<h1>Mesa 7.5 Release Notes / 17 July 2009</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://wiki.freedesktop.org/wiki/Software/gallium">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>Cell - 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. |
<li>Increased max number of generic GLSL varying variables to 16 (formerly 8). |
<li>GLSL linker now detects when too many varying variables are used. |
<li>Optimize-out redundant glMaterial and glShadeModel calls in display lists |
<li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler. |
</ul> |
|
|
<h2>Bug fixes</h2> |
<ul> |
<li>Lots of i965 driver bug fixes |
<li>Fixed some GLSL preprocessor bugs |
<li>GLSL: continue inside of a for-loop didn't work |
</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> |
