# The Mesa 3D Graphics Library

# Mesa 9.2 Release Notes / (date TBD)

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.
