Mesa 9.0 Release Notes / October 8, 2012
========================================

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
   https://cgit.freedesktop.org/mesa/glu/
