@kkondaka @dlvenable @graytaylor0 - Please add me to the working doc for the blog when you have a chance. This way I can follow the progress and ensure it publishes on time.

@pajuric , I will be the author for this blog post and will attempt to get a PR submitted as soon as possible.

We are going to release on Aug 28, or the 29th, at the latest. I'd like to have the blog available at release if possible, but I also see it is somewhat short turn-around.

@pajuric , I created #3228 with the initial blog post.
