  11 <H1>Mesa 7.5 Release Notes / 17 July 2009</H1>
  12
  13 <p>
  14 Mesa 7.5 is a new development release.
  15 People who are concerned with stability and reliability should stick
  16 with the 7.4.x branch or wait for Mesa 7.5.1.
  17 </p>
  18 <p>
  19 The main new feature of Mesa 7.5 is the
  20 <a href="http://wiki.freedesktop.org/wiki/Software/gallium"
  21 target="_parent">Gallium3D</a> infrastructure.
  22 </p>
  23 <p>
  24 Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by
  25 glGetString(GL_VERSION) depends on the particular driver being used.
  26 Some drivers don't support all the features required in OpenGL 2.1.
  27 </p>
  28 <p>
  29 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
  30 for DRI hardware acceleration.
  31 </p>
  32 <p>
  33 Note that the Mesa project is no longer using odd/even version numbers
  34 to indicate development/stable releases.
  35 The so-called development releases have been fairly stable.
  36 If you're especially concerned with stability you should probably look for
  37 "point" releases such as 7.5.1 which will be a bug-fix release.

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