I've noticed that on the forums there is a list of the animal companion and familer changes. The creatures used in wildshape have also been changed, though the changes are not mentioned anywhere i can find. Would it be possible for a list to be put up please?

Yes, it would be possible!

I just got back from vacation, so I don't know if somebody has put one up while I was away, but if they haven't I'll look into it.
