fixes #1368 | Alex Lam S.L |
| 2017-04-15 | drop `angular` (#1812)...Remove support for `@ngInject` as there are proper alternatives anyway. | 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 a couple of bugs in `global_defs` (#1802)...- `optimize()` substituted expression
- compute nested property string correctly
fixes #1801
Miscellaneous
- reset optimisation flags on all node types | Alex Lam S.L |
| 2017-04-08 | fix `delete` corner cases (#1799)...- assignment
- boolean
- conditional
- sequence | Alex Lam S.L |
| 2017-04-07 | fix `pure_getters` for chained property access (#1798) | 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 |
| 2017-04-07 | introduce "strict" to `pure_getters` (#1795) | Alex Lam S.L |
| 2017-04-07 | fix `reduce_vars` on catch variable (#1794)...Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`.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. | Alex Lam S.L |
| 2017-04-07 | fix incorrect context in variable substitution (#1791)...`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`. | Alex Lam S.L |
| 2017-04-06 | improve `pure_getters` (#1786)...- property access to `null` & `undefined` always has side effects
- utilise `reduce_vars` to determine safe property access
- may-be cases treated as side effects unless `unsafe` | Alex Lam S.L |
| 2017-04-05 | implement delayed resolution for `reduce_vars` (#1788)...Although it would be nice to enforce `AST_Node` cloning during transformation, that ship has sailed a long time ago.
We now get the assigned value when resolving `AST_SymbolRef` instead of `reset_opt_flags()`, which has the added advantage of improved compressor efficiency.
fixes #1787 | Alex Lam S.L |
| 2017-04-04 | optimise `do{...}while(false)` (#1785)...- better heuristics to avoid issues like #1532
- fix `TreeWalker.loopcontrol_target()`

- gate `OPT(AST_Switch)` with `switches`
fixes #1758
fixes #1759 | Alex Lam S.L |
| 2017-04-01 | fix switch branch elimination (#1752)...Merge unreachable case body with previous fallthrough case
fixes #1750 | 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

| 2017-03-31 | combine rules for binary boolean operations (#1744) | Alex Lam S.L |
| 2017-03-31 | sort options in alphabetical order (#1743)...They started off as functional groups I guess, but given the sheer number of options this is becoming too difficult to read. | Alex Lam S.L |

| 2017-03-30 | optimize try-catch-finally (#1731)...- eliminate empty blocks
- flatten out if try-block does not throw | Alex Lam S.L |
| 2017-03-29 | speed up IIFE elimination (#1728)...- `side_effects` will clean up inner statements, so checking for an empty function body should suffice
- drop side effects when dropping `return` from statement | Alex Lam S.L |
| 2017-03-29 | speed up `equivalent_to()` and `AST_Switch` (#1727) | Alex Lam S.L |
