Overview of changes leading to 4.4.0
Monday, June 27, 2022
-
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)
-

+hb_font_changed()
