| <H1>Mesa 7.5 Release Notes / date TBD</H1> |
| |
| <p> |
| Mesa 7.5 is a new development release. |
| People who are concerned with stability and reliability should stick |
| with the 7.4.x branch or wait for Mesa 7.5.1. |
| </p> |
| <p> |
| The main new feature of Mesa 7.5 is the |
| <a href="http://www.tungstengraphics.com/wiki/index.php/Gallium3D" |
| target="_parent">Gallium3D</a> infrastructure. |
| </p> |
| <p> |
| Mesa 7.5 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> |
| <p> |
| Note that the Mesa project is no longer using odd/even version numbers |
| to indicate development/stable releases. |
| The so-called development releases have been fairly stable. |
| If you're especially concerned with stability you should probably look for |
| "point" releases such as 7.5.1 which will be a bug-fix release. |

| <h2>New features</h2> |
| <ul> |
| <li>Gallium3D - this is the new architecture for OS-independent and |
| API-independent 3D drivers. |
| Gallium3D is intended for GPUs that fully support vertex/fragment shaders. |
| The Gallium3D drivers currently included are: |
| <ul> |
| <li>softpipe - a software/reference driver |
| <li>i915 - Intel 915/945 driver |
| <li><a href="cell.html">Cell</a> - IBM/Sony/Toshiba Cell processor driver |
| <li>nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300). |
| <b>PLEASE NOTE: these drivers are incomplete and still under development. |
| It's probably NOT worthwhile to report any bugs unless you have patches. |
| </b> |
| </ul> |
| <li>GL_ARB_framebuffer_object extension (software drivers, i965 driver) |
| <li>Reworked two-sided stencil support. |
| This allows a driver to support all three variations of two-sided stencil |
| including GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0 |
| <li>GL_EXT_vertex_array_bgra extension (software drivers, i965 driver) |
| <li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers) |
| <li>GL_EXT_texture_swizzle extension (software drivers, i965 driver) |
| <li>Updated SPARC assembly optimizations (David S. Miller) |
| <li>Initial support for separate compilation units in GLSL compiler. |
| </ul> |
| |
| |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>Lots of i965 driver bug fixes |
| </ul> |
| |
| |
| <h2>Changes</h2> |
| <ul> |
| <li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and |
| GL_SGIX_depth_texture extensions. Superseded by the ARB versions. |
| <li>Omitted some old Mesa demos from the release tarballs, added some others. |
| </ul> |
