| 2017-12-02 | more tests for #2535 (#2551) | Alex Lam S.L |
| 2017-12-01 | improve boolean compression (#2548)...fixes #2535 | Alex Lam S.L |
| 2017-11-11 | implement compress option `reduce_funcs` (#2466)...- inline single-use function declarations as expressions when permissible
- depend on `reduce_vars`
- enabled by default
- disable for speed critical code
fixes #2464 | Alex Lam S.L |
| 2017-10-29 | enhance `properties` (#2412)...- trim array items only if `side_effects`
- extend to non-identifier properties | Alex Lam S.L |
| 2017-10-26 | compress self comparisons (#2398) | Alex Lam S.L |
| 2017-10-22 | safer `properties` transform (#2391)...`{ a: x, b: y }.a` => `[ x, y ][0]`
- `x` cannot be function containing `this`
`[ x, y, z ][1]` => `(x, z, y)`
- only if `z` is side-effect-free | Alex Lam S.L |
| 2017-10-09 | perform `reduce_vars` on safe literals (#2351)...- constant expression
- single reference
- same scope
- not across loop body | Alex Lam S.L |
| 2017-07-14 | fix `unsafe` `evaluate` of `Object` static methods (#2232)...fixes #2231 | Alex Lam S.L |
| 2017-07-07 | inlining of static methods & constants (#2211)...- guard by `unsafe`
- support `Array`, `Math`, `Number`, `Object` & `String`
fixes #2207 | Alex Lam S.L |
| 2017-07-06 | inline property access of object literal (#2209)...- only if property value is side-effect-free
- guard by `unsafe`
fixes #2208 | Alex Lam S.L |
| 2017-06-06 | implement function inlining (#2053)...- empty body
- single `AST_Return`
- single `AST_SimpleStatement`
- avoid `/*#__PURE__*/`
Miscellaneous
- enhance single-use function substitution
fixes #281 | Alex Lam S.L |
| 2017-06-01 | whitelist `unsafe` `evaluate` candidates (#2039)...- all arguments may accept constant values
- return constant value
- free of side effects
- available & identical across locales and runtime environments | Alex Lam S.L |
| 2017-06-01 | enhance `unsafe` `evaluate` (#2037) | Alex Lam S.L |
| 2017-05-19 | introduce `unsafe_regexp` (#1970)...fixes #1964 | Alex Lam S.L |
| 2017-05-12 | remove support for `const` (#1910)...As this is not part of ES5. | Alex Lam S.L |
| 2017-04-12 | convert `AST_Seq` from binary tree to array (#1460)...- rename `AST_Seq` to `AST_Sequence`
- raise default sequences_limit from 200 to 800 | Alex Lam S.L |
| 2017-04-09 | fix LHS cases for NaN & friends (#1804)...`Infinity = beyond` should not become `1/0 = beyond` | Alex Lam S.L |
| 2017-04-08 | fix `delete` corner cases (#1799)...- assignment
- boolean
- conditional
- sequence | Alex Lam S.L |
| 2017-04-07 | fix corner cases with `delete` (#1796)...`delete Infinity` returns `false` where as `delete (1/0)` returns `true` | Alex Lam S.L |
| 2017-04-02 | avoid confusion of `NaN` & `Infinity` with `catch` symbol of the same name (#......fixes #1760
fixes #1761 | Alex Lam S.L |
| 2017-04-01 | improve compression of undefined, NaN & Infinitiy (#1748)...- migrate transformation logic from `OutputStream` to `Compressor`
- always turn `undefined` into `void 0` (unless `unsafe`)
- always keep `NaN` except when avoiding local variable redefinition
- introduce `keep_infinity` to suppress `1/0` transform, except when avoiding local variable redefinition
supersedes #1723
fixes #1730 | Alex Lam S.L |
| 2017-03-29 | output optimal representations of NaN & Infinity (#1723)...- move these optimisations out from `Compressor` to `OutputStream`
- fixes behaviour inconsistency when running uglified code from global or module levels due to redefinition | Alex Lam S.L |
| 2017-03-24 | fix cascade of `evaluate` optimisation (#1654)...Operator has changed, so break out from rest of the rules.
fixes #1649 | Alex Lam S.L |
| 2017-03-19 | make `expect_stdout` work on Node.js 0.12 (#1623)...That particular version of Node.js has messed up error messages, so provide a version-specific workaround.
Also fixed an formatting issue which would cause `expect_stdout` to fail if error message contains excerpts of input.
Apply `expect_stdout` to more applicable tests. | Alex Lam S.L |
| 2017-03-19 | transform String.charAt() to index access (#1620)...Guarded by `unsafe` as `charAt()` can be overridden. | 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.

closes #1293 | Alex Lam S.L |
| 2017-03-02 | trim unused invocation parameters (#1526) | Alex Lam S.L |
| 2017-03-01 | fix `evaluate` on object getter & setter (#1515) | Alex Lam S.L |
| 2017-02-28 | warn & drop `#__PURE__` iff IIFE is dropped (#1511)...- consolidate `side-effects` optimisations
- improve string `+` optimisation
- enhance literal & `conditionals` optimisations | Alex Lam S.L |
| 2017-02-26 | consolidate `evaluate` & `reduce_vars` (#1505)...- improve marking efficiency
- apply smarter `const` replacement to `var`
fixes #1501 | 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

| 2017-02-21 | evaluate AST_SymbolRef as parameter...fix invalid boolean conversion now exposed in `make_node_from_constant()`
closes #1477
| alexlamsl |
| 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 |
| 2016-05-24 | Completely allow evaluating -0 | Richard van Velzen |
| 2016-05-17 | Never produce -0 when evaluating expressions (like -"")...Fix for #1085. The major case was already there, but more expressions can result in -0.
| Richard van Velzen |
