Minecraft 26.4 Snapshot 7 Explained: Calcite Blocks, the Flurry Music Disc and the Winter Drop's Final Content

Mojang released Minecraft 26.4 Snapshot 7 on November 3, 2026, and the studio is calling it the final batch of new gameplay content before the Winter Drop ships. Snapshot 7 adds a full calcite building block set, a new music disc called "Flurry," and the first real pass at keyboard and screen-reader support for gameplay screens like the crafting table. It also tweaks how the new Freezing effect interacts with fire and leather armor, and quietly changes which graphics API the game defaults to on startup.

Here is everything confirmed in Snapshot 7, plus where it fits into the wider Winter Drop (officially tracked by Mojang as Drop 4 of 2026) that has been rolling out in weekly snapshots since late September.

1. Calcite joins the building block roster

The headline addition is Calcite, Polished Calcite, and Polished Calcite Bricks, each with pillar, slab, stair, and wall variants where applicable. This gives builders a smooth, pale-grey stone family that sits alongside existing blocks like quartz and diorite, but with its own distinct pillar texture.

How to craft it

• Polished Calcite is made from a 2x2 crafting grid of Calcite blocks.
• Polished Calcite Bricks are made from a 2x2 grid of Polished Calcite.
• Most of the pillar, stair, and slab variants can also be cut directly from the base block using a Stonecutter, which saves a trip back to the crafting table.

Mechanically, Mojang has placed calcite and both of its polished forms into a new "Slow Bouncy" Sulfur Cube archetype — the same system introduced with the Chaos Cubed update earlier this year for how certain blocks interact with Sulfur Cubes. Builders working with the Sulfur Cube mechanics from the Chaos Cubed update will want to keep this in mind if they're mixing calcite into redstone or bounce-pad contraptions.

2. A new music disc: "Flurry"

Snapshot 7 adds a thirteenth music disc, "Flurry," composed by Hyper Potions. It generates inside the basement chests of Igloos, so players will need to dig down through an igloo's hidden trapdoor and ladder to find one. In a Jukebox, Flurry gives a comparator output signal strength of 7, which matters for anyone building redstone contraptions keyed to specific disc signals.

Mojang's own snapshot notes frame it as a quiet, wintry counterpart to discs like "Pigstep" and "Otherside" — a small addition, but one that gives the Winter Drop its own dedicated piece of music alongside the new blocks and mobs.

3. Freezing, fire, and leather armor now interact

The Freezing effect — introduced earlier in the Winter Drop testing cycle alongside the Frostbite mob's Ice Balls — got two balance changes in Snapshot 7:

• Being on fire now counteracts Freezing, the same way leather armor already did. If you're burning, you won't also be freezing.
• Wearing any piece of leather armor now stops Zombies and Skeletons in cold biomes from converting into Frostbites or Strays. Previously this only affected the Freezing status effect itself.

Mojang also expanded where Strays can spawn naturally, adding Deep Frozen Ocean, Frozen Ocean, Frozen Peaks, Frozen River, Jagged Peaks, and Snowy Slopes to the list. That spreads the undead archer out of just icy underground areas and into the cold biomes above ground.

4. The first real push on gameplay-screen accessibility

The most significant systems change in this snapshot isn't a block or a mob — it's accessibility. Mojang describes this as a "first step" toward making gameplay screens like the Crafting Table fully navigable without a mouse:

• Keyboard focus now works on these screens: Tab moves between slot groups, and arrow keys move within a group.
• Enter or Space acts as a left-click on the focused slot; Ctrl+Enter/Space right-clicks; Shift+Enter/Space shift-clicks.
• Double-pressing a slot's select key collects matching items into it, and holding an arrow key with Enter/Space spreads a carried stack across multiple slots.
• Hotbar number keys and the Drop key now act on whichever slot is focused.
• The narrator reads out slots, their contents, and their position for screen-reader users.

Mojang is upfront that this doesn't cover everything yet — the Creative Inventory and the Recipe Book aren't supported in this pass. But as a first step for a game with this much UI surface area, it's a meaningful one, and it's paired with smaller UI polish: hovered list entries (like friends or worlds) now get a grey outline, Tab both focuses and enables editing in text boxes, and the mouse cursor hides itself while you're navigating with the keyboard.

5. A graphics API change worth knowing about

If your game has felt different since updating, this may be why: the "Default" graphics API setting now randomly picks OpenGL or Vulkan each time the game starts. Mojang's own snapshot notes explain that because they've been defaulting internally to Vulkan throughout this testing series, OpenGL has gotten comparatively little testing recently — and they plan to walk this random behavior back in a future snapshot. If you hit graphical glitches, check which API you're actually running under in the video settings before assuming it's a bug with the new content itself.

Alongside that, this snapshot closes out 47 separate bug reports, covering everything from inventory drag-and-drop issues and stonecutter UI misalignment to Vulkan memory leaks and experience orbs failing to fall correctly after a player disconnects. The full list, with tracker numbers, is on Mojang's own bug tracker linked below.

6. Where this fits in the Winter Drop so far

Snapshot 7 is the last of five content snapshots Mojang has shipped since the Winter Drop's biome and mob reveal. The Ice Caves were first shown off at Minecraft Live 2026, and the weekly snapshots have layered on features since:

• Late September/early October: Ice Caves generation, the Frostbite zombie variant, Ice Crystals, and Icicles.
• October 13: Chest-fed Jukebox playlists, brittle ice that cracks under weight, and crevasses.
• October 20: Ambient ice sounds and Packed Ice Bricks.
• October 27: Sulfur Cubes that can freeze water, plus Snow Bricks — the update covered in the site's Snapshot 5 breakdown.
• November 3 (this snapshot): Calcite blocks, the Flurry music disc, and the accessibility pass above.

Mojang hasn't confirmed an official name or release date for the finished Winter Drop, and anything circulating online beyond what's listed here — including specific release-week dates — is speculation, not confirmed by Mojang. What is confirmed is that Snapshot 7 is described as the last snapshot adding new gameplay content, so from here testing should shift toward stability and bug fixing ahead of the full release.

7. How to try it yourself

You don't need to wait for the full release to test any of this:

• Java Edition: Open the Minecraft Launcher, go to Installations, and create a new installation using the latest snapshot version. Snapshots are separate from your main save folder by default, but back up any world you care about before loading it in a snapshot anyway.
• Bedrock Edition: Opt into the Bedrock Preview or Beta channel, available through the Microsoft Store on Windows and Xbox, and through the Google Play and Apple TestFlight beta programs on mobile. Realms Plus and Realms support preview access too.

Mojang is actively collecting bug reports and feedback through the official bug tracker and feedback site linked below — both are the right place to flag issues, rather than social media.

Quick tips recap

• Calcite, Polished Calcite, and Polished Calcite Bricks are new in Snapshot 7 — craft polished variants in a 2x2 grid, or cut most shapes with a Stonecutter.
• Find the new "Flurry" music disc in Igloo basement chests; it has a comparator output of 7.
• Being on fire now cancels Freezing, and any leather armor piece now blocks Frostbite/Stray conversion, not just the Freezing status.
• Strays can now spawn in six additional cold biomes above ground, not just underground ice areas.
• If the game looks different after updating, check whether you're running OpenGL or Vulkan — the "Default" setting now picks one at random each launch.
• Crafting-table-style screens now support keyboard and narrator navigation as a first accessibility pass; the Creative Inventory and Recipe Book aren't covered yet.
