Version 4.150.0

Upcoming release · In development · Not yet available on NuGet

API changes · HarfBuzzSharp 14.2.0

Highlights

Version 4.150.0 completes the v4 API migration by promoting all remaining pre-v4 obsolete APIs to compile errors and trimming stale enum members from the reference assembly — community contributor @ramezgerges drove that cleanup. The long-deprecated .NET Interactive (Polyglot Notebooks) support is also removed in this release. HarfBuzz 14.2.0 ships alongside SkiaSharp 4.150.0 — see the API changes above for binding details.

Breaking Changes

  • Pre-v4 API cleanup — All APIs deprecated during the v4 transition now produce compile errors instead of warnings, and stale enum members have been removed from the reference assembly. Update any remaining v3-style call sites to their v4 equivalents before upgrading. ❤️ @ramezgerges (#4195)
  • Polyglot Notebooks / .NET Interactive support removed — The deprecated .NET Interactive (Polyglot Notebooks) integration has been removed entirely. Migrate to a supported rendering surface before upgrading. (#4186)

New Features

Platform

  • Tizen native builds in Docker — Tizen native dependencies are now compiled inside a Docker container, making Tizen builds more reproducible and host-independent. (#4154)
