Apple released a collection of updates on September 28. You can read more about them here. The updates focus on group usability--such as automated e-mails when comments are made. Those of us who have been using iWork.com have been handling these notification issues manually, so this is a great time-saver.There will be an iWork Extra in the next few days with more details. Check back here. And if you haven't already, sign up for our newsletter. The Extras show up there.
