| 2017-02-24 | Merge pull request #1485 from alexlamsl/merge-2.8.0...2.8.0 staging | Alex Lam S.L |
| 2017-02-24 | enable `collapse_vars` & `reduce_vars` by default...- fix corner cases in `const` optimisation

| 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.

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

- `a(); void b();` => `a(); b();`

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

- `top_retain` to whitelist top-level exceptions

* 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 |
| 2017-01-19 | add missing LHS cases which global_defs should avoid | alexlamsl |
| 2016-11-29 | Generate source map data from normalized files...If using `inSourceMap` this fix will ensure the copying of `sourcesContent` is based on potentially normalized `sources` values (https://github.com/mozilla/source-map/blob/master/lib/source-map-consumer.js#L304-L309).
For example `normalize` (https://github.com/mozilla/source-map/blob/master/lib/util.js#L80-L123) will rewrite `./dist/mySource.js` to `dist/mySource.js` in the target `_sources` of the `SourceMapConsumer`. As a result `orig_map.sourceContentFor(source, true);` would return `null` since the orginal `source` was no longer available in the consumer. By using the keys generating from the `SourceMapConsumer.constructor` consistency is ensured.

| 2016-11-29 | Add --mangle-props-debug and fix --mangle-props=unquoted collision...Patch by @AshleyScirra
Based on: PR #1316

| 2016-11-29 | Do not overwrite options.comments + cleanup | Anthony Van de Gejuchte |
| 2016-10-23 | Don't filter shebangs when using the 'some' comment filter...Also clarify documentation a bit more about using regexp as filter
| Anthony Van de Gejuchte |
| 2016-10-23 | fix uses_arguments handling (broken since 6605d1578351)...Using the symbol declaration tracking of UglifyJS doesn't make sense here
anyway, `arguments` always comes from something in the current scope.

| 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.
