I am going to spend the next couple blog entries catching up to the latest news. As you know, ASP.NET AJAX RTMed (release to manufacture) a couple days ago. This is definitely great news for those involved in developing "web 2.0" apps. After speaking with an ex-colleague of mine from my previous workplace, they were definitely excited about this as it meant the relative lockdown of the core framework. (Reference back to the major changes involved when the product moved from CTP to Beta of Atlas). In any case...
Just a couple days after the release, The Microsoft AJAX Library Cheat Sheets from ASP.NET Resources have been updated with the latest changes from previous versions of ASP.NET AJAX. Enjoy!
