Minecraft 26.1 snapshot 1

16 Dec 2025 Original Changelog

The first 26.1 snapshot is out, featuring data-driven villager trades and other technical changes.

Versioning

This is the first snapshot with the new version numbering system.

Mobs

Piglin inventories use slot indices 300 through 307, like villagers.

Villagers now have a new NBT boolean field: VillagerDataFinalized. It is set to true when VillagerData is populated, usually on spawn.

Splashes

Changed “Java 16 + 1 + 4 = 21!” to “Java 16 + 1 + 4 * 2 = 25!”.

GameTest

Added a new command-line argument: --repeatCount. It specifies how many times each test will be repeated. The --verify argument overrides --repeatCount, causing tests to run 100 times in total.
