   Note: because ban-time is dynamic, it was removed from jail.conf as timeout argument (check jail.local).
 
 ### Enhancements
+* algorithm of restore current bans after restart changed: update the restored ban-time (and therefore 
+  end of ban) of the ticket with ban-time of jail (as maximum), for all tickets with ban-time greater
+  (or persistent); not affected if ban-time of the jail is unchanged between stop/start.
