There’s a feature suggestion, discussing to display/edit the full queue from within Plexamp. You can vote for this feature there. Though, that’s no guarantee it’ll be implemented.

You should be able to configure notifications which can include technical stuff about your own media but also announcements from Plex.

There’s an option to sign up for Plex‘s newsletter / official communications in your account preferences.

If you’re looking for updates on new releases, there’s a release notes thread for Plexamp in this forum (and an entire category for the server and other apps). You can follow those threads to be informed if a new update is posted.
