Well, it is February right now, but nevertheless the ASP.NET team has released the January CTP build of Atlas. There are announcements and more information by ScottGu and Nikhil K. Nikhil calles the release “M1 Refresh” hinting at that the changes are not as drastic as they were with the December CTP, but some bugfixes and some new features that are rather under the hood. Go and play with it!
Update: The Atlas wiki has been updated for the January CTP.
