Users can now choose to subscribe to a 'New content alert' email. An admin user would configure this to run daily or weekly at a given time of the day. When run, users who have subscribed will get an automatic email notification if new content has been uploaded that they have permission to see. This is a great way for users to stay up to date.

Admin users can configure the frequency via:

Admin > System > "New Content Notification Settings"

Admin users can also decide of all new users should have this set by default. Finally, users themselves can opt in/out via their profile page.
