I recently got an announcement for Perforce about their new Git Fusion product. I never really loved Perforce as a source code management system (I probably didn't used it long enough to get used to it like I did with StarTeam, SVN, and Git); but I love how the company is building new products on top of the Perforce foundation. This summer I caught a demo of their web content management product Perforce Chronicle and was impressed. You don't normally see sophisticated versioning and staging functionality like that in a CMS in that price point.
Nice work Perforce!
