• Fixed uploading wheels to PyPI, no code changes since v4.48.0.

• [varLib] Do not log when there are no OTL tables to be merged.
• [setup.py] Do not restrict lxml<5 any more, tests pass just fine with lxml>=5.
• [feaLib] Remove glyph and class names length restrictions in FEA (#3424).
• [roundingPens] Added transformRoundFunc parameter to the rounding pens to allow for custom rounding of the components' transforms (#3426).
• [feaLib] Keep declaration order of ligature components within a ligature set, instead of sorting by glyph name (#3429).
• [feaLib] Fixed ordering of alternates in aalt lookups, following the declaration order of feature references within the aalt feature block (#3430).
• [varLib.instancer] Fixed a bug in the instancer's IUP optimization (#3432).
• [sbix] Support sbix glyphs with new graphicType "flip" (#3433).
• [svgPathPen] Added --glyphs option to dump the SVG paths for the named glyphs in the font (0572f78).
• [designspaceLib] Added "description" attribute to <mappings> and <mapping> elements, and allow multiple <mappings> elements to group <mapping> elements that are logically related (#3435, #3437).
• [otlLib] Correctly choose the most compact GSUB contextual lookup format (#3439).

Minor release to fix uploading wheels to PyPI.

• [merge] Improve help message and add standard command line options (#3408)
• [otlLib] Pass ttFont to name.addName in buildStatTable (#3406)
• [featureVars] Re-use FeatureVariationRecords when possible (#3413)

• [varLib.models] New API for VariationModel: getMasterScalars and interpolateFromValuesAndScalars.
• [varLib.interpolatable] Various bugfixes and rendering improvements. In particular, add a Summary page in the front, and an Index and Table-of-Contents in the back. Change the page size to Letter.
• [Docs/designspaceLib] Defined a new public.fontInfo lib key, not used anywhere yet (#3358).

• [featureVars] Allow to register the same set of substitution rules to multiple features. The addFeatureVariations function can now take a list of featureTags; similarly, the lib key 'com.github.fonttools.varLib.featureVarsFeatureTag' can now take a comma-separateed string of feature tags (e.g. "salt,ss01") instead of a single tag (#3360).
• [featureVars] Don't overwrite GSUB FeatureVariations, but append new records to it for features which are not already there. But raise VarLibError if the feature tag already has feature variations associated with it (#3363).
• [varLib] Added addGSUBFeatureVariations function to add GSUB Feature Variations to an existing variable font from rules defined in a DesignSpace document (#3362).
• [varLib.interpolatable] Various bugfixes and rendering improvements. In particular, a new test for "underweight" glyphs. The new test reports quite a few false-positives though. Please send feedback.

• [varLib.interpolatable] Various bugfixes and improvements, better reporting, reduced false positives.
• [ttGlyphSet] Added option to not recalculate glyf bounds (#3348).

• [varLib.interpolator] Vastly improved algorithms. Also available now is --pdf and --html options to generate a PDF or HTML report of the interpolation issues.
  The PDF/HTML report showcases the problematic masters, the interpolated broken glyph, as well as the proposed fixed version.

• [subset] Only prune codepage ranges for OS/2.version >= 1, ignore otherwise (#3334).
• [instancer] Ensure hhea vertical metrics stay in sync with OS/2 ones after instancing MVAR table containing 'hasc', 'hdsc' or 'hlgp' tags (#3297).

• [glyf] Have Glyph.recalcBounds skip empty components (base glyph with no contours) when computing the bounding box of composite glyphs. This simply restores the existing behavior before some changes were introduced in fonttools 4.44.0 (#3333).
