 30-40% performance improvement on most RISC
+     platforms. See crypto/rc4/rc4_enc.c for further details.
+     [Andy Polyakov]
+
+  *) New -noout option to asn1parse. This causes no output to be produced
+     its main use is when combined with -strparse and -out to extract data
+     from a file (which may not be in ASN.1 format).
+     [Steve Henson]
+
+  *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
+     when producing the local key id.
+     [Richard Levitte <levitte@stacken.kth.se>]
+
+  *) New option -dhparam in s_server. This allows a DH parameter file to be
+     stated explicitly. If it is not stated then it tries the first server
+     certificate file. The previous behaviour hard coded the filename
+     "server.pem".
+     [Steve Henson]
+
+  *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
+     a public key to be input or output. For example:
+     openssl rsa -in key.pem -pubout -out pubkey.pem
+     Also added necessary DSA public key functions to handle this.
+     [Steve Henson]
+
+  *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
+     in the message. This was handled by allowing
+     X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
+     [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
+
+  *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
+     to the end of the strings whereas this didn't. This would cause problems
+     if strings read with d2i_ASN1_bytes() were later modified.
+     [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
+
+  *) Fix for base64 decode bug. When a base64 bio reads only one line of
+     data and it contains EOF it will end up returning an error. This is
+     caused by input 46 bytes long. The cause is due to the way base64
+     BIOs find the start of base64 encoded data. They do this by trying a
+     trial decode on each line until they find one that works. When they
+     do a flag is set and it starts again knowing it can pass all the
+     data directly through the decoder. Unfortunately it doesn't reset
+     the context it uses. This means that if EOF is reached an attempt
+     is made to pass two EOFs through the context and this causes the
+     resulting error. This can also cause other problems as well. As is
+     usual with these problems it takes *ages* to find and the fix is
+     trivial: move one line.
+     [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
+
+  *) Ugly workaround to get s_client and s_server working under Windows. The
+     old code wouldn't work because it needed to select() on sockets and the
+     tty (for keypresses and to see if data could be written). Win32 only
+     supports select() on sockets so we select() with a 1s timeout on the
+     sockets and then see if any characters are waiting to be read, if none
+     are present then we retry, we also assume we can always write data to
+     the tty. This isn't nice because the code then blocks until we've
+     received a complete line of data and it is effectively polling the
+     keyboard at 1s intervals: however it's quite a bit better than not
+     working at all :-) A dedicated Windows application might handle this
+     with an event loop for example.
+     [Steve Henson]
+
+  *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
+     and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
+     will be called when RSA_sign() and RSA_verify() are used. This is useful
+     if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
+     For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
+     should *not* be used: RSA_sign() and RSA_verify() must be used instead.
+     This necessitated the support of an extra signature type NID_md5_sha1
+     for SSL signatures and modifications to the SSL library to use it instead
+     of calling RSA_public_decrypt() and RSA_private_encrypt().
+     [Steve Henson]
+
+  *) Add new -verify -CAfile and -CApath options to the crl program, these
+     will lookup a CRL issuers certificate and verify the signature in a
+     similar way to the verify program. Tidy up the crl program so it
+     no longer accesses structures directly. Make the ASN1 CRL parsing a bit
+     less strict. It will now permit CRL extensions even if it is not
+     a V2 CRL: this will allow it to tolerate some broken CRLs.
+     [Steve Henson]
+
+  *) Initialize all non-automatic variables each time one of the openssl
+     sub-programs is started (this is necessary as they may be started
+     multiple times from the "OpenSSL>" prompt).
+     [Lennart Bang, Bodo Moeller]
+
+  *) Preliminary compilation option RSA_NULL which disables RSA crypto without
+     removing all other RSA functionality (this is what NO_RSA does). This
+     is so (for example) those in the US can disable those operations covered
+     by the RSA patent while allowing storage and parsing of RSA keys and RSA
+     key generation.
+     [Steve Henson]
+
+  *) Non-copying interface to BIO pairs.
+     (still largely untested)
+     [Bodo Moeller]
+
+  *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
+     ASCII string. This was handled independently in various places before.
+     [Steve Henson]
+
+  *) New functions UTF8_getc() and UTF8_putc() that parse and generate
+     UTF8 strings a character at a time.
+     [Steve Henson]
+
+  *) Use client_version from client hello to select the protocol
+     (s23_srvr.c) and for RSA client key exchange verification
+     (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
+     [Bodo Moeller]
+
+  *) Add various utility functions to handle SPKACs, these were previously
+     handled by poking round in the structure internals. Added new function
+     NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
+     print, verify and generate SPKACs. Based on an original idea from
+     Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
+     [Steve Henson]
+
+  *) RIPEMD160 is operational on all platforms and is back in 'make test'.
+     [Andy Polyakov]
+
+  *) Allow the config file extension section to be overwritten on the
+     command line. Based on an original idea from Massimiliano Pala
+     <madwolf@comune.modena.it>. The new option is called -extensions
+     and can be applied to ca, req and x509. Also -reqexts to override
+     the request extensions in req and -crlexts to override the crl extensions
+     in ca.
+     [Steve Henson]
+
+  *) Add new feature to the SPKAC handling in ca.  Now you can include
+     the same field multiple times by preceding it by "XXXX." for example:
+     1.OU="Unit name 1"
+     2.OU="Unit name 2"
+     this is the same syntax as used in the req config file.
+     [Steve Henson]
+
+  *) Allow certificate extensions to be added to certificate requests. These
+     are specified in a 'req_extensions' option of the req section of the
+     config file. They can be printed out with the -text option to req but
+     are otherwise ignored at present.
+     [Steve Henson]
+
+  *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
+     data read consists of only the final block it would not decrypted because
+     EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
+     A misplaced 'break' also meant the decrypted final block might not be
+     copied until the next read.
+     [Steve Henson]
+
+  *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
+     a few extra parameters to the DH structure: these will be useful if
+     for example we want the value of 'q' or implement X9.42 DH.
+     [Steve Henson]
+
+  *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
+     provides hooks that allow the default DSA functions or functions on a
+     "per key" basis to be replaced. This allows hardware acceleration and
+     hardware key storage to be handled without major modification to the
+     library. Also added low level modexp hooks and CRYPTO_EX structure and 
+     associated functions.
+     [Steve Henson]
+
+  *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
+     as "read only": it can't be written to and the buffer it points to will
+     not be freed. Reading from a read only BIO is much more efficient than
+     a normal memory BIO. This was added because there are several times when
+     an area of memory needs to be read from a BIO. The previous method was
+     to create a memory BIO and write the data to it, this results in two
+     copies of the data and an O(n^2) reading algorithm. There is a new
+     function BIO_new_mem_buf() which creates a read only memory BIO from
+     an area of memory. Also modified the PKCS#7 routines to use read only
+     memory BIOs.
+     [Steve Henson]
+
+  *) Bugfix: ssl23_get_client_hello did not work properly when called in
+     state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
+     a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
+     but a retry condition occurred while trying to read the rest.
+     [Bodo Moeller]
+
+  *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
+     NID_pkcs7_encrypted by default: this was wrong since this should almost
+     always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
+     the encrypted data type: this is a more sensible place to put it and it
+     allows the PKCS#12 code to be tidied up that duplicated this
+     functionality.
+     [Steve Henson]
+
+  *) Changed obj_dat.pl script so it takes its input and output files on
+     the command line. This should avoid shell escape redirection problems
+     under Win32.
+     [Steve Henson]
+
+  *) Initial support for certificate extension requests, these are included
+     in things like Xenroll certificate requests. Included functions to allow
+     extensions to be obtained and added.
+     [Steve Henson]
+
+  *) -crlf option to s_client and s_server for sending newlines as
+     CRLF (as required by many protocols).
+     [Bodo Moeller]
+
+ Changes between 0.9.3a and 0.9.4  [09 Aug 1999]
+  
+  *) Install libRSAglue.a when OpenSSL is built with RSAref.
+     [Ralf S. Engelschall]
+
+  *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
+     [Andrija Antonijevic <TheAntony2@bigfoot.com>]
+
+  *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
+     program.
+     [Steve Henson]
+
+  *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
+     DH parameters/keys (q is lost during that conversion, but the resulting
+     DH parameters contain its length).
+
+     For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
+     much faster than DH_generate_parameters (which creates parameters
+     where p = 2*q + 1), and also the smaller q makes DH computations
+     much more efficient (160-bit exponentiation instead of 1024-bit
+     exponentiation); so this provides a convenient way to support DHE
+     ciphersuites in SSL/TLS servers (see ssl/ssltest.c).  It is of
+     utter importance to use
+         SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
+     or
+         SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
+     when such DH parameters are used, because otherwise small subgroup
+     attacks may become possible!
+     [Bodo Moeller]
+
+  *) Avoid memory leak in i2d_DHparams.
+     [Bodo Moeller]
+
+  *) Allow the -k option to be used more than once in the enc program:
+     this allows the same encrypted message to be read by multiple recipients.
+     [Steve Henson]
+
+  *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
+     an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
+     it will always use the numerical form of the OID, even if it has a short
+     or long name.
+     [Steve Henson]
+
+  *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
+     method only got called if p,q,dmp1,dmq1,iqmp components were present,
+     otherwise bn_mod_exp was called. In the case of hardware keys for example
+     no private key components need be present and it might store extra data
+     in the RSA structure, which cannot be accessed from bn_mod_exp.
+     By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
+     private key operations.
+     [Steve Henson]
+
+  *) Added support for SPARC Linux.
+     [Andy Polyakov]
+
+  *) pem_password_cb function type incompatibly changed from
+          typedef int pem_password_cb(char *buf, int size, int rwflag);
+     to
+          ....(char *buf, int size, int rwflag, void *userdata);
+     so that applications can pass data to their callbacks:
+     The PEM[_ASN1]_{read,write}... functions and macros now take an
+     additional void * argument, which is just handed through whenever
+     the password callback is called.
+     [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
+
+     New function SSL_CTX_set_default_passwd_cb_userdata.
+
+     Compatibility note: As many C implementations push function arguments
+     onto the stack in reverse order, the new library version is likely to
+     interoperate with programs that have been compiled with the old
+     pem_password_cb definition (PEM_whatever takes some data that
+     happens to be on the stack as its last argument, and the callback
+     just ignores this garbage); but there is no guarantee whatsoever that
+     this will work.
+
+  *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
+     (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
+     problems not only on Windows, but also on some Unix platforms.
+     To avoid problematic command lines, these definitions are now in an
+     auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
+     for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
+     [Bodo Moeller]
+
+  *) MIPS III/IV assembler module is reimplemented.
+     [Andy Polyakov]
+
+  *) More DES library cleanups: remove references to srand/rand and
+     delete an unused file.
+     [Ulf Möller]
+
+  *) Add support for the the free Netwide assembler (NASM) under Win32,
+     since not many people have MASM (ml) and it can be hard to obtain.
+     This is currently experimental but it seems to work OK and pass all
+     the tests. Check out INSTALL.W32 for info.
+     [Steve Henson]
+
+  *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
+     without temporary keys kept an extra copy of the server key,
+     and connections with temporary keys did not free everything in case
+     of an error.
+     [Bodo Moeller]
+
+  *) New function RSA_check_key and new openssl rsa option -check
+     for verifying the consistency of RSA keys.
+     [Ulf Moeller, Bodo Moeller]
+
+  *) Various changes to make Win32 compile work: 
+     1. Casts to avoid "loss of data" warnings in p5_crpt2.c
+     2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
+        comparison" warnings.
+     3. Add sk_<TYPE>_sort to DEF file generator and do make update.
+     [Steve Henson]
+
+  *) Add a debugging option to PKCS#5 v2 key generation function: when
+     you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
+     derived keys are printed to stderr.
+     [Steve Henson]
+
+  *) Copy the flags in ASN1_STRING_dup().
+     [Roman E. Pavlov <pre@mo.msk.ru>]
+
+  *) The x509 application mishandled signing requests containing DSA
+     keys when the signing key was also DSA and the parameters didn't match.
+
+     It was supposed to omit the parameters when they matched the signing key:
+     the verifying software was then supposed to automatically use the CA's
+     parameters if they were absent from the end user certificate.
+
+     Omitting parameters is no longer recommended. The test was also
+     the wrong way round! This was probably due to unusual behaviour in
+     EVP_cmp_parameters() which returns 1 if the parameters match. 
+     This meant that parameters were omitted when they *didn't* match and
+     the certificate was useless. Certificates signed with 'ca' didn't have
+     this bug.
+     [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
+
+  *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
+     The interface is as follows:
+     Applications can use
+         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
+         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
+     "off" is now the default.
+     The library internally uses
+         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
+         CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
+     to disable memory-checking temporarily.
+
+     Some inconsistent states that previously were possible (and were
+     even the default) are now avoided.
+
+     -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
+     with each memory chunk allocated; this is occasionally more helpful
+     than just having a counter.
+
+     -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
+
+     -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
+     extensions.
+     [Bodo Moeller]
+
+  *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
+     which largely parallels "options", but is for changing API behaviour,
+     whereas "options" are about protocol behaviour.
+     Initial "mode" flags are:
+
+     SSL_MODE_ENABLE_PARTIAL_WRITE   Allow SSL_write to report success when
+                                     a single record has been written.
+     SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER  Don't insist that SSL_write
+                                     retries use the same buffer location.
+                                     (But all of the contents must be
+                                     copied!)
+     [Bodo Moeller]
+
+  *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
+     worked.
+
+  *) Fix problems with no-hmac etc.
+     [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
+
+  *) New functions RSA_get_default_method(), RSA_set_method() and
+     RSA_get_method(). These allows replacement of RSA_METHODs without having
+     to mess around with the internals of an RSA structure.
+     [Steve Henson]
+
+  *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
+     Also really enable memory leak checks in openssl.c and in some
+     test programs.
+     [Chad C. Mulligan, Bodo Moeller]
+
+  *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
+     up the length of negative integers. This has now been simplified to just
+     store the length when it is first determined and use it later, rather
+     than trying to keep track of where data is copied and updating it to
+     point to the end.
+     [Steve Henson, reported by Brien Wheeler
+      <bwheeler@authentica-security.com>]
+
+  *) Add a new function PKCS7_signatureVerify. This allows the verification
+     of a PKCS#7 signature but with the signing certificate passed to the
+     function itself. This contrasts with PKCS7_dataVerify which assumes the
+     certificate is present in the PKCS#7 structure. This isn't always the
+     case: certificates can be omitted from a PKCS#7 structure and be
+     distributed by "out of band" means (such as a certificate database).
+     [Steve Henson]
+
+  *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
+     function prototypes in pem.h, also change util/mkdef.pl to add the
+     necessary function names. 
+     [Steve Henson]
+
+  *) mk1mf.pl (used by Windows builds) did not properly read the
+     options set by Configure in the top level Makefile, and Configure
+     was not even able to write more than one option correctly.
+     Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
+     [Bodo Moeller]
+
+  *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
+     file to be loaded from a BIO or FILE pointer. The BIO version will
+     for example allow memory BIOs to contain config info.
+     [Steve Henson]
+
+  *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
+     Whoever hopes to achieve shared-library compatibility across versions
+     must use this, not the compile-time macro.
+     (Exercise 0.9.4: Which is the minimum library version required by
+     such programs?)
+     Note: All this applies only to multi-threaded programs, others don't
+     need locks.
+     [Bodo Moeller]
+
+  *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
+     through a BIO pair triggered the default case, i.e.
+     SSLerr(...,SSL_R_UNKNOWN_STATE).
+     [Bodo Moeller]
+
+  *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
+     can use the SSL library even if none of the specific BIOs is
+     appropriate.
+     [Bodo Moeller]
+
+  *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
+     for the encoded length.
+     [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
+
+  *) Add initial documentation of the X509V3 functions.
+     [Steve Henson]
+
+  *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and 
+     PEM_write_bio_PKCS8PrivateKey() that are equivalent to
+     PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
+     secure PKCS#8 private key format with a high iteration count.
+     [Steve Henson]
+
+  *) Fix determination of Perl interpreter: A perl or perl5
+     _directory_ in $PATH was also accepted as the interpreter.
+     [Ralf S. Engelschall]
+
+  *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
+     wrong with it but it was very old and did things like calling
+     PEM_ASN1_read() directly and used MD5 for the hash not to mention some
+     unusual formatting.
+     [Steve Henson]
+
+  *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
+     to use the new extension code.
+     [Steve Henson]
+
+  *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
+     with macros. This should make it easier to change their form, add extra
+     arguments etc. Fix a few PEM prototypes which didn't have cipher as a
+     constant.
+     [Steve Henson]
+
+  *) Add to configuration table a new entry that can specify an alternative
+     name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
+     according to Mark Crispin <MRC@Panda.COM>.
+     [Bodo Moeller]
+
+#if 0
+  *) DES CBC did not update the IV. Weird.
+     [Ben Laurie]
+#else
+     des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
+     Changing the behaviour of the former might break existing programs --
+     where IV updating is needed, des_ncbc_encrypt can be used.
+#endif
+
+  *) When bntest is run from "make test" it drives bc to check its
+     calculations, as well as internally checking them. If an internal check
+     fails, it needs to cause bc to give a non-zero result or make test carries
+     on without noticing the failure. Fixed.
+     [Ben Laurie]
+
+  *) DES library cleanups.
+     [Ulf Möller]
+
+  *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
+     used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
+     ciphers. NOTE: although the key derivation function has been verified
+     against some published test vectors it has not been extensively tested
+     yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
+     of v2.0.
+     [Steve Henson]
+
+  *) Instead of "mkdir -p", which is not fully portable, use new
+     Perl script "util/mkdir-p.pl".
+     [Bodo Moeller]
+
+  *) Rewrite the way password based encryption (PBE) is handled. It used to
+     assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
+     structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
+     but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
+     the 'parameter' field of the AlgorithmIdentifier is passed to the
+     underlying key generation function so it must do its own ASN1 parsing.
+     This has also changed the EVP_PBE_CipherInit() function which now has a
+     'parameter' argument instead of literal salt and iteration count values
+     and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
+     [Steve Henson]
+
+  *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
+     and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
+     Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
+     KEY" because this clashed with PKCS#8 unencrypted string. Since this
+     value was just used as a "magic string" and not used directly its
+     value doesn't matter.
+     [Steve Henson]
+
+  *) Introduce some semblance of const correctness to BN. Shame C doesn't
+     support mutable.
+     [Ben Laurie]
+
+  *) "linux-sparc64" configuration (ultrapenguin).
+     [Ray Miller <ray.miller@oucs.ox.ac.uk>]
+     "linux-sparc" configuration.
+     [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
+
+  *) config now generates no-xxx options for missing ciphers.
+     [Ulf Möller]
+
+  *) Support the EBCDIC character set (work in progress).
+     File ebcdic.c not yet included because it has a different license.
+     [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
+
+  *) Support BS2000/OSD-POSIX.
+     [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
+
+  *) Make callbacks for key generation use void * instead of char *.
+     [Ben Laurie]
+
+  *) Make S/MIME samples compile (not yet tested).
+     [Ben Laurie]
+
+  *) Additional typesafe stacks.
+     [Ben Laurie]
+
+  *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
+     [Bodo Moeller]
+
+
+ Changes between 0.9.3 and 0.9.3a  [29 May 1999]
+
+  *) New configuration variant "sco5-gcc".
+
+  *) Updated some demos.
+     [Sean O Riordain, Wade Scholine]
+
+  *) Add missing BIO_free at exit of pkcs12 application.
+     [Wu Zhigang]
+
+  *) Fix memory leak in conf.c.
+     [Steve Henson]
+
+  *) Updates for Win32 to assembler version of MD5.
+     [Steve Henson]
+
+  *) Set #! path to perl in apps/der_chop to where we found it
+     instead of using a fixed path.
+     [Bodo Moeller]
+
+  *) SHA library changes for irix64-mips4-cc.
+     [Andy Polyakov]
+
+  *) Improvements for VMS support.
+     [Richard Levitte]
+
+
+ Changes between 0.9.2b and 0.9.3  [24 May 1999]
+
+  *) Bignum library bug fix. IRIX 6 passes "make test" now!
+     This also avoids the problems with SC4.2 and unpatched SC5.  
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) New functions sk_num, sk_value and sk_set to replace the previous macros.
+     These are required because of the typesafe stack would otherwise break 
+     existing code. If old code used a structure member which used to be STACK
+     and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
+     sk_num or sk_value it would produce an error because the num, data members
+     are not present in STACK_OF. Now it just produces a warning. sk_set
+     replaces the old method of assigning a value to sk_value
+     (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
+     that does this will no longer work (and should use sk_set instead) but
+     this could be regarded as a "questionable" behaviour anyway.
+     [Steve Henson]
+
+  *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
+     correctly handle encrypted S/MIME data.
+     [Steve Henson]
+
+  *) Change type of various DES function arguments from des_cblock
+     (which means, in function argument declarations, pointer to char)
+     to des_cblock * (meaning pointer to array with 8 char elements),
+     which allows the compiler to do more typechecking; it was like
+     that back in SSLeay, but with lots of ugly casts.
+
+     Introduce new type const_des_cblock.
+     [Bodo Moeller]
+
+  *) Reorganise the PKCS#7 library and get rid of some of the more obvious
+     problems: find RecipientInfo structure that matches recipient certificate
+     and initialise the ASN1 structures properly based on passed cipher.
+     [Steve Henson]
+
+  *) Belatedly make the BN tests actually check the results.
+     [Ben Laurie]
+
+  *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
+     to and from BNs: it was completely broken. New compilation option
+     NEG_PUBKEY_BUG to allow for some broken certificates that encode public
+     key elements as negative integers.
+     [Steve Henson]
+
+  *) Reorganize and speed up MD5.
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) VMS support.
+     [Richard Levitte <richard@levitte.org>]
+
+  *) New option -out to asn1parse to allow the parsed structure to be
+     output to a file. This is most useful when combined with the -strparse
+     option to examine the output of things like OCTET STRINGS.
+     [Steve Henson]
+
+  *) Make SSL library a little more fool-proof by not requiring any longer
+     that SSL_set_{accept,connect}_state be called before
+     SSL_{accept,connect} may be used (SSL_set_..._state is omitted
+     in many applications because usually everything *appeared* to work as
+     intended anyway -- now it really works as intended).
+     [Bodo Moeller]
+
+  *) Move openssl.cnf out of lib/.
+     [Ulf Möller]
+
+  *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
+     -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
+     -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ 
+     [Ralf S. Engelschall]
+
+  *) Various fixes to the EVP and PKCS#7 code. It may now be able to
+     handle PKCS#7 enveloped data properly.
+     [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
+
+  *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
+     copying pointers.  The cert_st handling is changed by this in
+     various ways (and thus what used to be known as ctx->default_cert
+     is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
+     any longer when s->cert does not give us what we need).
+     ssl_cert_instantiate becomes obsolete by this change.
+     As soon as we've got the new code right (possibly it already is?),
+     we have solved a couple of bugs of the earlier code where s->cert
+     was used as if it could not have been shared with other SSL structures.
+
+     Note that using the SSL API in certain dirty ways now will result
+     in different behaviour than observed with earlier library versions:
+     Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
+     does not influence s as it used to.
+     
+     In order to clean up things more thoroughly, inside SSL_SESSION
+     we don't use CERT any longer, but a new structure SESS_CERT
+     that holds per-session data (if available); currently, this is
+     the peer's certificate chain and, for clients, the server's certificate
+     and temporary key.  CERT holds only those values that can have
+     meaningful defaults in an SSL_CTX.
+     [Bodo Moeller]
+
+  *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
+     from the internal representation. Various PKCS#7 fixes: remove some
+     evil casts and set the enc_dig_alg field properly based on the signing
+     key type.
+     [Steve Henson]
+
+  *) Allow PKCS#12 password to be set from the command line or the
+     environment. Let 'ca' get its config file name from the environment
+     variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
+     and 'x509').
+     [Steve Henson]
+
+  *) Allow certificate policies extension to use an IA5STRING for the
+     organization field. This is contrary to the PKIX definition but
+     VeriSign uses it and IE5 only recognises this form. Document 'x509'
+     extension option.
+     [Steve Henson]
+
+  *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
+     without disallowing inline assembler and the like for non-pedantic builds.
+     [Ben Laurie]
+
+  *) Support Borland C++ builder.
+     [Janez Jere <jj@void.si>, modified by Ulf Möller]
+
+  *) Support Mingw32.
+     [Ulf Möller]
+
+  *) SHA-1 cleanups and performance enhancements.
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) Sparc v8plus assembler for the bignum library.
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) Accept any -xxx and +xxx compiler options in Configure.
+     [Ulf Möller]
+
+  *) Update HPUX configuration.
+     [Anonymous]
+  
+  *) Add missing sk_<type>_unshift() function to safestack.h
+     [Ralf S. Engelschall]
+
+  *) New function SSL_CTX_use_certificate_chain_file that sets the
+     "extra_cert"s in addition to the certificate.  (This makes sense
+     only for "PEM" format files, as chains as a whole are not
+     DER-encoded.)
+     [Bodo Moeller]
+
+  *) Support verify_depth from the SSL API.
+     x509_vfy.c had what can be considered an off-by-one-error:
+     Its depth (which was not part of the external interface)
+     was actually counting the number of certificates in a chain;
+     now it really counts the depth.
+     [Bodo Moeller]
+
+  *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
+     instead of X509err, which often resulted in confusing error
+     messages since the error codes are not globally unique
+     (e.g. an alleged error in ssl3_accept when a certificate
+     didn't match the private key).
+
+  *) New function SSL_CTX_set_session_id_context that allows to set a default
+     value (so that you don't need SSL_set_session_id_context for each
+     connection using the SSL_CTX).
+     [Bodo Moeller]
+
+  *) OAEP decoding bug fix.
+     [Ulf Möller]
+
+  *) Support INSTALL_PREFIX for package builders, as proposed by
+     David Harris.
+     [Bodo Moeller]
+
+  *) New Configure options "threads" and "no-threads".  For systems
+     where the proper compiler options are known (currently Solaris
+     and Linux), "threads" is the default.
+     [Bodo Moeller]
+
+  *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
+     [Bodo Moeller]
+
+  *) Install various scripts to $(OPENSSLDIR)/misc, not to
+     $(INSTALLTOP)/bin -- they shouldn't clutter directories
+     such as /usr/local/bin.
+     [Bodo Moeller]
+
+  *) "make linux-shared" to build shared libraries.
+     [Niels Poppe <niels@netbox.org>]
+
+  *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
+     [Ulf Möller]
+
+  *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
+     extension adding in x509 utility.
+     [Steve Henson]
+
+  *) Remove NOPROTO sections and error code comments.
+     [Ulf Möller]
+
+  *) Partial rewrite of the DEF file generator to now parse the ANSI
+     prototypes.
+     [Steve Henson]
+
+  *) New Configure options --prefix=DIR and --openssldir=DIR.
+     [Ulf Möller]
+
+  *) Complete rewrite of the error code script(s). It is all now handled
+     by one script at the top level which handles error code gathering,
+     header rewriting and C source file generation. It should be much better
+     than the old method: it now uses a modified version of Ulf's parser to
+     read the ANSI prototypes in all header files (thus the old K&R definitions
+     aren't needed for error creation any more) and do a better job of
+     translating function codes into names. The old 'ASN1 error code imbedded
+     in a comment' is no longer necessary and it doesn't use .err files which
+     have now been deleted. Also the error code call doesn't have to appear all
+     on one line (which resulted in some large lines...).
+     [Steve Henson]
+
+  *) Change #include filenames from <foo.h> to <openssl/foo.h>.
+     [Bodo Moeller]
+
+  *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
+     0 (which usually indicates a closed connection), but continue reading.
+     [Bodo Moeller]
+
+  *) Fix some race conditions.
+     [Bodo Moeller]
+
+  *) Add support for CRL distribution points extension. Add Certificate
+     Policies and CRL distribution points documentation.
+     [Steve Henson]
+
+  *) Move the autogenerated header file parts to crypto/opensslconf.h.
+     [Ulf Möller]
+
+  *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
+     8 of keying material. Merlin has also confirmed interop with this fix
+     between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
+     [Merlin Hughes <merlin@baltimore.ie>]
+
+  *) Fix lots of warnings.
+     [Richard Levitte <levitte@stacken.kth.se>]
+ 
+  *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
+     the directory spec didn't end with a LIST_SEPARATOR_CHAR.
+     [Richard Levitte <levitte@stacken.kth.se>]
+ 
+  *) Fix problems with sizeof(long) == 8.
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) Change functions to ANSI C.
+     [Ulf Möller]
+
+  *) Fix typos in error codes.
+     [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
+
+  *) Remove defunct assembler files from Configure.
+     [Ulf Möller]
+
+  *) SPARC v8 assembler BIGNUM implementation.
+     [Andy Polyakov <appro@fy.chalmers.se>]
+
+  *) Support for Certificate Policies extension: both print and set.
+     Various additions to support the r2i method this uses.
+     [Steve Henson]
+
+  *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
+     return a const string when you are expecting an allocated buffer.
+     [Ben Laurie]
+
+  *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
+     types DirectoryString and DisplayText.
+     [Steve Henson]
+
+  *) Add code to allow r2i extensions to access the configuration database,
+     add an LHASH database driver and add several ctx helper functions.
+     [Steve Henson]
+
+  *) Fix an evil bug in bn_expand2() which caused various BN functions to
+     fail when they extended the size of a BIGNUM.
+     [Steve Henson]
+
+  *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
+     support typesafe stack.
+     [Steve Henson]
+
+  *) Fix typo in SSL_[gs]et_options().
+     [Nils Frostberg <nils@medcom.se>]
+
+  *) Delete various functions and files that belonged to the (now obsolete)
+     old X509V3 handling code.
+     [Steve Henson]
+
+  *) New Configure option "rsaref".
+     [Ulf Möller]
+
+  *) Don't auto-generate pem.h.
+     [Bodo Moeller]
+
+  *) Introduce type-safe ASN.1 SETs.
+     [Ben Laurie]
+
+  *) Convert various additional casted stacks to type-safe STACK_OF() variants.
+     [Ben Laurie, Ralf S. Engelschall, Steve Henson]
+
+  *) Introduce type-safe STACKs. This will almost certainly break lots of code
+     that links with OpenSSL (well at least cause lots of warnings), but fear
+     not: the conversion is trivial, and it eliminates loads of evil casts. A
+     few STACKed things have been converted already. Feel free to convert more.
+     In the fullness of time, I'll do away with the STACK type altogether.
+     [Ben Laurie]
+
+  *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
+     specified in <certfile> by updating the entry in the index.txt file.
+     This way one no longer has to edit the index.txt file manually for
+     revoking a certificate. The -revoke option does the gory details now.
+     [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
+
+  *) Fix `openssl crl -noout -text' combination where `-noout' killed the
+     `-text' option at all and this way the `-noout -text' combination was
+     inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
+     [Ralf S. Engelschall]
+
+  *) Make sure a corresponding plain text error message exists for the
+     X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
+     verify callback function determined that a certificate was revoked.
+     [Ralf S. Engelschall]
+
+  *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
+     ciphers that were excluded, e.g. by -DNO_IDEA.  Also, test
+     all available cipers including rc5, which was forgotten until now.
+     In order to let the testing shell script know which algorithms
+     are available, a new (up to now undocumented) command
+     "openssl list-cipher-commands" is used.
+     [Bodo Moeller]
+
+  *) Bugfix: s_client occasionally would sleep in select() when
+     it should have checked SSL_pending() first.
+     [Bodo Moeller]
+
+  *) New functions DSA_do_sign and DSA_do_verify to provide access to
+     the raw DSA values prior to ASN.1 encoding.
+     [Ulf Möller]
+
+  *) Tweaks to Configure
+     [Niels Poppe <niels@netbox.org>]
+
+  *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
+     yet...
+     [Steve Henson]
+
+  *) New variables $(RANLIB) and $(PERL) in the Makefiles.
+     [Ulf Möller]
+
+  *) New config option to avoid instructions that are illegal on the 80386.
+     The default code is faster, but requires at least a 486.
+     [Ulf Möller]
+  
+  *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
+     SSL2_SERVER_VERSION (not used at all) macros, which are now the
+     same as SSL2_VERSION anyway.
+     [Bodo Moeller]
+
+  *) New "-showcerts" option for s_client.
+     [Bodo Moeller]
+
+  *) Still more PKCS#12 integration. Add pkcs12 application to openssl
+     application. Various cleanups and fixes.
+     [Steve Henson]
+
+  *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
+     modify error routines to work internally. Add error codes and PBE init
+     to library startup routines.
+     [Steve Henson]
+
+  *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
+     packing functions to asn1 and evp. Changed function names and error
+     codes along the way.
+     [Steve Henson]
+
+  *) PKCS12 integration: and so it begins... First of several patches to
+     slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
+     objects to objects.h
+     [Steve Henson]
+
+  *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
+     and display support for Thawte strong extranet extension.
+     [Steve Henson]
+
+  *) Add LinuxPPC support.
+     [Jeff Dubrule <igor@pobox.org>]
+
+  *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
+     bn_div_words in alpha.s.
+     [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
+
+  *) Make sure the RSA OAEP test is skipped under -DRSAref because
+     OAEP isn't supported when OpenSSL is built with RSAref.
+     [Ulf Moeller <ulf@fitug.de>]
+
+  *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h 
+     so they no longer are missing under -DNOPROTO. 
+     [Soren S. Jorvang <soren@t.dk>]
+
+
+ Changes between 0.9.1c and 0.9.2b  [22 Mar 1999]
+
+  *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
+     doesn't work when the session is reused. Coming soon!
+     [Ben Laurie]
+
+  *) Fix a security hole, that allows sessions to be reused in the wrong
+     context thus bypassing client cert protection! All software that uses
+     client certs and session caches in multiple contexts NEEDS PATCHING to
+     allow session reuse! A fuller solution is in the works.
+     [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
+
+  *) Some more source tree cleanups (removed obsolete files
+     crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
+     permission on "config" script to be executable) and a fix for the INSTALL
+     document.
+     [Ulf Moeller <ulf@fitug.de>]
+
+  *) Remove some legacy and erroneous uses of malloc, free instead of
+     Malloc, Free.
+     [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
+
+  *) Make rsa_oaep_test return non-zero on error.
+     [Ulf Moeller <ulf@fitug.de>]
+
+  *) Add support for native Solaris shared libraries. Configure
+     solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
+     if someone would make that last step automatic.
+     [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
+
+  *) ctx_size was not built with the right compiler during "make links". Fixed.
+     [Ben Laurie]
+
+  *) Change the meaning of 'ALL' in the cipher list. It now means "everything
+     except NULL ciphers". This means the default cipher list will no longer
+     enable NULL ciphers. They need to be specifically enabled e.g. with
+     the string "DEFAULT:eNULL".
+     [Steve Henson]
+
+  *) Fix to RSA private encryption routines: if p < q then it would
+     occasionally produce an invalid result. This will only happen with
+     externally generated keys because OpenSSL (and SSLeay) ensure p > q.
+     [Steve Henson]
+
+  *) Be less restrictive and allow also `perl util/perlpath.pl
+     /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
+     because this way one can also use an interpreter named `perl5' (which is
+     usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
+     installed as `perl').
+     [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
+
+  *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
+     [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
+
+  *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
+     advapi32.lib to Win32 build and change the pem test comparison
+     to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
+     suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
+     and crypto/des/ede_cbcm_enc.c.
+     [Steve Henson]
+
+  *) DES quad checksum was broken on big-endian architectures. Fixed.
+     [Ben Laurie]
+
+  *) Comment out two functions in bio.h that aren't implemented. Fix up the
+     Win32 test batch file so it (might) work again. The Win32 test batch file
+     is horrible: I feel ill....
+     [Steve Henson]
+
+  *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
+     in e_os.h. Audit of header files to check ANSI and non ANSI
+     sections: 10 functions were absent from non ANSI section and not exported
+     from Windows DLLs. Fixed up libeay.num for new functions.
+     [Steve Henson]
+
+  *) Make `openssl version' output lines consistent.
+     [Ralf S. Engelschall]
+
+  *) Fix Win32 symbol export lists for BIO functions: Added
+     BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
+     to ms/libeay{16,32}.def.
+     [Ralf S. Engelschall]
+
+  *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
+     fine under Unix and passes some trivial tests I've now added. But the
+     whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
+     added to make sure no one expects that this stuff really works in the
+     OpenSSL 0.9.2 release.  Additionally I've started to clean the XS sources
+     up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
+     openssl_bio.xs.
+     [Ralf S. Engelschall]
+
+  *) Fix the generation of two part addresses in perl.
+     [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
+
+  *) Add config entry for Linux on MIPS.
+     [John Tobey <jtobey@channel1.com>]
+
+  *) Make links whenever Configure is run, unless we are on Windoze.
+     [Ben Laurie]
+
+  *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
+     Currently only issuerAltName and AuthorityKeyIdentifier make any sense
+     in CRLs.
+     [Steve Henson]
+
+  *) Add a useful kludge to allow package maintainers to specify compiler and
+     other platforms details on the command line without having to patch the
+     Configure script everytime: One now can use ``perl Configure
+     <id>:<details>'', i.e. platform ids are allowed to have details appended
+     to them (separated by colons). This is treated as there would be a static
+     pre-configured entry in Configure's %table under key <id> with value
+     <details> and ``perl Configure <id>'' is called.  So, when you want to
+     perform a quick test-compile under FreeBSD 3.1 with pgcc and without
+     assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
+     now, which overrides the FreeBSD-elf entry on-the-fly.
+     [Ralf S. Engelschall]
+
+  *) Disable new TLS1 ciphersuites by default: they aren't official yet.
+     [Ben Laurie]
+
+  *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
+     on the `perl Configure ...' command line. This way one can compile
+     OpenSSL libraries with Position Independent Code (PIC) which is needed
+     for linking it into DSOs.
+     [Ralf S. Engelschall]
+
+  *) Remarkably, export ciphers were totally broken and no-one had noticed!
+     Fixed.
+     [Ben Laurie]
+
+  *) Cleaned up the LICENSE document: The official contact for any license
+     questions now is the OpenSSL core team under openssl-core@openssl.org.
+     And add a paragraph about the dual-license situation to make sure people
+     recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
+     to the OpenSSL toolkit.
+     [Ralf S. Engelschall]
+
+  *) General source tree makefile cleanups: Made `making xxx in yyy...'
+     display consistent in the source tree and replaced `/bin/rm' by `rm'.
+     Additionally cleaned up the `make links' target: Remove unnecessary
+     semicolons, subsequent redundant removes, inline point.sh into mklink.sh
+     to speed processing and no longer clutter the display with confusing
+     stuff. Instead only the actually done links are displayed.
+     [Ralf S. Engelschall]
+
+  *) Permit null encryption ciphersuites, used for authentication only. It used
+     to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
+     It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
+     encryption.
+     [Ben Laurie]
+
+  *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
+     signed attributes when verifying signatures (this would break them), 
+     the detached data encoding was wrong and public keys obtained using
+     X509_get_pubkey() weren't freed.
+     [Steve Henson]
+
+  *) Add text documentation for the BUFFER functions. Also added a work around
+     to a Win95 console bug. This was triggered by the password read stuff: the
+     last character typed gets carried over to the next fread(). If you were 
+     generating a new cert request using 'req' for example then the last
+     character of the passphrase would be CR which would then enter the first
+     field as blank.
+     [Steve Henson]
+
+  *) Added the new `Includes OpenSSL Cryptography Software' button as
+     doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
+     button and can be used by applications based on OpenSSL to show the
+     relationship to the OpenSSL project.  
+     [Ralf S. Engelschall]
+
+  *) Remove confusing variables in function signatures in files
+     ssl/ssl_lib.c and ssl/ssl.h.
+     [Lennart Bong <lob@kulthea.stacken.kth.se>]
+
+  *) Don't install bss_file.c under PREFIX/include/
+     [Lennart Bong <lob@kulthea.stacken.kth.se>]
+
+  *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
+     functions that return function pointers and has support for NT specific
+     stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
+     #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
+     unsigned to signed types: this was killing the Win32 compile.
+     [Steve Henson]
+
+  *) Add new certificate file to stack functions,
+     SSL_add_dir_cert_subjects_to_stack() and
+     SSL_add_file_cert_subjects_to_stack().  These largely supplant
+     SSL_load_client_CA_file(), and can be used to add multiple certs easily
+     to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
+     This means that Apache-SSL and similar packages don't have to mess around
+     to add as many CAs as they want to the preferred list.
+     [Ben Laurie]
+
+  *) Experiment with doxygen documentation. Currently only partially applied to
+     ssl/ssl_lib.c.
+     See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
+     openssl.doxy as the configuration file.
+     [Ben Laurie]
+  
+  *) Get rid of remaining C++-style comments which strict C compilers hate.
+     [Ralf S. Engelschall, pointed out by Carlos Amengual]
+
+  *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
+     compiled in by default: it has problems with large keys.
+     [Steve Henson]
+
+  *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
+     DH private keys and/or callback functions which directly correspond to
+     their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
+     is needed for applications which have to configure certificates on a
+     per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
+     (e.g. s_server). 
+        For the RSA certificate situation is makes no difference, but
+     for the DSA certificate situation this fixes the "no shared cipher"
+     problem where the OpenSSL cipher selection procedure failed because the
+     temporary keys were not overtaken from the context and the API provided
+     no way to reconfigure them. 
+        The new functions now let applications reconfigure the stuff and they
+     are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
+     SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback.  Additionally a new
+     non-public-API function ssl_cert_instantiate() is used as a helper
+     function and also to reduce code redundancy inside ssl_rsa.c.
+     [Ralf S. Engelschall]
+
+  *) Move s_server -dcert and -dkey options out of the undocumented feature
+     area because they are useful for the DSA situation and should be
+     recognized by the users.
+     [Ralf S. Engelschall]
+
+  *) Fix the cipher decision scheme for export ciphers: the export bits are
+     *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
+     SSL_EXP_MASK.  So, the original variable has to be used instead of the
+     already masked variable.
+     [Richard Levitte <levitte@stacken.kth.se>]
+
+  *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
+     [Richard Levitte <levitte@stacken.kth.se>]
+
+  *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
+     from `int' to `unsigned int' because it's a length and initialized by
+     EVP_DigestFinal() which expects an `unsigned int *'.
+     [Richard Levitte <levitte@stacken.kth.se>]
+
+  *) Don't hard-code path to Perl interpreter on shebang line of Configure
+     script. Instead use the usual Shell->Perl transition trick.
+     [Ralf S. Engelschall]
+
+  *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
+     (in addition to RSA certificates) to match the behaviour of `openssl dsa
+     -noout -modulus' as it's already the case for `openssl rsa -noout
+     -modulus'.  For RSA the -modulus is the real "modulus" while for DSA
+     currently the public key is printed (a decision which was already done by
+     `openssl dsa -modulus' in the past) which serves a similar purpose.
+     Additionally the NO_RSA no longer completely removes the whole -modulus
+     option; it now only avoids using the RSA stuff. Same applies to NO_DSA
+     now, too.
+     [Ralf S.  Engelschall]
+
+  *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
+     BIO. See the source (crypto/evp/bio_ok.c) for more info.
+     [Arne Ansper <arne@ats.cyber.ee>]
+
+  *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
+     to be added. Now both 'req' and 'ca' can use new objects defined in the
+     config file.
+     [Steve Henson]
+
+  *) Add cool BIO that does syslog (or event log on NT).
+     [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
+
+  *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
+     TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
+     TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
+     Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
+     [Ben Laurie]
+
+  *) Add preliminary config info for new extension code.
+     [Steve Henson]
+
+  *) Make RSA_NO_PADDING really use no padding.
+     [Ulf Moeller <ulf@fitug.de>]
+
+  *) Generate errors when private/public key check is done.
+     [Ben Laurie]
+
+  *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
+     for some CRL extensions and new objects added.
+     [Steve Henson]
+
+  *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
+     key usage extension and fuller support for authority key id.
+     [Steve Henson]
+
+  *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
+     padding method for RSA, which is recommended for new applications in PKCS
+     #1 v2.0 (RFC 2437, October 1998).
+     OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
+     foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
+     against Bleichbacher's attack on RSA.
+     [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
+      Ben Laurie]
+
+  *) Updates to the new SSL compression code
+     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
+
+  *) Fix so that the version number in the master secret, when passed
+     via RSA, checks that if TLS was proposed, but we roll back to SSLv3
+     (because the server will not accept higher), that the version number
+     is 0x03,0x01, not 0x03,0x00
+     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
+
+  *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
+     leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
+     in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
+     [Steve Henson]
+
+  *) Support for RAW extensions where an arbitrary extension can be
+     created by including its DER encoding. See apps/openssl.cnf for
+     an example.
+     [Steve Henson]
+
+  *) Make sure latest Perl versions don't interpret some generated C array
+     code as Perl array code in the crypto/err/err_genc.pl script.
+     [Lars Weber <3weber@informatik.uni-hamburg.de>]
+
+  *) Modify ms/do_ms.bat to not generate assembly language makefiles since
+     not many people have the assembler. Various Win32 compilation fixes and
+     update to the INSTALL.W32 file with (hopefully) more accurate Win32
+     build instructions.
+     [Steve Henson]
+
+  *) Modify configure script 'Configure' to automatically create crypto/date.h
+     file under Win32 and also build pem.h from pem.org. New script
+     util/mkfiles.pl to create the MINFO file on environments that can't do a
+     'make files': perl util/mkfiles.pl >MINFO should work.
+     [Steve Henson]
+
+  *) Major rework of DES function declarations, in the pursuit of correctness
+     and purity. As a result, many evil casts evaporated, and some weirdness,
+     too. You may find this causes warnings in your code. Zapping your evil
+     casts will probably fix them. Mostly.
+     [Ben Laurie]
+
+  *) Fix for a typo in asn1.h. Bug fix to object creation script
+     obj_dat.pl. It considered a zero in an object definition to mean
+     "end of object": none of the objects in objects.h have any zeros
+     so it wasn't spotted.
+     [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
+
+  *) Add support for Triple DES Cipher Block Chaining with Output Feedback
+     Masking (CBCM). In the absence of test vectors, the best I have been able
+     to do is check that the decrypt undoes the encrypt, so far. Send me test
+     vectors if you have them.
+     [Ben Laurie]
+
+  *) Correct calculation of key length for export ciphers (too much space was
+     allocated for null ciphers). This has not been tested!
+     [Ben Laurie]
+
+  *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
+     message is now correct (it understands "crypto" and "ssl" on its
+     command line). There is also now an "update" option. This will update
+     the util/ssleay.num and util/libeay.num files with any new functions.
+     If you do a: 
+     perl util/mkdef.pl crypto ssl update
+     it will update them.
+     [Steve Henson]
+
+  *) Overhauled the Perl interface (perl/*):
+     - ported BN stuff to OpenSSL's different BN library
+     - made the perl/ source tree CVS-aware
+     - renamed the package from SSLeay to OpenSSL (the files still contain
+       their history because I've copied them in the repository)
+     - removed obsolete files (the test scripts will be replaced
+       by better Test::Harness variants in the future)
+     [Ralf S. Engelschall]
+
+  *) First cut for a very conservative source tree cleanup:
+     1. merge various obsolete readme texts into doc/ssleay.txt
+     where we collect the old documents and readme texts.
+     2. remove the first part of files where I'm already sure that we no
+     longer need them because of three reasons: either they are just temporary
+     files which were left by Eric or they are preserved original files where
+     I've verified that the diff is also available in the CVS via "cvs diff
+     -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
+     the crypto/md/ stuff).
+     [Ralf S. Engelschall]
+
+  *) More extension code. Incomplete support for subject and issuer alt
+     name, issuer and authority key id. Change the i2v function parameters
+     and add an extra 'crl' parameter in the X509V3_CTX structure: guess
+     what that's for :-) Fix to ASN1 macro which messed up
+     IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
+     [Steve Henson]
+
+  *) Preliminary support for ENUMERATED type. This is largely copied from the
+     INTEGER code.
+     [Steve Henson]
+
+  *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
+     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
+
+  *) Make sure `make rehash' target really finds the `openssl' program.
+     [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
+
+  *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
+     like to hear about it if this slows down other processors.
+     [Ben Laurie]
+
+  *) Add CygWin32 platform information to Configure script.
+     [Alan Batie <batie@aahz.jf.intel.com>]
+
+  *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
+     [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
+  
+  *) New program nseq to manipulate netscape certificate sequences
+     [Steve Henson]
+
+  *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
+     few typos.
+     [Steve Henson]
+
+  *) Fixes to BN code.  Previously the default was to define BN_RECURSION
+     but the BN code had some problems that would cause failures when
+     doing certificate verification and some other functions.
+     [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
+
+  *) Add ASN1 and PEM code to support netscape certificate sequences.
+     [Steve Henson]
+
+  *) Add ASN1 and PEM code to support netscape certificate sequences.
+     [Steve Henson]
+
+  *) Add several PKIX and private extended key usage OIDs.
+     [Steve Henson]
+
+  *) Modify the 'ca' program to handle the new extension code. Modify
+     openssl.cnf for new extension format, add comments.
+     [Steve Henson]
+
+  *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
+     and add a sample to openssl.cnf so req -x509 now adds appropriate
+     CA extensions.
+     [Steve Henson]
+
+  *) Continued X509 V3 changes. Add to other makefiles, integrate with the
+     error code, add initial support to X509_print() and x509 application.
+     [Steve Henson]
+
+  *) Takes a deep breath and start adding X509 V3 extension support code. Add
+     files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
+     stuff is currently isolated and isn't even compiled yet.
+     [Steve Henson]
+
+  *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
+     ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
+     Removed the versions check from X509 routines when loading extensions:
+     this allows certain broken certificates that don't set the version
+     properly to be processed.
+     [Steve Henson]
+
+  *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
+     Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
+     can still be regenerated with "make depend".
+     [Ben Laurie]
+
+  *) Spelling mistake in C version of CAST-128.
+     [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
+
+  *) Changes to the error generation code. The perl script err-code.pl 
+     now reads in the old error codes and retains the old numbers, only
+     adding new ones if necessary. It also only changes the .err files if new
+     codes are added. The makefiles have been modified to only insert errors
+     when needed (to avoid needlessly modifying header files). This is done
+     by only inserting errors if the .err file is newer than the auto generated
+     C file. To rebuild all the error codes from scratch (the old behaviour)
+     either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
+     or delete all the .err files.
+     [Steve Henson]
+
+  *) CAST-128 was incorrectly implemented for short keys. The C version has
+     been fixed, but is untested. The assembler versions are also fixed, but
+     new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
+     to regenerate it if needed.
+     [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
+      Hagino <itojun@kame.net>]
+
+  *) File was opened incorrectly in randfile.c.
+     [Ulf Möller <ulf@fitug.de>]
+
+  *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
+     functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
+     GeneralizedTime. ASN1_TIME is the proper type used in certificates et
+     al: it's just almost always a UTCTime. Note this patch adds new error
+     codes so do a "make errors" if there are problems.
+     [Steve Henson]
+
+  *) Correct Linux 1 recognition in config.
+     [Ulf Möller <ulf@fitug.de>]
+
+  *) Remove pointless MD5 hash when using DSA keys in ca.
+     [Anonymous <nobody@replay.com>]
+
+  *) Generate an error if given an empty string as a cert directory. Also
+     generate an error if handed NULL (previously returned 0 to indicate an
+     error, but didn't set one).
+     [Ben Laurie, reported by Anonymous <nobody@replay.com>]
+
+  *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
+     [Ben Laurie]
+
+  *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
+     parameters. This was causing a warning which killed off the Win32 compile.
+     [Steve Henson]
+
+  *) Remove C++ style comments from crypto/bn/bn_local.h.
+     [Neil Costigan <neil.costigan@celocom.com>]
+
+  *) The function OBJ_txt2nid was broken. It was supposed to return a nid
+     based on a text string, looking up short and long names and finally
+     "dot" format. The "dot" format stuff didn't work. Added new function
+     OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote 
+     OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
+     OID is not part of the table.
+     [Steve Henson]
+
+  *) Add prototypes to X509 lookup/verify methods, fixing a bug in
+     X509_LOOKUP_by_alias().
+     [Ben Laurie]
+
+  *) Sort openssl functions by name.
+     [Ben Laurie]
+
+  *) Get the gendsa program working (hopefully) and add it to app list. Remove
+     encryption from sample DSA keys (in case anyone is interested the password
+     was "1234").
+     [Steve Henson]
+
+  *) Make _all_ *_free functions accept a NULL pointer.
+     [Frans Heymans <fheymans@isaserver.be>]
+
+  *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
+     NULL pointers.
+     [Anonymous <nobody@replay.com>]
+
+  *) s_server should send the CAfile as acceptable CAs, not its own cert.
+     [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
+
+  *) Don't blow it for numeric -newkey arguments to apps/req.
+     [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
+
+  *) Temp key "for export" tests were wrong in s3_srvr.c.
+     [Anonymous <nobody@replay.com>]
+
+  *) Add prototype for temp key callback functions
+     SSL_CTX_set_tmp_{rsa,dh}_callback().
+     [Ben Laurie]
+
+  *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
+     DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
+     [Steve Henson]
+
+  *) X509_name_add_entry() freed the wrong thing after an error.
+     [Arne Ansper <arne@ats.cyber.ee>]
+
+  *) rsa_eay.c would attempt to free a NULL context.
+     [Arne Ansper <arne@ats.cyber.ee>]
+
+  *) BIO_s_socket() had a broken should_retry() on Windoze.
+     [Arne Ansper <arne@ats.cyber.ee>]
+
+  *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
+     [Arne Ansper <arne@ats.cyber.ee>]
+
+  *) Make sure the already existing X509_STORE->depth variable is initialized
+     in X509_STORE_new(), but document the fact that this variable is still
+     unused in the certificate verification process.
+     [Ralf S. Engelschall]
+
+  *) Fix the various library and apps files to free up pkeys obtained from
+     X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
+     [Steve Henson]
+
+  *) Fix reference counting in X509_PUBKEY_get(). This makes
+     demos/maurice/example2.c work, amongst others, probably.
+     [Steve Henson and Ben Laurie]
+
+  *) First cut of a cleanup for apps/. First the `ssleay' program is now named
+     `openssl' and second, the shortcut symlinks for the `openssl <command>'
+     are no longer created. This way we have a single and consistent command
+     line interface `openssl <command>', similar to `cvs <command>'.
+     [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
+
+  *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
+     BIT STRING wrapper always have zero unused bits.
+     [Steve Henson]
+
+  *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
+     [Steve Henson]
+
+  *) Make the top-level INSTALL documentation easier to understand.
+     [Paul Sutton]
+
+  *) Makefiles updated to exit if an error occurs in a sub-directory
+     make (including if user presses ^C) [Paul Sutton]
+
+  *) Make Montgomery context stuff explicit in RSA data structure.
+     [Ben Laurie]
+
+  *) Fix build order of pem and err to allow for generated pem.h.
+     [Ben Laurie]
+
+  *) Fix renumbering bug in X509_NAME_delete_entry().
+     [Ben Laurie]
+
+  *) Enhanced the err-ins.pl script so it makes the error library number 
+     global and can add a library name. This is needed for external ASN1 and
+     other error libraries.
+     [Steve Henson]
+
+  *) Fixed sk_insert which never worked properly.
+     [Steve Henson]
+
+  *) Fix ASN1 macros so they can handle indefinite length constructed 
+     EXPLICIT tags. Some non standard certificates use these: they can now
+     be read in.
+     [Steve Henson]
+
+  *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
+     into a single doc/ssleay.txt bundle. This way the information is still
+     preserved but no longer messes up this directory. Now it's new room for
+     the new set of documentation files.
+     [Ralf S. Engelschall]
+
+  *) SETs were incorrectly DER encoded. This was a major pain, because they
+     shared code with SEQUENCEs, which aren't coded the same. This means that
+     almost everything to do with SETs or SEQUENCEs has either changed name or
+     number of arguments.
+     [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
+
+  *) Fix test data to work with the above.
+     [Ben Laurie]
+
+  *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
+     was already fixed by Eric for 0.9.1 it seems.
+     [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
+
+  *) Autodetect FreeBSD3.
+     [Ben Laurie]
+
+  *) Fix various bugs in Configure. This affects the following platforms:
+     nextstep
+     ncr-scde
+     unixware-2.0
+     unixware-2.0-pentium
+     sco5-cc.
+     [Ben Laurie]
+
+  *) Eliminate generated files from CVS. Reorder tests to regenerate files
+     before they are needed.
+     [Ben Laurie]
+
+  *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
+     [Ben Laurie]
+
+
+ Changes between 0.9.1b and 0.9.1c  [23-Dec-1998]
+
+  *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and 
+     changed SSLeay to OpenSSL in version strings.
+     [Ralf S. Engelschall]
+  
+  *) Some fixups to the top-level documents.
+     [Paul Sutton]
+
+  *) Fixed the nasty bug where rsaref.h was not found under compile-time
+     because the symlink to include/ was missing.
+     [Ralf S. Engelschall]
+
+  *) Incorporated the popular no-RSA/DSA-only patches 
+     which allow to compile a RSA-free SSLeay.
+     [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
+
+  *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
+     when "ssleay" is still not found.
+     [Ralf S. Engelschall]
+
+  *) Added more platforms to Configure: Cray T3E, HPUX 11, 
+     [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
+
+  *) Updated the README file.
+     [Ralf S. Engelschall]
+
+  *) Added various .cvsignore files in the CVS repository subdirs
+     to make a "cvs update" really silent.
+     [Ralf S. Engelschall]
+
+  *) Recompiled the error-definition header files and added
+     missing symbols to the Win32 linker tables.
+     [Ralf S. Engelschall]
+
+  *) Cleaned up the top-level documents;
+     o new files: CHANGES and LICENSE
+     o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay 
+     o merged COPYRIGHT into LICENSE
+     o removed obsolete TODO file
+     o renamed MICROSOFT to INSTALL.W32
+     [Ralf S. Engelschall]
+
+  *) Removed dummy files from the 0.9.1b source tree: 
+     crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
+     crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
+     crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
+     crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
+     util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
+     [Ralf S. Engelschall]
+
+  *) Added various platform portability fixes.
+     [Mark J. Cox]
+
+  *) The Genesis of the OpenSSL rpject:
+     We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
+     Young and Tim J. Hudson created while they were working for C2Net until
+     summer 1998.
+     [The OpenSSL Project]
+ 
+
+ Changes between 0.9.0b and 0.9.1b  [not released]
+
+  *) Updated a few CA certificates under certs/
+     [Eric A. Young]
+
+  *) Changed some BIGNUM api stuff.
+     [Eric A. Young]
+
+  *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD, 
+     DGUX x86, Linux Alpha, etc.
+     [Eric A. Young]
+
+  *) New COMP library [crypto/comp/] for SSL Record Layer Compression: 
+     RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
+     available).
+     [Eric A. Young]
+
+  *) Add -strparse option to asn1pars program which parses nested 
+     binary structures

+     [Eric A. Young]
+
+  *) Added PLATFORM define which is the id given to Configure.
+     [Eric A. Young]
+
+  *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
+     [Eric A. Young]
+
+  *) Extended the ASN.1 parser routines.
+     [Eric A. Young]

+
+  *) Added a BN_CTX to the BN library.
+     [Eric A. Young]
+
+  *) Fixed the weak key values in DES library
+     [Eric A. Young]
+
+  *) Changed API in EVP library for cipher aliases.
+     [Eric A. Young]
+
+  *) Added support for RC2/64bit cipher.
+     [Eric A. Young]
+
+  *) Converted the lhash library to the crypto/mem.c functions.

+     [Eric A. Young]
+
+  *) Now Fortezza is denied in the authentication phase because
+     this is key exchange mechanism is not supported by SSLeay at all.
+     [Eric A. Young]
