Minecraft: Java Edition 26.2 Released

26.2 is the official release of the Chaos Cube update, as well as a minor update for the Java Edition, released on June 16, 2026[1]. This update introduces Sulfur Caves, Sulfur, Cinnabar, and Sulfurbots, along with several bug fixes.

New Content

Blocks

Sulfur

• Generates naturally in Sulfur Caves.
• Available in stair, slab, and wall variants.
• Available in polished, brick, and chiseled variants.
• The appropriate tool for mining is a pickaxe.

Polished Sulfur

• Polished variant of Sulfur.
• Available in stair, slab, and wall variants.

Sulfur Bricks

• Brick variant of Sulfur.
• Available in stair, slab, and wall variants.

Chiseled Sulfur

• Chiseled variant of Sulfur.

Volatile Sulfur

• Generates naturally in sulfur pools and sulfur springs within Sulfur Caves.
• Generates bubbles in the 4 water source blocks above it.
  • If there are fewer than 4 water source blocks above, the bubbles reach the surface and produce yellow particles within a 3-block radius; players entering this area receive the Nausea effect.
• Can be crafted using 9 Sulfur.
• When placed beneath 1-4 blocks of water, waterlogged scaffolding, or waterlogged blocks without collision volume—provided the block above the water is air or a block without collision volume—the water surface forms a geyser. When erupting, geysers behave similarly to bubble columns, pushing entities above them upward.
  • When placed above Magma Blocks, geysers erupt periodically; the duration of eruption and dormancy is determined by the block's position.
  • When placed above Lava Sources, geysers erupt continuously, though the sound is slightly quieter than when placed above Magma Blocks.

Cinnabar

• Generates naturally in Sulfur Caves.
• Available in stair, slab, and wall variants.
• Available in polished, brick, and chiseled variants.
• The appropriate tool for mining is a pickaxe.

Polished Cinnabar

• Polished variant of Cinnabar.
• Available in stair, slab, and wall variants.

Cinnabar Bricks

• Brick variant of Cinnabar.
• Available in stair, slab, and wall variants.

Chiseled Cinnabar

• Chiseled variant of Cinnabar.

Sulfur Spikes

• A block similar to Pointed Dripstone.
• Generates naturally on Sulfur in the Sulfur Cave biome.
• Placed as a stalactite when attached to the bottom of a block, and as a stalagmite when placed on the top surface.
• Under specific conditions, stalactites grow slowly if there is Sulfur above them, causing stalagmites to grow slowly on the block below; stalactites can grow up to two blocks high.
• Adjacent stalagmite tips and stalactite tips connect to form a stone column, unless placed while holding ⇧ Shift.
• Stalagmites are destroyed if they lack a supporting block underneath.
• Unlike Pointed Dripstone, falling onto the tip of a stalagmite does not increase fall damage.
• Stalactites become falling blocks if they lack a supporting block above.
• Falling stalactites deal significant damage to entities.
• Stalactites do not drip water or lava like Pointed Dripstone.
• Can be destroyed by being hit with a trident.

Items

Sulfurbot Bucket

• Obtained by using a bucket on a medium-sized Sulfurbot.
• Releases the Sulfurbot when used on a block.

Music Disc

• Added a new music disc, "Bounce".
  • Composed by fingerspit.
  • Can be found in minecarts inside abandoned mineshafts within Sulfur Caves.
  • Rarity is "Uncommon".
  • Outputs a redstone signal strength of 8 when used with a Redstone Comparator.

Spawn Egg

• Added a Sulfurbot spawn egg.

Mobs

Sulfurbot

• A new friendly mob.
• Generates naturally in Sulfur Caves.
• When a player interacts with it while holding a block, it absorbs the block and disables its own AI.
• When a player interacts with a Sulfurbot containing a block while holding shears, the block is sheared off and the mob's AI is re-enabled.
• Follows players holding blocks it can absorb.
• Searches for nearby block item entities and moves toward them to absorb them.
• Splits into two small Sulfurbots upon death.
• Small Sulfurbots can be attracted and fed with Slimeballs to grow into medium-sized Sulfurbots.
• When containing a block, it acts as an object that can be interacted with by players through attacking or pushing, and it does not take fall damage or damage from players.
• Sulfurbots containing blocks have 13 different prototypes with varying physical properties.
• Medium-sized Sulfurbots can be picked up with a bucket.
• Dispensers can be used to make them absorb or swap blocks, and shears can be used to remove the contained block.
• Dispensers can spawn a Sulfurbot using a Sulfurbot Bucket.

World Generation

Sulfur Caves

• A new cave biome.
• Generates underground or on the surface in non-river biomes.
• Less common beneath oceans, hills, or mountains.
• Composed of Sulfur and Cinnabar.
• Generates sulfur pools containing small amounts of Volatile Sulfur.
• Generates clusters of Sulfur Spikes.
• Sulfurbots and Cave Spiders spawn here.

Sulfur Springs

Sulfurbot Prototypes

• Prototypes are distinguished by speed after being hit, bounciness when colliding with blocks or collidable entities, ground friction, air resistance, and buoyancy in water.
• Each prototype has unique hit and push sound effects.
• Current prototypes include:
  • Normal: Medium speed, medium bounciness, medium ground friction, and low air resistance.
    • Has buoyancy.
    • Used when absorbing earth-type blocks.
  • Bouncy: High speed, high bounciness, medium ground friction, and low air resistance.
    • Has buoyancy.
    • Used when absorbing wood-type blocks.
  • Slow Bouncy: Low speed, high bounciness, medium ground friction, and medium air resistance.
    • Used when absorbing stone and mineral-type blocks.
  • Slow Sliding: Low speed, low bounciness, medium ground friction, and medium air resistance.
    • Used when absorbing metal blocks.
  • Fast Sliding: High speed, low bounciness, medium ground friction, and low air resistance.

    • Absorbed TNT can be activated by redstone, fire, or nearby explosions.
    • When activated by fire or redstone, the absorbed TNT explodes after 6 seconds.
    • When activated by an explosion, the absorbed TNT explodes after 0.75-3 seconds.
    • Activated TNT Sulfurbots cannot be picked up with a bucket.
    • Activated TNT Sulfurbots are immune to most damage.
    • Activated TNT blocks cannot be removed with shears.
    • Does not split into small Sulfurbots upon explosion.
  • Hot: Same properties as the Normal prototype, but damages entities upon contact like a Magma Block.
    • Used when absorbing Magma Blocks.

Advancements

• Added 1 new advancement:
  • Broken
    • Obtained by having a Sulfurbot absorb TNT.

Command Format

/unpublish

• If currently an integrated server, cancels opening the world to LAN.

General

Splashes

• Added the following splashes:
  • Now on Vulkan 1.2!
  • Music by fingerspit!

Languages

• Added Chuvash, Swiss French, Gallo, Uzbek, and Võro.

Options

• Added a "Graphics API" option in Video Settings.
  • Options include "Default", "Prefer Vulkan (Experimental)", and "Prefer OpenGL".
  • Currently, "Default" is equivalent to "Prefer OpenGL", which may change in the future.
  • Mojang recommends "Default" for all users, except when troubleshooting issues.
  • "Prefer Vulkan (Experimental)": Attempts to use Vulkan rendering, falling back to OpenGL if unavailable.
  • "Prefer OpenGL": Attempts to use OpenGL rendering, falling back to Vulkan if unavailable.

Graphics API

• The game can now use Vulkan for rendering.
• Some older hardware and drivers do not support Vulkan, in which case it falls back to OpenGL.
• System requirements for Vulkan rendering are Vulkan 1.2 with support for dynamic rendering and push descriptors, though this may change.
• Vulkan rendering is currently experimental; performance and stability may be poor.
• When using Vulkan, the game prioritizes dedicated GPUs over integrated ones, unlike when using OpenGL.
• The current rendering Graphics API can be viewed in the debug overlay under "system_specs".
• On macOS, the game uses MoltenVK to translate Vulkan to Metal.

Friends List

• Added a Friends List, accessible via the "Friends" button on the main menu or in-game menu.
• The Friends List can be opened via a shortcut (default is O).
• The Friends button displays a notification badge with the number of friend requests, up to 5, after which it displays "more".
• The Friends List is presented as an overlay with two tabs:
  • Friends: Displays current friends, where you can remove friends or send friend requests by entering a player's profile name.
  • Requests: Displays received friend requests (accept or decline) and sent friend requests (cancel).
• Friend online status is displayed below their name, with four states:
  • Offline
  • Online
  • In a world
  • In a joinable world
• Actions such as sending, accepting, declining, and canceling are confirmed in the interface; clear error messages appear if the service is unreachable, rate-limited, or if the requested profile name does not exist.
• Changes to friends during gameplay are notified via pop-ups:
  • Friend request sent;
  • Friend request received;
  • Another player accepted a request sent by the player.
• Pop-up notifications display the player's skin face if available.
• The Friends List checks for updates once per minute while open, otherwise every 5 minutes.
• A confirmation dialog appears the first time the Friends button is shown on the title screen, asking if the player agrees to use the Friends List.
• Friends List, player request privacy, and Microsoft account safety settings links are managed in the new Friends List section under "Online Options".
• If a player sets their chat settings to "Friends Only" in their Xbox profile, they will only receive chat messages from friends.
• Known issues:
  • Canceling a friend request before the recipient accepts may cause the recipient's acceptance list to be out of sync.
    • The recipient will still see the friend request, but accepting it will turn it into a request to the sender.
  • Declining a friend request causes the sender's sent list to be out of sync.
    • The sender must also cancel the friend request to restore the correct sync state.
  • If a player has the Friends List enabled but has disabled the "Allow Requests" setting, other players cannot accept their friend requests.
  • If a player's Xbox profile chat setting is "Friends Only", they will not see their own chat messages.
