As you perfectly know (for example from Brian's blog, and probably hundred others), Orcas shipped. I'm extremely proud, because this is the first big MS product, that I was involved from the beginning. Noone denies importance of the Msscci provider, but the weight of Visual Studio is thousand times bigger than this PowerTool :).
The biggest feature I was involved with, is folderdiff, which I hope you will find useful. Though I'm not sure if I don't use Annotate more often :) And of course we will all benefit from the amazing performance improvements.
Here is list of all new things in this release. Over next days I will blog about smaller features that are not so widely known, but should make life of all users easier.
