WOW Insider clued me in to this site that tracks addon updates. You can subscribe to the database through Twitter, Google Reader, RSS feeds, etc. so it is easy to keep track of what has changed. If you don't want to bother with that, you can bookmark the site and use the search box at the top of the page to find out if your favorite addons have been changed. It appears you can register with the site and then customize and save the view you get when you visit but I haven't tested this. Thank you, Fin. This will be very useful.
