'''[[Minecraft:Trading]]'''
* Changed the trading mechanism of librarians selling enchanted books.

*** Jungle and swamp villages do not generate naturally. Thus, players must breed villagers or cure zombie villagers in these biomes to access their trades.
** All tradable enchanted books now split to special books and normal books.
*** Special books have a specific enchantment with a fixed level, and are only available from master librarians with full XP.
*** Normal books have a specific enchantment without a fixed level, just like before.
** All enchantments used for [[Minecraft:crossbow]], [[Minecraft:fishing rod]], and [[Minecraft:trident]] are removed from trading.
