Coincidentally I recently added a "history" feature to Chandler's  
built in repository-browsing servlet so a developer can examine the  
changes an item's values have gone through over time.  To see it in  
action, fire up Chandler, click on the item you are interested in  
(either in the List view or Calendar view) then hit the F4 key.  This  
will start Chandler's internal webserver and launch your default web  
browser to a page that gives details on the selected item.  Near the  
top of that page you will find a link named "Show history" which will  
display a table of changes and the repository version number at which  
those changes took place.

This history information is computed from the module chandler/util/ 
inspector.py which is based on some of Andi's repository code.
