-* Initial release
+Container Release Notes
+
+*** version 2.3.0 ***
+
+Fixed the following bugs:
+-------------------------
+
++ Improved creation of the <iframe> element used to monitor changes to the 
+  browser's font size so that:
+  
+    - Safari's status bar no longer displays a "Loading..." message after the 
+      page has loaded.
+  
+    - Firefox no longer reports duplicate cookie information.
+    
+    - The browser scrollbars no longer flash on and off in Firefox.
+
++ It is now possible to set the "button" configuration property of a 
+  YAHOO.widget.Dialog instance after it has be rendered.
+
++ Form elements appended to a YAHOO.widget.Dialog instance via the "setBody"
+  method are now automatically registered using the "registerForm" method.
+
++ The "focusFirst" method of YAHOO.widget.Dialog will no longer result in a 
+  JavaScript error in IE if the first element in the Dialog instance's form
+  is a radio button.
+
++ YAHOO.widget.Panel instances whose "draggable" property is set to "true" and
+  "width" property is set to "auto" are now able to be dragged in IE 6 (Quirks
+  and Strict Mode) and IE 7 Quirks Mode.
+
++ Updated focus methods of YAHOO.widget.Dialog to prevent JavaScript errors 
+  that result from trying to set focus to elements that hidden or disabled.
+
++ Pressing the enter key will no longer result in a YAHOO.widget.Dialog 
+  instance's "validate" method being called twice.
+
++ Pressing the enter key while focused on a form field inside a Dialog will no
+  longer trigger the "click" event handler defined by the Dialog's default 
+  button in IE and Firefox.
+
++ Pressing the enter key when focused on a form field inside a 
+  YAHOO.widget.Dialog instance with no buttons created via its "buttons" 
+  configuration property will no longer result in a JavaScript error.
+
++ Aqua scrollbars will no longer bleed through Container widgets in Firefox
+  for Mac OS X.
+
++ The "width" and "height" configuration properties of YAHOO.widget.Overlay
+  now supersede the "fixedcenter" and "context" configuration properties to 
+  ensure correct positioning of Overlay instances using the "fixedcenter" 
+  and "context" configuration properties.
+
++ Calling the "destroy" method on a YAHOO.widget.Overlay instance no longer 
+  results in a JavaScript error on the subsequent focus of another 
+  Overlay instance.
+
++ YAHOO.widget.Tooltip instances without a value specified for the "width" 
+  configuration property will be rendered at a width equal to the offsetWidth
+  of their root <DIV/> element to prevent their width from being clipped or 
+  constrained by their parent HTML element.
+
+
+Changes:
+--------
+
++ Rendering of YAHOO.widget.Tooltip instances is now deferred using the 
+  "onDOMReady" event handler of YAHOO.util.Event rather than waiting until 
+  the "load" event of the Tooltip's parent window fires.
+
++ Deprecated "browser" property of YAHOO.widget.Module in favor 
+  of YAHOO.env.ua.
+
++ The "moveEvent" of a YAHOO.widget.Panel instance now also fires with the 
+  "endDrag" event of the its YAHOO.util.DD instance.
+
++ Updated modal functionality of YAHOO.widget.Panel:
+    
+    - The creation of a Panel instance's modality mask is now deferred until it
+      is initially made visible.
+
+    - Showing a modal Panel instance will now result in the Panel and its 
+      associated modality mask element having a higher z-index than all other
+      YAHOO.widget.Overlay instances and Overlay subclasses.
+
++ Updated the "underlay" configuration property of YAHOO.widget.Panel:
+
+    - The creation of the underlay element is deferred until the Panel
+      instance is initially made visible.
+
+    - For Gecko-based browsers on Mac OS X the underlay elment is always 
+      created as it is used as a shim to prevent Aqua scrollbars below a Panel 
+      instance from poking through it.
+
+    - For IE 7 (Quirks Mode) and IE 6 (Quirks Mode and Standard Mode) the 
+      underlay element is resized in response to a change to a Panel instance's 
+      "width" or "height" configuration properties, a change to the browser's 
+      font size or the firing of the contentChangedEvent (triggered by use of  
+      the "setHeader," "appendToHeader," "setBody," "appendToBody," 
+      "setFooter," or "appendToFooter" methods). 
+
++ Updated the "iframe" configuration property of YAHOO.widget.Overlay:
+
+    - The creation of the <iframe> shim element is deferred until the Overlay
+      instance is initially made visible.
+
+    - The <iframe> shim element is resized when a change to an Overlay 
+      instance's content is made at runtime via the "setHeader," 
+      "appendToHeader," "setBody," "appendToBody," "setFooter," or 
+      "appendToFooter" methods.
+
++ Updated the "buttons" configuration property of YAHOO.widget.Dialog:
+
+    - YAHOO.widget.Button is now an optional dependancy, and if included, each
+      button in a Dialog will be an instance of Button.
+
+    - The "text" property of each button now accepts HTML
+    
+    - The "handler" property of each button can now be set to:
+    
+        + A reference to a function that should fire when the button is 
+          clicked.  (In this case scope of this function is always its 
+          Dialog instance.)
+
+        + An object literal representing the code to be executed when the 
+          button is clicked.  The format is:  
+          {
+            fn: Function (The handler to call when the event fires.),
+            obj: Object (An object to pass back to the handler.),
+            scope: Object (The object to use for the scope of the handler.)
+          }   
+
+
+Added the following features:
+-----------------------------
+
++ Added ability for YAHOO.widget.Tooltip instances to have shadow:
+
+    - The shadow for a Tooltip is implemented by appending a new element as the 
+      last child of its root <DIV/> element:
+
+        <DIV class="yui-tt">
+            <DIV class="bd"> ... </DIV>
+            <DIV class="yui-tt-shadow"/>
+        </DIV>
+
+    - The code that creates the shadow element resides inside the Tooltip's 
+      public "onRender" prototype method.  To disable the creation of a 
+      Tooltip's shadow override the prototype of the "onRender" method:
+      
+      YAHOO.widget.Tooltip.prototype.onRender = function () {};
+      
+    - The actual creation of the shadow element is deferred until the Tooltip 
+      is made visible for the first time.
+
+    - A Tooltip's shadow element can be styled via two CSS classes:
+
+        + "yui-tt-shadow"  - Applied to the shadow element when it is created.
+        + "yui-tt-shadow-visible" - Applied to the shadow element when the  
+          Tooltip is visible; it is removed the Tooltip is hidden.
+
+    - The shadow element is only styled when using the new "Sam" skin, for
+      the previous default skin its "display" property is set to "none."
+
++ Prototype of all classes (Module, Overlay, Panel, Dialog, SimpleDialog,  
+  Tooltip, Config, and ContainerEffect) are augmented with 
+  YAHOO.util.EventProvider, facilitating subscribing to an instance's 
+  Custom Events by name via a "subscribe" method that is a direct member of 
+  the class.  For example:
+  
+    var oOverlay = new YAHOO.widget.Overlay("myoverlay");
+    
+    oOverlay.subscribe("show", onShow);
+
++ Added a new "bringToTop" method to YAHOO.widget.Overlay that places the 
+  Overlay on top of all other Overlay instances.
+
++ Added a new "bringToTop" method to YAHOO.widget.OverlayManager that places 
+  the specified Overlay instance on top of all other Overlay instances.  This 
+  method is called on each Overlay instance that is registered with an 
+  OverlayManager instance.
+
++ Dialog instances are now able to upload files should the Dialog instance's 
+  form contain <input type="file"/> elements.  PLEASE NOTE: If a Dialog 
+  instance will be handling asyncronous file uploads, its "callback" property 
+  will need to be setup with an "upload" handler rather than the standard 
+  "success" and, or "failure" handlers.  For more information, see the 
+  Connection Manager documenation on file uploads:
+  http://developer.yahoo.com/yui/connection/#file
+
++ Added a new "getButtons" method to YAHOO.widget.Dialog that returns an array 
+  containing each of the Dialog's buttons; by default an array of HTML <BUTTON>
+  elements.  If the Dialog's buttons were created using the 
+  YAHOO.widget.Button class (via the inclusion of the optional Button
+  dependancy on the page), an array of YAHOO.widget.Button instances 
+  is returned.
+
++ Added a "destroy" method to YAHOO.util.Config that sets all properties to 
+  null, unsubscribes all listeners from each property's change event and all 
+  listeners from the configChangedEvent.  The "destroy" method of 
+  YAHOO.widget.Module now automatically calls the "destroy" method of its
+  configuation object.
+
++ Added a "IFRAME_OFFSET" constant to YAHOO.widget.Overlay that controls how 
+  much the <iframe> shim should be offset from each side of an 
+  Overlay instance.
+
++ Added a new "syncIframe" method to YAHOO.widget.Overlay that syncronizes the 
+  size and position of the <iframe> shim to that of the Overlay.
+
++ Added a "ICON_CSS_CLASSNAME" constant to YAHOO.widget.SimpleDialog that 
+  represents the name of the CSS class applied to the element created by the 
+  "icon" configuration property.
+
+  
+Known Issues
+------------
+
++ "Sam" skin Panel missing left and right borders when declared with a height
+  ---------------------------------------------------------------------------
+  If the height of a Panel instance exceeds the total height of its header, 
+  body and footer elements, the space not filled with content will lack a left 
+  and right border.  Therefore, to set a Panel instance to a fixed height 
+  when using the "Sam" skin, apply the desired height to the body element, 
+  taking into account the height of the header and footer elements.  To set the 
+  height of a Panel instance's body via CSS:
+  
+  #mypanel .bd {
+    height: 100px;
+  }
+  
+  Or via JavaScript:
+  
+  oMyPanel.body.style.height = "100px";
+
++ Elements with scrollbars poke through Overlay instances floating above them
+  ---------------------------------------------------------------------------
+  There is a bug in Gecko-based browsers for Mac OS X where an element's 
+  scrollbars will poke through absolutely positioned elements floating above
+  them.  To fix this problem the "overflow" property of an Overlay instance's 
+  root element is toggled between "hidden" and "auto" (through the application 
+  and removal of the "hide-scrollbars" and "show-scrollbars" CSS classes) as its 
+  "visibility" configuration property is toggled between "false" and "true."
+  
+  PLEASE NOTE:  
+  
+  1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are 
+     applied only for Gecko on Mac OS X and are added/removed to/from the 
+     Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and 
+     "showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
+     
+  2) For Panel (and its subclasses) it is the underlay element, not the root 
+     element, whose "overflow" property is toggled between "hidden" and "auto."
+     The underlay element therefore acts as a shim to correct the 
+     scrollbar problem.
+     
+  3) For Tooltip instances using the "Sam" skin it is the shadow element, not 
+     the root element, whose "overflow" property is toggled between "hidden" 
+     and "auto."  The shadow element therefore acts as a shim to correct the 
+     scrollbar problem.
+     
+  4) Once the fix is applied the bug will reappear if the window loses focus.  
+     This can be remedied via Javascript by hiding and showing the Overlay 
+     instance when the window receives focus:
+
+        YAHOO.util.Event.on(window, "focus", function () {
+        
+            oMyOverlay.hide();
+            oMyOverlay.show();
+        
+        });

+
++ Scrollbars remain visible after an Overlay is hidden
+  ----------------------------------------------------
+  There is a bug in Gecko-based browsers for Mac OS X where an element's 
+  scrollbars and the scrollbars of its child nodes remain visible when its 
+  "visibility" property property is set to "hidden."  To fix this problem,
+  the "overflow" property of an Overlay instance's root element and child nodes
+  is toggled between "hidden" and "auto" (through the application and removal 
+  of the "hide-scrollbars" and "show-scrollbars" CSS classes) as its 
+  "visibility" configuration property is toggled between "false" and "true."
+
+  PLEASE NOTE:  
+  
+  1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are 
+     applied only for Gecko on Mac OS X and are added/removed to/from the 
+     Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and 
+     "showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
+  
+  2) There may be instances where the CSS for a web page or application 
+     contains style rules whose specificity override the rules implemented by 
+     the Container CSS files to fix this bug.  In such cases, is necessary to 
+     leverage the provided "hide-scrollbars" and "show-scrollbars" classes to 
+     write custom style rules to guard against this bug.  For example:
+  
+     To fix the scrollbars issue for an Overlay instance with an id of 
+     "myoverlay" whose body element has scrollbars applied by default:
+
+        #myoverlay .bd {
+        
+            height: 100px;
+        
+            /* Apply scrollbars for all browsers. */
+            overflow: auto;
+        
+        }
+        
+        #myoverlay.hide-scrollbars .bd {
+        
+            /* Hide scrollbars by default for Gecko on OS X */
+            overflow: hidden;
+            
+        }
+        
+        #myoverlay.show-scrollbars .bd {
+        
+            /* Show scrollbars for Gecko on OS X when the Overlay is visible */
+            overflow: auto;
+            
+        }        
+    
+     To fix the scrollbars issue for a Panel instance with an id of "mypanel" 
+     whose body element has scrollbars applied by default:
+    
+        #mypanel .bd {
+        
+            height: 100px;
+        
+            /* Apply scrollbars for all browsers. */
+            overflow: auto;
+        
+        }
+        
+        .yui-panel-container.hide-scrollbars #mypanel .bd {
+        
+            /* Hide scrollbars by default for Gecko on OS X */
+            overflow: hidden;
+            
+        }
+        
+        .yui-panel-container.show-scrollbars #mypanel .bd {
+        
+            /* Show scrollbars for Gecko on OS X when the Panel is visible  */
+            overflow: auto;
+            
+        }
+
+    ** For more information see 
+       https://bugzilla.mozilla.org/show_bug.cgi?id=187435
+
++ Flash Movies appear on top of Overlay instances
+  -----------------------------------------------
+  Flash movies can appear on top of Overlay instances in IE and Gecko-based
+  browsers.  To fix this problem, set the "wmode" of the Flash movie to either
+  "transparent" or "opaque" as indicated below: 
+
+  Via the <object> tag:
+
+    <object>
+        <param name="wmode" value="opaque">
+    </object>
+
+    <object>
+        <param name="wmode" value="transparent"> 
+    </object>
+
+  Via the <embed> tag:
+    
+    <embed wmode="transparent"> ... </embed>
+    <embed wmode="opaque"> ... </embed>
+
+    ** For more information see 
+       http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_15523
+
++ Overlay instances not rendered at correct z-index in IE
+  -------------------------------------------------------
+  In IE, when an Overlay instance is rendered inside a relatively positioned 
+  element the z-index of the Overlay instance is now relative to its 
+  relatively positioned parent element.  This is not a bug in the 
+  Overlay class, but rather a bug in IE where relatively positioned elements 
+  establish a new stacking context for their child nodes.  To avoid this 
+  bug it is recommend that all Overlay instances that need to be able to float
+  above any other element in the document be made direct descendants of the 
+  <body> element.
+
+  ** For more information see 
+   http://therealcrisp.xs4all.nl/meuk/IE-zindexbug.html
+
++ Header elements for Panel instances using "Sam" skin shrinkwrap in IE 7
+  -----------------------------------------------------------------------
+  In IE 7 (Standards Mode) if a Panel instance is created without specifying a
+  value for the "width" configuration property the width of the Panel's 
+  header element will shrinkwrap to the width of its text node.  To avoid 
+  triggering this bug in IE always specify a value for the "width" 
+  configuration property when using Panel.
+
++ Panel instances render at 100% of the browser viewport
+  ------------------------------------------------------
+  In IE 7 (Quirks Mode) and IE 6 (Quirks Mode and Standards Mode) if any of the 
+  child nodes of a Panel instance's root element have "layout" 
+  (http://msdn2.microsoft.com/en-us/library/ms533776.aspx) and no value
+  has been specified for the "width" configuration property, the Panel will 
+  render at 100% of the width of browser's viewport.  This bug will manifest
+  when using the "Sam" skin as layout is applied to the header, body and 
+  footer elements (by setting the CSS "zoom" property of the element to "1" ) 
+  in order to get the negative margins required for the rounded corners to 
+  render correctly.  To avoid triggering this bug in IE always specify a value
+  for the "width" configuration property when using Panel.
+
++ Panel instances render at 2px wider when using "Sam" skin 
+  ---------------------------------------------------------
+  For the "Sam" skin a Panel instance's rounded corners are created via the 
+  application of negative 1px left and right margins on the header, body and 
+  footer elements.  These negative margins will cause a Panel instance to be 
+  rendered at 2px wider than the value specified by the "width" configuration 
+  property.  Therefore, when using the "Sam" skin consider the negative left 
+  and right margins and subtract 2 from the value passed to the "width" 
+  configuration property in order to have the Panel render at the desired 
+  width.  For example, to render a Panel 300px wide, pass a value of "298px" 
+  to the "width" configuration property.
+
+
+*** version 2.2.2 ***
+
++ Clicking the close button of a Panel (or any instance of a Panel subclass) 
+  registered with an OverlayManager will no longer result in the Panel 
+  receiving focus.
+
++ Overlay instances registered with an OverlayManager will now correctly 
+  blur themselves when hidden.
+
++ Calling the "destroy" method of an Overlay instance will now result in it 
+  being removed from its OverlayManager instance(s).
+
++ The DOM event listener for the event defined by the "focusevent" 
+  configuration property of an OverlayManager instance is now removed from each 
+  Overlay instance when it is removed from its OverlayManager.
+
++ All subscribers for an Overlay instance's "focus" and "blur" events are 
+  now unsubscribed when it is removed from its OverlayManager.
+
+
+*** version 2.2.1 ***
+
++ Made the default scope for all Custom Events published by Module, Overlay, 
+  Panel, Tooltip, Dialog and SimpleDialog the widget instance.  Previously the 
+  default scope for Custom Events was inconsistent across classes; the default
+  scope for Custom Events published by Overlay was always the Overlay instance
+  whereas the Custom Events published by all of the other classes had no 
+  default scope.  
+
++ Added default scope for CustomEvents published by YAHOO.util.Config:
+  - Default scope for the "configChangedEvent" is now the Config instance.
+  - Default scope for Config property events is now the Config's owner (widget).
+
++ Panel and Tooltip now always convert the value of a DOM element's "tagName" 
+  property to uppercase before evaluating it.  This improves 
+  XHTML compatibility.
+  
++ Pressing the enter key while focused on a form field inside a Dialog will 
+  now trigger the "click" event handler defined by the Dialog's default 
+  button in IE and Firefox.  Previously, this behavior only worked in Safari 
+  and Opera.
+
++ Added a "yui" prefix to the default CSS class name for Module to be 
+  consistent with the other Container family widgets.
+
++ Container/Panel's underlay shadow is now defined as partially-transparent
+  black rather than gray.  This prevents the shadow from lightening the 
+  background color of elements beneath it.
+
++ Fixed memory leaks in Panel and Dialog.
+
++ The Drag and Drop library is now a truly optional dependency for Panel and its 
+  subclasses.
+
++ Panel "focus" and "blur" events are now fired when Panels are focused and 
+  blurred via the "focus" and "blurAll" methods of YAHOO.widget.OverlayManager.
+
++ Panel instances rendered without setting the value for the "width" 
+  configuration property will now have their "width" configuration 
+  property set to the value of the Panel's element's "offsetWidth" property 
+  when rendered.  This fixes an issue in IE 6 and 7 where Panels that are 
+  rendered without setting the "width" configuration property will only be 
+  draggable by mousing down on the text inside the header, rather than anywhere 
+  inside the header.
+  
++ Refactored the Container family including the Config class to improve 
+  performance, especially when working with a large number of instances in IE6.
