On Monday, we went live with versions of the Atlas VSIs for RC/RTM, so now you can build an Atlas project whether you're running Whidbey Beta 2 or the RTM release (currently build 50727.42).  You'll find the links on http://atlas.asp.net, and from the instructions page, you can choose either the Beta 2 or RC/RTM version.

We've also updated the Atlas documentation and quickstarts on the Atlas site. 

Looking forward, we'd like to use the Atlas releases as a model for a community release and feedback process that features greater release frequency.  I'd love to hear your thoughts on how to make it a success.  Comment here or email me.
