Plone is Python's leading content management system, and this is a major milestone for open source content management systems. Recent converts to Plone include Novell, Akamai... and the CIA. Major new features in this release is pervasive versioning, automatic locking, links that never break and ajax-powered inline editing. The list of features is a good start if you're wondering what it can do."
