Hello everyone,


I'm happy to announce a new feature release, 22.3.0.


New features (in no particular order):
- GL_ARB_shader_clock on llvmpipe
- VK_KHR_shader_clock on lavapipe
- Mesa-DB, the new single file cache type
- VK_EXT_attachment_feedback_loop_layout on RADV, lavapipe
- VK_KHR_global_priority on RADV
- GL_KHR_blend_equation_advanced_coherent on zink
- VK_EXT_load_store_op_none on RADV
- VK_EXT_mutable_descriptor_type on RADV
- VK_EXT_shader_atomic_float on lvp
- VK_EXT_shader_atomic_float2 on lvp
- GL_NV_shader_atomic_float on llvmpipe
- VK_EXT_image_robustness on v3dv
- VK_EXT_extended_dynamic_state3 on lavapipe
- VK_EXT_extended_dynamic_state3 on RADV & anv
- VK_EXT_pipeline_robustness on v3dv
- Mali T620 on panfrost
- Shader disk cache on Panfrost
- support for R8G8B8, B8G8R8, R16G16B16 and 64-bit vertex buffer formats
  on RADV
- initial GFX11/RDNA3 support on RADV
- various ray tracing optimizations on RADV
- extendedDynamicState2PatchControlPoints on RADV
  (VK_EXT_extended_dynamic_state2 feature)
- Radeon Raytracing Analyzer integration (using RADV_RRA_* environment
  variables)
- OpenGL 4.5 on freedreno/a6xx (up from 3.3)
- VK_EXT_mesh_shader on ANV


A couple of notes for packagers:
- When building the Intel Vulkan driver with ray-tracing (using
  `-D intel-clc=enabled`, disabled by default), libclc is required
  (both as build and runtime dependency).
- Rusticl, the OpenCL implementation (`-D gallium-rusticl=true`,
  disabled by default), introduces a bunch of new dependencies.
  Make sure you read docs/rusticl.rst (https://docs.mesa3d.org/rusticl)
  if you're considering enabling it.


For now, no driver is enabled by default in Rusticl. See here for how
to enable them:
https://docs.mesa3d.org/envvars#rusticl-environment-variables


If you find any issues, please report them here:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/new


The next bugfix release is due in two weeks, on December 14th.


Cheers,
  Eric
