On 07.06.2007  the ASP.NET AJAX Control Toolkit team released an updated version.  You can download it from the http://ajax.asp.net web-site, and run samples built with it on the online samples page here.

The ASP.NET AJAX Control Toolkit is a free download and contains more than 40 additional AJAX controls and components that work on top of the core ASP.NET AJAX 1.0 release.  In addition to having Microsoft developers contribute, the project also has more than 15 non-Microsoft contributors adding great features and controls.
