+<h1>Mesa 19.2.1 Release Notes / 2019-10-09</h1>
+
+<p>
+ Mesa 19.2.1 is a bug fix release which fixes bugs found since the 19.2.0 release.
+</p>
+<p>
+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 <strong>only</strong> available if requested at context creation.
+Compatibility contexts may report a lower version depending on each driver.
+</p>
+<p>
+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.
+</p>
