Release Notes: IPv6 support was enabled. If iptables can't rebuild netfilter, the program doesn't die, but only logs information.
Release Notes: The /etc/authfail.conf file was added. A Setup.pl script was added to automatically install the program. A pid file is now created. The TERM signal is now supported by removing the pid file before exiting. Networks are now supported in the dont_add_into_database parameter.
