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

210Changes
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)
222
