Mesa 7.11 Release Notes / July 31, 2011

+ +

+Mesa 7.11 is a new development release. +People who are concerned with stability and reliability should stick +with a previous release or wait for Mesa 7.11.1. +

+Mesa 7.11 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 Compiling/Installing page for prerequisites +for DRI hardware acceleration. +

Changes

The Windows MSVC project files have been removed. +They haven't been maintained in quite a while. +Building with SCons is an alternative. +
Removed GL_SGI_texture_color_table support from swrast driver - the only +driver that implemented it. +
