There are a couple of changes so far in the Prologues. If anything, nearly all the Prologue Episodes will have some changes or additions to the story because they were never really there in the Legacy Version/Old Story. Once development of Chapter I begins, there won't bebas many changes, and the amount of changes will most likely decrease as the main goal is to keep a lot of the Old Story intact, but slightly tweaked based on a lot of feedback... if any of that makes sense.
