Recipe book

  • The recipe for crafting mossy stone bricks from moss blocks or vines is now unlocked with moss blocks or vines, respectively, rather than mossy cobblestone.

  • The recipes for smelting and blasting ores into their respective materials are now grouped by ore type (i.e. smelting coal ore and deepslate coal ore are grouped).
    • For iron, gold, and copper, the recipes for smelting and blasting their raw materials into ingots are also grouped with their respective ore smelting and blasting recipes.
  • The recipes for crafting copper ingots from copper blocks and waxed copper blocks are no longer grouped.[3]

From released versions before 1.17
