+Overview of changes leading to 4.0.0
+Tuesday, March 1, 2022
+====================================
+- New public API to create subset plan and gather information on things like
+ glyph mappings in the final subset. The plan can then be passed on to perform
+ the subsetting operation. (Garret Rieger)
+- Draw API for extracting glyph shapes have been extended and finalized and is
+ no longer an experimental API. The draw API supports glyf, CFF and CFF2
+ glyph outlines tables, and applies variation settings set on the font as well
+ as synthetic slant. The new public API is not backward compatible with the
+ previous, non-public, experimental API. (Behdad Esfahbod)
+- The hb-view tool will use HarfBuzz draw API to render the glyphs instead of
+ cairo-ft when compiled with Cairo 1.17.5 or newer, setting HB_DRAW
+ environment variable to 1 or 0 will force using or not use the draw API,
+ respectively. (Behdad Esfahbod)
+- The hb-shape and hb-view tools now default to using HarfBuzz’s own font
+ loading functions (ot) instead of FreeType ones (ft). They also have a new
+ option, --font-slant, to apply synthetic slant to the font. (Behdad Esfahbod)
+- HarfBuzz now supports more than 65535 (the OpenType limit) glyph shapes and
+ metrics. See https://github.com/be-fonts/boring-expansion-spec/issues/6 and
+ https://github.com/be-fonts/boring-expansion-spec/issues/7 for details.
+ (Behdad Esfahbod)
+- New API to get the dominant horizontal baseline tag for a given script.
+ (Behdad Esfahbod)
+- New API to get the baseline positions from the font, and synthesize missing
+ ones. As well as new API to get font metrics and synthesize missing ones.
+ (Matthias Clasen)
+- Improvements to finding dependencies on Windows when building with Visual
+ Studio. (Chun-wei Fan)
+- New buffer flag, HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT, that must be set
+ during shaping for HB_GLYPH_FLAG_UNSAFE_TO_CONCAT flag to be reliably
+ produced. This is to limit the performance hit of producing this flag to when
+ it is actually needed. (Behdad Esfahbod)
+- Documentation improvements. (Matthias Clasen)
