Beta 2 of VS 2010 is released. This is supposed to be the final release before the official launching in March 2010.

Visual Studio Team System (VSTS) does not exist anymore as a terminology in VS 2010. In the 2008 version, different Team Editions where available:
– VSTS Team Suite
– VSTS Developer Edition
– VSTS Test Edition
– VSTS Architecture Edition
– VSTS Database Edition
In addition to that you had the VS 2010 Professional Edition which contained all the basic VS features without any Team features.

Well, that was a lot of naming and caused a lot of confusion when it came to licensing.
MS has made a decision to ship 3 editions starting VS 2010 and no more is in use the term VSTS. These editions are:
– VS Ultimate
– VS Premium
– VS Professional
All previous VSTS 2008 team editions (plus more) features are still there but under the 3 above versions.
