| 17 | <h1>Mesa 7.5 Release Notes / 17 July 2009</h1>
|
|---|
| 18 |
|
|---|
| 19 | <p>
|
|---|
| 20 | Mesa 7.5 is a new development release.
|
|---|
| 21 | People who are concerned with stability and reliability should stick
|
|---|
| 22 | with the 7.4.x branch or wait for Mesa 7.5.1.
|
|---|
| 23 | </p>
|
|---|
| 24 | <p>
|
|---|
| 25 | The main new feature of Mesa 7.5 is the
|
|---|
| 26 | <a href="https://www.freedesktop.org/wiki/Software/gallium">Gallium3D</a> infrastructure.
|
|---|
| 27 | </p>
|
|---|
| 28 | <p>
|
|---|
| 29 | Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by
|
|---|
| 30 | glGetString(GL_VERSION) depends on the particular driver being used.
|
|---|
| 31 | Some drivers don't support all the features required in OpenGL 2.1.
|
|---|
| 32 | </p>
|
|---|
| 33 | <p>
|
|---|
| 34 | See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
|
|---|
| 35 | for DRI hardware acceleration.
|
|---|
| 36 | </p>
|
|---|
| 37 | <p>
|
|---|
| 38 | Note that the Mesa project is no longer using odd/even version numbers
|
|---|
| 39 | to indicate development/stable releases.
|
|---|
| 40 | The so-called development releases have been fairly stable.
|
|---|
| 41 | If you're especially concerned with stability you should probably look for
|
|---|
| 42 | "point" releases such as 7.5.1 which will be a bug-fix release.

| 60 | <h2>New features</h2>
|
|---|
| 61 | <ul>
|
|---|
| 62 | <li>Gallium3D - this is the new architecture for OS-independent and
|
|---|
| 63 | API-independent 3D drivers.
|
|---|
| 64 | Gallium3D is intended for GPUs that fully support vertex/fragment shaders.
|
|---|
| 65 | The Gallium3D drivers currently included are:
|
|---|
| 66 | <ul>
|
|---|
| 67 | <li>softpipe - a software/reference driver
|
|---|
| 68 | <li>i915 - Intel 915/945 driver
|
|---|
| 69 | <li>Cell - IBM/Sony/Toshiba Cell processor driver
|
|---|
| 70 | <li>nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300).
|
|---|
| 71 | <b>PLEASE NOTE: these drivers are incomplete and still under development.
|
|---|
| 72 | It's probably NOT worthwhile to report any bugs unless you have patches.
|
|---|
| 73 | </b>
|
|---|
| 74 | </ul>
|
|---|
| 75 | <li>GL_ARB_framebuffer_object extension (software drivers, i965 driver)
|
|---|
| 76 | <li>Reworked two-sided stencil support.
|
|---|
| 77 | This allows a driver to support all three variations of two-sided stencil
|
|---|
| 78 | including GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0
|
|---|
| 79 | <li>GL_EXT_vertex_array_bgra extension (software drivers, i965 driver)
|
|---|
| 80 | <li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers)
|
|---|
| 81 | <li>GL_EXT_texture_swizzle extension (software drivers, i965 driver)
|
|---|
| 82 | <li>Updated SPARC assembly optimizations (David S. Miller)
|
|---|
| 83 | <li>Initial support for separate compilation units in GLSL compiler.
|
|---|
| 84 | <li>Increased max number of generic GLSL varying variables to 16 (formerly 8).
|
|---|
| 85 | <li>GLSL linker now detects when too many varying variables are used.
|
|---|
| 86 | <li>Optimize-out redundant glMaterial and glShadeModel calls in display lists
|
|---|
| 87 | <li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler.
|
|---|
| 88 | </ul>
|
|---|
| 89 |
|
|---|
| 90 |
|
|---|
| 91 | <h2>Bug fixes</h2>
|
|---|
| 92 | <ul>
|
|---|
| 93 | <li>Lots of i965 driver bug fixes
|
|---|
| 94 | <li>Fixed some GLSL preprocessor bugs
|
|---|
| 95 | <li>GLSL: continue inside of a for-loop didn't work
|
|---|
| 96 | </ul>
|
|---|
| 97 |
|
|---|
| 98 |
|
|---|
| 99 | <h2>Changes</h2>
|
|---|
| 100 | <ul>
|
|---|
| 101 | <li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and
|
|---|
| 102 | GL_SGIX_depth_texture extensions. Superseded by the ARB versions.
|
|---|
| 103 | <li>Omitted some old Mesa demos from the release tarballs, added some others.
