# The Mesa 3D Graphics Library

# Mesa 9.1.1 Release Notes / March 19th, 2013

Mesa 9.1.1 is a bug fix release which fixes bugs found since the 9.1 release.

Mesa 9.1 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.
