| 2017-02-21 | clean up `negate_iife`...- remove extra tree scanning phase for `negate_iife`
- `negate_iife` now only deals with the narrowest form, i.e. IIFE sitting directly under `AST_SimpleStatement`
- `booleans`, `conditionals` etc. will now take care the rest via more accurate accounting
- `a(); void b();` => `a(); b();`
fixes #1288

- ["a", "b"].join(undefined) => "a,b"
- [a + "b", c].join("") => a + "b" + c
closes #1453

| 2017-02-21 | drop unused: toplevel, assign-only...- assign statement does not count towards variable usage by default

| 2017-01-26 | update test (#1441)...improved reduce_vars & binary operands produce more optimal results | Alex Lam S.L |
| 2017-01-26 | fix mangling collision with keep_fnames (#1431)...* fix mangling collision with keep_fnames
fixes #1423
* pass mangle options to figure_out_scope()
bring command-line in line with minify()
| Alex Lam S.L |
| 2017-01-26 | optimise binary operands with evaluate() (#1427)...- remove call to evaluate() in is_constant() and let nested optimize() does its job instead
- reject RegExp in is_constant() and remove special case logic under collapse_vars
- operands to conditionals optimisation are now always evaluate()-ed
- throw error in constant_value() instead of returning undefined to catch possible bugs, similar to make_node_from_constant()
- optimise binary boolean operators under `evaluate` instead of `conditionals` | Alex Lam S.L |
| 2017-01-26 | augment 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 functions | Alex Lam S.L |

| 2016-08-14 | Fix --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.

| 2016-06-30 | Enable --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 |
| 2016-06-30 | Move OctalEscapeSequence to read_escape_char...This should simplify and improve implementation, make it easier to
implement template strings, and keep master a bit more in sync with
harmony.
Previous implementation wasn't broken, though the loop gave me the
impression it could read infinite numbers and annoyed me a bit. It was
also slightly unnecessary because the lookup involved only 3 characters.

| 2016-06-21 | Don't replace undefined, NaN and Infinity within with scope | kzc |
| 2016-06-19 | Respect 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.
