subversion

My project definition says that I still got to document the specifics of SVN and CVS (git has been taken care of). Coming from the KDE camp, I'm already acquainted to Subversion to a certain degree, as the whole huge KDE repository switched from CVS in May 2005. (No one, including the SVN admin, did regret the switch).

Subversion (SVN) came up as a replacement for CVS - motto: "CVS done right" - and incorporates its centralized development methology and its straight-forward workflow, while improving on its weak parts. Compared to CVS, Subversion features good stuff like atomic commits, renaming, serverless diffs, symlink support and version-controlled directories, to name the most popular ones. It fulfills its role as a drop-in replacement brilliantly and has kinda deprecated CVS, at least for newly installed repositories. (That, of course, doesn't stop Linus Torvalds from claiming that centralized development methologies are outright wrong.)
