26.0.6 and 26.1.0-rc3

• Updated Mesa3D to 26.0.6.
• ARM64 binaries are provided by mmozeiko here.
• Support for x86 32-bit build in MinGW has been restored but without LLVM support to workaround #156 so no openclon12, llvmpipe or lavapipe and performance is much lower for software fallback emulated features aka. NIR lowering in zink and d3d12 (both OpenGL and VA-API).

Feedback info

• Windows 7 / Server 2008 R2 support remained in place for the time being as this poll results were 68% in favor of keeping support at release time.

Known issues

• MFT codecs fail to build with Windows SDK 10.0.28000;
• lavapipe crashes at runtime if linked with LLVM 22.

Build environment information

• Use a more reliable way of retrieving selected Windows SDK and Driver Kit versions.

Build script

• Python launcher: Keep retrying if py <version> -c "import sys; print(sys.executable)" fails otherwise this glitch wipes the virtual environment and rebuilding may cause unwanted package updates.*

Build environment changes

• MSVC 26.1.0-rc3 build
• MSVC 26.0.6 build*
