- 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` closes #96 closes #1366 fixes #124 fixes #263 fixes #379 fixes #423 fixes #576 fixes #737 fixes #958 fixes #1036 fixes #1175 fixes #1220 fixes #1223 fixes #1280
