<h1>Mesa 9.2 Release Notes / (date TBD)</h1>
<p>
Mesa 9.2 is a new development release.
People who are concerned with stability and reliability should stick
with a previous release or wait for Mesa 9.2.1.
</p>
<p>
Mesa 9.2 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 <strong>only</strong> available if requested at context creation
because GL_ARB_compatibility is not supported.

<h2>MD5 checksums</h2>

<h2>New features</h2>
<p>
Note: some of the new features are only available with certain drivers.
</p>
<ul>
<li>GL_ARB_shading_language_420pack</li>
<li>GL_ARB_texture_buffer_range</li>
<li>GL_ARB_texture_multisample</li>
<li>GL_ARB_texture_storage_multisample</li>
<li>GL_ARB_texture_query_lod</li>
<li>Enable GL_ARB_texture_storage on radeon, r200, and nouveau</li>
<li>Added new freedreno gallium driver</li>
<li>OSMesa interface for gallium llvmpipe/softpipe drivers</li>
<li>Gallium Heads-Up Display (HUD) feature for performance monitoring</li>
<li>Added support for UVD (2.2 and 3.0) video decoding on r600g and radeonsi through VDPAU (requires Kernel 3.10 or later)</li>
</ul>
<h2>Bug fixes</h2>
<p>TBD -- This list is likely incomplete.</p>
<h2>Changes</h2>
<ul>
<li>Removed d3d1x state tracker (unused, unmaintained and broken)</li>
<li>Removed GL_EXT_clip_volume_hint because no driver had enabled it since
2007.</li>
<li>Removed GL_MESA_resize_buffers because it was only really implemented by
the (unsupported) GDI driver.</li>
<li>GL_EXT_separate_shader_objects has been removed from all Gallium drivers,
because it disallows a critical GLSL shader optimization.
GL_ARB_separate_shader_objects doesn't have this issue.</li>
<li>i965 Gen6+ requires Kernel 3.6 or later. (92d2f5a)</li>
</ul>
