| <h1>Mesa 7.9 Release Notes / October 4, 2010</h1> |
| |
| <p> |
| 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. |
| </p> |
| <p> |
| 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. |
| </p> |
| <p> |
| See the <a href="../install.html">Compiling/Installing page</a> for prerequisites |
| for DRI hardware acceleration. |
| </p> |

| <h2>New features</h2> |
| <ul> |
| <li>New, improved GLSL compiler written by Intel. |
| See the <a href="../shading.html"> Shading Language</a> page for |
| more information. |
| <li>New, very experimental Gallium driver for R600-R700 Radeons. |
| <li>Support for AMD Evergreen-based Radeons (HD 5xxx) |
| <li>GL_EXT_timer_query extension (i965 driver and softpipe only) |
| <li>GL_EXT_framebuffer_multisample extension (intel drivers, MAX_SAMPLES = 1) |
| <li>GL_ARB_texture_swizzle extension (alias of GL_EXT_texture_swizzle) |
| <li>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 |
| <li>GL_ARB_depth_clamp and GL_NV_depth_clamp extensions (in nv50 and r600 |
| Gallium drivers) |
| <li>GL_ARB_half_float_vertex extension (in nvfx, r300, r600, softpipe, |
| and llvmpipe Gallium drivers) |
| <li>GL_EXT_draw_buffers2 (in nv50, r600, softpipe, and llvmpipe Gallium |
| drivers) |
| <li>GL_EXT_texture_swizzle (in nvfx, r300, r600, softpipe, and llvmpipe |
| Gallium drivers) |
| <li>GL_ATI_texture_mirror_once (in nvfx, nv50, r300, r600, softpipe, and |
| llvmpipe Gallium drivers) |
| <li>GL_NV_conditional_render (in r300 Gallium driver) |
| <li>Initial "signs of life" support for Sandybridge hardware in i965 DRI |
| driver. |
| </ul> |
| |
| |
| <h2>Bug fixes</h2> |
| <p>This list is likely incomplete.</p> |
| <ul> |
| <li>Massive improvements to the Gallium driver for R300-R500 Radeons; this |
| driver is now considered stable for use as a DRI (OpenGL) driver. |
