+Mesa 18.0.5 Release Notes / June 3, 2018
+========================================
+
+Mesa 18.0.5 is a bug fix release which fixes bugs found since the 18.0.4
+release.
+
+Mesa 18.0.5 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.
