# Mesa 10.2 Release Notes / June 6, 2014

Mesa 10.2 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 10.2.1.

Mesa 10.2 implements the OpenGL 3.3 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 3.3. OpenGL 3.3 is only available if requested at context creation because compatibility contexts are not supported.

- GL_INTEL_performance_query on i965/gen5+

## Bug fixes

TBD.

## Changes

- Renamed --with-llvm-shared-libs to --enable-llvm-shared-libs

The option is used to control how mesa is linked against LLVM, and now defaults to enabled (shared linking).

- Split libxatracker.so into a standalone library which can be used with any gallium driver.

Previously the library was linked statically against vmware's virtual gpu driver(svga), whereas now it loads a shared pipe_*.so driver. Provide the following options during configure, if you would like support for svga driver --enable-xa --with-gallium-drivers=svga

Note: The files are installed in $(libdir)/gallium-pipe/ and the interface between them and libxatracker.so is not stable.

- The environment variable GALLIUM_MSAA that forced a multisample GLX visual was removed.
