    *   Changing signature of `MakeIterator` to enable propagating error status.
    *   KL divergence for two Dirichlet distributions.
    *   More consistent GcsFileSystem behavior for certain reads past EOF.
    *   Update benchmark for tf.scan to match ranges across eager and graph
        modes.
    *   Fixed bug in `tf.reduce_prod gradient` for complex dtypes.
