A couple of weeks ago we decided to bring in Sourcegear Vault as version control system to replace Visual SourceSafe. So far with great results. And now Erik Sink - software developer at SourceGear - blogs about the upcoming release of Vault 3.0 and its features. As this will be a major upgrade, pricing details will be announced soon.
Erik has also a interesting list of articles on "Source control HOWTO". Currently he's at Chapter 5 and writing Chapter 6. Highly recommended reading if you're into SCM!
