Mesa, also called Mesa3D and the Mesa 3D Graphics Library, is an open source software implementation of OpenGL, Vulkan, and other graphics API specifications. Mesa translates these specifications into manufacturer specific graphics hardware drivers.
Mesa 19.3.0 is a new development version. People who are concerned about stability and reliability should stick to the previous version or wait for Mesa 19.3.1.
Mesa 19.3.0 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 used. Some drivers do not support all the features required by OpenGL 4.6. OpenGL 4.6 is only available on request when creating a context. Compatibility contexts may report a lower version depending on each driver.
Mesa 19.3.0 implements the Vulkan 1.1 API, but the version reported by the apiVersion property of the VkPhysicalDeviceProperties structure depends on the particular driver used.
