'''Preview 26.20.23''' (Windows, iOS, iPadOS, Xbox, PlayStation), or '''Beta 26.20.24''' (ChromeOS, Android) is the fourth beta/''Preview'' for [[Minecraft:Bedrock Edition 26.20]], released on March 31, 2026,<ref>{{cite|url=https://feedback.minecraft.net/hc/en-us/articles/44725242220429-Minecraft-Beta-Preview-26-20-23-24|title=Minecraft Beta & Preview - 26.20.23/24|website=Minecraft Feedback|date=March 31, 2026}}</ref> which adds the [[Minecraft:sulfur caves]], [[Minecraft:sulfur]] and [[Minecraft:cinnabar]] block sets, and [[Minecraft:sulfur cube]] behind an experiment, and fixes bugs.

== Changes ==
=== General ===
'''[[Minecraft:Mob]]s'''
* [[Minecraft:Ravager]]s can only destroy [[Minecraft:leaves]] and [[Minecraft:crops]] when running into them, and can no longer destroy [[Minecraft:snow]], [[Minecraft:turtle egg]]s or various plant blocks. This better matches their behavior in {{JE}}.
** Unlike {{JE}}, they are still able to destroy [[Minecraft:pumpkin stem]]s and [[Minecraft:melon stem]]s.

'''Graphical'''
* {{cd|minecraft:atmosphere_settings}} and {{cd|minecraft:atmosphere_settings/description}} are now required in the {{cd|1.26.20}} version of the [[Minecraft:Vibrant Visuals#Atmospherics 2|atmospherics]] config file.
* Accessing atmospherics graphics overrrides through [[Minecraft:scripting]] is now done from {{cd|getBiomeAtmospherics}}.

'''[[Minecraft:Realms]]'''
* Added functionality for the "Resource packs" and "Behavior packs" tabs in the new [[Minecraft:edit world]] screen.
* Replaced the development notice for the upcoming "Admin log" with a message that settings, community, and world changes will be logged here, but it is not functional yet.

=== Technical ===
'''AI Goals'''
* Made schemas for the following goals stricter when parsing and will fail to load an entity json that has invalid data in versions 1.26.20 and newer:
** {{cd|minecraft:behavior.pet_sleep_with_owner}}
** {{cd|minecraft:behavior.pickup_items}}
** {{cd|minecraft:behavior.player_ride_tamed}}
* Refactored {{cd|minecraft:behavior.follow_target_captain}} to {{cd|minecraft:behavior.follow_target_leader}}. The following fields have been added to the behavior:
** {{cd|always_look_for_leader}}: If {{cd|true}}, the mob will always search for a valid leader to follow if none is found or current leader is not valid anymore.
** {{cd|leader_filters}}: The filters to use when determining if a mob is a suitable leader or not.
** {{cd|search_cooldown}}: (default: {{cd|20}}) Number of ticks that must pass before a new search is initiated after a target is not found, lost, or becomes invalid.

'''API'''
* Added beta read-only property {{cd|partyInfo}} to {{cd|Player}} that returns a {{cd|PartyInfo}} object {{cd|{ partyId: string, isLeader: boolean <nowiki>}</nowiki>}} or undefined if the player is not in a party.
* Added settings under "Creator" section to configure text filtering debug delay.
* Moved {{cd|function Entity.addItem}} from {{cd|beta}} to {{cd|v2.7.0}}.
* Moved {{cd|class InvalidEntityComponentError}} from {{cd|beta}} to {{cd|v2.7.0}}.

'''Biomes'''
* Added {{cd|minecraft:subsurface_builder}} field to Biome Json API.
** Sub Surface Builders allow specifying a {{cd|minecraft:surface_builder}} to be applied to biomes located underneath the Overworld's terrain surface.
* Added {{cd|minecraft:noise_gradient}} sub surface builder type, which places continuous bands of blocks according to a noise distribution.
** This surface builder has the following parameters:
*** {{cd|non_replaceable_blocks}}: a list of blocks that the surface builder is not allowed to replace.
**** Leaving this list empty or unspecified will allow the replacement of any block type.
*** {{cd|gradient_blocks}}: a list of block names that will be sampled according to a Perlin noise distribution.
**** Specifying {{cd|minecraft:air-blocks}} is permitted, and will result in the original block not being replaced, meaning it is possible to adjust the density/intensity of block replacement in the biome using this surface builder type.

'''Entity components'''
* Added the {{cd|minecraft:bounciness}} component, which controls how an entity bounces when colliding with surfaces.
** Contains a single field, {{cd|value}}, defining the bounce strength:
*** {{cd|0}} results in no bounce.
*** {{cd|1}} results in a perfectly elastic collision with full energy preservation.
** If the component is not present, bounciness defaults to {{cd|0}}.
** Only available if the entity's {{cd|format_version}} is set to {{cd|beta}}.
* Added the {{cd|minecraft:apply_knockback_rules}} component, which controls how an entity applies knockback to a target.
** {{cd|horizontal_power}} defines how much the target is hit backwards.
*** Defaults to {{cd|1.0}} if not defined.
** {{cd|vertical_power}} defines how much the target is hit upwards.
*** Defaults to {{cd|0.4}} if not defined.
** {{cd|vertical_velocity_cap}} defines the target's maximum vertical upwards velocity after the target's knockback rules have been evaluated.
*** Defaults to {{cd|0.4}} if not defined.
** {{cd|check_if_target_is_immersed_in_water}} defines whether the target should be fully immersed in water for the knockback rules to apply.
*** Defaults to {{cd|false}} if not defined.
* Added the {{cd|minecraft:air_drag_modifier}} component.
** The higher its value, the more air drag affects an entity:
*** {{cd|0.0}} means no air drag.
*** {{cd|1.0}} means regular air drag.
*** {{cd|2.0}} means double air drag.
** Only available if the entity's {{cd|format_version}} is set to {{cd|beta}}.
* The {{cd|minecraft:knockback_resistance}} component now accepts negative values down to a minimum of {{cd|-2}}, resulting in knockback being increased instead of being diminished.

'''Network Protocol'''
* Added the bool {{cd|Filter Profanity Change}} to the Packet {{cd|UpdateClientOptionsPacket}}.

== Experimental ==
These additions and changes are accessible by enabling the "Beta APIs", "Upcoming Creator Features", "Render Dragon Features for Creators", "Experimental Voxel Shape Features", the new "[[Minecraft:Chaos Cubed|Drop 2 of 2026]]", and "Experimental Custom Projectile Features" [[Minecraft:experimental]] toggles.

=== Additions ===

[[File:Sulfur.png|32px]] '''[[Minecraft:Sulfur]]'''
* A yellow-colored block that generates in sulfur caves.
* Used to craft or cut sulfur [[File:Sulfur_Stairs.png|width=32x32]] [[Minecraft:Sulfur Stairs|stairs]], [[File:Sulfur_Slab.png|width=32x32]] [[Minecraft:Sulfur Slab|slabs]], [[File:Sulfur_Wall.png|width=32x32]] [[Minecraft:Sulfur Wall|walls]], [[File:Polished_Sulfur.png|width=32x32]] '''[[Minecraft:polished sulfur]]''', [[File:Polished_Sulfur_Stairs.png|width=32x32]] [[Minecraft:Polished Sulfur Stairs|stairs]], [[File:Polished_Sulfur_Slab.png|width=32x32]] [[Minecraft:Polished Sulfur Slab|slabs]], [[File:Polished_Sulfur_Wall.png|width=32x32]] [[Minecraft:Polished Sulfur Wall|walls]], [[File:Sulfer_Bricks.png|width=32x32]] '''[[Minecraft:sulfur bricks]]''', [[File:Sulfur_Brick_Stairs.png|width=32x32]] [[Minecraft:Sulfur Brick Stairs|brick stairs]], [[File:Sulfur_Brick_Slab.png|width=32x32]] [[Minecraft:Sulfur Brick Slab|brick slabs]], [[File:Sulfur_Brick_Wall.png|width=32x32]] [[Minecraft:Sulfur Brick Wall|brick walls]], and [[File:Chiseled_Sulfur.png|width=32x32]] '''[[Minecraft:chiseled sulfur]]'''.

[[File:Potent Sulfur.png|32px]] '''[[Minecraft:Potent sulfur]]'''
* A variant of sulfur that emits bubbles when placed underwater. It also produces a cluster of noxious gas particles in the water's surface.
* Players and mobs get [[Minecraft:Nausea]] when they enter water that is near and directly or indirectly connected to the block.

==== Items ====
[[File:Sulfur Cube Spawn Egg.png|32px]] '''[[Minecraft:Sulfur cube spawn egg]]'''
* Used to spawn a sulfur cube.

[[File:Bucket of Sulfur Cube.png|32px]] '''[[Minecraft:Bucket of sulfur cube]]'''
* Obtained by {{ctrl|using}} a [[Minecraft:bucket]] on a [[Minecraft:sulfur cube]].
* When used, spawns a sulfur cube.

==== Mobs ====
[[File:Sulfur Cube.png|32px]] '''[[Minecraft:Sulfur cube]]'''
* A [[Minecraft:passive]] slime-like mob that spawns in sulfur caves.
* Immune to fall damage.
* When killed, it will split into 2 small cubes, like other slime-like mobs.
** Unlike the [[Minecraft:slime]] and [[Minecraft:magma cube]], the small versions can grow up into the large version, like how a [[Minecraft:baby]] mob works.
* It is attracted to the [[Minecraft:Item (entity)|dropped item]] form of full blocks. The cube can pick up a block, or a player can {{ctrl|use}} a full block on the cube, causing the cube to absorb it into its body.
** [[File:Sulfur Cube Stone.png|32px]] In this state, they become immobile and cannot be damaged by most entities. Instead it will be knocked back when attacked.
*** The knockback also depends on the damage that would have been dealt, with stronger attacks sending the cube further.
** [[Minecraft:Shearing]] it removes and drops the block, reverting back to normal.
** Depending on the full block, they will behave differently when punched while in its immobile state, examples are:
*** [[Minecraft:Blocks of iron]] make it heavy, i.e. it will have higher gravity.
*** [[Minecraft:Wool]] makes it floaty, i.e. it will have lower gravity.
*** Wooden [[Minecraft:log]]s and [[Minecraft:stem]]s make it bouncy.
*** [[Minecraft:Ice]] reduces its friction, making it slide more.
* Can be caught in [[Minecraft:bucket]]s to move it.

==== Technical ====
'''Items'''
* Added tags for [[Minecraft:sulfur cube]]s to make use of for physics determination and absorbing
** {{cd|minecraft:sulfur_cube_archetype_bouncy}}
** {{cd|minecraft:sulfur_cube_archetype_regular}}
** {{cd|minecraft:sulfur_cube_archetype_slow_flat}}
** {{cd|minecraft:sulfur_cube_archetype_fast_flat}}

** {{cd|minecraft:sulfur_cube_archetype_fast_sliding}}
** {{cd|minecraft:sulfur_cube_archetype_slow_sliding}}
** {{cd|minecraft:sulfur_cube_archetype_sticky}}
** {{cd|minecraft:sulfur_cube_archetype_high_resistance}}

==== World generation ====
'''{{BiomeLink|Sulfur Caves}}'''
* A cave biome composed of [[Minecraft:sulfur]] and [[Minecraft:cinnabar]] blocks.
* [[Minecraft:Sulfur cube]]s spawn here.
* Have a high concentration of [[Minecraft:glow lichen]].
* [[Minecraft:Sulfur pool]]s also generate here.

'''{{EnvLink|Sulfur Pool}}'''
* Greenish pools that generate in sulfur caves.
* Consists of a body of water surrounded by sulfur blocks and cinnabar with [[Minecraft:potent sulfur]] generating at the bottom, which inflicts [[Minecraft:Nausea]] to mobs in the pool.

'''{{EnvLink|Sulfur Spring}}'''
* A pile of [[Minecraft:sulfur]] with a small sulfur pool on the surface.
* Generates on the surface indicating the presence of sulfur caves below.

=== Changes ===
==== Technical ====
'''[[Minecraft:Add-Ons]]'''
* Added experimental toggle "Custom Projectiles" which enables improvements around custom projectiles in add-ons without the use of runtime identifiers.
** Adds {{cd|isolated_physics}} property to minecraft:projectile component for easier trajectory control.
** {{cd|fire_at_target}} goal now applies projectile offsets relative to entity rotation.
** Custom projectiles now:
*** Can be reflected.
*** Update their owner upon launch and reflection.
*** No longer collide with their owner on launch.
*** Apply their offsets on launch.
*** Remain at their point of impact when using {{cd|stick_in_ground}}.

'''[[Minecraft:API]]'''
* Added {{cd|maximumRenderDistance}} to {{cd|DebugShape}} in {{cd|minecraft@debug-utilities}} could be invisible.
* Added the Script Entity property {{cd|nameplateDepthTested}} to {{cd|beta}}.
* Added the Script Entity property {{cd|nameplateRenderDistance}} to {{cd|beta}}.

* Added {{cd|Player.chatDisplayName}} to {{cd|beta}} - a read-only property returning the composed chat name (chatNamePrefix + name + chatNameSuffix).
* Added {{cd|Player.chatMessagePrefix}} to {{cd|beta}} - an optional string prepended to the text of the player's chat messages, useful for applying color/formatting codes.
* Added {{cd|BlockComponentBlockStateChangeEvent}} to {{cd|beta}} using {{cd|onBlockStateChange}} allows custom components to read a state change.
* Added {{cd|BETA}} Boolean property {{cd|firstUpdate}} to {{cd|BlockComponentRedstoneUpdateEvent}}.

'''DDUI'''
* Class Observable.
** Added the method {{cd|getFilteredText}}. Gets filtered data from the Observable (only available for strings). {{cd|-getFilteredText(this: Observable<T & string>, player: Player): Promise<string {{!}} TextFilteringError>;}}
** Added the enum {{cd|TextFilteringError}}. An enum representing the errors that can occur during text filtering. This is used at {{cd|Observable.getFilteredText}} to provide more context about the filtering process.

'''Scripting'''
* Added scripting method that allows creators to check the snow logging behavior of a block.

'''Voxel Shapes'''
* Added non-unit-cube voxel shapes for 70 blocks when the Voxel Shapes experiment is enabled.
** These shapes improve face culling so that hidden faces between adjacent blocks are correctly removed.
*** Slab shapes (62 blocks)
*** Other shapes (8 blocks): [[Minecraft:calibrated sculk sensor]], [[Minecraft:end portal frame]], [[Minecraft:comparator]] (powered and unpowered), [[Minecraft:repeater]] (powered and unpowered), [[Minecraft:snow]], and [[Minecraft:stonecutter]].
