| 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
- 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

closes #1446
| alexlamsl |

| 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 |
| 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 | 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.
fixes #1299

| 2016-08-17 | Fix negate_iife transform to return a correct tree for nested IIFEs...Fix for #1256, partially reverts d854523783b4

| 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.

| 2016-07-03 | Don't convert all strings to directives from moz-ast | Anthony Van de Gejuchte |
| 2016-07-01 | Change the default sequences limit to 200 to speed up compress....Has little or no impact on minification size in the majority of
cases but can speed up rollup builds significantly.
This sequences change also has the beneficial side effect of avoiding
"stack size exceeded" errors on very large input files.
The user is free to alter the sequences limit if they are so inclined.
The previous sequences limit was 2000. 20 is often sufficient.

| 2016-07-01 | Allow sequences maximum length to be user configurable. | kzc |
| 2016-06-30 | Various LineTerminator changes...* Escaped newlines should also produce SyntaxError
* Fix multiline comment parsing and add tests
* Adapt makePredicate to handle \u2028 and \u2029
* Move up nlb check in regex so it's checked before any escape handling
* Change error messages to conform ecma standard
* Find_eol not recornizing \u2028 and \u2029 as line terminator
* Remove \u180e as it is removed in unicode 6.3.0 from the category zs
| Anthony Van de Gejuchte |
| 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
