v6.9.3

• [builder] Don't unnecessarily drop LTR kerns when combining with RTL (#1041).
• [builder] Reorder .notdef and space glyphs in public.glyphOrder (#1038).

v6.9.2

• Fix some issues with style linking and naming of 'Oblique' fonts (#1034).
• Synched GlyphData.xml with schriftgestalt/GlyphsInfo@baff52 (#1035).
• Skip 'disabled' custom parameters when glyphs=>ufo and minimal=True (#1036).
• [propagate_anchors] Fixed regression whereby the context of contextual anchors as stored in the anchor.userData was not being copied while propagating (#1037).

v6.9.1

• Support fonts named Oblique instead of Italic (#1034)
• Fix script cyrillic, fix name delonglegged-cy (#1035)
• skip disabled custom parameters when glyphs=>ufo and minimal=True (#1036)
• propagate_anchors: fix handling of contextual anchors (#1037)

v6.9.0

• Drop disabled prefixes, classes, and features in minimal mode (#1027)
• Fix the order of feature writers (#1025)
• Update GlyphsData.xml Latin and Cyrillic to Unicode 16 (#1008)
• Allow GSFont object to be passed to build_masters directly (in place of a path) (#1029)
• markFeatureWriter: Use new ufo2ft MarkFeatureWriter (#1030)

v6.8.2

Fixed infinite loop when propagating anchors and composite glyphs contain cyclical component references (#1022, #1023).

v6.8.1

Fixed a regression introduced in v6.8.0 when the optional glyph_data parameter is passed to to_designspace and to_ufos functions. This corresponds to fontmake's --glyph-data CLI flag, and consists in a list of paths to custom GlyphData.xml files. After v6.8.0, an AttributeError: 'list' object has no attribute 'names' exception was raised when the parameter was set (#1019, #1020).

v6.8.0

• Rewrote composite glyphs' anchor propagation logic to better match the built-in Glyphs.app feature. This is based on the Rust implementation in fontc, in turn based on the original Objective-C code which was shared with us privately. It fixes various issues with anchor propagation (#368, #1011). Note that currently only 'master' layers have their anchors propagated (not unlike the old code which this replaces, see #1017).

v6.7.2

• markFeatureWriter: optimize contextual mark positioning lookups (#1010)
• GSGlyph: fix iterating over layers of orphan glyphs (#1013)
• GSLayer: fix name property when parent GSGlyph is in turn orphan (#1014)

v6.7.1

• Stops brace layers inheriting width linking from their masters (#985)
• Adds some test cases for deriving categories from glyphs with complex names (#1000)

v6.7.0

• Removed resolve_intermediate_components from the preflight stage, since this is no longer needed now that ufo2ft v3.2.0 will handle this at build time (only if/when actually needed).
