17848b8605Smrg<h1>Mesa 9.2 Release Notes / (August 27, 2013)</h1>
18848b8605Smrg
19848b8605Smrg<p>
20848b8605SmrgMesa 9.2 is a new development release.
21848b8605SmrgPeople who are concerned with stability and reliability should stick
22848b8605Smrgwith a previous release or wait for Mesa 9.2.1.
23848b8605Smrg</p>
24848b8605Smrg<p>
25848b8605SmrgMesa 9.2 implements the OpenGL 3.1 API, but the version reported by
26848b8605SmrgglGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
27848b8605SmrgglGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
28848b8605SmrgSome drivers don't support all the features required in OpenGL 3.1.  OpenGL
29848b8605Smrg3.1 is <strong>only</strong> available if requested at context creation
30848b8605Smrgbecause GL_ARB_compatibility is not supported.

212848b8605Smrg<ul>
213848b8605Smrg<li>Removed d3d1x state tracker (unused, unmaintained and broken)</li>
214848b8605Smrg<li>Removed GL_EXT_clip_volume_hint because no driver had enabled it since
215848b8605Smrg2007.</li>
216848b8605Smrg<li>Removed GL_MESA_resize_buffers because it was only really implemented by
217848b8605Smrgthe (unsupported) GDI driver.</li>
218848b8605Smrg<li>GL_EXT_separate_shader_objects has been removed from all Gallium drivers,
219848b8605Smrg    because it disallows a critical GLSL shader optimization.
220848b8605Smrg    GL_ARB_separate_shader_objects doesn't have this issue.</li>
221848b8605Smrg<li>i965 Gen6+ requires Kernel 3.6 or later. (92d2f5a)</li>
