* Support gradient `allreduce` in `float16`. See this [example](https://github.com/tensorflow/models/blob/master/official/staging/training/grad_utils.py) usage.
* Experimental support of [all reduce gradient packing](https://www.tensorflow.org/api_docs/python/tf/distribute/experimental/CollectiveHints) to allow overlapping gradient aggregation with backward path computation.
* Deprecated `experimental_run_v2` method for distribution strategies and renamed the method `run` as it is no longer experimental.
* Add CompositeTensor support for DistributedIterators. This should help prevent unnecessary function retracing and memory leaks.
*`tf.keras`:
*`Model.fit` major improvements:
* You can now use custom training logic with `Model.fit` by overriding `Model.train_step`.
