14Mesa 7.5 is a new development release.
Brian Paulce01de52009-04-07 18:23:21 -0600[diff] [blame]15People who are concerned with stability and reliability should stick
Brian Paule4e7ecc2009-04-30 17:17:31 -0600[diff] [blame]16with the 7.4.x branch or wait for Mesa 7.5.1.

19The main new feature of Mesa 7.5 is the

24Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by
25glGetString(GL_VERSION) depends on the particular driver being used.
26Some drivers don't support all the features required in OpenGL 2.1.

33Note that the Mesa project is no longer using odd/even version numbers
34to indicate development/stable releases.
35The so-called development releases have been fairly stable.
36If 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.

Brian Paulce01de52009-04-07 18:23:21 -0600[diff] [blame]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
Kai Wasserbächccd4d432011-11-29 18:17:47 +0100[diff] [blame]64 <li>Cell - IBM/Sony/Toshiba Cell processor driver

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.
