2002 introduce the post processing. I got to use Cool Edit Pro and even Adobe Premiere for that purpose (Cool Edit having trouble with big track). Easy to equalize and add effects to music!
Also there is Fruity Loops, but I didn't use it since there is no common markers and track as i was used to. I think Fruity Loops is made for people who never done music before.
Propellerheads release ReBirth 2 : the new drumkit (tb909) allows better drum line to be done.
And finally, I use a new MP3 compressor, way much better, quieter and cleaner than the old Xing (was easy to outmatch, to be honest!!)
