| 2017-05-14 | fix bugs with getter/setter (#1926) | Alex Lam S.L | |
| - `reduce_vars` - `side_effects` - property access for object - `AST_SymbolAccessor` as key names enhance `test/ufuzz.js` - add object getter & setter - property assignment to setter - avoid infinite recursion in setter - fix & adjust assignment operators - 50% `=` - 25% `+=` - 2.5% each for the rest - avoid "Invalid array length" - fix `console.log()` - bypass getter - curb recursive reference - deprecate `-E`, always report runtime errors | |||
| 2017-05-12 | remove support for `const` (#1910) | Alex Lam S.L | |
| As this is not part of ES5. | |||

| 2017-04-17 | fix `reduce_vars` on boolean binary expressions (#1819) | Alex Lam S.L | |
| Side effects of `&&` and `||` have not mattered until #1814, which takes assignment expressions into account. | |||
| 2017-04-17 | compress duplicated variable definitions (#1817) | Alex Lam S.L | |
| These are surprisingly common, as people reuse the same variable name within loops or switch branches. | |||
| 2017-04-17 | fix `reduce_vars` within try-block (#1818) | Alex Lam S.L | |
| Possible partial execution due to exceptions. | |||
| 2017-04-17 | enhance `reduce_vars` (#1814) | Alex Lam S.L | |
| - allow immediate assignment after declaration of variable - relax modification rule for immutable value - fix order of visit for TreeWalker - remove extraneous code | |||
| 2017-04-16 | fix variable substitution (#1816) | Alex Lam S.L | |
| - let `collapse_vars` take care of value containing any symbols - improve overhead accounting | |||
| 2017-04-07 | introduce "strict" to `pure_getters` (#1795) | Alex Lam S.L | |
| 2017-04-07 | fix `reduce_vars` on catch variable (#1794) | Alex Lam S.L | |
| Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`. Also fixed recursive assignment in variable definition. | |||
| 2017-04-07 | fix incorrect context in variable substitution (#1791) | Alex Lam S.L | |
| `AST_Node.optimize()` is context-aware, so don't cache its results to be used elsewhere. Also fixed a few cases of AST corruption and beef up safety of `pure_getters`. | |||
| 2017-04-02 | fix corner cases in switch and undefined (#1762) | Alex Lam S.L | |
| - fix side effects in switch condition for singular blocks - fix `undefined` confusion with local variable - gate `OPT(AST_Switch)` with `switches` fixes #1758 fixes #1759 | |||
| 2017-03-27 | handle overlapped variable definitions (#1691) | Alex Lam S.L | |
| Process variable definitions with or without assigned values against: - `arguments` - named function arguments - multiple definitions within same scope Essentially demote variable declarations with no value assignments. Also fixed invalid use of `AST_VarDef` over `arguments` - should use a member of `AST_SymbolDeclaration` instead. | |||
| 2017-03-26 | fix `delete` related issues in `collapse_vars` and `reduce_vars` (#1689) | Alex Lam S.L | |
| 2017-03-25 | fix `reduce_vars` on `AST_Switch` (#1671) | Alex Lam S.L | |
| Take conditional nature of switch branches into account. fixes #1670 | |||
