Also see the ’ Preview of 2020.1 features ’ post for links to feature documentation available at this time.
Please remember to back up your projects before opening them in an alpha build!
Thank you! 
Alpha 9 didn’t have it either:
Neither had the previous versions for that matter: https://unity3d.com/unity/alpha/2020.1.0a3 
When will it be in the Hub? It not at the time I write this; I quit and restarted the Hub to make sure of that. @AbrahamDUnity
It’s now also on the hub
I’m getting an error message on creating a new project. The project is a 2D project and this message pops up when I open the Package Manager window. It happened several times.

Another message. This one I get when Unity editor is in the background and I make it go back to the foreground. For example, right now, I’m writing this, Firefox is in the foreground and Unity is just behind it. When I’m finished writing this, I’ll click on Unity so that it comes back to the foreground and the error message will pop up in the console. This happens each time.

One day @ , I promise.
Why do you post this in the announcement thread? 
I believe it makes more sense to create an own/separate thread for each individual issue, just like Unity asks us to do:
Nobody reads them.
That said, if a mod wants to create a new thread and regroup the error messages I’ve posted here, please, help yourselves.
Removing the 2D Sprite Shape package fixes the problem; removing and reinstalling it doesn’t.
flinches and backs off
LOL How courageous! LOL
