Release Java Edition Bug-fix update Patch of 1.2.1

Minecraft 1.2.5

Released on 4 April 2012, Minecraft Java Edition 1.2.5 is the final release of the 1.2 update. Mojang published it first as a pre-release at the end of March so that modders and Bukkit server owners could prepare. It adds shift-clicking in Furnaces and a better pick block key, and fixes chat crashes, world generation failures and cat behaviour.

Key takeaways

  • Final 1.2 release: 1.2.5 came out on 4 April 2012, after a pre-release at the end of March for modders and Bukkit servers.
  • Quality of life: shift-click works in Furnaces, pick block is easier in Creative mode, and Direct Connect remembers the last IP for the session.
  • Bug fixes: chat crashes, world generation failures, sound issues and a village door bug that could spawn too many villagers.

What changed

InterfaceShift-clicking an item in the inventory places it in the matching Furnace slot.
MultiplayerThe Direct Connect screen remembers the last IP address used during the session.
MobsWild Ocelots no longer behave like tamed cats, and tamed cats are less eager to sit and less patient.
FixesFixed several chat crashes, including one when pasting certain characters, and links in chat that were not detected or clickable.
ServersCommand matching is less greedy, so a command such as /stophammertime no longer stops the server.
ItemsUsing a stack of Bowls on a Mooshroom no longer consumes the whole stack.
BlocksPunching TNT with Flint and Steel now breaks it and drops it; right-clicking still ignites it.

Minecraft 1.2.5 FAQ

When was Minecraft 1.2.5 released?

On 4 April 2012, after a pre-release at the end of March. It is the final release of the 1.2 update, which began with 1.2.1 on 1 March 2012. The next major version, 1.3.1, followed on 1 August 2012.

Why did 1.2.5 have a pre-release?

Mojang released it early so that players using modded clients or Bukkit servers could update before the official release. Jens Bergensten said Mojang did not want to make it hard for people to play the game.

Should I update from 1.2.4 to 1.2.5?

Yes. 1.2.5 fixes crashes and world generation failures and is the most complete version of 1.2.
