Minecraft: Java Edition is rolling out Snapshot 21w08a to interested testers, and includes a host of tweaks and fixes to the last Minecraft snapshot. All of this is in the name of testing the upcoming Caves and Cliffs Update, which isn’t slated to release until Summer 2021.

The latest snapshot for Minecraft: Java Edition renames the recently introduced “grimstone” to “deepslate,” updates textures for deepslate and various ores, tweaks ore distribution in the world, and more. It’s a solid snapshot for any dedicated player that’s been exploring the new cave generation and changes coming in the Caves and Cliffs Update. Mojang Studios does mention, though, that iron is awfully scarce in this new snapshot. Another snapshot should be arriving shortly that fixes this issue.
