*   Large cleanup to add second order gradient for ops with C++ gradients and
    improve existing gradients such that most ops can now be differentiated
    multiple times.
*   Added a solver for ordinary differential equations,
    `tf.contrib.integrate.odeint`.
*   New contrib module for tensors with named axes, `tf.contrib.labeled_tensor`.
*   Visualization of embeddings in TensorBoard.
