+<h1>Mesa 20.1.5 Release Notes / 2020-08-05</h1>
+ Mesa 20.1.5 is a bug fix release which fixes bugs found since the 20.1.4 release.
+Mesa 20.1.5 implements the OpenGL 4.6 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 4.6. OpenGL
+4.6 is <strong>only</strong> available if requested at context creation.
+Compatibility contexts may report a lower version depending on each driver.
+Mesa 20.1.5 implements the Vulkan 1.2 API, but the version reported by
+the apiVersion property of the VkPhysicalDeviceProperties struct
+depends on the particular driver being used.
