- Update from version 4.2.0 to 4.4.1 - Update of rootfile - Changelog Overview of changes leading to 4.4.1 - Fix test failure with some compilers. - Fix Telugu and Kannada kerning regression. Overview of changes leading to 4.4.0 - Caching of variable fonts shaping, in particular when using HarfBuzz’s own font loading functions (ot). Bringing performance of variable shaping in par with non-variable fonts shaping. (Behdad Esfahbod) - Caching of format 2 “Contextual Substitution” and “Chained Contexts Substitution” lookups. Resulting in up to 20% speedup of lookup-heavy fonts like Gulzar or Noto Nastaliq Urdu. (Behdad Esfahbod) - Improved ANSI output from hb-view. (Behdad Esfahbod) - Support for shaping legacy, pre-OpenType Windows 3.1-era, Arabic fonts that relied on a fixed PUA encoding. (Khaled Hosny, Behdad Esfahbod) - Sinhala script is now shaped by the USE shaper instead of “indic” one. (Behdad Esfahbod, David Corbett) - Thai shaper improvements. (David Corbett) - hb-ot-name API supports approximate BCP-47 language matching, for example asking for “en_US” in a font that has only “en” names will return them. (Behdad Esfahbod) - Optimized TrueType glyph shape loading. (Behdad Esfahbod) - Fix subsetting of HarfBuzz faces created via hb_face_create_for_tables(). (Garret Rieger) - Add 32 bit var store support to the subsetter. (Garret Rieger) - New API +HB_BUFFER_FLAG_DEFINED +HB_BUFFER_SERIALIZE_FLAG_DEFINED +hb_font_changed() +hb_font_get_serial() +hb_ft_hb_font_changed() +hb_set_hash() +hb_map_copy() +hb_map_hash() Overview of changes leading to 4.3.0 - Major speed up in loading and subsetting fonts, especially in handling CFF table. Subsetting some fonts is now 3 times faster. (Behdad Esfahbod, Garret Rieger) - Speed up blending CFF2 table. (Behdad Esfahbod) - Speed up hb_ot_tags_from_language(). (Behdad Esfahbod, David Corbett) - Fix USE classification of U+10A38 to fix multiple marks on single Kharoshthi base. (David Corbett) - Fix parsing of empty CFF Index. (Behdad Esfahbod) - Fix subsetting CPAL table with partial palette overlaps. (Garret Rieger) - New API +hb_map_is_equal() (Behdad Esfahbod) Overview of changes leading to 4.2.1 - Make sure hb_blob_create_from_file_or_fail() always returns nullptr in case of failure and not empty blob sometimes. (Khaled Hosny) - Add --passthrough-tables option to hb-subset. (Cosimo Lupo) - Reinstate a pause after basic features in Khmer shaper, fixing a regression introduced in previous release. (Behdad Esfahbod) - Better handling of Regional_Indicator when shaped with RTL-native scripts, reverting earlier fix that caused regressions in AAT shaping.
