Snapshot for




12w42a is the fourteenth snapshot released for 1.4.2.



  • Server IPs can now be individually hidden
  • Changed repeaters
    • When powering the either side of a repeater directly with another repeater, it will lock the current state of the other repeater until the signal to the powering repeater is turned off.
      • If a repeater that is on is locked, it will stay on.
      • If a repeater that is off is locked, it can not output a signal
    • When locked, the repeater's second torch will no longer be visible and a bar textured similarly to bedrock will appear
  • Anvil tweaks
    • New crafting recipe, now is 31 iron ingots instead of 55
    • Minor visual changes
    • The player can repair tools and armor using their source material. To get a tool or piece of armor to its maximum durability when it is nearly broken, one must use four of its source material (wooden planks, cobblestone, iron, gold or diamonds). However, hoes are not able to be repaired.
    • Reduced experience level cost
  • Bats no longer trample crops, activate pressure plates or tripwire
  • Updated language file
