Mesa 20.3.2 Release Notes / 2020-12-30
======================================

Mesa 20.3.2 is a bug fix release which fixes bugs found since the 20.3.1 release.

Mesa 20.3.2 implements the OpenGL 4.6 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.6. OpenGL
4.6 is **only** available if requested at context creation.
Compatibility contexts may report a lower version depending on each driver.

Mesa 20.3.2 implements the Vulkan 1.2 API, but the version reported by
the apiVersion property of the VkPhysicalDeviceProperties struct
depends on the particular driver being used.

- None


Bug fixes
---------

- \`gl_FragColor' undeclared (AMDGPU) - tested stable Mesa 20.1 and latest git for 20.3 (Game/Wine/Proton)
- Mesa considers the framebuffer with mixed 3D and 2D array attachments to be incomplete.
- Multiple buffer definitions bound to single OpDecorate::Binding break SPIR-V module.
- Intel driver segfaults on SPIR-V with OpArrayLength
