Everyone's changing their version control system these days. Most seem to be moving from a centralized system, like CVS or Subversion, to one of the new-fangled distributed systems like Git and Mercurial.
FreeBSD, never the trend-setter, is leaving behind the crusty old CVS its source tree has been on for centuries, and upgrading -- to Subversion, the whipping boy of 2008! When rats like Rails start migrating away from a sinking ship, leave it to good old FreeBSD to grab that tiller, so popular five years ago.
On Reddit, there's a discussion, in which the sound reasons for the choice are outlined and attacked.
