Mesa 18.1.0 Release Notes / TBD

Mesa 18.1.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 18.1.1.

Mesa 18.1.0 implements the OpenGL 4.5 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 4.5. OpenGL 4.5 is only available if requested at context creation. Compatibility contexts may report a lower version depending on each driver.
