Traction TeamPage Release 4.0 first shipped in June 2008 with support for moderation, page name history and management and user profile pages. Moderation allows for typical publish and reject operations for comments, but also makes it possible for authorized users to work in and fully experience the Draft version of the wiki or flip to the Published version to compare. Page Name management is the first to introduce page name history, the ability to alias page names across wiki projects, and the concept of a global page name space from which names can be applied to any wiki project space.
