Mesa 11.0.0 Release Notes / September 12, 2015
==============================================

Mesa 11.0.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 11.0.1.

Mesa 11.0.0 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.
