## Highlights

SkiaSharp 4.133.0 is the first major version bump to 4.x, powered by Skia m133. This release introduces full variable font support with color font palettes, new platform targets for Android Bionic and Tizen, sampling options for surface drawing, and updated native dependencies. Community contributors [@ramezgerges](https://github.com/ramezgerges), [@4Darmygeometry](https://github.com/4Darmygeometry), and [@SimonvBez](https://github.com/SimonvBez) drove key features and fixes across the release.
SkiaSharp 4.133.0 is the first major version bump to 4.x, powered by Skia m133. This release introduces full variable font support with color font palettes, new platform targets for Android Bionic and Tizen (including Studio 6.1 and TFM support), sampling options for surface drawing, and a critical Windows fix that eliminates startup crashes on systems without DX12. Updated native dependencies harden the build against known CVEs.

## Bug Fixes

- **Fixed D3D12 startup crashes on systems without DX12** — `libSkiaSharp.dll` previously hard-linked `d3d12.dll`, `dxgi.dll`, and `D3DCOMPILER_47.dll`, causing crashes at startup on Windows 7/8, some Windows 10 machines, and Windows Server 2008. These DLLs are now delay-loaded, so they are only loaded when GPU rendering is explicitly requested. ([#3633](https://github.com/mono/SkiaSharp/pull/3633))
- **Fixed design-time detection in Windows Forms controls** — Removes the stale cached `designMode` field from `SKControl` and `SKGLControl`, using the built-in `DesignMode` property for correct design-time behavior. ([#3614](https://github.com/mono/SkiaSharp/pull/3614))
- **Fixed SKGLView on Android not rendering with TabBar** — Resolves an issue where `SKGLView` would not render when used inside a tab bar on Android. ❤️ [@SimonvBez](https://github.com/SimonvBez) ([#3076](https://github.com/mono/SkiaSharp/pull/3076))
- **Fixed x86 .NET Framework threading test OOM failures** — Resolves out-of-memory crashes in threading tests on 32-bit .NET Framework. ([#3674](https://github.com/mono/SkiaSharp/pull/3674))
- **Fixed Debian 13 Docker build** — Corrects native build failures for non-loong64/riscv64 architectures on Debian 13. ([#3747](https://github.com/mono/SkiaSharp/pull/3747))
