2017-11-11implement compress option `reduce_funcs` (#2466)...- inline single-use function declarations as expressions when permissible - depend on `reduce_vars` - enabled by default - disable for speed critical code fixes #2464Alex Lam S.L

2017-07-29improve `mangle.properties` (#2261)...- include dead code when `keep_quoted` - unify `keep_quoted` & `reserved` - make `test/run-tests.js` consistent with `minify()` fixes #2256Alex Lam S.L

2017-07-06inline property access of object literal (#2209)...- only if property value is side-effect-free - guard by `unsafe` fixes #2208Alex Lam S.L

2017-04-15unify CLI & API under `minify()` (#1811)...- rename `screw_ie8` to `ie8` - rename `mangle.except` to `mangle.reserved` - rename `mangle.properties.ignore_quoted` to `mangle.properties.keep_quoted` - compact `sourceMap` options - more stringent verification on input `options` - toplevel shorthands - `ie8` - `keep_fnames` - `toplevel` - `warnings` - support arrays and unquoted string values on CLI - drop `fromString` from `minify()` - `minify()` no longer handles any `fs` operations - unify order of operations for `mangle_properties()` on CLI & API - `bin/uglifyjs` used to `mangle_properties()` before even `Compressor` - `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()` - both will now do `Compressor`, `mangle_names()` then `mangle_properties()` - `options.parse` / `--parse` for parser options beyond `bare_returns` - add `mangle.properties.builtins` to disable built-in reserved list - disable with `--mangle-props builtins` on CLI - `warnings` now off by default - add `--warn` and `--verbose` on CLI - drop `--enclose` - drop `--export-all` - drop `--reserved-file` - use `--mangle reserved` instead - drop `--reserve-domprops` - enabled by default, disable with `--mangle-props domprops` - drop `--prefix` - use `--source-map base` instead - drop `--lint` - remove `bin/extract-props.js` - limit exposure of internal APIs - update documentations closes #96 closes #102 closes #136 closes #166 closes #243 closes #254 closes #261 closes #311 closes #700 closes #748 closes #912 closes #1072 closes #1366 fixes #101 fixes #123 fixes #124 fixes #263 fixes #379 fixes #419 fixes #423 fixes #461 fixes #465 fixes #576 fixes #737 fixes #772 fixes #958 fixes #1036 fixes #1142 fixes #1175 fixes #1220 fixes #1223 fixes #1280 fixes #1359 fixes #1368Alex Lam S.L
2017-04-01improve compression of undefined, NaN & Infinitiy (#1748)...- migrate transformation logic from `OutputStream` to `Compressor` - always turn `undefined` into `void 0` (unless `unsafe`) - always keep `NaN` except when avoiding local variable redefinition - introduce `keep_infinity` to suppress `1/0` transform, except when avoiding local variable redefinition supersedes #1723 fixes #1730Alex Lam S.L
2017-03-29output optimal representations of NaN & Infinity (#1723)...- move these optimisations out from `Compressor` to `OutputStream` - fixes behaviour inconsistency when running uglified code from global or module levels due to redefinitionAlex Lam S.L
2017-02-21introduce `unsafe_proto`...- `Array.prototype.slice` => `[].slice` closes #1491 alexlamsl
2017-01-26augment evaluate to extract within objects (#1425)...- gated by `unsafe` - replaces previous optimisation specific to String.length - "123"[0] => 1 - [1, 2, 3][0] => 1 - [1, 2, 3].length => 3 - does not apply to objects with overridden prototype functionsAlex Lam S.L
2016-11-29Add --mangle-props-debug and fix --mangle-props=unquoted collision...Patch by @AshleyScirra Based on: PR #1316 Renamed the CLI debug option to --mangle-props-debug Fixes: #1321 name collision in --mangle-props=unquoted Ashley (Scirra)
2016-08-14Fix --mangle-props and --mangle-props=unquoted...Fixes: #1247 Fix --mangle-props and --name-cache inconsistency. AST_Dot and AST_Sub properties are now mangled by --mangle-props without regard to being used in an assignment statement. Note: if --mangle-props is used then *all* javascript files used must be uglified with the same mangle options. Fix the ignore_quoted=true mangle option, also known as `--mangle-props=unquoted`. If a given property is quoted anywhere it will not be mangled in any quoted or non-quoted context. kzc

2016-06-30Enable --screw-ie8 by default....catch identifier is mangled correctly for ES5 standards-compliant JS engines by default. Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled. To support non-standard ie8 javascript use: uglifyjs --support-ie8 kzc
2016-06-19Respect quote style in object literals...The option added in fbbaa42ee55a7f753f7cab9b1a905ccf73cf26d5 wasn't being respected inside object literals, so quoted property names would still be stripped out with this option. This is mostly a corner-case, but useful when the output is passed to something like the Closure compiler, where quoted property names can be used to prevent mangling. Shrey Banga
