| 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 |

| 2016-07-01 | Change the default sequences limit to 200 to speed up compress....Has little or no impact on minification size in the majority of
cases but can speed up rollup builds significantly.
This sequences change also has the beneficial side effect of avoiding
"stack size exceeded" errors on very large input files.
The user is free to alter the sequences limit if they are so inclined.
The previous sequences limit was 2000. 20 is often sufficient.
| kzc |
| 2016-07-01 | Allow sequences maximum length to be user configurable. | kzc |
| 2016-06-30 | Enable --screw-ie8 by default....catch identifier is mangled correctly for ES5 standards-compliant JS engines by default.
Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled.
To support non-standard ie8 javascript use: uglifyjs --support-ie8

| 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.

| 2015-11-16 | Limit max iterations for tighten_body...Ref #866
| Mihai Bazon |
| 2015-11-11 | Rework has_directive...It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope. It's thus no longer necessary
to call `figure_out_scope` before codegen. Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.
Fix #861
