Minecraft 26.4 Snapshot 3 is a Java Edition test build released October 6, 2026. Its main addition is the Ice Caves biome, with Ice Crystals, Icicles, Frostbite mobs, the Freezing effect, and Ice Balls. It also refreshes the Friends and multiplayer-player menus. To try it, enable snapshots under Minecraft Launcher → Installations; use a backed-up world or a separate test folder because test versions can corrupt saves.

What’s new in Minecraft 26.4 Snapshot 3?

The Java Team’s Minecraft 26.4 Snapshot 3 release notes introduce a cold-cave biome and related blocks, combat mechanics, and interface updates. This is a snapshot for Minecraft: Java Edition, not a final release.

Ice Caves bring a new Overworld biome

Ice Caves can generate beneath colder Overworld biomes. Packed Ice and Calcite make up much of the cave; snow may cover the floor, ores appear in Stone and Deepslate pockets, and Ice Crystals generate occasionally. Icicles hang from ceilings, while larger Packed Ice icicles can appear on ceilings or the ground. Strays and Frostbites can spawn alongside ordinary cave mobs. Glow Lichen does not generate in Ice Caves.

Ice Crystals and Icicles affect building and exploration

Ice Crystals are light-emitting blocks resembling Amethyst Clusters. They break if their supporting block is removed and can be placed in any direction. Icicles behave like speleothems: naturally growing, downward-pointing ones can reach five blocks, but growth requires the absence of nearby light and does not happen in the Nether. Pointed blocks break when exposed to nearby light or placed in the Nether. Falling icicles damage entities, and entities that land on them take extra damage.

How Frostbite, Freezing, and Ice Balls work

Frostbites switch between melee and ranged attacks

Frostbite is a zombie variant found in cold or icy biomes. It uses melee attacks at close range and throws Ice Balls at a distance when it has them. A melee hit applies Freezing. Frostbites can stand on Powder Snow and are immune to freezing and its slowing effects. If submerged long enough, they turn into ordinary Zombies; Zombies and Husks caught in Powder Snow turn into Frostbites. Frostbites drop Rotten Flesh and Ice Balls.

Freezing damages affected creatures over time

The Freezing effect makes players shake and gradually freeze, eventually causing damage, similar to Powder Snow. Leather Armor protects against freezing as it does in Powder Snow, but it does not prevent the effect from being applied or remove it. Mobs take extra damage while affected; mobs vulnerable to freezing take five times the damage.

Ice Balls can be used to brew a Potion of Freezing, Splash Potion of Freezing, or Lingering Potion of Freezing. To craft Arrows of Freezing, place a Lingering Potion of Freezing in the center of a crafting table and surround it with eight arrows.

Ice Balls are damaging projectiles

Ice Balls break on impact with a block or entity, apply knockback, and deal four damage to entities on impact. Their damage scales down with projectile velocity, so the listed impact damage is not a guaranteed amount in every hit.

What changed in Friends and multiplayer menus?

The Friends list has a refreshed design, search, and sorting by online status or alphabetically. The profile-name field in the Friends tab also searches. The Requests tab shows a search box when there are at least 15 requests. Selecting a player icon opens Player Options, grouping social actions such as friend requests, muting, and reporting. Muting hides that player’s chat messages until the next time the game starts.

The Social Interactions screen has been replaced by Other Players, and its keybind has been renamed to match. Other Players shows current players and some recently active players in multiplayer-open worlds, including LAN worlds, dedicated servers, and Realms. Open it from the pause-menu icon or press P by default. Blocking players is managed there.

The notes also include additional UI, control, mushroom-generation, and reporting-related fixes; see the official notes for the complete bug-ID list.

How to install and play Snapshot 3

  1. Open the Minecraft Launcher.
  2. Go to Installations and enable snapshots.
  3. Select the Snapshot 3 installation and launch it.
  4. Use a backed-up world or a separate test folder rather than opening a valuable main-world save.

Mojang warns: “Testing versions can corrupt your world, so please backup and/or run them in a different folder from your main worlds.” The snapshot notes also link a cross-platform server jar, issue tracker, and feedback site for server operators and testers.
