WARNING!
Fail2ban 0.7 is a complete rewrite of the 0.6 version, and if you
customized any of provided configuration or startup files
(/etc/default/fail2ban, /etc/fail2ban.conf, /etc/init.d/fail2ban), please
read relevant entry in /usr/share/doc/fail2ban/NEWS.Debian.gz.

WARNING!
Configuration file /etc/fail2ban.conf, failregex configuration
parameter specificly, were changed in 0.5.4-5 to close reported
security breach, and in 0.5.4-5.14 to close few other bugs.
updating from <0.5.4-5
Unless configuration file (or corresponding failregex'es) gets updated,
security breach is not closed and corresponding warning will be reported
by the fail2ban (in the log files).
updating from <0.5.4-5.14
Bugs #329163, #331695 dealing with changed iptables rules
outside of fail2ban were fixed in 0.5.4-5.14, and require upgrade of the
configuration file (fwcheck option was introduced) to take full
advantage of the problem solution (otherwise some problems might
persist)
Please review the configuration file and make appropriate changes.
ENJOY!
