the changes are for the better i guess. no longer have to dither. it doesnt have the slide left and right part anyways. you do a new step that is similar to the evelation. it is probably about two pounds lighter also. the weight of the dish is no longer supported by the elevation locking nut and plastic adjuster. few extra support bolts. the only thing that i saw that is a little weird is that the evelation adustment dial is at a 45degree angle downword. would make it a little difficult to see if you are standing above the dish
