Wow, our User Experience team continues to amaze! They have just released an update to the BizTalk Server 2006 documentation that contains tons of new content. I'd list it all here, but there's just too much so check out the attached doc for the full run down. Also, if you don't already, you should monitor Luke's blog to stay on top of the new samples, tutorials, and doc refreshes they keep pumping out.
