General overview
TensorFlow is an open source software library for numerical computation using data flow graphs that enables machine learning practitioners to do more data-intensive computing. It provides some robust implementations of widely used deep learning algorithms. Nodes in the flow graph represent mathematical operations. On the other hand, the edges represent multidimensional tensors that ensure communication between edges and nodes. TensorFlow offers you a very flexible architecture that enables you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.
What's new with TensorFlow 1.x?
The APIs in TensorFlow 1.0 have changed in ways that are not all backward-compatible. That is, TensorFlow programs that worked on TensorFlow 0.x won't necessarily work on TensorFlow 1.x. These API changes have been made to ensure an internally-consistent API. In other words, Google does not have any plans to make TensorFlow backwards-breaking changes...
