The majority of new features that are part of the CTP are centered around improvements in Team System, most notably in the areas of quality and testing. From Brian Harry’s blog,
This CTP delivers a mix of features supporting both scenarios - including an update MSF CMMI template, user definable links types, hierarchical work items, work item queries on links, an awesome manual testing tool and more.
Since I don’t need any of the features in this CTP, I’m going to stick with Visual Studio 2008. The next CTP should be out in about 3 months; when that happens I’ll take another look at it.
