v1.8.0

• 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
