Ager's Amazing Mineshafts and Miner Companions (includes structures, NPCs and monsters)

All miners will now dig through any rock material of hardness 2 or less (ores are still unaffected). It expands the types of blocks they can break, but also means they can no longer dig through deepslate. Might add a separate deepslate miner in future update.

Armoured rock driller now digs three blocks in all four directions (previously only two blocks). He will also break any rock material block directly above his head.

Spawn weights on all mobs adjusted.
