Microsoft Messenger for Mac

MSNP on WebTV (MSNTV)

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.

MSNP1 through MSNP8

This table shows client protocol support for the "old style" clients that only supported core Messaging features.
