The latest Visual Studio (VS) Community Tech Preview (CTP) is available via MSDN subscriber downloads.
The most interesting part for those that are already familiar with the March VS CTP will be inclusion of Visual Studio Team System (VSTS). You can find out the full details about VSTS via my earlier blog entry and the official VSTS site.
Tim Sneath reports from TechEd that the May VS CTP will include the (VSTS) client tools, but not the server tools. I would have found out myself, but the download still has 7 hours to go ;).
