- Configuration file /etc/fail2ban.conf, failregex configuration

-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

-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!
