Updated October 23, 2026. Minecraft's winter update is getting more practical for builders. Released on October 20, 2026, Java Edition 26.4 Snapshot 5 introduces a full set of Packed Ice Bricks, a new way to earn an advancement while fighting a Frostbite, atmospheric sounds for ice, and an experimental Windows display option. Server administrators also have important network-protocol changes to watch before trying the snapshot with friends.
These additions are part of the still-in-development fourth game drop of 2026, not a finished stable Minecraft release. Mojang has already been testing Ice Caves, Frostbites, brittle ice, and other frozen features in earlier snapshots. Snapshot 5 expands that work rather than introducing the entire winter biome for the first time. Here is what is genuinely new, what you can build, and how to test it without putting your main world at risk.
What is new in Minecraft 26.4 Snapshot 5?
The official Java Edition changelog identifies Packed Ice Bricks as the headline addition. It also introduces the Adventure advancement What Goes Around Comes Around, adds a conditional ambient sound to normal Ice blocks, and includes a Windows-only experimental video setting called Prefer DXGI Present. Under the hood, Mojang revised how login packets negotiate encryption and compression, updated data and resource pack formats, and fixed several world-generation, mob, interface, and dedicated-server bugs.
The immediate attraction is visual. Existing ice gives Minecraft builders smooth, translucent surfaces, but Packed Ice Bricks add a deliberate masonry pattern that suits ice fortresses, frozen villages, winter castles, and decorative interiors. Creative builders get more shapes, while Survival players have a straightforward crafting path from a familiar material.
How to craft Packed Ice Bricks
The recipe is simple: place four Packed Ice blocks in a 2 × 2 crafting arrangement to make the new brick block. Mojang also lists slabs, stairs, walls, and Chiseled Packed Ice as part of the set. These decorative variants can be made with a Stonecutter, giving builders flexibility when shaping roofs, archways, parapets, and other details.
For a practical build, start with the regular bricks as walls and floors, break up flat surfaces with chiseled accents, and use stairs and slabs to avoid an overly boxy outline. Walls can frame windows and paths without requiring full blocks everywhere. A compact watchtower or frozen entrance hall is a good first project because it lets you compare all five visible shapes in one structure.
One detail worth noting is the interaction with Sulfur Cubes. Mojang's Java notes assign Packed Ice Bricks and Chiseled Packed Ice to the Fast Sliding Sulfur Cube archetype. That makes these blocks interesting beyond decoration when experimenting with the newer sulfur mechanics. The exact results of a complicated machine should still be tested in the version you plan to use rather than assumed from a screenshot.
In the parallel Bedrock Preview 26.70.21 notes, Mojang explicitly describes the new bricks as decorative, non-melting, and best mined with a pickaxe. Java and Bedrock receive related frozen building features, but individual mechanics and known issues can still differ while these builds are in testing.
The Frostbite advancement: What Goes Around Comes Around
Snapshot 5 introduces the Adventure advancement What Goes Around Comes Around. To earn it, a player must kill a Frostbite using an Ice Ball. That is a neat reversal: the winter area's hostile creature can be defeated with the same type of icy projectile players associate with the new freezing encounters.
This is not the first appearance of the Frostbite. The frozen zombie variant was already part of the October 6 Java testing wave, alongside Ice Caves and their distinct hazards. The new advancement gives players a specific goal to pursue once they have learned to navigate the biome and handle its enemies.
If you are planning an achievement-focused play session, treat the Ice Ball as the final blow requirement. Do not assume that simply hitting a Frostbite once with an Ice Ball and finishing it with a sword will unlock the advancement. Test the encounter in a throwaway snapshot world until you understand projectile timing and damage. The official notes specify the kill condition, not a guaranteed one-shot method.
For more background about the frozen biome itself, see our existing Minecraft 26.4 Ice Caves survival guide. This article concentrates on the newer Snapshot 5 changes rather than repeating the entire cave guide.
Ice blocks can now make ambient sounds
Mojang has added a conditional ambient sound for regular Ice. This is not an always-on audio effect for every frozen block. According to the Java changelog, an Ice block has a chance to produce the sound when surrounded by at least eight Ice blocks horizontally, with Air above and Water below. The stated arrangement makes frozen waterways and layered ice environments especially interesting for atmosphere.
Try building a quiet lake under a roof of ice, or visit a winter cave with suitable water and ice geometry. The new audio is a small touch, but environmental sounds make locations easier to remember than another large room filled with blue blocks. Sound changes can also matter to resource-pack authors, who should check updated event names rather than assume older sound substitutions will continue behaving identically.
New experimental Windows graphics option
Players on Windows get a new video option labeled Prefer DXGI Present. It attempts to use DirectX for the final display presentation and may improve certain input-method editor interactions, Variable Refresh Rate behavior, or the speed of switching away from fullscreen Minecraft. Mojang marks it experimental, says not every graphics setup supports it, and leaves it disabled by default.
Do not interpret the setting as a universal FPS boost, a requirement for Vulkan, or proof that every laptop will run Minecraft more smoothly. If you choose to test it, change one setting at a time, compare the same scene, and revert to the default if you notice glitches. The community-maintained snapshot documentation also warns about reported Vulkan window-resizing crashes and windowed rendering problems. Those reports are a reminder to avoid this experimental version for an important recording session or irreplaceable save.
What changes for Minecraft server owners?
This snapshot matters to technical players because it changes how the Java login protocol applies encryption and compression. Rather than switching settings immediately, the server sends specific connection-option packets and the client acknowledges them before subsequent packets use those options. Mojang says the previous timing could produce malformed packets. The new handshake is intended to make the transition explicit.
That does not automatically mean every server proxy or plugin is broken. It does mean operators who develop custom protocol bridges, packet inspection tools, compatibility layers, or proxy software should review the changelog and test with a matching snapshot client. A stable-release plugin claiming compatibility with a different protocol is not automatically validated for Snapshot 5.
The data pack version is 125.0 and the resource pack version is 100.2. Resource-pack makers also get new textures for Packed Ice Bricks and Chiseled Packed Ice. For custom world generation, the snapshot adjusts certain ore replacement behavior and the configurable density-function upscaling system. These are genuine technical changes; worlds and packs using advanced customization deserve targeted regression tests.
If your Minecraft community runs a public multiplayer world, test this release in a disposable environment rather than moving production. Verify startup, player joins, proxy forwarding, permissions, resource packs and important datapacks. You can browse production communities through our Minecraft server list, but a server appearing in a directory does not imply that it supports an experimental snapshot.
Other fixes worth knowing about
Mojang lists fixes in several different areas. The dedicated server's compression setup received a race-condition fix (MC-308621). The snapshot addresses crashes related to music-disc tooltips and malformed jukebox playlist positions, as well as issues with chests supplying discs to jukeboxes. Ice Caves receive world-generation fixes involving ruined portals and biome tags, while Frostbite spawning and multiple mob-effect immunity behaviors have also been corrected.
Some of these fixes are easy to notice while playing, such as a jukebox working as expected or a painting no longer breaking outside the world border. Others, such as pack data and compression changes, are more relevant to developers. It is useful to distinguish fixes from new gameplay content: a repaired spawning rule is not a new mob, and a new pack format is not a separate downloadable expansion.
Java Snapshot 5 versus Bedrock Preview 26.70.21
Both testing tracks were updated on October 20, 2026 with the winter-building theme, but their identifiers and individual change lists differ. Java's build is named 26.4 Snapshot 5; Bedrock's contemporary test build is Preview/Beta 26.70.21. Mojang's Bedrock notes include Ice Ball damage adjustments, freezing-related fixes, and changes to Ice Cave crevasses and brittle ice in addition to the new brick block family.
The Bedrock preview also describes an early Music Features Add-On, with a Disc Press and Pocket Jukebox, as a separate test feature that needs to be enabled for a world and does not yet work with Realms. Do not assume that this add-on is a built-in Java Snapshot 5 feature. Keeping each edition's changelog separate avoids confusing players who only see one of the two testing environments.
How to install Snapshot 5 without risking your world
Open the official Minecraft Launcher, go to Installations, enable Snapshots, and create or select an installation for 26.4 Snapshot 5. Mojang's own announcement warns that snapshots may corrupt worlds. Make a manual backup before opening anything valuable, and preferably configure a separate game directory so your stable saves, settings, and experimental saves do not share the same files.
For multiplayer testing, use the snapshot server download linked from Mojang's changelog, keep it separate from your production server, and expect plugin or datapack incompatibilities. Start with a clean world and a small set of test clients. Record any reproducible problems and report them through the official Minecraft issue tracker. Testing builds exist partly so players and creators can find problems before the stable drop is released.
Our verdict: small additions with useful consequences
Snapshot 5 is not a giant new biome reveal, but it offers something concrete to build with and test. Packed Ice Bricks make the winter theme more versatile, the Frostbite advancement gives explorers a new combat objective, and the ice sounds reward attention to environmental detail. The server login changes are arguably the most important news for developers maintaining tools that sit between a client and server.
If you enjoy building, this is a promising preview. If you administer a busy survival server, the sensible decision is to evaluate it separately and wait for stable support before migrating players. Minecraft 26.4 is still in development, so details may change before the final game drop. For authoritative changes, consult the official Java Snapshot 5 notes and Bedrock Preview 26.70.21 notes.
