Updates fonttools from 4.57.0 to 4.60.2

Release notes

Sourced from fonttools's releases.

4.60.2

  • Backport release Same as 4.61.0 but without "Drop support for EOL Python 3.9" change to allow downstream projects still on Python 3.9 to avail of the security fix for CVE-2025-66034 (#3994, #3999).

4.60.1

  • [ufoLib] Reverted accidental method name change in UFOReader.getKerningGroupConversionRenameMaps that broke compatibility with downstream projects like defcon (#3948, #3947, robotools/defcon#478).
  • [ufoLib] Added test coverage for getKerningGroupConversionRenameMaps method (#3950).
  • [subset] Don't try to subset BASE table; pass it through by default instead (#3949).
  • [subset] Remove empty BaseRecord entries in MarkBasePos lookups (#3897, #3892).
  • [subset] Add pruning for MarkLigPos and MarkMarkPos lookups (#3946).
  • [subset] Remove duplicate features when subsetting (#3945).
  • [Docs] Added documentation for the visitor module (#3944).

4.60.0

  • [pointPen] Allow reverseFlipped parameter of DecomposingPointPen to take a ReverseFlipped enum value to control whether/how to reverse contour direction of flipped components, in addition to the existing True/False. This allows to set ReverseFlipped.ON_CURVE_FIRST to ensure that the decomposed outline starts with an on-curve point before being reversed, for better consistency with other segment-oriented contour transformations. The change is backward compatible, and the default behavior hasn't changed (#3934).

  • [filterPen] Added ContourFilterPointPen, base pen for buffered contour operations, and OnCurveStartPointPen filter to ensure contours start with an on-curve point (#3934).

  • [cu2qu] Fixed difference in cython vs pure-python complex division by real number (#3930).

  • [varLib.avar] Refactored and added some new sub-modules and scripts (#3926).

    • varLib.avar.build module to build avar (and a missing fvar) binaries into a possibly empty TTFont,
    • varLib.avar.unbuild module to print a .designspace snippet that would generate the same avar binary,
    • varLib.avar.map module to take TTFont and do the mapping, in user/normalized space,
    • varLib.avar.plan module moved from varLib.avarPlanner.

    The bare fonttools varLib.avar script is deprecated, in favour of fonttools varLib.avar.build (or unbuild).

  • [interpolatable] Clarify linear_sum_assignment backend options and minimal dependency usage (#3927).

  • [post] Speed up build_psNameMapping (#3923).

  • [ufoLib] Added typing annotations to fontTools.ufoLib (#3875).

4.59.2

  • [varLib] Clear USE_MY_METRICS component flags when inconsistent across masters (#3912).
  • [varLib.instancer] Avoid negative advance width/height values when instatiating HVAR/VVAR, (unlikely in well-behaved fonts) (#3918).
  • [subset] Fix shaping behaviour when pruning empty mark sets (#3915, harfbuzz/harfbuzz#5499).
  • [cu2qu] Fixed dot() product of perpendicular vectors not always returning exactly 0.0 in all Python implementations (#3911)
  • [varLib.instancer] Implemented fully-instantiating avar2 fonts (#3909).
  • [feaLib] Allow float values in VariableScalar's axis locations (#3906, #3907).
  • [cu2qu] Handle special case in calc_intersect for degenerate cubic curves where 3 to 4 control points are equal (#3904).

4.59.1

  • [featureVars] Update OS/2.usMaxContext if possible after addFeatureVariationsRaw (#3894).
  • [vhmtx] raise TTLibError('not enough data...') when hmtx/vmtx are truncated (#3843, #3901).
  • [feaLib] Combine duplicate features that have the same set of lookups regardless of the order in which those lookups are added to the feature (#3895).
  • [varLib] Deprecate varLib.mutator in favor of varLib.instancer. The latter provides equivalent full (static font) instancing in addition to partial VF instancing.
    CLI users should replace fonttools varLib.mutator with fonttools varLib.instancer. API users should migrate to fontTools.varLib.instancer.instantiateVariableFont (#2680).

4.59.0

  • Removed hard-dependency on pyfilesystem2 (fs package) from fonttools[ufo] extra. This is replaced by the fontTools.misc.filesystem package, a stdlib-only, drop-in replacement for the subset of the pyfilesystem2's API used by fontTools.ufoLib. The latter should continue to work with the upstream fs (we even test with/without). However, clients who wish to continue using fs can do so by depending on it directly instead of via the fonttools[ufo] extra (#3885, #3620).
  • [xmlWriter] Replace illegal XML characters (e.g. control or non-characters) with "?" when dumping to ttx (#3868, #71).
  • [varLib.hvar] Fixed vertical metrics fields copy/pasta error (#3884).
  • Micro optimizations in ttLib and sstruct modules (#3878, #3879).
  • [unicodedata] Add Garay script to RTL_SCRIPTS (#3882).
