Minecraft 26.3 Snapshot 10: What's New
Contents
26.3 Snapshot 10, a test build of Minecraft: Java Edition, came out on 25 August 2026. It’s a snapshot, not a release: everything in it is Mojang showing work in progress, and any change here can be dropped before the final version or land in a different shape.
Two official sources confirm the date — Mojang’s version manifest, which is what the launcher uses to list builds, and the changelog for the version itself. Here’s exactly what changed in this build.
First, the format: a snapshot isn’t an update
A snapshot is an in-between build for testing. It doesn’t replace your regular copy of the game, and it isn’t what Mojang will eventually ship as the finished update. A feature added in a snapshot can vanish in the next one; a behaviour change can get reverted — and in this very build, that’s exactly what happened (more on that below).
The practical takeaway is simple: keep worlds you load in a snapshot separate from your main ones. For how snapshots work in general, how to enable them, and what to expect, see our guide to Minecraft snapshots.
One more thing worth being clear on: everything below applies to Java Edition. The sources we drew these facts from say nothing about other editions — if you’re unsure what actually separates the branches of the game, there’s a separate piece on Java vs. Bedrock.
A new main menu panorama
The most visible change is one you’ll notice before you even load a world. The main menu has a new panorama — the scene rotating behind the buttons.
It shows the Dappled Forest biome with an Abandoned Camp structure in it.
Here’s a caveat right away. The changelog says exactly what you just read: the panorama shows this biome and this structure. What Dappled Forest actually is, how it generates, what blocks or mobs live there — none of that is stated. We’re not filling that in from guesswork. The panorama is a menu image, not a description of in-game content.
Realms: an intro screen
Realms now has an intro screen listing the service’s key features. You can open it via the “Add Realm” button, and if you’re eligible for a trial period, it appears automatically.
This is aimed at people encountering Realms for the first time and not sure what they’d be paying for. For what the service actually is and how billing works, see our separate piece on Realms pricing and features.
Explorer maps got renamed
Five maps got new names, purely to bring them under one consistent pattern. This is a plain rename — the changelog doesn’t mention any change to how the maps function.
| Was | Now |
|---|---|
| Ocean Monument Explore Map | Ocean Monument Map |
| Swamp Hut Explorer Map | Swamp Hut Map |
| Woodland Mansion Explorer Map | Woodland Mansion Map |
| Jungle Pyramid Explorer Map | Jungle Pyramid Map |
| Trial Chambers Explorer Map | Buried Trial Chambers Map |
Notice the last row: it’s not just “Explorer” dropped — “Buried” was added too. It’s the only one of the five names that changed by more than a simple trim.
If you rely on data packs, macros, or third-party tools that reference items by name, this is exactly the kind of change that quietly breaks other people’s setups. Worth checking your own.
Drowned changes rolled back
Mojang reverted behaviour and animation changes to Drowned mobs — changes it had made earlier in this same development cycle.
This is precisely the situation the caveat at the top of this article is warning about. The change lived through several snapshots and then disappeared. If you’d already rebuilt a farm or a tactic around it, that work is now outdated again.
Exactly what the behaviour was rolled back to, and whether it returns later, isn’t stated in the changelog.
Smaller changes
The rest of what’s in this build:
- Adventure mode icon. In the gamemode switcher, it’s now the Buried Treasure Map icon.
- The /compute command. A new command that evaluates
minecraft:number_providerin various contexts. It’s a tool for data pack authors, not for regular play. - Pack versions. The Data Pack version moved up to 118.0, and the Resource Pack version to 97.0. In practice, this means the game in this build may reject older packs that haven’t had their manifest updated.
- Subtitles. Changed for accessibility: a subtitle now points to the most recent sound within hearing range. For accessibility settings more broadly, see our guide on controls and accessibility.
- Performance. A separate performance improvement is claimed for structure searches in the world.
Worth being honest about that last point: there are no figures in the changelog — no percentages, no milliseconds, no chunk counts. Only the fact of an improvement is claimed, and that’s exactly what we’re passing on.
What we’re not claiming
The most useful part of any snapshot write-up is the list of what the sources don’t say.
- A release date for the full 26.3 update. None is given. Any date you see elsewhere doesn’t come from the official changelog.
- A description of the Dappled Forest biome. All that’s said is that it appears on the new menu panorama. Everything else about it is outside our sources.
- What the Abandoned Camp actually is in-game. Same story: it’s a structure on the panorama, and the changelog says nothing more.
- Which of these changes will survive to release. That’s the nature of a snapshot. The Drowned rollback in this very build is a live example.
- Any changes to other editions of the game. The sources cover Java Edition.
- Why Mojang rolled back the Drowned changes or why the maps were renamed the way they were. No explanation is given in the changelog.
What to actually do about it
If you’re playing on a stable release, there’s nothing to do. A snapshot doesn’t install itself — you have to deliberately enable it in the launcher.
If you make data packs or resource packs, this snapshot concerns you the most: the new pack version numbers, the renamed items, and the new /compute command all touch your workflow directly.
If you just want to see the new panorama, open the main menu — it’s the first thing you’ll see. And keep a separate copy of your worlds before loading them into a test build.

In short
26.3 Snapshot 10 came out on 25 August 2026, bringing a new main menu panorama featuring the Dappled Forest biome, a Realms intro screen, renamed explorer maps, the /compute command, and a rollback of the Drowned changes. It’s a Java Edition test build — none of these changes are guaranteed to make it into the final release.
Frequently asked questions
When did 26.3 Snapshot 10 come out?
On 25 August 2026. The date is confirmed by Mojang's official version manifest and the changelog.
Is this a full update already?
No. It's a snapshot — a test build of Java Edition. Anything in it can be dropped before the final release, or ship looking different.
When does the full 26.3 update come out?
There's no date. Mojang hasn't named one in any source we used, so we're not giving one.
What changed with the explorer maps?
Five maps were renamed for a consistent naming pattern — the word "Explorer"/"Explore" was dropped from their names, and the trial chambers map became the Buried Trial Chambers Map.
Do these changes apply to Bedrock Edition?
The sources we rely on cover Java Edition only. They say nothing about other editions, so we're not extending these changes to them.
What does the new /compute command do?
It evaluates a minecraft:number_provider in various contexts. It's a tool for data pack creators.
