  The result is that you can now run the server in "normal" mode, and
then turn on debugging mode for one user, realm, group, whatever.  The
debug output can be directed to a separate file, so it doesn't go into
radius.log.

  Normal output can also be split up into different log files by user,
realm, group, etc.  The main radius.log file still exists for global
logging.

  I think the next release could be called 2.1. :)
