Mesa 9.2 Release Notes / (August 27, 2013) ========================================== Mesa 9.2 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 9.2.1. Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 3.1. OpenGL 3.1 is **only** available if requested at context creation because GL_ARB_compatibility is not supported.

Removed GL_EXT_clip_volume_hint because no driver had enabled it since 2007. - Removed GL_MESA_resize_buffers because it was only really implemented by the (unsupported) GDI driver. - GL_EXT_separate_shader_objects has been removed from all Gallium drivers, because it disallows a critical GLSL shader optimization. GL_ARB_separate_shader_objects doesn't have this issue. - i965 Gen6+ requires Kernel 3.6 or later. (92d2f5a)
