Along with 1.9, we are also releasing major updates to the PyTorch libraries, which you can read about in this blog post. 
We’d like to thank the community for their support and work on this latest release. We’d especially like to thank Quansight and Microsoft for their contributions.
Features in PyTorch releases are classified as Stable, Beta, and Prototype. You can learn more about the definitions in this blog post.
