It looks like API have been change a few examples of the update.
From "C4_TicketView::setLastAction($view_id,null);" to "View_Ticket::setLastAction($view_id,null);" It looks like all the DAO / View class structure. This will make following the code much easier. The new breakdown seems to be DAO_XXX for database access, Model_XXX for the data structure. SearchFields_XXX sets up how to search for that data and finally View_XXX how to view that data as a list. It is clear that is were Cerberus is heading all data will be a view. That makes a lot of since and having the API more consistent will be an improvement for those of us working on the code. At this point it looks like the API changes are about half done. That means the Cerberus 5 tree is really unstable right now. Hopefully in a week or two the Database changes and API clean up will be finished and Cerberus 5 is more stable at that point.
Thanks
