Remove or hide archived changelog entries from the user notification feed

When we unpublish a changelog entry it becomes archived, hidden from our changelog, our widget announcements, our RSS feed and our sitemap. One place still shows it. Users who were notified when the entry published keep that notification in their feed, with its original title. Clicking it opens a page that no longer exists. Curiously, deleting an entry behaves better here: the notification loses its title instead of pointing at a dead page. Archiving, leaves the more confusing result. Possible solutions Hide it, the notification disappears once the entry is archived. Cleanest feed, but it removes something that genuinely happened to that user. Keep it, drop the link, the notification stays as a record, but is no longer clickable and reads as no longer available. Leave it as it is, the user was told about the entry at the time, so the notification is an accurate record of that moment.
