Minecraft 1.13 Snapshot 17W50A

It's almost time for the holidays, so this week is going to be the last week for snapshots this year. Therefore, let's cram as many snapshots as we can into this week!

A full changelog can be found on Minecraft.net:

  • Added new local coordinate type in commands using ^
  • Tags can now include other Tags (of the same type)
  • When overriding a tag, you can choose to replace instead of append
  • Things crash a little less easily than before. A little.
  • Added ████████████████████ (and of course ███████████)
  • Fixed bug MC-2340 - Redstone torches schedule updates when they should not, causing unreliable timings.
  • Fixed bug MC-5694 - High efficiency tools / fast mining destroys some blocks client-side only
  • Fixed bug MC-93468 - Water and lava flow affected by random ticks
  • Fixed bug [...............] x20



By default all tags append if another data pack created the tag. For example, if you try to override minecraft:wool you'll actually add to the list instead of replace it. If you add "replace": true to your tag definition, we will ignore the previous data pack and only your definition applies.


You can add #foo:bar in a tag value list to reference another tag called foo:bar. This can go as deep as you like, but if you end up trying to reference yourself then we will not load it.

You can only reference tags of the same type, so a block tag can't include a function tag.


When specifying coordinates in a command, you can now use ^ to specify local coordinates instead of world coordinates. The syntax is: ^left ^up ^forwards, where left/up/forwards is the amount of blocks in the specified direction.

For example, this is the block right in front of a players face: ^ ^1.62 ^1 (1.62 blocks up, where is where the camera is, and 1 block forwards)

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!
