Changes 2.1.16:
Unfortunate bug introduced in 2.1.15 that broke generated firewall script
for iptables in case option "use iptables-restore" was on is fixed in this
release. Additional checks were added to the generated script for iptables
to improve error detection and make sure the GUI properly detects when it
terminates with error. Support for load balancing with PF was also added.
