Actually, it has changed slightly - there are some new units in there that were added in some of the patches. However it is mostly balance tweaks, e.g support commanders don't explode in a nuclear fireball any longer (mainly because people were building an army of em and marching em into the enemy base as a nuclear suicide unit).
Supreme commanders still blow up in a nuclear fireball though, which is the most annoying thing imaginable - was playing a lan game and someone built the teleport upgrade on their commander and teleported it right into the middle of my base. If you leave it there it'll blow your base up from the inside out - if you destroy it KABOOM - bye bye base

Still don't think there's any defense against that one.
