Changes

  • Reuse compatible HarfBuzz subfonts within each shaping call, reducing allocation and font-setup overhead.
  • Avoid redundant image-pool locking when releasing images and renderer contexts.
  • Batch threaded event-completion accounting to reduce synchronization overhead without changing worker wakeup policy or output ordering.
  • Correct Microsoft symbol-font base offsets, including fonts mapped outside the 0xF000 range, following the upstream fix.
  • Update FreeBSD CI to 14.4 and the compatible VM action release.

The three performance optimizations preserve rendered output. The symbol-font correction intentionally fixes previously incorrect rendering.

Downloads

  • libass-android-0.18.4.zip: Android static libraries.
  • libass-apple-xcframework-0.18.4.zip: Apple XCFramework package.

Validation

The pre-release source passed GitHub CI, Meson CI, emulated-architecture regression tests, and FreeBSD, NetBSD, OpenBSD, and OmniOS VM checks. The Haiku job remains blocked before compilation by a HaikuPorts package download failure (libunibreak_devel).
