Minecraft 26.3 Update: Dappled Forest, Wool Stairs & Third Drop 2026

Minecraft 26.3 has entered public snapshots. Mojang calls it the Third Drop 2026, and the first two snapshots (26.3 Snapshot 1 on June 23, 26.3 Snapshot 2 on June 30) already give a very clear picture of what the update is about: a warm, autumnal forest biome called the Dappled Forest, a brand new Poplar wood set, long-requested Wool Stairs and Slabs, Abandoned Camps that spawn across many biomes, and a full graphics overhaul on Java. Below is what you actually need to know as a server owner.

Release Timeline

• Snapshot 1: released June 23, 2026 (biome, wood set, structures)
• Snapshot 2: released June 30, 2026 (Order-Independent Transparency, block transformer component, world-gen tweaks)
• Full 1.0 (26.3): targeted for Q3 2026. Mojang has not committed to a firm date yet, but the snapshot cadence is on track for a late-summer or early-autumn release.

The snapshots are opt-in through the Java launcher's Latest Snapshot channel. Your production server should stay on the current 26.2 stable branch for now. Snapshot worlds are not compatible with stable and Mojang explicitly warns that anything loaded into 26.3 cannot be brought back to 26.2, so run a scratch server if you want to try it.

The Dappled Forest Biome

The star of Snapshot 1 is the Dappled Forest, an autumn-toned forest that generates near cold biomes. It is instantly recognisable: rolling terrain of red, orange, and yellow leaves on tall poplar trees, red shrubs on the forest floor, brown mushrooms clustered around the roots, and a new Shelf Mushroom growing directly on poplar trunks and fallen logs. Shelf Mushrooms are bouncy when you land on them, and they can be dropped into a stew for a new food recipe.

The Poplar wood set is a full family: logs, planks, stairs, slabs, doors, fences, buttons, pressure plates, signs, hanging signs, saplings, and three leaf variants (red, orange, yellow). Wandering traders now sell poplar saplings and shelf mushrooms as new stock, which means players can bring them back to your server's spawn without having to travel to the biome first, useful for map-locked or old worlds where the Dappled Forest is not going to appear naturally without a chunk migration.

Wool Stairs and Slabs

This is the community-request corner of the update. After more than a decade of demand, wool finally gets stairs and slabs. All 16 wool colours are supported, and every variant keeps the acoustic property of standard wool: they dampen sculk shrieker vibrations and block sound-based sensors the same way full wool blocks do.

For build servers and creative worlds, this is a big deal. Two flag-planting notes for admins:

• Carpets can no longer be crafted as of Snapshot 1. Snapshot 2 reverted that regression, so by 26.3 stable, carpets and the new wool stairs and slabs will coexist. Do not warn your creative players about a permanent carpet removal, it was a temporary snapshot bug.
• Existing skulk-based redstone farms that use wool as a sound damper still work. The stair and slab variants extend those builds rather than break them.

Abandoned Camps

Abandoned Camps are a new structure that generates across many biomes, each with a themed variant to match the surroundings. Every camp contains loot chests and barrels with a mix of common utility items and rare pulls. Because they spawn across biomes rather than being locked to one, they will appear naturally in fresh chunks all over your world, which is a genuine reason to trigger new chunk generation on long-running servers when 26.3 goes stable.

The loot tables are still being tuned, so do not benchmark drop rates against Snapshot 1 or 2. Wait for the release candidate before writing farm guides for your community.

Snapshot 2: Order-Independent Transparency and the Block Transformer Component

Snapshot 2, released June 30, 2026, is the technical side of the drop. Two things matter:

Order-Independent Transparency (OIT). Java's translucent rendering has been overhauled. The old "Improved Transparency" video setting is gone and replaced by an OIT algorithm that resolves layered translucency correctly, no more black stained-glass artefacts when two coloured panes are stacked, no more nether portal flicker through water. Six new shader files and a large batch of modified core shaders back this change. Resource packs and shaders that touch translucent rendering will need to be updated for 26.3, worth flagging to your community if you run a pack-heavy server.

Block Transformer Component. This is a new data-driven item component that lets axes, hoes, and shovels transform blocks with customisable sounds, particles, and loot drops. Datapack authors on your server can now define a "strip this custom log," "till this custom soil," or "path this custom grass" behaviour for their own blocks without touching mixin territory. It is one of the cleanest server-side extension surfaces added in a long time.

Snapshot 2 also adds:

• A height_range block predicate, useful for datapack condition checks
• An overlay feature type and a projected_random_patchy_square feature for world-gen datapacks
• Expanded customisation for carvers and pillar features in world-gen JSON

Combat and mob tweaks in Snapshot 2 worth mentioning:

• Drowned holding tridents now switch to melee within 3 blocks, matching Bedrock. Trident farms will need re-tuning.
• Shield-raising now takes precedence over hoe or shovel tilling when both are equipped. Fewer accidental farmland placements in PvP.
• Persistent mobs' random ambient behaviours deactivate when no player is nearby, a quiet server-tick optimisation that helps large farms.

What This Means for Your Server

• Do not migrate your production server to snapshots. 26.3 worlds are one-way, and Snapshot 1 and 2 are pre-release quality.
• Stand up a scratch server on 26.3 Snapshot 2 if you want to preview datapacks, resource packs, or shaders against OIT and the block transformer component. A separate Pterodactyl instance on your DoomHosting panel is the cleanest way to do this.
• Back up your world before the stable 26.3 upgrade. Once the world touches 26.3, it cannot be opened by 26.2 clients or servers. Take a full FTP snapshot to your local machine first.
• Warn your resource-pack and shader authors that translucent rendering is going to change under them. OIT-aware packs are worth updating well in advance of the stable release.
• Expect a player-count spike on the day 26.3 goes stable. Autumn biome, wool stairs, and abandoned camps will all pull returning players. Scale your RAM plan for the launch weekend, and pre-warm your simulation-distance and view-distance settings for the new chunk generation load.
• Set expectations on new terrain. The Dappled Forest and Abandoned Camps will only generate in newly loaded chunks. Long-running maps will need chunk migration tools if you want your players to see the new content without travelling thousands of blocks out.

Verdict

This is the strongest game drop of 2026 so far. The Dappled Forest is a rare "purely aesthetic" biome that actually looks distinct from what the game already has, Wool Stairs and Slabs answer a decade-old community request without breaking existing builds, Abandoned Camps drop natural exploration content into biomes that have felt empty since the aquatic update, and OIT is a genuine engine-level improvement that servers will feel through better resource-pack behaviour. The block transformer component is a very quiet but very important server-side extension surface, expect the datapack scene to spend the next two months building around it.

If you run a build server, a survival community, or an adventure map, 26.3 is worth planning around now, not on release day.
