The Towns update.

These would be like way bigger villages, and would only spawn in very flat areas. Bricks and Stone would replace cobblestone, there would be more types of wood, likely corresponding with the nearby biomes. There would be better loot, more villagers, more villager trades, and some of the villagers would already be leveled up to iron or farther. More iron golems, more lighting, and copper doors for better security. There could be four town types: Savanna, Desert, Oak/Flower Plains, and Snowy plains biomes. There should also be a swamp update with more flora and fauna such as algea and rushes of some sort. Also, there could be more pillager structures to balance out the villager ones.
