He could or could not be lieing... there is a mod called "Spigot" for a 1.3.2 server that allow 1.4.2 clients to join. The downside of this is you cannot use the new 1.4.2 items (Beacons, Pumpkin Pie, etc.) Therefore you are just playing Minecraft 1.3.2 on a 1.4.2 client.
A hero will rise up.
That'd what I did on my server. Just get Spingot.
