Hello everyone,

I'm happy to announce a new feature release, Mesa 26.2.0!

Mesa is the open source 3D graphics library, which includes implementations of
Vulkan 1.4, OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.1, and more APIs.

One important note for packagers is that there is now a Mesa community
maintained libclc fork that is verified to pass the OpenCL CTS with
Mesa/Rusticl, and will fix bugs after an upstream libclc major release
branch goes EoL. The Mesa build system will pick it up when available,
and fall back to upstream libclc if not. This libclc fork is not
verified for any other usages or users of libclc outside of Mesa.

A few highlights since Mesa 26.1:
- Gamma, a new tool for inspecting acceleration structures and ray
  tracing dispatches, was added. Currently, only RADV is supported.
- NVK gained support for VK_EXT_mesh_shader.
- KosmicKrisp now exposes Vulkan 1.4

Users can expect the usual flurry of improvements across all drivers and
components, including these new extensions & features highlighted by their
developers (in no particular order):
- cl_khr_subgroup_rotate on radeonsi
- cl_khr_subgroup_rotate on iris
- VK_EXT_shader_uniform_buffer_unsized_array on panvk
