-Drag and Drop Release Notes
-
-0.12.0
-
-   * The logic to determine if a drag should be initiated has been isolated
-     to the clickValidator method.  This method can be overridden to provide
-     custom valdiation logic.  For example, it is possible to specify hotspots
-     of any dimension or shape.  The provided example shows how to make only
-     a circular region in the middle of the element initiate a drag.
-
-   * Added a new drag and drop event: onInvalidDrop.  This is executed when
-     the dragged element in dropped in a location without a target.  Previously
-     this condition could only detected by implementing handlers for three 
-     other events.
-
-   * Now accepts an element reference in lieu of an id.  Ids will
-     be generated if the element does not have one.
-
-   * Fixed horizontal autoscroll when scrollTop is zero.
-
-   * Added hasOuterHandles property to bypass the isOverTarget check in the
-     mousedown validation routine.  Fixes setOuterHandleElId.
-
-0.11.4
-
-   * YAHOO.util.DragDropMgr.swapNode now handles adjacent nodes properly
-   
-   * Fixed missing variable declarations
-
-0.11.3
- 
-   * Fixed a JavaScript error that would be generated when trying to implement
-     DDProxy using the default settings and a tiny element.
-
-   * Fixed an error that resulted when constraints were applied to DragDrop 
-     instances.
-
-0.11.2
-
-   * Drag and drop will no longer interfere with selecting text on elements
-     that are not involved in drag and drop.
-
-   * The shared drag and drop proxy element now resizes correctly when autoResize
-     is enabled.
-
-0.11.1
-
-   * Fixes an issue where the setXY cache could get out of sync if the element's
-     offsetParent is changed during onDragDrop.
-
-0.11.0
-
-   * The Dom.util.setXY calculation for the initial placement of the dragged
-     element is cached during the drag, enhancing the drag performance.
-
-   * DDProxy no longer enforces having a single proxy element for all instances.
-     dragElId can be set in the config object in the constructor.  If the
-     element already exists it will use that element, otherwise a new one will
-     be created with that id.
-
-   * DDProxy->borderWidth has been removed. The value is calculated on the fly
-     instead.
-
-   * Added DragDrop->clearTicks and DragDrop->clearConstraints
-
-   * All drag and drop constructors now have an additional, optional parameter
-     call "config".  It is an object that can contain properties for a
-     number of configuration settings.
-
-   * Drag and drop will not be disabled for elements that cannot have their
-     location determined.
-
-   * isLegalTarget won't return dd objects that are not targetable.
-
-   * Added DragDrop->removeFromGroup.
-
-   * Constraints are now applied properly when determining which drag and drop
-     events should fire.
-
-
-0.10.0
-
-   * Improved the performance when in intersect mode
-
-   * It was possible for the drag and drop initialization to be skipped
-     for very slow loading pages.  This was fixed.
-
-   * New methods to exclude regions within your drag and drop element: 
-     addInvalidHandleId(), addInvalidHandleClass()
-
-   * Added an onAvailable handler that is executed after the initial state is set.
-
-   * Drag and drop is more forgiving when the implementer attempts to create the
-     instance prior to the element being in the document, but after the window
-     load event has fired.
