| 2017-03-08 | only run benchmark & jetstream on CI (#1571) | Alex Lam S.L |
| 2017-03-08 | plan B for IE8 do-while semi-colon fix (#1572)...- omitting trailing semi-colon in do-while breaks non-browser parser, e.g. uglify-js 1.x - trailing semi-colon only breaks IE8 if followed by `else` or `while` - always use braces in do-while body to workaround 2nd case with no size loss in compression fixes #1568 | Alex Lam S.L |
| 2017-03-08 | fix return from recursive IIFE (#1570)...`side-effects` did not account for IIFEs being able to reference itself thus making its return value potentially significant | Alex Lam S.L |
| 2017-03-07 | include benchmark.js in test suite (#1564)...- report file sizes and overall run time - exit with non-zero code upon error | Alex Lam S.L |
| 2017-03-07 | fix deep cloning of labels (#1565)...`AST_Label.references` get `.initialize()` to `[]` every time after `.clone()` So walk down the tree to pick up the cloned `AST_LoopControl` pieces and put it back together. | Alex Lam S.L |
| 2017-03-07 | transform function calls to IIFEs (#1560)...- expose function body to call sites for potential optimisations - suppress substitution of variable used within `AST_Defun` | Alex Lam S.L |
| 2017-03-07 | avoid substitution of global variables (#1557)...- unless `toplevel` is enabled - global `const` works as before | Alex Lam S.L |
| 2017-03-07 | collapse_vars: do not replace a constant in loop condition or init (#1562) | kzc |
| 2017-03-06 | suppress semicolons after do/while (#1556)...- unless both `beautify` & `screw-ie8` are enabled - deprecate workaround for if-do-while-else fixes #186 | Alex Lam S.L |
| 2017-03-05 | fixup for #1553 (#1555)...- `++a` is the one that is foldable - transform `a++` into `++a` for better optimisation | Alex Lam S.L |
| 2017-03-05 | collapse assignment with adjacent subsequent usage (#1553)...- consolidate `cascade` optimisations - support ++/-- postfixes - remove redundant optimisation identified in #1460 fixes #368 | Alex Lam S.L |
| 2017-03-05 | handle variable declaration within catch blocks (#1546)...accounts for IE8- scoping | Alex Lam S.L |
| 2017-03-05 | improve `unsafe` on undefined (#1548)...`unsafe` turns undefined keyword into a variable of the same name if found, but that interferes with other related optimisations. Keep track of such transformations to ensure zero information loss in the process. | Alex Lam S.L |
| 2017-03-05 | stay safe with constants in IE8- (#1547)...- `undefined` etc. can be redefined at top-level for IE8-, so disable related optimisations - fixed `--support-ie8` catch mangle bug | Alex Lam S.L |
| 2017-03-05 | fix handling of shebang and preamble (#1545)...fixes #1332 | Alex Lam S.L |
| 2017-03-05 | fix a corner case in #1530 (#1552) | Alex Lam S.L |
| 2017-03-03 | process code with implicit return statement (#1522)...Bookmarklet for instance implicitedly assumes a "completion value" without using `return`. The `expression` option now supports such use cases. Optimisations on IIFEs also enhanced. fixes #354 fixes #543 fixes #625 fixes #628 fixes #640 closes #1293 | Alex Lam S.L |
| 2017-03-03 | compress numerical expressions (#1513)...safe operations - `a === b` => `a == b` - `a + -b` => `a - b` - `-a + b` => `b - a` - `a+ +b` => `+b+a` associative operations (bit-wise operations are safe, otherwise `unsafe_math`) - `a + (b + c)` => `(a + b) + c` - `(n + 2) + 3` => `5 + n` - `(2 * n) * 3` => `6 * n` - `(a | 1) | (2 | d)` => `(3 | a) | b` fixes #412 | Alex Lam S.L |
| 2017-03-03 | fix chained assignment with `unused` (#1540)...When #1450 optimises `a=b=42`, it stops after the first variable even if both are unused. fixes #1539 | Alex Lam S.L |
| 2017-03-03 | collapse_vars should not replace constant in for-in init section (#1538)...fixes #1537 | kzc |
| 2017-03-03 | properly cover all cases of for-in loop variables (#1536) | Alex Lam S.L |
| 2017-03-03 | fix reference marking in for-in loops (#1535)...fixes #1533 | Alex Lam S.L |

| 2017-03-02 | optimize trivial IIFEs returning constants (#1530) | kzc |
| 2017-03-02 | trim unused invocation parameters (#1526) | Alex Lam S.L |
| 2017-03-02 | minor improvement to string optimisation (#1514)...- "" + "a" => "a" - "" + a + "b" => a + "b" - "a" + "" => "a" (improving on #45) | Alex Lam S.L |
| 2017-03-02 | fix corner cases in `reduce_vars` (#1524)...Avoid variable substitution in the following cases: - use of variable before declaration - declaration within conditional code blocks - declaration within loop body fixes #1518 fixes #1525 | Alex Lam S.L |
| 2017-03-01 | invert `reduce_vars` tracking flag (#1519)...Modules like webpack and grunt-contrib-uglify still uses `ast.transform(compressor)` before `Compressor.compress(ast)` was introduced. Workaround this compatibility issue by deactivating `reduce_vars` in such case. Also fix use case with omitted `options` when calling `Compressor()`. fixes #1516 | Alex Lam S.L |
| 2017-03-01 | fix `evaluate` on object getter & setter (#1515) | Alex Lam S.L |

| 2017-02-25 | allow --in-source-map inline (#1490)...- limited to one input file (or `stdin`) - only works with built-in parser fixes #520 | Alex Lam S.L |
| 2017-02-24 | enable `collapse_vars` & `reduce_vars` by default...- fix corner cases in `const` optimisation - deprecate `/*@const*/` fixes #1497 closes #1498 | alexlamsl |
| 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 | Fix: AST_Accessor missing start / end tokens...fixes #1492 closes #1493 | Ondřej Španěl |
| 2017-02-21 | fix `pure_funcs` & improve `side_effects`...- only drops side-effect-free arguments - drop side-effect-free parts with discarded value from `AST_Seq` & `AST_SimpleStatement` closes #1494 | alexlamsl |
| 2017-02-21 | clean up `max_line_len`...- never exceed specified limit - otherwise warning is shown - enabled only for final output closes #1496 | alexlamsl |
| 2017-02-21 | introduce `unsafe_proto`...- `Array.prototype.slice` => `[].slice` closes #1491 | alexlamsl |
| 2017-02-21 | remove extraneous spaces between ++/+/--/-...fixes #1377 closes #1488 | alexlamsl |
| 2017-02-21 | Add .gitattributes to checkout lf eol style...closes #1487 | Anthony Van de Gejuchte |
| 2017-02-21 | improve `--beautify bracketize`...reduce whitespaces from if-else statements fixes #1482 closes #1483 | alexlamsl |
| 2017-02-21 | add benchmark & JetStream tests...- `test/benchmark.js` measures performance - `test/jetstream.js` verifies correctness - configurable mangle/compress/output options closes #1479 | alexlamsl |
| 2017-02-21 | enhance `global_defs`...- support arrays, objects & AST_Node - support `"a.b":1` on both cli & API - emit warning if variable is modified - override top-level variables fixes #1416 closes #1198 closes #1469 | alexlamsl |
| 2017-02-21 | evaluate AST_SymbolRef as parameter...fix invalid boolean conversion now exposed in `make_node_from_constant()` closes #1477 | alexlamsl |

| 2017-02-21 | improve keep_fargs & keep_fnames...- utilise in_use_ids instead of unreferenced() - drop_unused now up-to-date for subsequent passes closes #1476 | alexlamsl |
| 2017-02-21 | fix duplicated test names...previously test cases with the same name would be skipped except for the last one `test/run-test.js` will now report duplicated names as errors closes #1461 | alexlamsl |
| 2017-02-21 | smarter const replacement taking name length into account...closes #1459 | kzc |
| 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 closes #1451 | alexlamsl |
