  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="http://wiki.freedesktop.org/wiki/Software/gallium"
  27 target="_parent">Gallium3D</a> infrastructure.
  28 </p>
  29 <p>
  30 Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by
  31 glGetString(GL_VERSION) depends on the particular driver being used.
  32 Some drivers don't support all the features required in OpenGL 2.1.
  33 </p>
  34 <p>
  35 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
  36 for DRI hardware acceleration.
  37 </p>
  38 <p>
  39 Note that the Mesa project is no longer using odd/even version numbers
  40 to indicate development/stable releases.
  41 The so-called development releases have been fairly stable.
  42 If you're especially concerned with stability you should probably look for
  43 "point" releases such as 7.5.1 which will be a bug-fix release.

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