- Added `--optimize-cff` option to enable/disable CFF charstrings specialization and subroutinization.
The --{,no}subroutinize options are deprecated, but still work for a while (475).
- Bumped all minimum installation requirements, so that we can use the new ``fontTools.ufoLib`` module, which replaces the standalone ``ufoLib`` module, and adds support for UFOZ (zipped UFO) format, among other things:
+ fonttools[ufo,lxml,unicode] >= 3.32.0
+ cu2qu >= 1.6.5
+ glyphsLib >= 3.1.3
+ ufo2ft >= 2.5.0
+ MutatorMath >= 2.1.2
+ defcon[lxml] >= 0.6.0
+ booleanOperations >= 0.8.1
