+Overview of changes leading to 4.2.0
+Wednesday, March 30, 2022
+====================================
+- Source code reorganization, splitting large hb-ot-layout files into smaller,
+ per-subtable ones under OT/Layout/*. Code for more tables will follow suit in
+ later releases. (Garret Rieger, Behdad Esfahbod)
+- Revert Indic shaper change in previous release that broke some fonts and
+ instead make per-syllable restriction of “GSUB” application limited to
+ script-specific Indic features, while applying them and discretionary
+ features in one go. (Behdad Esfahbod)
+- Fix decoding of private in gvar table. (Behdad Esfahbod)
+- Fix handling of contextual lookups that delete too many glyphs. (Behdad Esfahbod)
+- Make “morx” deleted glyphs don’t block “GPOS” application. (Behdad Esfahbod)
+- Various build fixes. (Chun-wei Fan, Khaled Hosny)
+
+- New API
++hb_set_next_many() (Andrew John)
+
+
+Overview of changes leading to 4.1.0
+Wednesday, March 23, 2022
+====================================
+- Various OSS-Fuzz fixes. (Behdad Esfahbod)
+- Make fallback vertical-origin match FreeType’s. (Behdad Esfahbod)
+- Treat visible viramas like dependent vowels in USE shaper. (David Corbett)
+- Apply presentation forms features and discretionary features in one go in
+ Indic shaper, which seems to match Uniscribe and CoreText behaviour.
+ (Behdad Esfahbod, David Corbett)
+- Various bug fixes.
+
+- New API
++hb_set_add_sorted_array() (Andrew John)
+
+
+Overview of changes leading to 4.0.1
+Friday, March 11, 2022
+====================================
+- Update OpenType to AAT mappings for “hist” and “vrtr” features.
+ (Florian Pircher)
+- Update IANA Language Subtag Registry to 2022-03-02. (David Corbett)
+- Update USE shaper to allow any non-numeric tail in a symbol cluster, and
+ remove obsolete data overrides. (David Corbett)
+- Fix handling of baseline variations to return correctly scaled values.
+ (Matthias Clasen)
+- A new experimental hb_subset_repack_or_fail() to repack an array of objects,
+ eliminating offset overflows. The API is not available unless HarfBuzz is
+ built with experimental APIs enabled. (Qunxin Liu)
+

+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)
