Mesa 9.1.5 Release Notes / July 17, 2013
========================================

Mesa 9.1.5 is a bug fix release which fixes bugs found since the 9.1.4
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.
