We're now drawing to a close with 1.12, with hopefully one of the final
pre-releases. We're aiming to get the full 1.12 release out to you all very
soon, so depending on how todays pre-release goes we may have a date for you
shortly.
Changes in 1.12 pre-release 6
Optimized recipe book & creative inventory searching a lot, especially
when using mods
Made a bunch of text translatable, where previously they were hardcoded
English
Optimized chunk loading, a previous pre-release slowed it down :(
Added the ability to see credits by clicking the copyright text in the
title screen
Technical: Skipped functions (when the conditional fails) is now
considered a failure (for example in command blocks)
Technical: Tab-completing command names in command blocks will no longer
add a / prefix.
