*   Add support for 3d convolutions and pooling.
*   Update gRPC release to 0.14.
*   Eigen version upgrade.
*   Switch to eigen thread pool
*   `tf.nn.moments()` now accepts a `shift` argument. Shifting by a good
    estimate of the mean improves numerical stability. Also changes the behavior
    of the `shift` argument to `tf.nn.sufficient_statistics()`.
*   Performance improvements
*   Many bugfixes

the concatenation, will use the values of the captured tensors available to it.
Therefore, typical uses of captured tensors should involve values which remain
unchanged across session.run calls. Inference is a good example of this.

SparseTensor is not supported. The return value of the decorated function
must be a Tensor or a list/tuple of Tensors.
