<h1>Mesa 12.0.6 Release Notes / January 23, 2016</h1>

<p>
Mesa 12.0.6 is a bug fix release which fixes bugs found since the 12.0.5 release.
</p>
<p>
Mesa 12.0.6 implements the OpenGL 4.3 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 4.3.  OpenGL
4.3 is <strong>only</strong> available if requested at context creation
because compatibility contexts are not supported.
</p>
