Mesa 10.6.0 Release Notes / June 14, 2015
=========================================

Mesa 10.6.0 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 10.6.1.

Mesa 10.6.0 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.
