+Mesa 19.2.1 Release Notes / 2019-10-09
+======================================
+
+Mesa 19.2.1 is a bug fix release which fixes bugs found since the 19.2.0
+release.
+
+Mesa 19.2.1 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.
+Compatibility contexts may report a lower version depending on each
+driver.
+
+Mesa 19.2.1 implements the Vulkan 1.1 API, but the version reported by
+the apiVersion property of the VkPhysicalDeviceProperties struct depends
+on the particular driver being used.
