h1>Mesa 9.1.3 Release Notes
/ May 21st,
2013<
/h1>
Mesa 9.1.3 is a bug fix release which fixes bugs found since the 9.1.1 release.
Mesa 9.1 implements the OpenGL 3.1 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 3.1. OpenGL
3.1 is <strong>only</strong> available if requested at context creation
because GL_ARB_compatibility is not supported.
