   1 Mesa 9.2 Release Notes / (August 27, 2013)
   2 ==========================================
   3
   4 Mesa 9.2 is a new development release. People who are concerned with
   5 stability and reliability should stick with a previous release or wait
   6 for Mesa 9.2.1.
   7
   8 Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by
   9 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  10 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
  11 used. Some drivers don't support all the features required in OpenGL
  12 3.1. OpenGL 3.1 is **only** available if requested at context creation
  13 because GL_ARB_compatibility is not supported.

 210 Changes
 211 -------
 212
 213 -  Removed d3d1x state tracker (unused, unmaintained and broken)
 214 -  Removed GL_EXT_clip_volume_hint because no driver had enabled it
 215    since 2007.
 216 -  Removed GL_MESA_resize_buffers because it was only really implemented
 217    by the (unsupported) GDI driver.
 218 -  GL_EXT_separate_shader_objects has been removed from all Gallium
 219    drivers, because it disallows a critical GLSL shader optimization.
 220    GL_ARB_separate_shader_objects doesn't have this issue.
 221 -  i965 Gen6+ requires Kernel 3.6 or later. (92d2f5a)
