| 2017-04-17 | fix `reduce_vars` on boolean binary expressions (#1819)...Side effects of `&&` and `||` have not mattered until #1814, which takes assignment expressions into account. | Alex Lam S.L |
| 2017-04-17 | compress duplicated variable definitions (#1817)...These are surprisingly common, as people reuse the same variable name within loops or switch branches. | Alex Lam S.L |
| 2017-04-17 | fix `reduce_vars` within try-block (#1818)...Possible partial execution due to exceptions. | Alex Lam S.L |

- relax modification rule for immutable value
- fix order of visit for TreeWalker
- remove extraneous code | Alex Lam S.L |

- improve overhead accounting | Alex Lam S.L |
| 2017-04-16 | update README (#1813)...- mention major version bump
- remove reference to internal API | Alex Lam S.L |
| 2017-04-15 | unify CLI & API under `minify()` (#1811)...- rename `screw_ie8` to `ie8`

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 |

- favor returning expressions rather than empty return
- emit a newline upon fuzzer completion to not erase the iteration count
closes #1800 | Alex Lam S.L |
| 2017-04-08 | fix a couple of bugs in `global_defs` (#1802)...- `optimize()` substituted expression

fixes #1801
Miscellaneous

| 2017-04-08 | fix `delete` corner cases (#1799)...- assignment
- boolean

| 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on catch variable (#1794)...Improved catch handling in `figure_out_scope()` means special case treatment of IE8 is no longer valid in `reset_opt_flags()`.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 |
| 2017-04-07 | enable `inline_script` by default (#1793) | 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()`
- `continue` cannot refer to `switch` blocks | Alex Lam S.L |
| 2017-04-04 | remove `--mangle-props` from fuzzing (#1777)...The inherently unsafe nature makes this feature unsuitable to be tested this way.
fixes #1774 | Alex Lam S.L |
| 2017-04-04 | exclude mangling of special property names (#1779)...- `null`
- `true`
- `false`

- attempt to show beautified output only when `run_code()` output is preserved | 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
fixes #1730 | Alex Lam S.L |
| 2017-03-31 | combine rules for binary boolean operations (#1744) | Alex Lam S.L |
| 2017-03-31 | Massive extension of the fuzzer (#1697)...Fix bug where a `throw` was generated without expression
Reenable try/catch/finally and fix them up
Skip serialization errors
Allow function decl in other funcs but not in blocks etc
Rename function to be more appropriate
Fix global functions not getting certain names
Make the canaries more likely to appear as expressions
Add a silly rounding edge case
Add a new canary, `c`, which should only ever be incremented
Refactoring
Fix (another) iife not actually being invoked
When a statement hits recursion max return an expression instead of `;`
When a expression hits recursion max also inc `c`
Generate global code as well as function code
Also fixes some argument juggling related bugs.
No longer reduces the recursion max when generating sub functions.
Generates a function arg.
Add used names to var name pool while in that scope
This is a little wonky, possibly a hack, but since it's synchronous code I think it's alright to do this. The alternative is to slice the varnames array and juggle them through almost all the generator functions and there are various reasons why this patch is a better alternative.
Minify generated code, not beautified code. Prevents beautifier bias.
Prevent unnecessary duplication
Remove serialization protection because I think it got handled elsewhere
Abstract toplevel code generation
Add example line of running test case
Add poor man options parser, and some options
Reindent to 4 spaces
Lower chance of `default` generation
Comment example of testing a case and output improvement
Enable `default` clause appearing at any clause index
Removing some training wheels; dont add parens where we dont absolutely need them
Support `-s1` and `-s2` to force specific statements being generated at that recursion level
Add round number to output when failing. For stats and fun and profit.
Solidify statement depth counting. The argument juggling is real.
Renamed option to something long. -scf was ugly and probably confusing.
Fix missing arguments causing `canThrow` to be truthy, generating crashing code
Generate more binary nested expressions
Add black and white list cli options for statement generation
Allows you to explicitly require or forbid certain statements from/to being made.
```
node test/ufuzz.js --without-stmt switch,try -t 5 -r 5 -V
```
```
node test/ufuzz.js --only-stmt ifelse,expr -t 5 -r 5 -V
```
Similar granularity for expression may be added later.
There can be no comma between names; it just does a split on that arg.
Trim down the binary expression generator
Prevent scoping issues in nodejs by preventing certain names in global space
Oh this list was incomplete?
Allow bin-expr to generate assignments too. More vigilant with storing and reusing vars.
Add more global builtin names
Update wrapper code
Also patch Function valueOf | Peter van der Zee |
| 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 |
| 2017-03-31 | v2.8.20 | Alex Lam S.L |
| 2017-03-31 | fix missing preamble when shebang is absent (#1742) | Alex Lam S.L |
| 2017-03-31 | v2.8.19 | Alex Lam S.L |
| 2017-03-31 | fix catch symbol mangling (#1734)...Only need to look up the immediate non-block/catch scope for the same-name special case.
fixes #1733 | Alex Lam S.L |
