Release Notes: Support for UDP tunneling (in addition to the existing TCP tunneling) has been added. UDP datagrams are sent over the persistent connection and may utilize encryption. The command line invocation has been modified to accommodate the new functionality.
Release Notes: The SSL server socket had not been configured to require client authentication. This potentially allowed any PrivateServer to connect to a PublicServer. This has been fixed.
Release Notes: Secure socket layer (SSL) support has been added. CLOSE requests are now sent from the PublicServer to the PrivateServer. The documentation has been improved.
