21w18a is the twentieth snapshot for Java Edition 1.17, released on May 5, 2021,[1] which makes changes to goats and experimental ore generation, as well as fixes some bugs.
Changes
Blocks
- Instead of breaking instantly, they now take half of the time to break compared to their regular counterparts. They still have no assigned tool.[2][3]
- Changed the textures of the light block displayed in the inventory or when holding it.
Mobs
- 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
- Added raw gold blocks to the
guarded_by_piglinsblock tag and thepiglin_lovedblock tag.
- Removed the unused mouth textures from the axolotl textures.
- The 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 Java Edition 1.18.
- Cave carvers generate below Y=0 in 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.

Ore distribution
- Reduced copper ore spawning a bit, to compensate for large ore veins.
- Large 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 deepslate blobs above Y=0.
- Extended the vertical range of the smaller blobs of 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, But [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.
