Some sort of update status for the user.
Idea from Drupal - "update status"
Small script with info to user about new version.
Include a usage reporting feature. We only have download stats.
It would be nice to have some more stats about our user base
- anonymous reporting
- how many installations we have on each version
- how many users on each installation
Pine have had a simple one for over 10 years (on first run - send report e-mail)
