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

447 :     eXene-0.3 (released 12/03/91)
448 :     -----------------------------
449 :    
450 :     GLOBAL CHANGES:
451 :     - eXene is now based on CML-0.9.4; this very required minor changes to
452 :     eXene (now using 0.9.6).
453 :    
454 :     - ported to SML/NJ 0.71. Most changes were a result of the Array structure
455 :     not being open by default, and by Array.sub no longer being an infix operator.

457 :    
458 :     LIBRARY CHANGES

460 :     by SML/NJ 0.70.
461 :

466 :     semantics of the protocol.

472 :
