    *   AutoGraph error messages now exclude frames corresponding to APIs
        internal to AutoGraph.
    *   Improve shape inference for `tf.function` input arguments to unlock more
        Grappler optimizations in TensorFlow 2.x.
    *   Improve automatic control dependency management of resources by allowing
        resource reads to occur in parallel and synchronizing only on writes.
