v3.5.0

• [instantiator] support 'public.fontInfo' lib key in designspace instance <lib> element when interpolating instance UFOs (#918, googlefonts/fontmake#953).

v3.4.6

• [postProcessor] don't overwrite a VF's default weight/width/slant (#916).
• [markFeatureWriter] Consolidate how we consider a mark contextual (#912).
• stemSnapH and stemSnapV values must be in ascending order (#913).

v3.4.5

• [markFeatureWriter] Don't trip over anchors with an identifier but without optional glyph.lib['public.objectLibs'] (#911).

v3.4.4

• [outlineCompiler] Fixed KeyError while building cmap14 subtable when UVS
  code point is not present in the main Unicode cmap. In fact, this is not required,
  and it may be desired that a given Unicode character only occurs in a variation
  sequence, so the requirement was relaxed (#909).
• [infoCompiler] Remove superfluous nameID 16/17 when they can be omitted after having
  applied the name table overrides from public.fontInfo lib key (#906).

v3.4.3

• Pass feaIncludeDir to variable feature compiler (#904).

v3.4.2

• Fixed bug whereby OS/2 codepage range bits weren't correctly computed for variable fonts (all unset except fallback bit 0).
  This happened when a designspace contained a <variable-font> element with a 'public.fontInfo' lib key that did not explicitly override openTypeOS2CodePageRanges (#897).

v3.4.1

Fixed typos in USE_SCRIPTS list of ISO script tags for USE-enabled scripts: Bhaiksuki -> "Bhks" (not "Nhks"), N'ko -> "Nkoo" (not "Nko ").

They should now get 'dist' feature instead of 'kern', and 'abvm' and
'blwm' instead of 'mark', like the other USE_SCRIPTS (#896).

v3.4.0

• [postProcessor] fontTools.varLib.cff.convertCFFtoCFF2 is deprecated (#882)
• [outlineCompiler] Warn when building COLRv0 if gid1 is not blank (#886)
• [instantiator] Use designspace.findDefault() the first time designspace.default is checked (#887)
• [markFeatureWriter] Fix ligatures with unnumbered contextual anchors having their mark attachment dropped (#890)
• [markFeatureWriter] Support contextual mark2mark anchors (#895)
• [markFeatureWriter] Drop “ambiguously connected” info message (#892)
• [removeOverlaps] Capture TypeError and ValueError that pathops and booleanOperations might raise (#492)
• [doc] Document lib keys modifying ufo2ft's behavior (#286)

v3.3.1

• [featureWriters] Support insert marker in the middle of a feature block (#873)
• [cursFeatureWriter] Respect direction suffix when setting lookupflag (#876)

v3.3.0

• Rewrite old kern writer to pull in some changes made in the newer one (#870)
• markFeatureWriter: Support contextual anchors (#869)
• markFeatureWriter: Support contextual ligature anchors (#871)
