It appears the amphibious attack penalty has been increased from 20% to 50%. At least when I attacked a European colony from the sea it was 50%. Previously the penalty was 20% when the REF attacked me but I haven't myself used an amphibious attack before (I never needed to before but now the AI is too strong to attack from land).
Are there other undocumented changes?
