So I wasn't paying much attention around that update and for purposes of updating my old creative village, I'd like to add a route in which contains newer buildings. I'd really appreciate a list of what all of these are (eg cartographer building) - please and thanks!
There's a workshop building for each workstation block. They take biome into account, and I'm starting to think that certain ones are exclusive to those biomes. I've only ever seen a smokehouse in a savanna village, I've only ever seen a fisherman's hut in a taiga biome, and I've only seen a library in a desert biome.
There's the blacksmith as well, which aside from a building-style facelift is in exactly the same layout as before.
There's an animal pen. Oak-fenced in plains villages, spruce-fenced in taiga villages (although I can't remember now if I've seen one there or not). Desert villages use a standstone enclosure instead. I don't recall seeing one in savanna villages, but this might be by design because of the smokehouse building (it's on stilts with a small animal pen attached).
There's also a barn. Has hay, a cauldron with water, and an opening to a penned-in area for the animals to wander. If you've played modded with the Railcraft mod, it's sort of styled like the Train Station but a bit smaller.
Each village has crop-farm plots, of course. The crops grown are dependant on biome. Desert has wheat/beetroot and melons, taiga has carrots/potatoes and pumpkins and savanna/plains has wheat/beetroot/carrots/potatoes but no melons/pumpkins. Just about every building in a desert village has a cactus in a flowerpot.
village centers can be a well, a tree plaza, or a bell-stand (exactly what it sounds like, two pillars with a bell hanging between them). There's almost always a bell on the ground near wells and trees, and the village centers can appear multiple times in a large enough village (I'm assuming these are simply two villages that spawned too close, but I've seen up to 5 in what appears to be just one big village that sprawled extra widely because of terrain elevation differences).
The houses are mostly small houses, which are the same size as the old abandoned small houses in 1.12 (the ones with no lights and dirt floors). There appears to be about 4 or so variations, consisting of a bed and one side feature (crafting table, loot chest, chair, table-and-chair, or carpet). There may be more variations in desert villages, but I found them to be rather bewildering. There's also a grand house with a couple beds and a loot chest, as well as an apartment building that has 4 beds in a 2x2 2-floor layout. There are no equivalents, as far as I've seen, of the old 1.12 L-shaped big houses.
