CANS 2.0 is now available as a SVN download at https://source.sakaiproject.org/contrib/cans/cans_server/trunk/. In addition, you may checkout our progress on our latest Sakai front-end tool for CANS at https://source.sakaiproject.org/contrib/cans/cans_AM/trunk/. This tool, known as the Activity Monitor tool, allows Sakai's site owners to setup notification preferences for Sakai sites and view notifications using our new Flex-based activity notifiers.

Enjoy.
