1.12-pre6 is the sixth pre-release for Java Edition 1.12, released on May 29, 2017,^[2] which adds the ability to see credits from the menu screen.

Title 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.

Banners

• "Chief fess" and "base fess" banners are now just "chief" and "base" banners.

Minecarts with TNT

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

Functions

• Skipped functions (when the conditional fails) is now considered a failure (for example in command blocks).

Language

• Many pieces of text are now translatable, where previously they were hardcoded English.
  • The full list of changes can be found here.

Optimizations

• 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.
