11 <H1>Mesa
7.9 Release Notes / date TBD
</H1>
14 Mesa
7.9 is a new development release.
15 People who are concerned with stability and reliability should stick
16 with a previous release or wait for Mesa
7.9.1.
19 Mesa
7.9 implements the OpenGL
2.1 API, but the version reported by
20 glGetString(GL_VERSION) depends on the particular driver being used.
21 Some drivers don't support all the features required in OpenGL
2.1.
24 See the
<a href=
"install.html">Compiling/Installing page
</a> for prerequisites
25 for DRI hardware acceleration.
29 <h2>MD5 checksums
</h2>
37 <li>New, improved GLSL compiler written by Intel.
38 See the
<a href=
"shading.html"> Shading Language
</a> page for
40 <li>GL_EXT_timer_query extension (i965 driver only)
41 <li>GL_EXT_framebuffer_multisample extension (intel drivers, MAX_SAMPLES =
1)
42 <li>GL_ARB_texture_swizzle extension (alias of GL_EXT_texture_swizzle)
43 <li>GL_ARB_draw_elements_base_vertex, GL_ARB_fragment_program_shadow
44 and GL_EXT_draw_buffers2 in Gallium drivers
45 <li>Initial
"signs of life" support for Sandybridge hardware in i965 DRI
52 <p>This list is likely incomplete.
