Overview of changes leading to 7.0.0
- New hb-paint API that is designed mainly to paint “COLRv1” glyphs, but can be
  also used as a unified API to paint any of the glyph representations
  supported by HarfBuzz (B/W outlines, color layers, or color bitmaps).
  (Behdad Esfahbod, Matthias Clasen)
- New hb-cairo API for integrating with cairo graphics library. This is provided
  as a separate harfbuzz-cairo library. (Behdad Esfahbod, Matthias Clasen)
- Support for instancing “CFF2” table. (Behdad Esfahbod)
- Support font emboldening. (Behdad Esfahbod)
- Support feature ranges with AAT shaping. (Behdad Esfahbod)
- Experimental support to cubic curves in “glyf” table, see
  https://github.com/harfbuzz/boring-expansion-spec/blob/main/glyf1-cubicOutlines.md
  for spec. (Behdad Esfahbod)
- Various subsetter improvements. (Garret Rieger, Qunxin Liu, Behdad Esfahbod)
- Various documentation improvements.
  (Behdad Esfahbod, Matthias Clasen, Khaled Hosny)
- Significantly reduced memory use during shaping. (Behdad Esfahbod)
- Greatly reduced memory use during subsetting “CFF” table. (Behdad Esfahbod)
- New command line utility, hb-info, for querying various font information.
  (Behdad Esfahbod, Matthias Clasen)
- New hb-shape/hb-view options: --glyphs, --color-palette, --font-bold,
  --font-grade, and --named-instance. (Behdad Esfahbod)
- Miscellaneous fixes and improvements.
