Mesa 9.1.2 Release Notes / April 30th, 2013

18
 
19

20
Mesa 9.1.2 is a bug fix release which fixes bugs found since the 9.1.1 release.
21

22

23
Mesa 9.1 implements the OpenGL 3.1 API, but the version reported by
24
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
25
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
26
Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
27
3.1 is only available if requested at context creation
28
because GL_ARB_compatibility is not supported.
