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" target="_parent">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. </p> <h2>MD5 checksums</h2> <pre> 553fd956e544727f30fbe249619b6286 MesaLib-7.5.tar.gz 459f332551f6ebb86f384d21dd15e1f0 MesaLib-7.5.tar.bz2 8c02c0e17a9025250d20424ae32f5163 MesaLib-7.5.zip a188da2886fa5496ea0c2cda602b2eeb MesaDemos-7.5.tar.gz 398ee8801814a00e47f6c2314e3dfddc MesaDemos-7.5.tar.bz2 15a0c8ae013c54335a26335e1a98d609 MesaDemos-7.5.zip 81010147def5a644ba14f9bbb7a49a2a MesaGLUT-7.5.tar.gz baa7a1e850b6e39bae58868fd0684004 MesaGLUT-7.5.tar.bz2 265228418e4423fa328f2f5b7970cf08 MesaGLUT-7.5.zip </pre> <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> </body> </html>
