v3.3.0

• Rewrite old kern writer to pull in some changes made in the newer one (#870)
• markFeatureWriter: Support contextual anchors (#869)
• markFeatureWriter: Support contextual ligature anchors (#871)

v3.2.8

• [featureWriters] Ensure CursFeatureWriter comes first, before kerning mark feature writers; in some non-HarfBuzz implementations the GPOS lookup order matters (#864).
• [kernFeatureWriter] Ignore zero-valued class-class kerning pairs when generating variable kern feature as they are no-op (#866).
• Take discrete axes into account when checking for feature compatibility across masters (#867).

v3.2.7

• cursFeatureWriter: Remove stray print()

v3.2.6

• kernFeatureWriter: Support sparse masters (#859)
• cursFeatureWriter: Support multiple entry/exit anchor pairs (#863)

v3.2.5

• Removed unnecessary assertions that may sometime trigger an AssertionError while setting a glyph's right margin in dottedCircle filter (#849).

v3.2.4

• Fix variable anchors when DesignSpace source specifies a layer (#842).
• Update the old kernFeatureWriter2.py to be able to output variable FEA for use when compiling features once per VF (#841, #845).

v3.2.3

[markFeatureWriter] When building variable anchors from designspace sources, don't crash if a non-default, 'sparse' UFO source does not contain some glyph; simply skip it (#840).

v3.2.2

• Make it easier to use variable features by allowing to put them in the default source only (#833).
• [instructionCompiler] When compiling TrueType glyph instructions, round TTGlyph's component transforms with floatToFixedToFloat(precisionBits=14) before computing their hash; the hash stored in the UFO glyph lib, which the computed hash is compared against, was itself computed from compiled (i.e. rounded) values (#814).

v3.2.1

• [BaseIFilter] Fixed performance regression when decomposing composite glyphs in fonts with large number of masters and/or nested components.
  We now use a cache to avoid recursing too much when gathering locations from component glyphs (#829).

v3.2.0

• Some bug fixes and better error handling while building MATH table (#820).
• Fixed a error while building variable GDEF ligature carets (#821).
• Added new ufo2ft.instantiator module, copied over from fontmake.instantiator and adapted to also work on defcon Font objects, in addition to ufoLib2.Font (#825).
• Support compiling variable TTF or CFF2 fonts with 'sparse' composite glyphs which define either more or fewer sources than the glyphs used as components. We use the instantiator to interpolate glyphs on the fly while decomposing, or we add empty placeholders in TTF masters for missing components in the non-default masters so the sparse composites can be built with varLib (googlefonts/glyphsLib#954, #826).
