1Mesa 9.2 Release Notes / (August 27, 2013) 2========================================== 3 4Mesa 9.2 is a new development release. People who are concerned with 5stability and reliability should stick with a previous release or wait 6for Mesa 9.2.1. 7 8Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by 9glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / 10glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being 11used. Some drivers don't support all the features required in OpenGL 123.1. OpenGL 3.1 is **only** available if requested at context creation 13because GL_ARB_compatibility is not supported. 14 15MD5 checksums 16------------- 17 18:: 19 20 4f93c6475ec656fc1f7b93aeffc9b6c4 MesaLib-9.2.0.tar.gz 21 4185b6aae890bc62a964f4b24cc1aca8 MesaLib-9.2.0.tar.bz2 22 3bc5339bc98b9c37777ffd14e3a8eca4 MesaLib-9.2.0.zip 23 24New features 25------------ 26 27Note: some of the new features are only available with certain drivers. 28 29- GL_ARB_shading_language_420pack in all drivers that support GLSL 30 1.30. 31- GL_ARB_texture_buffer_range 32- GL_ARB_texture_multisample 33- GL_ARB_texture_storage_multisample 34- GL_ARB_texture_query_lod 35- GL_ARB_texture_storage on radeon, r200, and nouveau 36- GL_EXT_discard_framebuffer in all OpenGL ES (all versions) drivers 37- GL_EXT_framebuffer_multisample_blit_scaled on i965 38- Added new freedreno gallium driver 39- OSMesa interface for gallium llvmpipe/softpipe drivers 40- Gallium Heads-Up Display (HUD) feature for performance monitoring 41- Added support for UVD (2.2 and 3.0) video decoding on r600g and 42 radeonsi through VDPAU (requires Kernel 3.10 or later) 43 44Bug fixes 45--------- 46 47Attempts have been made to **not** include bugs fixed in previous 9.1 48releases or bugs that were regressions during 9.2 development.
