New Air Pollution, Water Pollution, and Disease mechanics! By far the biggest and coolest change I've noticed. Mousing over a tile now tells you how much it affects each factor, if at all, whether positively or negatively. All these three elements now show up in your city's properties, alongside crime rate and such. For example, the Dye Maker building will give +5 air and water pollution per turn; Water Treatment Plants give -100 per turn to water pollution.
Note that the Disease stuff is not fully implemented so even have a high disease rate, nothing will happen yet. Nor is there anything to reduce your disease rate yet.
