The new wire protocol is FE-BE protocol.i.e. frontend-backend prototcol. It's the language in which postgresql server talks to a postgresql client application. So when you use libpq in your application, it talks this protocol over a TCP/IP or unix domain socket, with server. This is revamped in 7.4 to allow more functionality, efficiency and performance.
