Right now, announcements about new features only live on the community site, so users that don't check it regularly discover changes by running into them.
Request: surface new feature announcements inside Hudu itself.
A noticeable in-app indicator (toolbar icon or dashboard tile) when there are unread announcements. Subtle animation is what catches the eye. Clicking opens a list of recent changes.
An optional guided tour launched from that indicator, with dismiss and "remind me later" options so it doesn't interrupt work.
