1Mesa 17.2.7 Release Notes / December 14, 2017
2=============================================
3
4Mesa 17.2.7 is a bug fix release which fixes bugs found since the 17.2.6
5release.
6
7Mesa 17.2.7 implements the OpenGL 4.5 API, but the version reported by
8glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
9glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
10used. Some drivers don't support all the features required in OpenGL
114.5. OpenGL 4.5 is **only** available if requested at context creation
12because compatibility contexts are not supported.
