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.

+The main new feature of Mesa 7.5 is the

+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 Superseded by the ARB versions.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>
