# Mesa 13.0.1 Release Notes / November 14, 2016

Mesa 13.0.1 is a bug fix release which fixes bugs found since the 13.0.0 release.

Mesa 13.0.1 implements the OpenGL 4.4 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 4.4. OpenGL 4.4 is only available if requested at context creation because compatibility contexts are not supported.
