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 infrastructure.

+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). + PLEASE 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 Superseded by the ARB versions.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.
