Minecraft is getting colder. Snow bricks and ice caves lead its winter previews.

Minecraft's next winter-themed game drop is taking shape in public testing. Mojang published Bedrock Preview 26.70.22 on October 28, adding more of the upcoming drop's features. It is a Preview changelog: these details should not be read as confirmation that the complete update has reached every regular Minecraft installation.

The latest build introduces snow bricks and associated building pieces. Mojang describes them as decorative blocks that do not melt. For builders, that makes the new material worth testing as part of a winter structure, rather than treating snow as scenery that only belongs outside the walls.

There is also a Cold archetype for sulfur cubes. Equip a cube with blue ice and its movement over water source blocks can create frosted ice. The update adjusts other winter features too, including the placement and behaviour of packed-ice building pieces.

Earlier testing established the larger setting: ice caves beneath cold Overworld biomes, icicles, ice crystals, and the hostile Frostbite. The September preview introduced that zombie variant and its freezing attacks. Those earlier notes provide context for the October additions without turning each testing build into a separate finished expansion.

If you want to experiment, keep your main world backed up and use a separate test world. Preview features can change, and a build designed to collect feedback is a different proposition from a stable server shared with friends. Our interest is in what the new materials let players build, once the testing settles.
