Mojang Studios rolled out Minecraft: Java Edition 26.4 Snapshot 5 on October 20, 2026, bringing in fresh ice-themed building blocks, an achievement tied to Frostbites, ambient ice sounds alongside a variety of technical modifications and bug fixes. Note that this is a testing snapshot rather than a stable release.
The most visually prominent addition is Packed Ice Bricks, serving as a new decorative block family suited for frozen constructions. Players can craft Packed Ice Bricks by arranging Packed Ice in a 2×2 pattern, and subsequently utilize a Stonecutter to produce Slabs, Stairs, Walls, and Chiseled Packed Ice.
Advancement and Mob Changes
Snapshot 5 includes a fresh Adventure advancement titled ‘What Goes Around Comes Around,’ which users earn by defeating a Frostbite with an Ice Ball. These variants grant builders far greater flexibility with Packed Ice, making it possible to construct walls, staircases, floors, and intricate ice designs instead of being restricted to standard full blocks. Additionally, Mojang specifies that Packed Ice Bricks and Chiseled Packed Ice fall under the Fast Sliding Sulfur Cube archetype.
Mob interactions with specific blocks have also been adjusted by Mojang. Within Adventure mode, mobs can now destroy Decorated Pots, Chorus Flowers, and Speleothem blocks via projectiles, provided the ‘mob_griefing’ gamerule isn’t turned off.
Furthermore, a bug fix ensures that zombies, husks, drowned, strays, and frostbites are now properly impacted by Poison and Regeneration. The update additionally resolves a problem where mobs possessing multiple entity-type tags regarding effect immunity would only acknowledge one of those tags.
Ice Sounds and World Generation
Standard Ice blocks now possess the capability to emit ambient audio. This happens when an Ice block is completely enclosed by a minimum of eight Ice blocks across all horizontal angles, features one Air block above it, and sits directly on top of one Water block—though even under these conditions, it only has a probability of generating sound.
Regarding exploration, the snapshot addresses multiple world-generation glitches. Mojang has additionally modified the ore and scattered_ore world-generation mechanics, ensuring that blocks discarded following air exposure will no longer drop through to subsequent replacement rules. Meanwhile, the interpolated density function has been rebranded to upscale, bringing fresh configuration choices for sampling and upscaling terrain-generation algorithms.
Graphics and Technical Changes
The update delivers a brand-new Windows-exclusive video option called ‘Prefer DXGI Present.’ This feature attempts to leverage DirectX for game presentation, though it remains experimental, disabled by default, and unsupported across all hardware configurations.
According to Mojang, when functioning correctly, ‘Players may see improvements in IME support, Variable Refresh Rate support and faster alt-tabbing in fullscreen mode. Since it is experimental, players should not assume it will improve performance on every Windows PC.’
Technical users should take note that the Data Pack version is now raised to 125.0, while the Resource Pack version advances to 100.2. The login procedure has also been modified: servers must explicitly enforce encryption and compression via connection-option packets, requiring clients to acknowledge those parameters prior to sending any subsequent packets. Moreover, data-pack creators will discover that the sound field in Minecraft: Consumable is now entirely optional.

Major Bug Fixes
Over 30 reported issues have been resolved in this snapshot. Key corrections consist of:
-
Blocks shattered by flowing fluids now generate appropriate particles and breaking noises.
-
Creakings stop attempting to attack players once they transition into Creative mode.
-
Paintings no longer rupture outside the boundaries of the world border.
-
Jukebox crashes stemming from hidden music-disc tooltips and negative playlist_position values have been patched.
-
Mobs are restricted from spawning on top of honey blocks.
-
Pointed dripstone positioned underneath flowing lava correctly drips lava instead of water.
How to Test it Safely
These testing snapshots are exclusively available for Minecraft: Java Edition. To set one up, launch the Minecraft Launcher, navigate to the Installations tab, and turn on snapshots.
Mojang cautions that preview builds carry the risk of corrupting saved worlds. Users ought to back up their saves or launch the snapshot inside a dedicated folder separated from their primary worlds before trying it out.
What it Means for Players
Packed Ice Bricks stand out as the primary highlight for builders, providing a functional new medium for winter-inspired designs. Explorers will benefit from corrected village, ruined-portal, and ice-cave generation, whereas technical creators receive fresh tags, revised data-pack formats, and an experimental DirectX-oriented graphics setting. Just like every snapshot, it should be approached as a preview rather than a finished patch.
