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.

Infested 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]

Light

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

Amethyst clusters

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

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.

Tags

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

Textures

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

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.

Caves

• 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.
