Sourced from fonttools's releases.

4.61.0

• [varLib.main]: SECURITY Only use basename(vf.filename) to prevent path traversal attacks when running fonttools varLib command-line script, or code which invokes fonttools.varLib.main(). Fixes CVE-2025-66034, see: GHSA-768j-98cg-p3fv.
• [feaLib] Sort BaseLangSysRecords by tag (#3986).
• Drop support for EOL Python 3.9 (#3982).
• [instancer] Support --remove-overlaps for fonts with CFF2 table (#3975).
• [CFF2ToCFF] Add --remove-overlaps option (#3976).
• [feaLib] Raise an error for rsub with NULL target (#3979).
• [bezierTools] Fix logic bug in curveCurveIntersections (#3963).
• [feaLib] Error when condition sets have the same name (#3958).
• [cu2qu.ufo] skip processing empty glyphs to support sparse kerning masters (#3956).
• [unicodedata] Update to Unicode 17. Require unicodedata2 >= 17.0.0 when installed with 'unicode' extra.

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).
