Larger screen is a "new feature" since we are talking about hardware. LTE would be a new feature as well. Not having a big piece of glass on the back seems like a new feature too (my iPhone 4S has had a cracked back for a couple of months). I know this may seem silly, but a new dock connector that is symmetrical and is easier to plug in without looking is a new feature as well. Also, something about a panorama camera, but I wouldn't call that a BFD)
