http://www.telerik.com/products/aspnet-ajax/whats-new/release-history.aspx

• No new features. A list of fixes is available in the Version Notes.

• Added: New ShowOnTopWhenMaximized property for RadWindow which sets big z-index to the maximized RadWindow only when set to true

• Added: New OnClientResizeStart client event for RadWindow

• Added: OnClientBeforeClose event for RadWindow

• Added: Live resize implementation - the IFRAME is not hidden when RadWindow is dragged and resized

• Added: New Opacity property

• Improved: The controls in the RadWindow's ContentTemplate are available to the page without using FindControl method

• Improved: When RadWindow is used with ContentTemplate, it automatically repaints its children when shown

• Improved: When RadWindow with ContentTemplate is being autosized, a loading sign is shown

• New AnimationDuration property

• Added ability to clear the cached properties when cloning RadWindowManager

• CDN support --Starting with the Q3 Service Pack 1 release you will be able to load the control scripts and skins from the Telerik CDN

• New Windows7 skin

• ContentTemplate – ability to load content (controls) from the current page instead of showing a different page. A detailed online demo is available below:http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx

• If you have multiple window managers on the page, you can call radalert, radconfirm and radprompt for each individual instance (manager.radalert())

• RadWindowManager when updated with AJAX keeps its Windows collection properly

• Improved AutoSize functionality

• Animation enabled with AutoSize (when server-side Animation property is called, or when client method is called with extra param - oWnd.autoSize(true)

• Added jQuery animations

• Changed CSS naming convention

• New property - AutoSize. When set to true, RadWindow will automatically adjust its dimensions according to the size of the content page in window.onload. You can optionally call the method with argument true - this will make the autosizing perform an animation while adjusting the size. Note, that in case you have already set the Animation property, you should explicitly call autoSize in the OnClientPage load event because only setting Animation and AutoSize in markup will not work - autosize requires the animation to be always resize.

• Right-to-Left Support

• Changed RadPrompt return handler to return null instead of empty string when the Cancel button is pressed (like the default browser prompt does)

• Added support for automatic focus on the first button when a RadAlert or a RadConfirm dialog loads (so that user can close it by hitting Enter on the keyboard). RadPropmt already has such support.

• IE - Improved on a problem with IE not hiding the content of a RadWindow when moved or resized which resulted in the window content iframe beginning to consume the mouse events.

• Added support for restriction zones for windows

• Implemented a new MOVE mechanism for RadWindow. The new mechanism offers improved performance and fixes an issue with IE in Windows Vista.

• Added methods to the window client API to allow moving and setting size to windows.
