# Mesa 10.2.2 Release Notes / June 24, 2014

Mesa 10.2.2 is a bug fix release which fixes bugs found since the 10.2.1 release.

Mesa 10.2.2 implements the OpenGL 3.3 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 3.3. OpenGL 3.3 is only available if requested at context creation because compatibility contexts are not supported.
