In 2.2, if you go to Firewall->Virtual IPs and try to add an IP alias on the loopback interface, when you click the submit button, you get a message stating:

The following input errors were detected:

For this type of vip localhost is not allowed.

This works in 2.1.4. This change made it so it's no longer allowed in 2.2:

Adding a virtual IP config to config.xml and rebooting ends up working properly. It just doesn't work to add one through the web interface.
