430 :     occurs off the widget, no change is registered. Event streams for
431 :     general buttons now terminate with either button up or exit, the latter
432 :     indicating the mouse has left the widget. Buttons and toggles also now
433 :     provide active/inactive state.

438 :    
439 :     GLOBAL CHANGES:
440 :     - eXene is now based on CML-0.9.4; this very required minor changes to
441 :     eXene (now using 0.9.6).
442 :    
443 :     - ported to SML/NJ 0.71. Most changes were a result of the Array structure
444 :     not being open by default, and by Array.sub no longer being an infix operator.

461 :    
462 :     - changed remove function for hash tables to return the removed item. This
463 :     affected the hash tables defined in util/{hash-util.sml,hash-xid.sml},
464 :     window/hash-window.sml and user/eXene-base.sml.
465 :    
466 :     - added window-tree locking mechanism to the window registry.
467 :
