Mesa 11.2.2 Release Notes / May 9, 2016
=======================================

Mesa 11.2.2 is a bug fix release which fixes bugs found since the 11.2.1
release.

Mesa 11.2.2 implements the OpenGL 4.1 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
4.1. OpenGL 4.1 is **only** available if requested at context creation
because compatibility contexts are not supported.
