Mesa 17.3.1 Release Notes / December 21, 2017
=============================================

Mesa 17.3.1 is a bug fix release which fixes bugs found since the 17.3.0
release.

Mesa 17.3.1 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
because compatibility contexts are not supported.
