Like all EXPEDITIONS updates, this update was tested and confirmed to NOT break saves/worlds. 

Missing items/blocks more likely as 4 Farmer's Delight addons have been removed.

My testing confirmed no world corruption but I cannot foresee all possibilities so it is recommended to backup your world files before updating.
