# The Mesa 3D Graphics Library

# Mesa 10.5.0 Release Notes / March 06, 2015

Mesa 10.5.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 10.5.1.

Mesa 10.5.0 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.
