Interesting, not sure if I like this new behaviour or not yet. It is definitely a bit buggy though - eg. if you hold alt and stretch horizontally and then press undo or (ctrl+z) it doesn't do a proper undo on some grouped objects. I tried it on some of the objects in the design gallery, eg. delivery van 1, camera etc. it seems to break most of them. If you do this on a complex illustration that you haven't saved you're screwed.
