It hasn't changed, and I don't know why people are saying that most books don't have DRM. It is only a small minority.
Tor books is the largest publisher without it (owned by Macmillan). Otherwise everything is truly hard DRM either ACSM with epub or Kindle's. They are both more or less easily defeated though.
