- update to 4.18.2:
- [COLRv1] Implemented ``PaintTranslate`` paint format (#2129).
- [varLib.cff] Fixed unbound local variable error (#1787).
- [otlLib] Don't crash when creating OpenType class definitions if some glyphs
occur more than once (#2125).
- [colorLib] Speed optimization for ``LayerV1ListBuilder`` (#2119).
- [mutator] Fixed missing tab in ``interpolate_cff2_metrics`` (0957dc7a).
- [COLRv1] Update to latest draft: added ``PaintRotate`` and ``PaintSkew`` (#2118).
- [woff2] Support new ``brotlicffi`` bindings for PyPy (#2117).
- [glifLib] Added ``expectContentsFile`` parameter to ``GlyphSet``, for use when
reading existing UFOs, to comply with the specification stating that a
``contents.plist`` file must exist in a glyph set (#2114).
- [subset] Allow ``LangSys`` tags in ``--layout-scripts`` option (#2112). For example:
``--layout-scripts=arab.dflt,arab.URD,latn``; this will keep ``DefaultLangSys``
and ``URD`` language for ``arab`` script, and all languages for ``latn`` script.
- [varLib.interpolatable] Allow UFOs to be checked; report open paths, non existant
glyphs; add a ``--json`` option to produce a machine-readable list of
incompatibilities
- [pens] Added ``QuartzPen`` to create ``CGPath`` from glyph outlines on macOS.
Requires pyobjc (#2107).
- [feaLib] You can export ``FONTTOOLS_LOOKUP_DEBUGGING=1`` to enable feature file
debugging info stored in ``Debg`` table (#2106).
- [otlLib] Build more efficient format 1 and format 2 contextual lookups whenever
possible (#2101).
- [colorLib] Fixed regression in 4.17.0 when building COLR v0 table; when color
layers are stored in UFO lib plist, we can't distinguish tuples from lists so
we need to accept either types (e5439eb9, googlefonts/ufo2ft/issues#426).
- [colorLib/otData] Updated to latest draft ``COLR`` v1 spec (#2092).
- [svgLib] Fixed parsing error when arc commands' boolean flags are not separated
by space or comma (#2094).
