Overview of changes leading to 14.5.0
Monday, September 21, 2026
=====================================
- Update Unicode 18.0 data and script support, including script values for
Jurchen, Proto-Cuneiform, and Seal, and the corresponding shaping support.
- Add support for VARC table subsetting, including pruning auxiliary data,
remapping glyph IDs, and guarding the feature in lean builds.
- Add rendering work budgets to the draw and paint APIs and share them across
the raster, vector, GPU, and Cairo renderers so nested outline work remains
bounded.
- Improve performance in set iteration, lookup traversal, and the repacker, and
add coverage for new benchmarks and fuzzing seeds.
- Fix various correctness and robustness issues across the CFF, Graphite,
DirectWrite, and repacker code paths, including memory leaks, overflow checks,
bounds issues, and malformed-font handling.
- Various build, portability, and CI fixes.
- New API:
* Common:
+HB_BUDGET_DEFAULT
+HB_BUDGET_UNLIMITED
+HB_SCRIPT_JURCHEN
+HB_SCRIPT_PROTO_CUNEIFORM
+HB_SCRIPT_SEAL
* Draw:
+hb_draw_set_budget_func_t
+hb_draw_get_budget_func_t
+hb_draw_get_budget_remaining_func_t

+hb_draw_funcs_set_get_budget_remaining_func()
+hb_draw_set_budget()
+hb_draw_get_budget()
+hb_draw_get_budget_remaining()
* Paint:
+hb_paint_set_budget_func_t
+hb_paint_get_budget_func_t
+hb_paint_get_budget_remaining_func_t
+hb_paint_funcs_set_set_budget_func()
