| Mesa 7.5 Release Notes / 17 July 2009 |
| ===================================== |
| |
| 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 |
| `Gallium3D <https://www.freedesktop.org/wiki/Software/gallium>`__ |
| infrastructure. |
| |
| 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. |
| |
| See the :doc:`Compiling/Installing page <../install>` for |
| prerequisites for DRI hardware acceleration. |
| |
| 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. |

| New features |
| ------------ |
| |
| - 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: |
| |
| - softpipe - a software/reference driver |
| - i915 - Intel 915/945 driver |
| - Cell - IBM/Sony/Toshiba Cell processor driver |
| - nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300). |
| |
| .. note:: |
| |
| these drivers are incomplete and still under development. |
| It's probably NOT worthwhile to report any bugs unless you have |
| patches. |
| |
| - GL_ARB_framebuffer_object extension (software drivers, i965 driver) |
| - 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 |
| - GL_EXT_vertex_array_bgra extension (software drivers, i965 driver) |
| - GL_NV_texture_env_combine4 extension (software drivers, i965/i915 |
| drivers) |
| - GL_EXT_texture_swizzle extension (software drivers, i965 driver) |
| - Updated SPARC assembly optimizations (David S. Miller) |
| - Initial support for separate compilation units in GLSL compiler. |
| - Increased max number of generic GLSL varying variables to 16 |
| (formerly 8). |
| - GLSL linker now detects when too many varying variables are used. |
| - Optimize-out redundant glMaterial and glShadeModel calls in display |
| lists |
| - Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler. |
| |
| Bug fixes |
| --------- |
| |
| - Lots of i965 driver bug fixes |
| - Fixed some GLSL preprocessor bugs |
| - GLSL: continue inside of a for-loop didn't work |
| |
| Changes |
| ------- |
| |
| - Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and |
| GL_SGIX_depth_texture extensions. Superseded by the ARB versions. |
| - Omitted some old Mesa demos from the release tarballs, added some |
| others. |
