Feature request: filter Pre-releases from notifications (Watch -> Custom -> Releases)

It would be great if you could filter Pre-releases from notifications to avoid spamming. I guess most people are mainly interested about being notified about an actual release and don’t care that much about nightly versions (pre-releases).

Therefore there should be an option where you can specify that.
Watch → Custom → Releases → All | Pre-releases | Releases (as checkboxes)

This is status quo:
