0.05  2003-12-30  DCANTRELL  Applied mike@very.puzzling.org's patch for
                             comparing compiled regexps
0.06  2004-01-06  DCANTRELL  Added plugins, moved Scalar::Properties support
                             into a plugin (plugins were Jim Cromie's idea)
0.07  2004-01-07  DCANTRELL  Bugfix to avoid loading same plugin more than
                             once.  S::P plugin renamed so it would work with
			     this bugfix.  Clean-up of code.  Fix minor doc-bug
			     in lib/Data/Compare/Plugins.pod.

                             much better implementation.
0.11  2004-06-02  DCANTRELL  Now taint-safe - in taint mode there's no plugins

0.12  2004-11-09  DCANTRELL  Fixed recursion detection bug - wasn't decrementing
                             counter properly!  (thanks to Jenda for the bug
                             report)
