# Mesa 7.7 Release Notes / 21 December 2009

Mesa 7.7 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 7.7.1.

Mesa 7.7 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.

## New features

- VMware "SVGA" Gallium driver. This is a Gallium3D driver which targets the VMware virtual graphics device. It allows Linux OpenGL guest applications to utilize the 3D graphics hardware of the host operating system.
- GL_ARB_draw_elements_base_vertex (supported in Intel i965 and software drivers)
- GL_ARB_depth_clamp (supported in Intel i965 DRI and software drivers)
- GL_NV_depth_clamp (supported in Intel i965 DRI and software drivers)
- GL_ARB_provoking_vertex (same as GL_EXT_provoking_vertex)
- Wavefront .obj file loader/viewer demo (progs/demos/objviewer)

## Bug fixes

- Many assorted i965 driver fixes.
- Many r300-gallium driver fixes; this driver is now considered unstable-quality instead of experimental-quality.

## Changes

- New Mesa texture/surface format infrastructure
- Removed some unused Mesa device driver hooks
