+Mesa 19.0.8 Release Notes / June 26, 2019
+=========================================
+
+Mesa 19.0.8 is an emergency bug fix release which fixes a critical bug
+found in the 19.0.7 release.
+
+Mesa 19.0.8 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.
