Minecraft 1.13 Snapshot 18W06A

Todays snapshot brings in a complete rewrite of how world generation works behind the scenes, so that we can do some really cool things with it in the future & speed it up dramatically. It may be quite unstable in this first snapshot though, so as always: do not open worlds you care about in a snapshot without having a backup first. We can almost guarantee that any world opened in this snapshot will not work in the full 1.13 release.

A full changelog can be found on Minecraft.net:


  • Re-added /enchant command
  • Added a recipe book for the furnace
  • Rewrote the world generation system
  • Added command suggestions for entity selectors
  • Allow whitespaces in entity selectors & blockstate arguments
  • Added new item & block tags


We've spent the last few years (yes, years) rewriting the world generator completely from the ground up, and this snapshot finally has the first version that we have some kind of confidence in. It may not be much faster at first, but that's because we're playing it safe and want to just achieve "it works" before "it's fast". It might still be unstable, too, so watch out for that. It's the very first snapshot with it in, after all!


Now there's a recipe book for the furnace! Exactly like the existing crafting recipe books, you can unlock recipes as you play through the game and they will automatically appear in your recipe book for smelting. Mapmakers can customize the recipes with data packs, which allows them to add or completely change furnace recipes. "Fuel", the items that can be burned in a furnace, is not included in this and is still somewhat hardcoded currently.


... don't work in this snapshot. Sorry. We have plans to re-add them in a much more extendible way, but unfortunately we were not able to have that ready yet. You will be unable to open any world of type "customized" in this snapshot, it will tell you to revert to an old version to play in those worlds.


It's back how it was. We have shelved the /modifyitem idea that was supposed to replace /enchant and we will look into that again in a future update.

  • [................] x 10

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 dropdown 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).


Please report any and all bugs you find in Minecraft to bugs.mojang.com.


Snapshots can corrupt your world, please backup and/or run them in a different folder from your main worlds. 1.13 will have a lot of experimental snapshots that may break everything and smell funny. This may be one of those snapshots. This is what happens when Mojang are changing all the things!
