Snapshot 12w42a is Now Out!

    • Screenshots
  • Tweaked Anvil
    • Cheaper to create – New crafting recipe
    • Minor visual changes: Made “Too expensive” indicator colored and changed “cost” indicator text and improved text field UX
    • You can repair tools using their material, but crafting new ones is cheaper – Good for enchanted tools, though
    • Named items are now labeled with italics
  • Bats no longer trample crops, trigger pressure plates, or trigger tripwire
