1.12-pre6 is the sixth pre-release for Java Edition 1.12, released on May 29, 2017,[1] which adds the ability to see credits from the menu screen.


Menu screen
  • Added the ability to see credits by clicking the copyright text.



Command blocks
  • Tab-completing command names in command blocks will no longer add a / prefix.
  • "Chief fess" and "base fess" banners are now just "chief" and "base" banners.

Non-mob entities[]

Minecarts with TNT
  • No longer instantly explode when hit with fire charges; instead, they explode as if primed by an activator rail.


  • Skipped functions (when the conditional fails) is now considered a failure (for example in command blocks).
  • Many pieces of text are now translatable, where previously they were hardcoded English.
    • The full list of changes can be found here.
  • Optimized recipe book and Creative inventory searching, especially when using mods.
    • Namespaces (e.g minecraft:stone) are no longer considered for searching.
  • Optimized chunk loading, as the previous pre-release slowed it down.
