Gotcha... thanks DeepSpace! Ideally there would be a "Beta" page where they are posted off the main "Anystream forum".If you subscribe to the AS forum, then you will get a notification if a new post gets created, like this one. But then you will also get notifications for other threads. Maybe they can create an update subforum, where only updates for all programs get postet, so if you are not interested in the forum itself or in every post, then you can subscribe to this one.
AS itself gives you a notification for new updates, but not for all (betas).
