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/
