When upgrading from versions previous to 0.7, you will need to run
	echo -e '%unknown:*\n%con:*\n%all:*' >> /etc/dwunauth

When upgrading from versions between 0.7c and 0.9, you will need to change all
occurances of "%user" to "user". (Used in admin commands and external/internal
messages).
e.g.	%%con     =>     %con
	%tim	  =>	 tim

If /etc/dwunrc refers to "dwun-log.pid" this should be changed to "dwunlog.pid".

From version 0.95 onwards, the commandon scripts are sent SIGHUP (rather than
SIGTERM) if no commandoff script exists. Look for "trap" in commandon.

From version 0.95 onwards, dwunwait is no longer needed.
