Will a 2.1 server still talk to something that old?
No that won't work. 1.8 clients have added code to handle the protocol changes with 2.x servers. There were a number of bug fixes related to corner cases in protocol interoperability, so it is recommended to use at least 1.8.5 clients, but 1.8.6 is better.
