Mesa 9.2.1 Release Notes / (October 4, 2013)
============================================

Mesa 9.2.1 is a bug fix release which fixes bugs found since the 9.2
release.

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.
