* Remove integer types from `tf.nn.softplus` and `tf.nn.softsign` OpDefs.
This is a bugfix; these ops were never meant to support integers.
* Allow subslicing Tensors with a single dimension.
* Add option to calculate string length in Unicode characters
* Add option to calculate string length in Unicode characters.
* Add functionality to SubSlice a tensor.
* Add searchsorted (ie lower/upper_bound) op.
* Add model explainability to Boosted Trees.
* Support negative positions for tf.substr
* Support negative positions for tf.substr.
* There was previously a bug in the bijector_impl where the
_reduce_jacobian_det_over_event does not handle scalar ILDJ
implementations properly.
* In tf eager execution, allow re-entering a GradientTape context
* In tf eager execution, allow re-entering a GradientTape context.
* Add tf_api_version flag. If --define=tf_api_version=2 flag is passed in,
then bazel will build TensorFlow API version 2.0. Note that TensorFlow
2.0 is under active development and has no guarantees at this point.
* Add additional compression options to TfRecordWriter
* Add additional compression options to TfRecordWriter.
* Performance improvements for regex full match operations.
* Replace tf.GraphKeys.VARIABLES with `tf.GraphKeys.GLOBAL_VARIABLES`
* Replace tf.GraphKeys.VARIABLES with `tf.GraphKeys.GLOBAL_VARIABLES`.
* Remove unused dynamic learning rate support.

## Major Features and Improvements
* Nvidia GPU:
* Prebuilt binaries are now (as of TensorFlow 1.11) built against cuDNN 7.2 and TensorRT 4. See updated install guides: [Installing TensorFlow on Ubuntu](https://www.tensorflow.org/install/install_linux#tensorflow_gpu_support)
* Google Cloud TPU:
* Experimental tf.data integration for Keras on Google Cloud TPUs.
* Experimental / preview support for eager execution on Google Cloud TPUs.
* DistributionStrategy:
* Add multi-GPU DistributionStrategy support in tf.keras. Users can now use `fit`, `evaluate` and `predict` to distribute their model on multiple GPUs.
* Add multi-worker DistributionStrategy and standalone client support in Estimator. See [README] (https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/distribute) for more details.
* Add C, C++, and Python functions for querying kernels
