There are undocumented changes for DOA3.2. Grap3 has found that a few characters' data was changed around but we don't know to what extent. In contrast, DOA3.1 has the given frame data and the looser tracking. The Sidestep moves aren't as much of a problem with the exception of Hayate's cartwheel which is just banned. There's some wonkiness with the stepping system - typically in regard to teching position as well - and is the key area of complaint of the SS. Personally speaking, I just accept it as the benefits outweight the glitchiness to me.
