There is a new WinDbg version (6.6.7.5) available here (it was released yesterday – July 18th).
You can check out some of the new stuff here.

Be careful though, the previous version had more than a few bugs and problems. Hopefully, this version fixed some (if not all) of them.

I still haven’t had much time to check it more thoroughly, but you are more then welcome to try it out, just don’t forget to report back! 🙂

Update: I’ve checked whether there is a new verison of SOS for .NET Framework and there isn’t any. There is only a new SOS version for .NET Framework 1.1 (which was compiled about 11 days ago).
Anyhow, this is kind of annoying. I’m really looking forward to get a new version of the .NET 2.0 SOS with at least all the features that were in the 1.1 version and are missing in the 2.0 version.
