v3.9.0

• Bumped minimum depedencies:
  • fonttools >= 4.50.0
  • glyphsLib >= 6.7.0
  • ufo2ft >= 3.2.0
• The fontmake.instantiator was moved to ufo2ft.instantiator, with the same API. It's recommended that you import from the latter. The old module still works but will be removed at some point in the future.
• Fontmake can now build variable fonts with 'sparse' composite glyphs i.e. with either fewer or additional masters than their components' base glyphs, by interpolating missing sources on the fly. This works for both TTF and CFF2 variable fonts (googlefonts/glyphsLib#954).

v3.8.1

Bump minimum ufo2ft>=3.0.1, fixes a regression introduced in ufo2ft==3.0.0 when compiling a TrueType-flavored variable font with --drop-implied-oncurves option (#817).

v3.8.0

• Using the new ufo2ft 3.0.0, the feature writers now generate variable FEA that is compiled once per VF, instead of generating/compiling static features for each master and merge OTL tables with fontTools.varLib (provided that the masters do not have different features.fea). You can disable/force the old behavior by passing --no-variable-features fontmake CLI option (googlefonts/ufo2ft#635).
  This means fontmake now also supports hand-written variable FEA syntax when compiling variable fonts (see adobe-type-tools/afdko#1350).

• Updated minimum dependencies:

  • fonttools >= 4.48.1
    https://github.com/fonttools/fonttools/releases/tag/4.48.0
    https://github.com/fonttools/fonttools/releases/tag/4.48.1
  • glyphsLib >= 6.6.3
    https://github.com/googlefonts/glyphsLib/releases/tag/v6.6.2
    https://github.com/googlefonts/glyphsLib/releases/tag/v6.6.3
  • ufo2ft >= 3.0.0
    https://github.com/googlefonts/ufo2ft/releases/tag/v3.0.0

v3.7.2

• Improve compatibility checker (#1052).
• Bumped minimum dependencies:
  • fonttools >= 4.47.2
  • glyphsLib >= 6.6.1
• Pinned ufo2ft >=2.33.4, < 3 in view of upcoming major update that will change compilation of variable OpenType Layout tables, so one can revert to this stable fontmake version if any undesired effects arise.

v3.7.1

• Fixed ufo_structure incorrectly defaults to None (should be "package") in run_from_glyphs() method (#1024, #1025).

v3.7.0

• Added --glyph-data option to pass custom GlyphData XML files to glyphsLib (#1016, #245)
• Removed MutatorMath integration, as it no longer supported for reading/writing designspaces.
  If you want to continue using MutatorMath-only features such as extrapolation or anisotropic locations you can use ufoProcessor to create instance UFOs and then compile them with fontmake (#834, #1019).
• Don't save master/instance UFOs to disk by default unless explicitly requested via -o ufo. This means fontmake will no longer automatically leave behind itself temporary build byproducts such as "master_ufo" or "instance_ufo" in the current directory, but will only build what requested in -o option.
  Plus, when the only output is ufo, the --output-dir option can also be used to specify where to save the master/instance UFOs; and --output-path can be used when one specific instance UFO is built via -i {instance.name} (#1020).
• Added support for building from/exporting to ufoLib2's UFO JSON format, an experimental, unofficial method to serialize a UFO in a single json file. The old --save-ufo-as-zip option is deprecated and replaced with a new --ufo-structure that can be 'package' (the default .ufo directory), 'zip' (.ufoz) or 'json' (.ufo.json) (#1017).
  Also added an --indent-json option to dump JSON with 2-space indentation over multiple lines. By default, --ufo-structure=json dumps the whole font as single line, no indentation.
• Added 'repacker' to the extras, enables fonttools with HarfBuzz repacker support for better/faster serialization of GPOS and GSUB table, requires uharfbuzz (44f866e).
• Added --ttf-curves option to support building glyf v1 containing cubic Bezier curves, as being proposed in https://github.com/harfbuzz/boring-expansion-spec/blob/main/glyf1.md.
  The option controls whether cu2qu is run or not, and whether all cubics are converted to quadratic (default), or only when more economical to do so ('mixed') (#1021).
• Bumped minimum requirements:
  • fonttools >= 4.42.0
    https://github.com/fonttools/fonttools/releases/tag/4.41.0

v3.6.1

• Require glyphsLib>=6.2.5, for details see https://github.com/googlefonts/glyphsLib/releases.

v3.6.0

• [fontmake.instantiator] Allow the default DS source to load glyph data from a non-default UFO layer (#980).
• Dropped support for Python 3.7 which reached end of life, we now require Python 3.8 or greater.
• Added --no-auto-use-my-metrics option to disable setting USE_MY_METRICS component flags automatically in ufo2ft (#994).
• Added option to --drop-implied-oncurves to omit on-curve points that can be implied in TrueType contours, saves a few bytes on the glyf table size (#1005).
• Require:
  • fonttools >= 4.40.0
  • ufo2ft >= 2.32.0
  • glyphsLib >= 6.2.1
  • ufoLib2 >= 0.14.0

v3.5.1

• Implement support for 'Remove Glyphs' custom parameter (#958).
• [fontmake.instantiator] Use fontMath 'strict' mode to interpolate UFO glyphs to preserve geometry when off curve points coincide with on-curve points (#961, #962).

v3.5.0

• Added option to force disable compatibility checker to speed up build of variable fonts that are have been successfully built before (#916).
• Set the FEA include directory to the .glyphs file's directory; fixes issue building .glyphs file referencing external included feature files (googlefonts/glyphsLib#797, #917).
• Globally configure logging inside main(), following best practices, and deprecate FontProject class' verbose and timing parameters (#919).
• Support building from .glyphspackage bundles (i.e. alternative git-friendly format consisting of a directory containing one plist file per glyph) (#931).
• Bumped minimum required dependencies:
  • fonttools >= 3.38.0
  • ufo2ft >= 2.29.0
  • glyphsLib >= 6.1.0
