Mojang released Minecraft 26.4 Snapshot 3 on October 6, 2026, the third test build for the upcoming 26.4 update. The snapshot introduces the Ice Caves biome and a new hostile mob called the Frostbite, expanding the winter-themed content drop first shown during Minecraft Live.
Ice Caves biome
The new Ice Caves generate underground in cold regions. They feature ice crystals and glittering icicles that give the caverns a distinct visual identity compared to existing cave types. The biome adds variety to subterranean exploration in snowy and frozen surface biomes.
Frostbite mob
The Frostbite is a zombie variant adapted to freezing conditions. It spawns in the new Ice Caves and shares the general behavior profile of other zombie-type mobs — melee attacks, burning in daylight, and converting villagers — but with visual and mechanical tweaks suited to its environment. Details on unique drops or abilities remain limited in this snapshot.
Context from earlier snapshots
Snapshot 2, released prior to this build, focused on technical improvements: render distance fog was reworked, a new celestial occluder was added for sky rendering, and the F3 debug screen received a redesign. Snapshot 3 shifts back to content additions after that engine-focused release.
Winter 2026 game drop
Both snapshots belong to the winter 2026 game drop, a content package Mojang teased at Minecraft Live. The drop appears structured around cold-weather biomes and mechanics, with Ice Caves and Frostbite representing the first major biome-and-mob pair revealed for this cycle.
How to test
Java Edition players can select "26.4-snapshot-3" from the version dropdown in the official launcher. As with all snapshots, worlds opened in this version may not be compatible with future releases or stable versions. Back up saves before loading them in a snapshot build.
What remains unclear
Mojang has not yet published a full changelog for Snapshot 3 beyond the headline features. Smaller adjustments — block states, loot tables, advancement triggers, or technical fixes — typically accompany each snapshot but were not detailed in the initial announcement. The timeline for subsequent snapshots and the full 26.4 release date have not been confirmed.
