v2.31.0

• Dropped support for Python 3.7 which reached EOL. We now require Python >= 3.8.
• Take into account extra substitutions found in DesignSpace rules when classifying glyphs by various unicode properties in feature writers (#731).
• Added support for compiling TrueType instructions and flags stored in the UFO's public.truetype.* lib keys (#654).
• Automatically compute COLRv1 ClipBoxes if none are explicitly provided. This is enabled by default for static builds only. You can set colrAutoClipBoxes=True for interpolatable/variable builds if safe to do so (#728).
• Improved "no default source" error (#677).
• Warn about mis-cased # Automatic Code insertion marker comments; also warn if there are no insertion markers but kerning.plist is non empty and there are manual kern/dist features in the FEA code (#719).
• Respect openTypeNameRecords overrides for the predefined name IDs (#727).
• Reorder class definitions in feature writers such that they appear before the lookups that use them (#725).
• Renamed dottedCircleFilter module to dottedCirlce, was wrongly named; old kept for backward compat (#716).
• [kernFeatureWriter] Avoid overwriting classDefs (#705).
  Register kern lookups for all defined languages (#711).
  Correctly split mark and base kerning pairs (#713).
  Don't skip over spacing marks when kerning (#720).
• Fixed FEA include dir detection when in current dir (#689)
• Automatically decompose components when 2x2 transforms differ (#698)
• [kernFeatureWriter] Split kerning by script, not horizontal direction, which should be faster to compile and produce smaller GPOS. The old kernFeatureWriter is still kept in a separate module (#679, #636, #697).
