Two more:

  - svn groups changes into revisions, so that they can be considered
    together, CVS versions individual files.
  - subversion tracks renames/moves correctly,
  - subversion commits are atomic, so you never have to worry about
    all of your stuff making it into the repos. at the same time [if
    you've never had to un-muck this, count yourself blessed!] ,
  - svk, which allows disconnected development while still commiting
    your work to a repo at natural points along the way (you can
    revert, branch, etc.... to your hearts content).

[yeah, that's 3, err, 4. Math is hard.]
