10<h1>Mesa 9.0 Release Notes / date TBD</h1>
11
12<p>
13Mesa 9.0 is a new development release.
14People who are concerned with stability and reliability should stick
15with a previous release or wait for Mesa 9.0.1.
16</p>
17<p>
18Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by
19glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
20glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
21Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
223.1 is <strong>only</strong> available if requested at context creation
23because GL_ARB_compatibility is not supported.
