What's new from TensorFlow v1.6 forwards?

In 2015, Google made TensorFlow open source, including all of its reference implementation. All of the source code was made available on GitHub under the Apache 2.0 license. Since then, TensorFlow has been widely adopted in academia and industrial research, and the most stable version, 1.6, has recently been released with a unified API.

It is important to note that the APIs in TensorFlow 1.6 (and higher) are not all backward compatible for pre v1.5 code. This means that some programs that worked on pre v1.5 will not necessarily work on TensorFlow 1.6.

Now let us see the new and exciting features that TensorFlow v1.6 has.
