v3.7.0

• Dropped support for Python 3.9 (EOL).
• Fixed regression introduced with v3.6.0 whereby ufoLib2 was imported
  unconditionally in ufo2ft.instantiator while not being declared as
  a required dependency in pyproject.toml. We now restored compatibility
  with defcon, and neither defcon nor ufoLib2 is strictly required given
  that ufo2ft API is designed to be agnostic and work with either (#956).

v3.6.9

• [kernFeatureWriter] Fixed adding unreferenced lookups to GPOS LookupList when a feature block was skipped because already present in features.fea (#962, #960)

v3.6.8

• Fixed regression introduced in ufo2ft v3.6.7 as we replaced setup.py with pyproject.toml: dependencies were unnecessarily pinned to exact versions causing version clashes when ufo2ft was installed in the same environment as other libraries (#954).

v3.6.7

• Replace setup.py with pyproject.toml (#950).
• [instantiator] Copy all fontinfo attributes for single-master static instance fonts (#953, googlefonts/gftools#1144).
• [outlineCompiler] clamp xAvgCharWidth to avoid overflows when compiling 'sparse' master TTFs
• Use Trusted Publishing to upload packages to PyPI (#947).

v3.6.6

• [instantiator] Fixed bug in InterpolatedLayer.__getitem__ whereby a new glyph instance was interpolated when the original source layer's glyph object contained zero contours and as such evaluated to False. This bug affected in particular the PropagateAnchorsIFilter filter, where anchors would sometimes not be propagated correctly (#948, googlefonts/fontc#1646).

v3.6.5

• [preProcessor] Ensure components whose 2x2 transform overflows F2Dot14 bounds get decomposed before the other filters, instead of relying on fonttools TTGlyphPen to decompose them for us (#946).

v3.6.4

• decomposeCompositeGlyph: use ReverseFlipped.ON_CURVE_FIRST to ensure that, when decomposing flipped components (with negative determinant), before reversing the contour winding direction, the first point is always an on-curve point (googlefonts/fontc#1633).
• Require fonttools >= 4.60.0
  https://github.com/fonttools/fonttools/releases/tag/4.60.0

v3.6.3

• [instantiator] Copy openTypeOS2Panose values from default source to interpolated instance UFOs when shared by all the sources, and set to 0 the values that differ (#953, #943).

v3.6.2

• [instantiator] Fixed bug introduced in v3.6.0 whereby the generated instance UFOs were getting duplicate entries in fontinfo openTypeNameRecords for English strings mistaken for localized names, resulting in unnecessary name records (#941, #942).

v3.6.1

• Set autoUseMyMetrics=False by default for variable fonts. It's only useful for fonts with hinted horizontal glyph metrics (#940).
