It's a great pleasure to announce the beta 1 of ASP.NET AJAX. It is a major release of the product formerly known as
Prince Atlas. There are too many changes to enumerate here (we basically remodeled the house), but the idea is to provide a rock-solid core and continue to innovate with the value-add CTPs. I'll blog in the next few weeks on some of the new features, and the first one will be the compat layer, which has been completely redesigned based on your feedback.
We're already hard at work on the next release. I'll keep you posted.
http://ajax.asp.net is the new url for Atlas/ASP.NET AJAX
