v2.29.0b1

• [KernFeatureWriter] Split kerning by script, not by direction (#636). (REVERTED)
• [FeatureCompiler] Added feaIncludeDir option to override the default include search path (#637).

v2.28.0

• Added dotted circle filter (#593).
• Decompose transformed components across interpolatable masters, when the option filter is used on building VFs (#609).
• Add support for building from DesignSpace Version 5 (#598).
• Fixed regression introduced in v2.25.0 (Oct 2021) about a compile parameter named cubicConversionError (#622).
• [filters] Sort glyphs by decreasing component depth to avoid order-dependent issues (#621, #625).
• Automatically disable COLR layer reuse for interpolatable masters when building variable COLR fonts.
  Added colrLayerReuse=True compile option to force it off in the final COLR font as well (#627).

v2.28.0a1

• Add dotted circle filter by @simoncozens in #593. The filter will generate the dottedCircle (U+25CC) glyph for you and fill in all base anchor according to what anchors it finds in the font.
• Decompose transformed components across masters by @simoncozens in #609 instead of only for the masters that trigger the filter, to remain compatible.
• Implement Designspace v5 compilation by @belluzj in #598

Full Changelog: v2.27.0...v2.28.0a1

v2.27.0

• Support extending the lists of custom filters and featureWriters already defined in the UFO lib.plist.
  Both parameters can now contain a special sentinel value (... or Ellipsis) that act as placeholder so one can insert additional filters/featureWriters before or after these (#604).

v2.26.0

• Disable GPOS optimization while building the intermediate variable font masters (#599)
• Add static method PostProcessor.rename_glyphs (#600)

v2.25.3

• Fix dist-enabled scripts (#582)
• Move unknown anchors to abvm (#580)
• Consider scripts with no directionality to be LTR (#576)
• Fix typo in USE_SCRIPTS list (#570)

v2.25.2

• [markFeatureWriter] Use abvm/blwm features for USE scripts and Khmer (#567).
• [kernFeatureWriter] Don't crash when there are only base-mark kerns (#569).

v2.25.1

Fixed regression in compileVariableTTF rejecting valid keyword arguments (#551, googlefonts/fontmake#817)

v2.25.0

• Drop Python 3.6 support, require Python >= 3.7 (#541)
• [COLR] Don't copy color layer refers to a glyph in the same UFO layer,
  don’t make an pessary copy of the glyph (#538)
• [preProcessoer] Apply ExplodeColorLayerGlyphsFilter to interpolatable
  TTFs (#537)
• [featureWriters] Add writer for curs feature (#476)
• [doc] Document color layers lib keys (#536)

v2.24.0

• [filters] Also transform advance width and height when applying a scale through
  the Transformations filter (#490, #515).
• [COLR] Define new 'colrClipBoxes' lib key, to be used with colorLib.buildCOLR
  for building COLRv1 ClipList table (#521).
