4.47.2

Minor release to fix uploading wheels to PyPI.

4.47.1

• [merge] Improve help message and add standard command line options (#3408)
• [otlLib] Pass ttFont to name.addName in buildStatTable (#3406)
• [featureVars] Re-use FeatureVariationRecords when possible (#3413)

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).

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.

4.45.1

• [varLib.interpolatable] Various bugfixes and improvements, better reporting, reduced false positives.
• [ttGlyphSet] Added option to not recalculate glyf bounds (#3348).
