Mesa 17.0.2 Release Notes / March 20, 2017
==========================================

Mesa 17.0.2 is a bug fix release which fixes bugs found since the 17.0.1
release.

Mesa 17.0.2 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.
