1Mesa 20.2.5 Release Notes / 2020-12-16 2====================================== 3 4Mesa 20.2.5 is a bug fix release which fixes bugs found since the 20.2.4 release. 5 6Mesa 20.2.5 implements the OpenGL 4.6 API, but the version reported by 7glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / 8glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. 9Some drivers don't support all the features required in OpenGL 4.6. OpenGL 104.6 is **only** available if requested at context creation. 11Compatibility contexts may report a lower version depending on each driver. 12 13Mesa 20.2.5 implements the Vulkan 1.2 API, but the version reported by 14the apiVersion property of the VkPhysicalDeviceProperties struct 15depends on the particular driver being used. 16 17SHA256 checksum 18--------------- 19 20:: 21 22 0ebec6a22660d83f5ed437a145dc703c9398cd1376143aef273ea85f9dc5dd98 mesa-20.2.5.tar.xz 23 24 25New features 26------------ 27 28- None 29 30 31Bug fixes 32--------- 33 34- Mesa 20.3.0 and older ATi/Radeon cards fails 35- Amber test NIR validation failed after spirv_to_nir 36- Amber test validate_phi_src 37- [RADV] broken stencil behaviour when using extended dynamic stencil state 38- [RADV] Some bindings seem broken with VK_DYNAMIC_STATE_VERTEX_INPUT_BINDING_STRIDE_EXT 39- ci: Missing needs: in radeonsi-stoney-\*?
