Mesa 10.5.1 Release Notes / March 13, 2015
==========================================

Mesa 10.5.1 is a bug fix release which fixes bugs found since the 10.5.0
release.

Mesa 10.5.1 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.
