In this version:

• Empty and invalid source and destination qualifiers are now detected in the rules file. It is a good idea to use the 'shorewall check' command before you issue a 'shorewall restart' command be be sure that you don't have any configuration problems that will prevent a successful restart.
• Added MERGE_HOSTS variable in shorewall.conf to provide saner behavior of the /etc/shorewall/hosts file.
• The time that the counters were last reset is now displayed in the heading of the 'status' and 'show' commands.
• A proxyarp option has been added for entries in /etc/shorewall/interfaces. This option facilitates Proxy ARP sub-netting as described in the Proxy ARP subnetting mini-HOWTO. Specifying the proxyarp option for an interface causes Shorewall to set /proc/sys/net/ipv4/conf/<interface>/proxy_arp.
• The Samples have been updated to reflect the new capabilities in this release.
