Minecraft:Mineshaft	File:Old Mineshaft.png	Features generate differently if above ground. Cave spider spawners no longer generate if sky light is 8 or more. Wooden structures no longer generate if above is air or sky light is 8 or more. Minecraft:Rails in corridors are more complete if sky light is below 8.
Minecraft:Village	Template:Animate	No longer restricted by Minecraft:biome boundaries, meaning that a village that starts in a valid biome can now spread into an adjacent invalid biome. Now generates in taigas (but not variants). Village structures are now made with the wood type of that biome. In savanna villages, acacia log is used instead of cobblestone. Blacksmiths and churches always use cobblestone. Paths are now made with different material depending on the existing terrain. If replacing grass blocks, the path is made from Minecraft:grass path. If replacing water or lava, the path is made from Minecraft:planks. In desert villages, Minecraft:smooth sandstone is used instead of planks. If replacing sand, sandstone, or red sandstone, the path is gravel on top of cobblestone. In desert villages, sandstone is used instead of gravel and cobblestone.
