373 :    
374 :     - The function mkSBLayout has been moved to its own structure ScrollLayout

379 :     - mkColorRect has been added to implement simple colored rectangular regions.
380 :    
381 :     - A background_t widget has been added to implement backgrounds for widgets

423 :     - Toggle and button protocol has changed. Command and toggle buttons
424 :     register a change on button up, not on button down. If button up
425 :     occurs off the widget, no change is registered. Event streams for
426 :     general buttons now terminate with either button up or exit, the latter
427 :     indicating the mouse has left the widget. Buttons and toggles also now
428 :     provide active/inactive state.

433 :    
434 :     GLOBAL CHANGES:
435 :     - eXene is now based on CML-0.9.4; this very required minor changes to
436 :     eXene (now using 0.9.6).
437 :

456 :    
457 :     - changed remove function for hash tables to return the removed item. This

459 :     window/hash-window.sml and user/eXene-base.sml.
460 :    
461 :     - added window-tree locking mechanism to the window registry.
