# Mesa 10.3 Release Notes / September 19, 2014

Mesa 10.3 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 10.3.1.

Mesa 10.3 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.

## Changes

- Removed support for the GL_ATI_envmap_bumpmap extension
- The hacky --enable-32/64-bit is no longer available in configure. To build 32/64 bit mesa refer to the default method recommended by your distribution
The environment variable GALLIUM_MSAA that forced a multisample GLX visual was removed.
