Changes

Blocks

Minecraft:Infested blocks

Light

• Changed the textures of the light block displayed in the inventory or when holding it.

Items

Minecraft:Amethyst clusters

• The item models for amethyst buds, except for the amethyst cluster, have been changed so they appear higher in inventory slots.

Mobs

Minecraft:Goats

• Screaming goats now use their ram attack more often than other goats.
• The pitch for the sound of baby goats ramming into stuff has been increased.

General

Minecraft:Tags

• Added Minecraft:raw gold blocks to the guarded_by_piglins block tag and the piglin_loved block tag.

Minecraft:Textures

• Removed the unused mouth textures from the Minecraft:axolotl textures.
• The Minecraft:goat's two ear textures have been changed to mirror properly.

Experimental

Changes have been made to the official Caves & Cliffs world generation preview datapack, which gives early access to the world generation coming in Minecraft:Java Edition 1.18.

Minecraft:Caves

• Cave carvers generate below Y=0 in Minecraft:ocean biomes.
• Increased the minimum size of noodle caves and carvers, to make them easier to traverse and less likely to break up into fragments.
• Noodle caves no longer generate above Y=30.

Changes in the ore distribution.

Minecraft:Ore distribution

• Reduced Minecraft:copper ore spawning a bit, to compensate for large ore veins.
• Large Minecraft:ore veins are slightly more rare and slightly smaller on average. They now vary significantly, meaning players can still find huge ore veins like the ones in previous versions.
• Increased chance of finding raw ore blocks in ore veins.
• Removed Minecraft:deepslate blobs above Y=0.
• Extended the vertical range of the smaller blobs of Minecraft:iron ore, to make it possible to find iron in caves near the surface.
• Slightly reduced the amount of normal-sized iron blobs, to compensate for large ore veins and the increased range of smaller blobs.

Trivia

• This snapshot lacked an image when the changelog was released on Minecraft.net. The alt text that appeared said "A goat standing on a hill. Very regal.". Image still can be accessed via the link on the page.
• Ore distribution image contained hidden messages.
  • The ore distribution chart has upside down black text in the deepslate area that said: "Yes the first message is still here, ButTemplate:Sic upside down".
  • A vertical line of text can be found in the coal area, saying "Someday I'm gonna run out of space to hide these messages".
  • "We must stop messing like this!" can be found in the border of the new ore distributions image.
• This is the last snapshot which can be launched with Java 8 - Java 15.
