    - node.module:
    
       + Changed node_form() to use good ol' tables instead of div/CSS-tags.
    
       + Revised the "revision API": I think we have both an easy and powerful
         API now that should make everyone happy.
    
       + Improved the usability of the rollback functionality a bit.
    
       + Removed the "view node" link from the "node overview" page in the
         admin section and added a "delete node" link instead.
    
       + Added a few missing translations; there might be missing more
         translations though.
    
    - book.module:
    
       + Made the book module use the "revision API" instead of having it poke
         and use the innards and underlying details of the revision system.
    
    - queue.module:
    
       + Made the queue module use the improved revision number.
    
    - module.inc:
       + Applied Moshe's patch: added more arguments to module_invoke()
    
    - mail-to-sql.pl:
       + Added support for more header fields and for folded fields
    
    Notes:
    
    - no database updates required
