*   Bug Fixes:
    *   Fix bug where partitioned integer variables got their wrong shapes.

    *   Fix correctness bug in CPU and GPU implementations of Adadelta.
    *   Fix a bug in `import_meta_graph`'s handling of partitioned variables
        when importing into a scope. WARNING: This may break loading checkpoints
        of graphs with partitioned variables saved after using

    //   * task:0 processes main function `VariableAddFunctionWithGraphError`
    //     and places the 'read0_maybe_with_graph_error' op on task:2
    //   * task:0 partitions the main function with a subgraph containing
