Mesa 10.4 Release Notes / December 14, 2014
===========================================

Mesa 10.4 is a new development release. People who are concerned with
stability and reliability should stick with a previous release or wait
for Mesa 10.4.1.

Mesa 10.4 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.

Changes
-------

-  The environment variable GALLIUM_MSAA that forced a multisample GLX
   visual was removed.
