2017-04-12convert `AST_Seq` from binary tree to array (#1460)...- rename `AST_Seq` to `AST_Sequence` - raise default sequences_limit from 200 to 800Alex Lam S.L
2017-04-09fix LHS cases for NaN & friends (#1804)...`Infinity = beyond` should not become `1/0 = beyond`Alex Lam S.L
2017-04-09enhance `test/ufuzz.js` (#1803)...- `-E` to report test cases with runtime errors - favor returning expressions rather than empty return - emit a newline upon fuzzer completion to not erase the iteration count closes #1800Alex Lam S.L
2017-04-08fix 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 typesAlex Lam S.L
2017-04-08fix `delete` corner cases (#1799)...- assignment - boolean - conditional - sequenceAlex Lam S.L
2017-04-07extend ufuzz generator (#1783)...- property access - property assignment - allow bare expression within try-block - normalise `Error` in `console.log()` - generate more unary expressions - add parenthesis to enforce precedence - adjust variable reuse/creation - add parameters to function declaration & expression - add return expression - add trivial arguments to function callAlex Lam S.L
2017-04-07fix `pure_getters` for chained property access (#1798)Alex Lam S.L
2017-04-07fix corner cases with `delete` (#1796)...`delete Infinity` returns `false` where as `delete (1/0)` returns `true`Alex Lam S.L
2017-04-07introduce "strict" to `pure_getters` (#1795)Alex Lam S.L
2017-04-07fix `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on catch variable (#1794)...Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`.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
2017-04-07fix 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
2017-04-06improve `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
2017-04-05implement 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 #1787Alex Lam S.L
2017-04-04optimise `do{...}while(false)` (#1785)...- better heuristics to avoid issues like #1532 - fix `TreeWalker.loopcontrol_target()` - `continue` cannot refer to `switch` blocksAlex Lam S.L
2017-04-04remove `--mangle-props` from fuzzing (#1777)...The inherently unsafe nature makes this feature unsuitable to be tested this way. fixes #1774Alex Lam S.L
2017-04-04exclude mangling of special property names (#1779)...- `null` - `true` - `false` - numeric literalsAlex Lam S.L

2017-04-03workaround Node.js bugs (#1775)...Wrap test code in IIFE before passing to `vm` fixes #1768 fixes #1771Alex Lam S.L
2017-04-03fix mangleProperties of `undefined` & `Infinity` (#1772)...`NaN` already works by the happy accident of `Number.NaN` fixes #1770Alex Lam S.L
