- refactor `screw_ie8` to `ie8`
- compact `sourceMap` options
- more stringent verification on input `options`
- toplevel shorthands
- `ie8`
- `keep_fnames`
- `toplevel`
- deprecated `fromString` in `minify()`
- `minify()` no longer handles any `fs` operations
- unify order of operations for `mangle_properties()` on CLI & API
- `bin/uglifyjs` used to `mangle_properties()` before even `Compressor`
- `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()`
- both will now do `Compressor`, `mangle_names()` then `mangle_properties()`
- `options.parse` / `--parse` for parser options beyond `bare_returns`

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
