Highlights

HarfBuzzSharp 14.2.0 ships with SkiaSharp 4.148.0 and delivers variable font support, a new HBColor struct, a reworked singleton lifecycle, and expanded platform coverage. OpenType variable-font axis APIs land in both HBFace and HBFont, and the lifecycle of singleton native objects is now ref-counted and crash-free. Community contributors @ramezgerges and @4Darmygeometry drove the major features and Linux Bionic support.

New Features

  • HBColor struct — Proper managed type for hb_color_t, enabling correct color glyph API usage. (#4000)
  • Variable font support — Adds HBFace and HBFont variable-instance APIs for full OpenType font variation axis access. ❤️ @ramezgerges (#3703)
  • Color font palette support — Improved color palette handling for color and emoji fonts. (#3742)

Bug Fixes

  • Reworked singleton lifecycle — Singleton native objects now use a proper ref-counted lifecycle, preventing use-after-free crashes in HarfBuzz singleton instances. ❤️ @ramezgerges (#4080)

Platform

  • Linux Bionic native assets — Prebuilt HarfBuzzSharp natives for Android Bionic libc on Linux. ❤️ @4Darmygeometry (#3217)
  • Tizen x64 and ARM64 native builds (#3620)
  • WASM: Dropped pre-.NET 8 Emscripten builds (#4022)
