- Update to 4.47.0
- [varLib.models] New API for VariationModel: getMasterScalars and interpolateFromValuesAndScalars.
- [varLib.interpolatable] Various bugfixes and rendering improvements.
In particular, add a Summary page in the front, and an Index and Table-of-Contents in the back.
Change the page size to Letter.
- [Docs/designspaceLib] Defined a new public.fontInfo lib key, not used anywhere yet (#3358).
- Changes from 4.46.0
- [featureVars] Allow to register the same set of substitution rules to multiple features.
The addFeatureVariations function can now take a list of featureTags; similarly, the lib key 'com.github.fonttools.varLib.featureVarsFeatureTag' can now take a comma-separateed string
of feature tags (e.g. "salt,ss01") instead of a single tag (#3360).
- [featureVars] Don't overwrite GSUB FeatureVariations, but append new records to it
for features which are not already there. But raise VarLibError if the feature tag
already has feature variations associated with it (#3363).
- [varLib] Added addGSUBFeatureVariations function to add GSUB Feature Variations to
an existing variable font from rules defined in a DesignSpace document (#3362).
- [varLib.interpolatable] Various bugfixes and rendering improvements. In particular,
a new test for "underweight" glyphs. The new test reports quite a few false-positives though.
Please send feedback.
- Changes from 4.45.1
- [varLib.interpolatable] Various bugfixes and improvements, better reporting, reduced false positives.
- [ttGlyphSet] Added option to not recalculate glyf bounds (#3348).
- Changes from 4.45.0
- [varLib.interpolator] Vastly improved algorithms. Also available now is --pdf and
--html options to generate a PDF or HTML report of the interpolation issues.

as well as the proposed fixed version.

before some changes were introduced in fonttools 4.44.0 (#3333).

- [feaLib] Ensure variable mark anchors are deep-copied while building
since they get modified in-place and later reused (#3330).

- Changes from 4.44.0
- [instancer] Recalc OS/2 AvgCharWidth after instancing if default changes (#3317).

https://codeql.github.com/codeql-query-help/python/py-xxe/
- [varLib.iup] Added workaround for a Cython bug in iup_delta_optimize
that was leading to IUP tolerance being incorrectly initialised,
resulting in sub-optimal deltas (6012643, cython/cython#5732).
- [varLib] Added new command-line entry point fonttools varLib.avar to add an avar table
to an existing VF from axes mappings in a .designspace file (0a3360e).

was not passed on to findMultilingualName (#3253).
- Changes from 4.42.0
- [varLib] Use sentinel value 0xFFFF to mark a glyph advance in hmtx/vmtx as non participating,
allowing sparse masters to contain glyphs for variation purposes other than {H,V}VAR (#3235).
- [varLib/cff] Treat empty glyphs in non-default masters as missing,
thus not participating in CFF2 delta computation, similarly to how
varLib already treats them for gvar (#3234).
- Added varLib.avarPlanner script to deduce 'correct' avar v1 axis mappings based on glyph average weights (#3223).

for converting VOLT OpenType Layout sources to FEA format (#3164).

- Published native binary wheels to PyPI for all the python minor versions
and platform and architectures currently supported that would benefit from this.
They will include precompiled Cython-accelerated modules (e.g. cu2qu) without
requiring to compile them from source. The pure-python wheel and source distribution
will continue to be published as always (pip will automatically chose them when no
binary wheel is available for the given platform, e.g. pypy).
Use pip install --no-binary=fonttools fonttools to expliclity request pip to install from the pure-python source.

- Added CI workflow config file for building native binary wheels (#3121).
- [fontBuilder] Added glyphDataFormat=0 option; raise error when glyphs contain cubic outlines
but glyphDataFormat was not explicitly set to 1 (#3113, #3119).
- [subset] Prune emptied GDEF.MarkGlyphSetsDef and remap indices; ensure GDEF is subsetted before GSUB and GPOS (#3114, #3118).
