4.39.0 (released 2023-03-06) ---------------------------- - [mtiLib] Optionally add `Debg` debug info for MTI feature builds - [ttx] Support reading input file from standard input using special `-` character, similar to existing `-o -` option to write output to standard output - [cython] Prevent ``cython.compiled`` raise AttributeError if cython not installed properly - [OS/2] Guard against ZeroDivisionError when calculating xAvgCharWidth in the unlikely scenario no glyph has non-zero advance - [subset] Recompute xAvgCharWidth independently of --no-prune-unicode-ranges, previously the two options were involuntarily bundled together - [fontBuilder] Add ``debug`` parameter to addOpenTypeFeatures method to add source debugging information to the font in the ``Debg`` private table - [name] Make NameRecord `__lt__` comparison not fail on Unicode encoding errors - [featureVars] Fixed bug in ``overlayBox`` - [glyf] Added experimental support for cubic bezier curves in TrueType glyf table, as outlined in glyf v1 proposal https://github.com/harfbuzz/boring-expansion-spec/blob/main/glyf1-cubicOutlines.md - Added new qu2cu module and related qu2cuPen, the reverse of cu2qu for converting TrueType quadratic splines to cubic bezier curves - [glyf] Added experimental support for reading and writing Variable Composites/Components as defined in glyf v1 spec proposal https://github.com/harfbuzz/boring-expansion-spec/blob/main/glyf1-varComposites.md. - [pens]: Added `addVarComponent` method to pen protocols' base classes, which pens can implement to handle varcomponents (by default they get decompo - [misc.transform] Added DecomposedTransform class which implements an affine transformation with separate translate, rotation, scale, skew, and transformation-center components - [sbix] Ensure Glyph.referenceGlyphName is set; fixes error after dumping and re-compiling sbix table with 'dupe' glyphs - [feaLib] Be cleverer when merging chained single substitutions into same lookup when they are specified using the inline notation - [instancer] Clamp user-inputted axis ranges to those of fvar - [otBase/subset] Define ``__getstate__`` for BaseTable so that a copied/pickled 'lazy' object gets its own OTTableReader to read from; incidentally fixes a bug while subsetting COLRv1 table containing ClipBoxes on python 3.11 - [sbix] Handle glyphs with "dupe" graphic type on compile correctly - [glyf] ``endPointsOfContours`` field should be unsigned! Kudos to behdad for spotting one of the oldest bugs in FT. Probably nobody has ever dared to make glyphs with more than 32767 points... - [feaLib] Fixed handling of ``ignore`` statements with unmarked glyphs to match makeotf behavior, which assumes the first glyph is marked - Reformatted code with ``black`` and enforce new code style via CI check - [feaLib] Sort name table entries following OT spec prescribed order in the builder - [cu2quPen] Add Cu2QuMultiPen that converts multiple outlines at a time in interpolation compatible way; its methods take a list of tuples arguments that would normally be passed to individual segment pens, and at the end it dispatches the converted outlines to each pen - [reverseContourPen/ttGlyphPen] Add outputImpliedClosingLine option - [gvar] Avoid expanding all glyphs unnecessarily upon compile - [scaleUpem] Fixed bug whereby CFF2 vsindex was scaled; it should not - [designspaceLib] Add DS.getAxisByTag and refactor getAxis - [unicodedata] map Zmth<->math in ot_tag_{to,from}_script - [woff2] Support encoding/decoding OVERLAP_SIMPLE glyf flags - [instancer] Update OS/2 class and post.italicAngle when default moved (L4) - Dropped support for Python 3.7 which reached EOL, fontTools requires 3.8+. - [instancer] Fixed instantiateFeatureVariations logic when a rule range becomes default-applicable - [ttLib] Add main to ttFont and ttCollection that just decompile and re-compile the input font - [featureVars] Insert 'rvrn' lookup at the beginning of LookupList, to work around bug in Apple implementation of 'rvrn' feature which the spec says it should be processed early whereas on macOS 10.15 it follows lookup order - [instancer/mutator] Remove 'DSIG' table if present. - [svgPathPen] Don't close path in endPath(), assume open unless closePath()
