```Python
async def do_something():
    try:
        yield something
    finally:
        some_cleanup()
```

...that way the `finally` block is run regardless of any exception that might happen.

*   Higher level functionality in contrib. {layers,losses,metrics,learn}
*   More features to Tensorboard
*   Improved support for string embedding and sparse features
*   The RNN api is finally "official" (see, e.g., `tf.nn.dynamic_rnn`,
    `tf.nn.rnn`, and the classes in `tf.nn.rnn_cell`).
*   TensorBoard now has an Audio Dashboard, with associated audio summaries.
