 Overview of changes leading to 14.2.1
 Tuesday, June 2, 2026

 - Various AAT shaping fixes: legacy `mort` contextual offsets (which could
   produce out-of-font glyph IDs), in-place deleted-glyph replacements, and
   overflow in obsolete offset math.
 - Fix Arabic PUA fallback shaping for the isolated lam-alef-maksura
 ligature.
 - Fix float-to-int overflow in `avar2` mapping with malformed fonts.
 - Harden buffer verification after detecting non-monotone clusters.
 - Various `COLR` v1 fixes: fix handling of `.notdef` without paint, round
 alpha
   consistently, and report the root clip under the font transform.
 - Various Glyph-extents fixes: inclusive rounding, and floating-point
 scaling
   before rounding so the reported box always covers the glyph.
 - Various Subsetting fixes: keep the `palt` spacing feature by default,
 raise
   the repacker `MAX_SPACES` limit, fix a repacker crash on shared
 `LigatureSet`
   nodes, guard `gvar` size overflow on 32-bit, and fix the `post` glyph-
 name
   sort comparator on macOS.
 - Replace `std::sort` with an internal quicksort, removing leaked `std::`
   symbols from the `libharfbuzz` ABI.
 - Harden size computations with saturating arithmetic against 32-bit
 overflow.
 - Various improvements to the experimental Rust shaper (HarfRust) and font
   functions (`fontations`): honor custom font funcs, key shape plans on
   features, faster buffer handling, and update to HarfRust 0.8.
 - Various fixes to the experimental `harfbuzz-gpu` and `harfbuzz-vector`
   libraries, including a `harfbuzz-vector` heap buffer overflow and
 Windows
   build fixes.
 - Map the `Hrkt` (Katakana or Hiragana) script tag to the `kana` OpenType
 tag.
 - Build configuration: new `HB_CONFIG_OVERRIDE_LAST_H` override header,
   decouple `HB_NO_DRAW` from `HB_NO_CFF`, and an optional `hb-allocator`
 Cargo
   feature.
 - Various build, CI, and fuzzing fixes.
