Overview of changes leading to 3.3.0
Monday, January 31, 2022
====================================
- Improved documentation. (Matthias Clasen)
- Internal code cleanup, using C++ standard library more. (Behdad Esfahbod)
- The low 16-bits of face index will be used by hb_face_create() to select a
face inside a font collection file format, while the high 16-bits will be
used by hb_font_create() to load the named instance. (Behdad Esfahbod)
- Glyph positions and other font metrics now apply synthetic slant set by
hb_font_set_synthetic_slant(), for improved positioning for synthetically
slanted fonts. (Behdad Esfahbod)
- Fixed unintentional locale dependency in hb_variation_to_string() for decimal
point representation. (Matthias Clasen)
- When applying pair positioning (kerning) the positioning value is split
between the two sides of the pair for improved cursor positioning between
such pairs. (Behdad Esfahbod)
- Introduced new HB_GLYPH_FLAG_UNSAFE_TO_CONCAT, to be used in conjunction
with HB_GLYPH_FLAG_UNSAFE_TO_BREAK for optimizing re-shaping during line
breaking. Check the documentation for further details. (Behdad Esfahbod)
- Improved handling of macrolanguages when mapping BCP 47 codes to OpenType
tags. (David Corbett)
- New API:
+HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
+hb_segment_properties_overlay()
+hb_buffer_create_similar()
+hb_font_set_synthetic_slant()
+hb_font_get_synthetic_slant()
+hb_font_get_var_coords_design()
Overview of changes leading to 3.2.0
Friday, November 26, 2021
====================================
"harfbuzz" library improvements:
- Fixed shaping of Apple Color Emoji flags in right-to-left context. (Behdad Esfahbod)
- Fixed positioning of CFF fonts in HB_TINY profile. (Behdad Esfahbod)
- OpenType 1.9 language tags update. (David Corbett)
- Add HB_NO_VERTICAL config option.
- Add HB_CONFIG_OVERRIDE_H for easier configuration. (Behdad Esfahbod)
"harfbuzz-subset" library improvements:
- Improved packing of cmap, loca, and Ligature tables. (Garret Rieger)
- Significantly improved overflow-resolution strategy in the repacker. (Garret Rieger)
3.1.2
hb-shape / hb-view: revert treating text on the commandline as single paragraph (was introduced in 3.0.0); add new --single-par to do that.
Subsetter bug fixes.
Overview of changes leading to 2.8.1
Tuesday, May 4, 2021
====================================
- Subsetter now fully supports GSUB/GPOS/GDEF tables (including variations); as
such, layout tables are retained by subsetter by default. (Garret Rieger, Qunxin Liu)
- Build scripts no longer check for FontConfig as HarfBuzz does not use it.
- hb-view supports iTerm2 and kitty inline image protocols (Khaled Hosny),
it can also use Chafa for terminal graphics if available (Hans Petter Jansson).
Overview of changes leading to 2.8.0
Tuesday, March 16, 2021
====================================
- Shape joining scripts other than Arabic/Syriac using the Universal Shaping Engine.
Previously these were shaped using the generalized Arabic shaper. (David Corbett)
- Fix regression in shaping of U+0B55 ORIYA SIGN OVERLINE. (David Corbett)
- Update language tags. (David Corbett)
- Variations: reduce error: do not round each interpolated delta. (Just van Rossum)
- Documentation improvements. (Khaled Hosny, Nathan Willis)
- Subsetter improvements: subsets most, if not all, lookup types now. (Garret Rieger,
Qunxin Liu)
- Fuzzer-found fixes and other improvements when memory failures happen. (Behdad)
- Removed most atomic implementations now that we have C++11 atomic impl. (Behdad)
- General codebase upkeep; using more C++11 features: constexpr constructors, etc.
(Behdad)
Changelog:
2.7.4
Fix missing --enable-introspection configure option from previous release tarball.
Documentation updates.
2.7.3
Update USE shaper to 2020-08-13 specification, and other improvements.
Don't disable liga feature in myanmar shaper, to match Uniscribe.
Improvements to language and script tags handling.
Update language system tag registry to OpenType 1.8.4
Support for serializing and deserializing Unicode buffers. Serialized buffers
are now delimited with <> or [] based on whether it is a Unicode or
glyphs buffer.
Increase buffer work limits to handle fonts with many complex lookups.
Handle more shaping operations in trace output.
Memory access fixes.
More OOM fixes.
Improved documentation.
Build system improvements.
New API:
+hb_buffer_has_positions()
+hb_buffer_serialize()
+hb_buffer_serialize_unicode()
+hb_buffer_deserialize_unicode()
Only a few pieces of software are using the ICU integration library,
these aren't the big harfbuzz users (i.e. gtk). this is intended to lessen
the impact of icu's frequent ABI breaks.
