| 2017-02-21 | Support marking a call as pure...A function call or IIFE with an immediately preceding comment
containing `@__PURE__` or `#__PURE__` is deemed to be a
side-effect-free pure function call and can potentially be
dropped.
Depends on `side_effects` option.
`[#@]__PURE__` hint will be removed from comment when pure
call is dropped.
fixes #1261
closes #1448

| kzc |
| 2017-02-21 | clean up `negate_iife`...- remove extra tree scanning phase for `negate_iife`

- [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
- only works with assignments on the same scope level as declaration
- can be disabled with `unused` set to "keep_assign"
- `toplevel` to drop unused top-level variables and/or functions
- `top_retain` to whitelist top-level exceptions
closes #1450

| 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 |

| 2016-08-17 | Fix negate_iife transform to return a correct tree for nested IIFEs...Fix for #1256, partially reverts d854523783b4
| Richard van Velzen |
| 2016-08-17 | Fix negate_iife regression #1254 | kzc |
| 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.
