• Lavapipe driver has added support for new extensions
• Preliminary Arm Mali Valhall OpenGL support in Panfrost
• Etnaviv Gallium3D driver for Vivante graphics IP adds asynchronous shader compilation using ARB_parallel_shader_compile
• Continuing work on the PowerVR open-source Vulkan driver merged earlier this year
