Minecraft Pre-release 1.12.1-pre1

A 1.12.1 pre-release for Minecraft: Java Edition

We're all working very hard on 1.13, which will be a technical update to make the game run better than ever & easier for us to add super cool things later. But for now, we decided to create a small bugfix release for a security issue in 1.12.

If this pre-release goes well, we will release 1.12.1 tomorrow (Thursday, 3rd of August).


Changes in pre-release 1.12.1-pre1

  • Minor optimisations
  • Fixed bug MC-86016 - Some Mojang staff not mentioned in credits.txt
  • Fixed bug MC-119840 - Diamonds get moved into crafting slots on any chat message

Changes in snapshot 17w31a

  • Updated game credits
  • Fixed private bug MC-119011 - Security issue with recipe book

Please report any and all bugs you find in Minecraft to If nobody reports a bug, we can't fix it!


To get snapshots, open your launcher and go to the "launch options" tab. Check the box saying "Enable snapshots" and save. To switch between the snapshot and normal version, you can find a new dropdow menu next to the "Play" button. Back up your world first or run the game on in a different folder (In the "launch options" page).

Snapshots can corrupt your world, please backup and/or run them in a different folder from your main worlds.
