In fact, when CVS was released,  CVS was a major new innovation in software configuration management <http://www.dwheeler.com/innovation/innovation.html>.  However, CVS is now showing its age through a number of awkward limitations: changes are tracked per-file instead of per-change, commits aren't atomic, renaming files and directories is awkward, and its branching limitations mean that you'd better faithfully tag things or there'll be trouble later.   Some of the maintainers of the original CVS have declared that the CVS code has become too crusty to effectively maintain. These problems led the main CVS developers to start over and create Subversion.
