Changelog
### 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).
```
### 4.41.1
```
----------------------------
- [subset] Fixed perf regression in v4.41.0 by making ``NameRecordVisitor`` only visit
tables that do contain nameID references (3213, 3214).
- [varLib.instancer] Support instancing fonts containing null ConditionSet offsets in
FeatureVariationRecords (3211, 3212).

timestamp, regression introduced in v4.40.0 (3210).

```
### 4.40.0
```
----------------------------
- 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.
- [designspaceLib|varLib] Add initial support for specifying axis mappings and build
``avar2`` table from those (3123).
- [feaLib] Support variable ligature caret position (3130).
- [varLib|glyf] Added option to --drop-implied-oncurves; test for impliable oncurve
points either before or after rounding (3146, 3147, 3155, 3156).
- [TTGlyphPointPen] Don't error with empty contours, simply ignore them (3145).
- [sfnt] Fixed str vs bytes remnant of py3 transition in code dealing with de/compiling
WOFF metadata (3129).

- [pens] Added filter pen that explicitly emits closing line when lastPt != movePt (3100).
- [varStore] Improve optimize algorithm and better document the algorithm (3124, 3127).
Added ``quantization`` option (3126).
- 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).
- [xmlReader] Fixed issue whereby DSIG table data was incorrectly parsed (3115, 2614).
- [varLib/merger] Fixed merging of SinglePos with pos=0 (3111, 3112).

and referenced feature is empty (3110).
- [feaLib] Dedupe multiple substitutions with classes (3105).
```
### 4.39.4

SpooledTemporaryFile, seekable method only added on python 3.11 (3052).
```
### 4.39.2
```
----------------------------
- [varLib] Fixed regression introduced in 4.39.1 whereby an incomplete 'STAT' table
would be built even though a DesignSpace v5 did contain 'STAT' definitions (3045, 3046).
```
### 4.39.1
```
----------------------------
- [avar2] Added experimental support for reading/writing avar version 2 as specified in
this draft proposal: https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md

because of a macOS bug (3034).

- [varLib] When building VF, do not overwrite a pre-existing ``STAT`` table that was built

defined in Designspace v5 from ``fonttools varLib`` script (3024).
- [mtiLib] Only add ``Debg`` table with lookup names when ``FONTTOOLS_LOOKUP_DEBUGGING``
env variable is set (3023).
```
### 4.39.0
```
----------------------------
- [mtiLib] Optionally add `Debg` debug info for MTI feature builds (3018).
- [ttx] Support reading input file from standard input using special `-` character,
similar to existing `-o -` option to write output to standard output (3020).
- [cython] Prevent ``cython.compiled`` raise AttributeError if cython not installed
properly (3017).
- [OS/2] Guard against ZeroDivisionError when calculating xAvgCharWidth in the unlikely
scenario no glyph has non-zero advance (3015).
- [subset] Recompute xAvgCharWidth independently of --no-prune-unicode-ranges,
previously the two options were involuntarily bundled together (3012).
- [fontBuilder] Add ``debug`` parameter to addOpenTypeFeatures method to add source
debugging information to the font in the ``Debg`` private table (3008).

- Added new qu2cu module and related qu2cuPen, the reverse of cu2qu for converting
TrueType quadratic splines to cubic bezier curves (2993).
- [glyf] Added experimental support for reading and writing Variable Composites/Components
as defined in glyf v1 spec proposal (2958):
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 decomposed) (2958).
- [misc.transform] Added DecomposedTransform class which implements an affine transformation
with separate translate, rotation, scale, skew, and transformation-center components (2598)
- [sbix] Ensure Glyph.referenceGlyphName is set; fixes error after dumping and
re-compiling sbix table with 'dupe' glyphs (2984).
- [feaLib] Be cleverer when merging chained single substitutions into same lookup
when they are specified using the inline notation (2150, 2974).
- [instancer] Clamp user-inputted axis ranges to those of fvar (2959).
- [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 (2965, 2968).
- [sbix] Handle glyphs with "dupe" graphic type on compile correctly (2963).
- [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... (2957).
- [feaLib] Fixed handling of ``ignore`` statements with unmarked glyphs to match
makeotf behavior, which assumes the first glyph is marked (2950).
- Reformatted code with ``black`` and enforce new code style via CI check (2925).
- [feaLib] Sort name table entries following OT spec prescribed order in the builder (2927).
- [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 (2912).
- [reverseContourPen/ttGlyphPen] Add outputImpliedClosingLine option (2913, 2914,
2921, 2922, 2995).
- [gvar] Avoid expanding all glyphs unnecessarily upon compile (2918).

- [woff2] Support encoding/decoding OVERLAP_SIMPLE glyf flags (2576, 2884).
- [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 (2737, 2880).
- [ttLib] Add main to ttFont and ttCollection that just decompile and re-compile the
input font (2869).
- [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 (2140, 2867).
- [instancer/mutator] Remove 'DSIG' table if present.
- [svgPathPen] Don't close path in endPath(), assume open unless closePath() (2089, 2865).
