Protocols/MSNP/Reference/ProtocolTable

This table shows how protocol support has changed with clients over the years. Third-party and open-source clients are welcome to be added to the list, as long as they're grouped together (the table is sorted by Product Name, then Product Version; it is not sorted chronologically).

The information was obtained by running each client against an unofficial MSNP Dispatch Server implementation and inspecting the VER commands sent to the server.
