## Bug Fixes and Other Changes

*   `tf.nn.rnn_cell.DropoutWrapper` is now more careful about dropping out LSTM
    states. Specifically, it no longer ever drops the `c` (memory) state of an
    `LSTMStateTuple`. The new behavior leads to proper dropout behavior for
    LSTMs and stacked LSTMs. This bug fix follows recommendations from published
