- [varLib] Support generation of CFF2 variable fonts. ``model.reorderMasters()``
  now supports arbitrary mapping. Fix handling of overlapping ranges for feature
  variations (#1400).
- [cffLib, subset] Code clean-up and fixing related to CFF2 support.
- [ttLib.tables.ttProgram] Use raw strings for regex patterns (#1389).
- [fontbuilder] Initial support for building CFF2 fonts. Set CFF's
  ``FontMatrix`` automatically from unitsPerEm.
- [plistLib] Accept the more general ``collections.Mapping`` instead of the
  specific ``dict`` class to support custom data classes that should serialize
  to dictionaries.
