I'm forward dating this, but as you read this the bits should start becoming available. Congrats to the team on a focused release < 3 years since the last release.
The various SKUs and supplimental bits such as the Feature Pack are going to be coming available over the next few weeks.
Once all the links go live I'll update this post with the links.
