Tons of changes.
complete overhaul of the food and shield systems, and other game mechanics.
mountain caves with items and armor and decorations and a weapon and more
tar pits and fancy wood items
oven, windows, gold piles, and tons of home decor
animal taming, riding, etc
pause button, performance cleanup, save lag warning.
note that armor stands, riding animal, fist weapons, and several other changes were frequent flyers in the suggestions area.

at the same time, its the same as before in the sense that we still stop after plains and have nothing left to do except build bigger homes.
