| 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 |
| 2017-04-08 | fix `delete` corner cases (#1799)...- assignment
- boolean
- conditional
- sequence | Alex Lam S.L |
| 2017-04-02 | fix corner cases in switch and undefined (#1762)...- 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 | Alex Lam S.L |
| 2017-03-27 | fix `cascade` on anonymous function reference (#1693)...Unlike normal variables and even function definitions, these cannot be reassigned, even though assignment expressions would "leak" the assigned value as normal. | Alex Lam S.L |
| 2017-03-26 | fix `cascade` on `delete` operator (#1687)...Conditions including strict mode would make `delete` return `true` or `false`, and are too complex to be evaluated by the compressor.
Suppress assignment folding into said operator.
fixes #1685 | 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 | fix AST_Binary.lift_sequences() (#1621)...Commit eab99a1c fails to account for side effects from compound assignments. | 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 |
| 2017-03-03 | 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 |
| 2017-02-21 | 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

| 2017-02-21 | `-c sequences=N` suboptimal at N expression cutoff...N = 2:
a;
b;
c;
d;
was:
a, b;
c;
d;
now:
a, b;
c, d;

| 2014-09-28 | Referencing a global is assumed to have side effects....Close #550
| Mihai Bazon |
| 2013-11-06 | Better fix for #343...We can in fact lift sequences, but only if the operation is assignment and
the left-hand side has no side effects nor property access -- that should
guarantee that whatever we place before it cannot affect the sense of the
assignment.
Dropped contrived test case (too hard to support it now), added a more
meaningful one.

| 2012-10-30 | don't move expressions containing the binary `in` operator into the `for` ini......(opera can't parse it)
close #25

| 2012-10-22 | more sequence optimizations (lift some sequences above binary/unary expressio... | Mihai Bazon |
| 2012-09-24 | minor tests fix | Mihai Bazon |
| 2012-09-17 | one more test for sequences | Mihai Bazon |
| 2012-08-22 | wrote more of the compressor and added some tests | Mihai Bazon |
