Mesa 9.0 Release Notes / date TBD

Mesa 9.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 9.0.1.

Mesa 9.0 implements the OpenGL 3.1 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 3.1. OpenGL 3.1 is only available if requested at context creation because GL_ARB_compatibility is not supported.

New features

Note: some of the new features are only available with certain drivers.

• Added new Gallium3D - nv30 driver
• Added new Gallium3D - radeonsi driver
• Added OpenCL state tracker Clover
• Completed VDPAU state tracker (video decoding support is currently limited to MPEG1 and MPEG2)
• GL_ARB_base_instance
• GL_ARB_blend_func_extended
• GL_ARB_debug_output
• GL_ARB_invalidate_subdata - Currently a "no-op" implementation. This extension is always enabled in all drivers.
• GL_ARB_shader_bit_encoding
• GL_ARB_texture_buffer_object
• GL_ARB_timer_query
• GL_ARB_transform_feedback3
• GL_ARB_transform_feedback_instanced
• GL_ARB_uniform_buffer_object
• GL_EXT_unpack_subimage for ES 2.0
• GL_EXT_read_format_bgra for ES 1.1 and 2.0
• GL_EXT_texture_rg for ES 2.x
• GL_NV_read_buffer for ES 2.0
• GLX_ARB_create_context_robustness
• EGL_KHR_create_context
• EGL_KHR_surfaceless_context - This replaces the EGL_KHR_surfaceless_{gles1,gles2,opengl} extensions that were never approved by Khronos.
• EGL_EXT_create_context_robustness

Bug fixes

TBD -- This list is likely incomplete.

Changes

• The legacy/static Makefile system (ex: 'make linux-dri') has been removed.
  The two supported build methods are now autoconf/automake and SCons.
• Removed support for GL_ARB_shadow_ambient extension
• Removed Gallium3D - nvfx driver (use nv30 instead)

libGLU has been moved into its own repository, found at http://cgit.freedesktop.org/mesa/glu/
