Minecraft Preview 1.20.30.20

• Librarians from different biomes now sell different Enchanted Books
• Master Librarians with full XP are guaranteed to sell a special enchantment, which is different in each Village biome
• This means that players must visit all seven Village biomes to get the full set of Villager enchantments
• There are two secret Village biomes where Villages do not generate
  • A player must build these Villages to access their trades!
• Some enchantments have been removed from Village trading and must be found in other ways

Wandering Trader

• Some players felt that the Wandering Trader had unfair prices and didn't sell many useful items. We have lowered their prices, added more trades, and increased the amounts available. The Wandering Trader will also now buy useful items from players, so it's possible to help them on their journey by giving them supplies even if you don't feel like buying anything.
• As this is an experiment, we would really appreciate your feedback as work continues and to help us decide on the future direction for Villager trades!

• Wandering Traders now have lower prices and have a higher amount of each item in stock
• Wandering Traders now sell Logs
• Wandering Traders can now buy many items, instead of only selling
