Mesa 7.9 Release Notes / date TBD

Mesa 7.9 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 7.9.1.

Mesa 7.9 implements the OpenGL 2.1 API, but the version reported by glGetString(GL_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 2.1.

See the Compiling/Installing page for prerequisites for DRI hardware acceleration.

New features

New, improved GLSL compiler written by Intel. See the Shading Language page for more information.
New, very experimental Gallium driver for R600-R700 Radeons.
Support for AMD Evergreen-based Radeons (HD 5xxx)
GL_EXT_timer_query extension (i965 driver and softpipe only)
GL_EXT_framebuffer_multisample extension (intel drivers, MAX_SAMPLES = 1)
GL_ARB_texture_swizzle extension (alias of GL_EXT_texture_swizzle)
GL_ARB_draw_elements_base_vertex, GL_ARB_fragment_program_shadow, GL_ARB_window_pos, GL_EXT_gpu_program_parameters, GL_ATI_texture_env_combine3, GL_MESA_pack_invert, and GL_OES_EGL_image extensions in Gallium drivers
GL_ARB_depth_clamp and GL_NV_depth_clamp extensions (in nv50 and r600 Gallium drivers)
GL_ARB_half_float_vertex extension (in nvfx, r300, r600, softpipe, and llvmpipe Gallium drivers)
GL_EXT_draw_buffers2 (in nv50, r600, softpipe, and llvmpipe Gallium drivers)
GL_EXT_texture_swizzle (in nvfx, r300, r600, softpipe, and llvmpipe Gallium drivers)
GL_ATI_texture_mirror_once (in nvfx, nv50, r300, r600, softpipe, and llvmpipe Gallium drivers)
GL_NV_conditional_render (in r300 Gallium driver)
Initial "signs of life" support for Sandybridge hardware in i965 DRI driver.

Bug fixes

This list is likely incomplete.

Massive improvements to the Gallium driver for R300-R500 Radeons; this driver is now considered stable for use as a DRI (OpenGL) driver.
