    *   Extended `tf.config.experimental.enable_tensor_float_32_execution` to
        control Tensor-Float-32 evaluation in RNNs.
    *   Added a 'experimental_payloads' field to tf.errors.OpError and its
        subclasses to support more detailed error reporting. This is inspired
        from Abseil Status payloads:
