Minecraft 1.17 Snapshot 21w15a – Patch Notes, Release Date, Time (Today, April 14) – DualShockers

Minecraft has witnessed exponential growth over the years, especially in the past few months, with many streamers and millions of players playing the game on a daily basis. The game is all set to receive the Caves and Cliffs Update later this year, which will be adding tons of new biomes, mobs and much more.

While there is still some time to go for the Caves and Cliffs update to release, Mojang Studios regularly releases some of the updates via snapshots and Bedrock beta updates. The next Snapshot that slated to arrive in the game is 21w15a and here is all you need to know about it.

When will Minecraft Snapshot 21w15a release?

Minecraft Snapshot 21w15a is now live and available for download.

Minecraft Snapshot 21w15a – Patch Notes

Here are the patch notes of Minecraft Snapshot 21w15a.

The riskier and technically more complex world generation changes for the Caves & Cliffs update will be shipped in a later update and have been switched off in this snapshot. This means:

  • World height has been switched back to the 1.16 levels
  • Noise caves and aquifers have been switched off
  • Cave and ravine carvers have been returned to their old settings
  • Crack carvers have been switched off
  • Ore distribution has been returned to the 1.16 setup
  • Copper now generates between the bottom of the world and height 192, being most common around height 96
  • Tuff now generates in blobs between heights 0 and 16
  • Worlds created in snapshot 21w05b or any earlier version can now once again be opened
  • Worlds created in any version between snapshot 21w06a and 21w14a can no longer be opened

THE CAVES & CLIFFS PROTOTYPE DATA PACK

You can still try out the world generation for the later update using a datapack which activates the changes as an experimental custom world:

  • Download the data pack
  • Launch the game, go to the “Create New World” screen, and click the “Data Packs” button
  • Drag the downloaded zip file onto the Minecraft window
  • The game will ask you if you want to add the data pack – click “Yes”
  • Click the play arrow on the data pack that just appeared in the list – this will move it to the list on the right-hand side of the screen
  • Click the “Done” button and continue creating your world as normal

Keep in mind that the world you create with the data pack will be flagged as experimental by the game, and such worlds are not guaranteed to work in future versions. Also, please note that you can’t add data packs that change the world generation to existing worlds, so you must create a new world to access the experimental features.

  • Goats will ram anything that moves… and also armor stands
  • A crinkly, crunchy sound now plays when Bone Meal is used

  • Goats will avoid walking on Powder Snow

BUILDING BLOCKS TAB

  • All ores have been reordered to be in the same location in the creative inventory
  • Compact forms of raw and refined underground materials have been reordered
  • Added the Marker entity
  • Added /debug function
  • selector and nbt chat components can now configure separators between elements
  • Servers can now customize a message to display when prompting players about custom resource packs

MARKERS

Markers are a new type of entity meant for custom use cases like map making and data packs.

  • Only exist on the server side, are never sent to clients
  • Do not do any updates of their own
  • Have a data compound field that can contain any data

/DEBUG FUNCTION

New debug subcommand executes command with same syntax as function

  • Every executed command, message (even if it would be normally invisible), result or error is stored to file
  • Cannot be run from inside functions

CHAT COMPONENT SEPARATORS

  • Components that print lists of names, like selector or nbt can now override separator (“, ” by default) with separator element
  • Examples:
    • {“selector”: “@e[type=chicken]”, “separator”: “|”}
    • {“nbt”: “CustomName”, “entity”: “@e[type=chicken]”, “interpret”: true, “separator”: {“text”: “*”, “color”: “red”}}

CUSTOM SERVER RESOURCE PACKS

When require-resource-pack is used in server.properties, there’s now an option for servers to add a custom message.

  • A dedicated server can configure additional message to be shown on resource pack prompt (resource-pack-prompt in server.properties, expects chat component syntax, can contain multiple lines)
  • MC-203855 – A geode configured_feature causes a crash when use_alternate_layer0_chance is used with no entries in inner_placements
