@ -26,6 +26,13 @@ Problems Corrected since version 1.4.6:
4) Handling of the LOGUNCLEAN option in shorewall.conf has been
corrected.
5) In Shorewall 1.4.2, an optimization was added. This optimization
involved creating a chain named "<zone>_frwd" for most zones
defined using the /etc/shorewall/hosts file. It has since been
discovered that these new chains contain redundant rules in many
cases so that the "optimization" is less than optimal. As a result,
the optimization has been removed.
Migration Issues:
None.
