Overview of changes leading to 10.1.0
Tuesday, November 5, 2024
====================================
- Fix the sign of fallback vertical glyph advance (used when font has no
vertical advance data).
- Increase maximum “CFF” operands limit 20 times to support more complex fonts.
- Add “--face-loader” option to command line utilities.
- Support “COLR” v0 table in hb_font_get_glyph_extents().
- Add support for font functions that use Core Text APIs, similar to FreeType
font functions. This allows, for example, using drawing fonts that use the new
(and undocumented) “hvgl” table.
- Update IANA and OT language registries, as well ase USE data files.
- Fix build with ICU 76.
- Various compiler warnings and build fixes.
- Various subsetter fixes.
- New API:
+hb_face_create_or_fail()
+hb_face_create_from_file_or_fail()
+hb_coretext_face_create_from_file_or_fail()
+hb_coretext_font_set_funcs()
+hb_ft_face_create_from_file_or_fail()
Overview of changes leading to 10.0.1
Tuesday, September 24, 2024
====================================
- Relax sanitization checks for “morx” subtables to fix broken AAT shaping of
macOS 15.0 version of GeezaPro.
Overview of changes leading to 10.0.0
Monday, September 23, 2024
====================================
- Unicode 16.0.0 support.
- Various documentation fixes.
- Various build fixes.
- Add API to allow HarfBuzz client to set what glyph to use when a Unicode
Variation Selector is not supported by the font, which would allow the client
to customize what happens in this case, by using a different font for example.
- Add a callback to for “hb_face_t” for getting the list of table tags. This is
now used to make calling “hb_face_get_table_tags()” work on a faces created by
“hb_face_create_for_tables()” (e.g. faces returned by “hb_subset_or_fail()”).
- CGJ and Mongolian Variation Selectors are now ignored during glyph
positioning, previously they would block both glyph substitution and
positioning across them.
- Support cairo script as an output format for “hb-view” command line tool.
- Drop an optimization that would cause HarfBuzz not apply pair positioning
lookup subtables under certain circumstances, for compatibility with other
implementations that do apply these subtables.
- Subsetting will now fail if source font has no glyphs, so feeding the subsetter
invalid data will not silently return an empty face.
- If after partially instancing a font no variation data is left (the instance
is fully static), don’t consider this a failure.
- Workaround a Firefox bug in displaying SVGs generated be “hb-view” command
line tool under certain circumstances.
- Fix bug in macroman mapping for “cmap” table.
- Fix difference shaping output when HarfBuzz is built with with
“HB_NO_OT_RULESETS_FAST_PATH” enabled.
- Various subsetting and instancing fixes.
- Various fuzzing fixes.
- Add “with_libstdcxx” meson build option.
- New API:
+HB_SCRIPT_GARAY
+HB_SCRIPT_GURUNG_KHEMA
+HB_SCRIPT_KIRAT_RAI
+HB_SCRIPT_OL_ONAL
+HB_SCRIPT_SUNUWAR
+HB_SCRIPT_TODHRI
+HB_SCRIPT_TULU_TIGALARI
+hb_buffer_set_not_found_variation_selector_glyph()
+hb_buffer_get_not_found_variation_selector_glyph()
+hb_get_table_tags_func_t
+hb_face_set_get_table_tags_func()
Overview of changes leading to 9.0.0
Thursday, Jun 27, 2024
====================================
- HarfBuzz now the supports the proposed new OpenType “VARC” table. This
replaces the previously supported “Variable Composites” experimental feature.
“VARC” support is still experimental and it is not enabled unless HarfBuzz is
built with experimental APIs enabled:
https://github.com/harfbuzz/boring-expansion-spec/blob/main/VARC.md
- Autotools build system have been dropped. Meson is the only supported build
system in HarfBuzz going forward.
- Speed up “AAT” shaping for short words by up to 4%.
- Ignore unknown “CFF” operators.
- “hb_subset_input_keep_everything()” now keeps also non-unicode “name” table
records.

Overview of changes leading to 8.0.0
Sunday, July 9, 2023
====================================
- New, experimental, WebAssembly (WASM) shaper, that provides greater
flexibility over OpenType/AAT/Graphite shaping, using WebAssembly embedded
inside the font file. Currently WASM shaper is disabled by default and needs
to be enabled at build time. For details, see:
https://github.com/harfbuzz/harfbuzz/blob/main/docs/wasm-shaper.md
For example fonts making use of the WASM shaper, see:
https://github.com/harfbuzz/harfbuzz-wasm-examples
- Improvements to Experimental features introduced in earlier releases:
- Support for subsetting beyond-64k and VarComposites fonts.
- Support for instancing variable fonts with cubic “glyf” table.
- Many big speed optimizations:
- Up to 89% speedup loading variable fonts for shaping.
- Up to 88% speedup in small subsets of large (eg. CJK) fonts (both TTF and
OTF), essential for Incremental Font Transfer (IFT).
- Over 50% speedup in loading Roboto font for shaping.
- Up to 40% speed up in loading (sanitizing) complex fonts.
- 30% speed up in shaping Gulzar font.
- Over 25% speedup in glyph loading Roboto font.
- 10% speed up loading glyph shapes in VarComposite Hangul font.
- hb-hashmap optimizations & hashing improvements.
- New macro HB_ALWAYS_INLINE. HarfBuzz now inlines functions more aggressively,
which results in some speedup at the expense of bigger code size. To disable
this feature define the macro to just inline.
- New API:
+HB_CODEPOINT_INVALID
+hb_ot_layout_get_baseline2()
+hb_ot_layout_get_baseline_with_fallback2()
+hb_ot_layout_get_font_extents()

Overview of changes leading to 6.0.0
Friday, December 16, 2022
====================================
- A new API have been added to pre-process the face and speed up future
subsetting operations on that face. Provides up to a 95% reduction in
subsetting times when the same face is subset more than once.
For more details and benchmarks, see:
https://github.com/harfbuzz/harfbuzz/blob/main/docs/subset-preprocessing.md
(Garret Rieger, Behdad Esfahbod)
- Shaping have been speedup by skipping entire lookups when the buffer contents
don't intersect with the lookup. Shows up to a 10% speedup in shaping some
fonts. (Behdad Esfahbod)
- A new experimental feature, “Variable Composites” (enabled by passing
-Dexperimental_api=true to meson), is also featured in this release.
This technology enables drastic compression of fonts in the Chinese,
Japanese, Korean, and other writing systems, by reusing the OpenType Font
Variations technology for encoding “smart components” into the font.
The specification for these extensions to the font format can be found in:
https://github.com/harfbuzz/boring-expansion-spec/blob/glyf1/glyf1.md
A test variable-font with ~7160 Hangul syllables derived from the
NotoSerifKR-VF font has been built, with existing OpenType technology, as
well as with the new Variable Composites (VarComposites) technology. The
VarComposites font is over 90% smaller than the OpenType version of the font!
Both fonts can be obtained from the “smarties” repository:
https://github.com/behdad/smarties/tree/3.0/fonts/hangul/serif
When building HarfBuzz with experimental features enabled, you can test
the “smarties” font with a sample character like this:
$ hb-view butchered-hangul-serif-smarties-variable.ttf -u AE01 --variations=wght=700
(Behdad Esfahbod)
- The HarfBuzz subsetter can now drop axes by pinning them to specific values
(also referred to as instancing). There are a couple of restrictions
currently:
- Only works with TrueType (“glyf”) based fonts. “CFF2” fonts are not yet
supported.
- Only supports the case where all axes in a font are pinned.
(Garret Rieger, Qunxin Liu)
- Miscellaneous fixes and improvements.
