Release Notes: iodine now does automatic probing of maximum accepted size on downstream data, and the server will fragment using this value. This enhanced throughput and ease of use because big packets like SSH login will work even if relay only allows 512 bytes. iodined now also replies to NS requests and can relay other queries to another DNS server on the same host. The client also uses one more bit of data per byte (base64) in upstream data, if accepted by the relay.
Release Notes: Multiuser support was added for up to 8 users simultaneously. Authentication was added, and a password is entered as an argument or on stdin. A manpage was added. "make" targets were added for "install" and "uninstall". The DNS code was cleaned up. More test cases were added. The directory structure was changed.
