a) An IP address, interface or subnet may be preceded by "!" to
   specify complementation. For example, !192.168.1.2 means
   "all hosts except 192.168.1.2".

b) The CLIENT(S), PORT(S) and CLIENT PORT(S) columns in the
   rules file may now contain a comma-separated list.

   Example:

   ACCEPT	loc	fw	tcp	ssh,ftp,www

   This is equivalent to the three rules:

   ACCEPT	loc	fw	tcp	ssh
   ACCEPT	loc	fw	tcp	ftp
   ACCEPT	loc	fw	tcp	www

c) Shorewall is now more rigorous in parsing the OPTIONS column
   in the /etc/shorewall/interfaces file.
