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

464 :     -----------------------------
465 :    
466 :     GLOBAL CHANGES:

468 :     eXene (now using 0.9.6).
469 :
