+Mesa 25.1.3 Release Notes / 2025-06-07
+======================================
+
+Mesa 25.1.3 is a bug fix release which fixes bugs found since the 25.1.2 release.
+
+Mesa 25.1.3 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 **only** available if requested at context creation.
+Compatibility contexts may report a lower version depending on each driver.
+
+Mesa 25.1.3 implements the Vulkan 1.4 API, but the version reported by
+the apiVersion property of the VkPhysicalDeviceProperties struct
+depends on the particular driver being used.
