Changes:
This release is the culmination of three years of heavy development. It adds "virtual server" support, IPv6, and a new policy language ("man unlang"). All common EAP types can be used, including experimental support for EAP-FAST and EAP-TNC. MAC address authentication and VLAN assignment can now be done using the VMPS protocol. Limited HUP capabilities have been added, along with updated documentation and examples. The server is much easier to install, configure, and debug.
