As you know, the team has been very busy working on controls for the upcoming Silverlight 2 Beta 1 release. Working on a new platform, with new tools, doing things that have never been done before is more than enough to keep us busy.
But we wanted to make sure we kept some focus on our AJAX Control Toolkit users. As such, we pulled together some top-requested bug fixes as well as all the fixes we've recently gotten from our users, and have released the 20229 version of the Toolkit. Thanks to all of our users that have been submitting patches - keep it up!
