originally following command was used to add header to all config files:
sed -ie '/# Author/ i\# Please report vulnerabilities to fail2ban-vulnerabilities at lists dot sourceforge dot net\n# and see http://www.fail2ban.org/wiki/index.php/HOWTO_Seek_Help for generic bug-reports.\n#' action.d/* filter.d/*
but it would be overkill ATM causing havoc in user-tuned configs -- postponed for now
Also adjusted the release date for today (by mistake in 1 commit ... sorry)
