Wooden recipes now use stripped wood instead of planks, except wooden axes which use normal wood. Showcase below.



Stone tools are now made of smooth stone, because everyone loves to smelt smooth stone, right?



Iron tools and armor are made of iron blocks instead of ingots. Buckets too.



Golden tools and armor are made of gold blocks. Very fun.



Diamond tools and armor are made of diamond blocks. Yes, that means that a chestplate costs 72 diamonds. full set costs 24*9=216 diamonds. Not including tools. But don't worry, netherite remains unchanged.

End City Lock
Until you obtain all diamond armor and tools, you cannot visit end cities. Well, you can, but it will not end well.
*You thought you could just loot some end cities and not care about expensive crafting? Better luck next time.*

Villager Lock
Until you get all netherite tools and armor (yes, even a netherite hoe), you cant trade with villagers. Again, you "can" but it will not end well for you, neither for the villager.
