Mercurial: good enough for now
Lately I’ve been trying out the Mercurial distributed version control system on some real projects.
I currently use Subversion for production stuff at work. It’s reliable, has great Trac integration, and is most likely to be known by other developers. (In fact, we hired a new person at work this fall who will be helping me with web development, and it turned out that Subversion was what he was familiar with. So I feel vindicated on that last point especially.)
