The major new functionality is that the new one uses cfg80211, whereas the old 
one uses the WEXT calls.

It really is an improvement. It just needs a severe cleanup.

I warned you that this code was rough. It took me several weeks to get the old 
one "ready" for staging. I never devoted that effort to the new one, and you 
wanted it in a place where multiple authors could improve it.
