> There should be a way to version the binary protocol, CASSANDRA-5349 adds a message that breaks compatibility (QueryMessage) and the ticket half-handles versioning - it allows old clients to connect and execute queries (by always replying in the same version as the message sent by the client), it does not allow new clients to connect to old servers though.
