Additions

Items

Nautilus armor

• Equippable on nautiluses and zombie nautiluses.
• Has copper, iron, gold, diamond, and netherite variants.
  • Copper, iron, golden, and diamond nautilus armor now have a chance to be found in the chests for the following structures:
    • Buried treasure
    • Ocean ruins
    • Shipwreck
  • Copper, iron and golden nautilus armor can be smelted into the respective nuggets.

Spawn eggs

• Added nautilus and zombie nautilus spawn eggs.

Spear

• New weapon that can be crafted in wood, stone, copper, iron, gold, diamond and netherite versions.
  • Each material has different stats for timing, influencing how fast they are to use.
  • Copper, iron and golden spears can be smelted into the respective nuggets.
• Cannot be used to mine blocks, as opposed to other weapons.
• Can be enchanted with the exclusive enchantment Lunge, in addition to the available enchantments for swords (except Sweeping Edge).
• Has a minimum reach for damage, being too close to a target will yield no damage.
  • Has extended maximum reach compared to other tools and weapons.
• Zombies, husks, zombified piglins and piglins can spawn holding a spear.
• Has two attacks: jab and charge.
  • Jab
    • Used by quick-pressing the primary action button.
    • Is a low-damage attack with knockback.
    • Has a cooldown between attacks.
    • Wooden spears have the fastest cooldown, while netherite has the slowest.
    • Can hit multiple enemies.
  • Charge
    • Used by holding the secondary action button.
    • Damage is based on spear material, the player’s view angle, and the velocity of both the player and the target.
    • While holding down the button, the attack goes through three stages before returning to idle:
      • Engaged: The spear can deal damage, knockback, and dismount mounted enemies if the speed is above the required thresholds.
      • Tired: Indicated by the spear rotating to a vertical position and shaking. The Spear can deal damage and knockback (but not dismount) if the speed is above the required thresholds.
      • Disengaged: Indicated by the spear being lowered, pointing downwards. The Spear gives damage but not knockback or dismount if the speed is above the required threshold.
    • The spear's range when used by mobs is half of that when used by players, but they can deal damage, dismount and knockback at lower speeds than the players.

Mobs

Nautilus

• A new neutral aquatic mob.
• Spawns in all ocean biomes.
• Has 15HP × 7.5 health.

• Once tamed, has a roaming restriction around its home position of 16 blocks with a saddle, and 32 blocks without.
• Has a 5% (¹⁄₂₀) chance of dropping a nautilus shell upon death, on a player kill, unaffected by Looting.

Zombie nautilus

• A new underwater mob that spawns with a Drowned rider wielding a trident.
• Hostile only if ridden by a hostile mob.
• Behaves similar to the nautilus except that it cannot be bred.

    • Available presets are "Fast", "Fancy", "Fabulous!" and "Custom"
    • The default preset is "Fancy" for new players.
    • But for players who are upgrading to this version the preset will be set to "Custom" to preserve the current configuration.

Textures

• All blocks in the world now have mipmaps applied if enabled in video settings.
  • Blocks that did not have mipmaps before, such as different vines, rails, foliage (apart from leaves) and more should look better from higher distances.
• texture section of *.mcmeta files has a new boolean field darkened_cutout_mipmap
  • The default value is false
  • It is set to true for the block textures that had mipmaps before this version:
    • All leaf types and mangrove roots.
  • If the field is set to true and the texture is cutout the mipmaps will be darkened to emulate the darker interior of the block, this was the behavior for cutout mipmapped blocks before this version.
  • Leaving the field unset or setting it to false will generate mipmaps without darkening, and it fits well for other types of cutout blocks that do not have dark interior such as flowers, grasses, vines, rails, etc.
• Only mipmaps of level 0 and 1 are now animated for block animated textures.
• Glass and glass panes now support translucent textures.

UI

25w43a

25w43a is the third snapshot for Java Edition 1.21.11,^{[unofficial name]} released on October 21, 2025, which makes some tweaks to spear mechanics.^[3]

Additions

General

Loot functions

• minecraft:discard
  • Replaces any item stack with empty one.
  • No fields.

Changes

Items

Spear

• Spears now deal more damage through charge attacks dealt by players, but also mobs. This is because the spear's charge attacks now deal the attack damage attribute's base value on top of their formula.
• The spear model is now slightly larger.
• Spears now provide visual feedback when they hit a target in the charge attack.

Mobs

Nautilus

• Can no longer enter boats.

Zombie nautilus

• Can no longer enter boats.
• No longer suffocates outside water.

Command format

/worldborder

• The time argument is now given in ticks instead of seconds.

Gameplay

Enchantments

• Using Lunge no longer causes durability damage to the spear.
• Using Lunge now consumes hunger points by exhausting the player, similar to sprinting or jumping.
  • Level I consumes 3 (), level II consumes 4 (), and level III consumes 5 ().
  • Lunge can only be used if the player has at least 6 () hunger points in their hunger bar.

World border

• World border interpolation is now dependent on game ticks instead of real time.
  • This means the world border will no longer move when the game is paused.
  • It will also respect any changes made by the /tick command.

General

Data pack

• The pack format version is now 91.0.

Enchantment definition

• Entity Effects
  • minecraft:apply_exhaustion: applies exhaustion to the targeted entity.
    • amount - Level-Based Value indicating the amount of exhaustion to apply.
    • Effective only on players.

Loot functions

• minecraft:filtered
  • The field modifier has been replaced with two fields:
    • on_pass - function or a list of functions to run when item_filter predicate passes.
    • on_fail - function or a list of functions to run when item_filter predicate fails.

LWJGL

• Updated the LWJGL library to version 3.3.6.

Resource pack

• The version is now 71.0.

Sounds

• Added new sound event for the Nautilus:
  • item.underwater_saddle.equip

Tags

• Added nautilus, and zombie_nautilus to #cannot_be_pushed_onto_boats entity tag.

Textures

• The darkened_cutout_mipmap field of the texture section of *.mcmeta files has been replaced by a new field mipmap_strategy with the following supported values:
  • mean averages both color and alpha between groups of four pixels for the current mipmap level to generate the next mipmap level pixel. This was and stays the default strategy for most solid or translucent full block textures.
  • dark_cutout is similar to mean, but blends colors in a way that makes the pixels bordering cutout pixels darker. This was and stays the strategy for leaves and mangrove roots. It simulates dark interior of the blocks.
  • cutout is a new strategy that always generates a mipmap based on the original texture instead of the previous mipmap. Used for most cutout blocks that became mipmapped in this version.
  • strict_cutout is a modification of cutout that uses stricter alpha cutoff value leading to the textures using this value disappearing at higher mipmap levels. Is used for flowers and similar blocks to avoid artifacts.
  • auto is the default value and will make the game to pick mean for textures that do not contain fully transparent pixels and cutout for those that do.
• All mipmap levels are once again animated for block animated textures.
• Beacon and redstone dust now support translucent textures.

  • Format:
    • slot_source: a slot source describing where the items are located.
  • Supports all standard loot pool entry fields.
• Removed contents as a supported value for the dynamic loot entry type.
  • Its behaviour of providing the contents of a Shulker Box was made redundant by the addition of the slots loot entry type, and can now be replicated with the slot_range slot source.

• Added ChunkSection uniform, used by terrain.vsh (which replaces DynamicTransforms).
• New shaders have been introduced to perform GPU based sprite animations.
• Globals uniform now has camera coordinates.

Shaders & Post-process Effects

• Added animate_sprite* core shaders, which use a new SpriteAnimationInfo uniform.

Sprite Animations

• Sprites (textures as part of a larger atlas) are now animated on the GPU rather than per-tick on the CPU.
• For regular frame-based animations, animate_sprite.vsh and animate_sprite_blit.fsh are used to perform the draw.
• For interpolated animations, animate_sprite.vsh and animate_sprite_interpolate.fsh are used to perform the draw.
• The UBO SpriteAnimationInfo contains information on where the sprite should be drawn to, within the greater texture atlas.

Statistics

• Added minecraft:nautilus_one_cm statistic (Distance By Nautilus).

Tags

Timelines

• Are a new experimental concept defined in data packs under the timeline registry (i.e. found under data/<namespace>/timeline/<id>.json).
• Specify game behavior based on the absolute day time (that which is set by /time set). Timelines optionally can specify a period over which they will be repeated.
• Are able to modify game behavior or visuals by acting as an Environment Attribute source to apply Environment Attribute modifiers.
  • Format: object with fields
    • period_ticks: optional integer, defines the duration in ticks over which the timeline will repeat.
      • If not specified, the timeline will not repeat
    • tracks: optional map between Environment Attribute IDs and a corresponding Environment Attribute Track object.
• Timelines by default have no effect unless they are included by a dimension.
• With the inclusion of Timelines, Environment Attribute sources are processed in the following order (from low to high priority):
  • Dimensions
  • Biomes
  • Timelines
  • Weather (not data-driven)
• Interpolation
  • Timelines can define Attribute Tracks
    • These specify how a modifier for a particular Environment Attribute changes over time by defining keyframes.
    • Depending on the attribute, interpolation may be used between each keyframe. If interpolation is not used, the previous keyframe value will always be selected.
  • For example, a Timeline with a period of 24000 might be set up as following:
    • At time = 0, the timeline provides sky_color = #ff0000 (red)
    • At time = 1000, the timeline provides sky_color = #ff0000 (red)
    • At time = 6000, the timeline provides sky_color = #ff00ff (magenta)
  • Between time = 0 and time = 1000, the sky color will be red. Between 1000 and 6000, it will shift from red to magenta. Then, from 6000 all the way until the timeline repeats and reaches time = 0 again, the color will slowly shift back to red.
  • Unlike biomes, if a Timeline uses a modifier instead of an override, interpolation is applied to the modifier arguments rather than the final modified values.
• Attribute Tracks
  • An Attribute Track specified within a Timeline takes the format of an object with the following fields:
    • ease - optional Easing Type (see below), used to ease the interpolaton of the value between keyframes.
      • Default: linear
        • If the target attribute does not support interpolation, the easing mode will have no effect.
    • keyframes - list of keyframe objects, must be ordered by the ticks field:
      • ticks - integer between 0 and period_ticks (if specified), defines the tick (within the period) at which this keyframe's value will be active.
      • value - the modifier argument (format dependent on the chosen modifier).
        • If no modifier is specified (or override is used), the type of this field is the same as the Environment Attribute itself.
        • How this value is used depends on the type of modifier.
          • Note: at most two keyframes can be placed on the same tick, creating an immediate transition.
    • modifier - optional string modifier ID, dependent on the Attribute Type (see the Common Modifiers section below).
      • Default: override
  • For example, the following Timeline has a period of 24000, and has an attribute track that modifies only minecraft:gameplay/cat_waking_up_gift_chance. Because the easing is constant, between tick 362 and 23667 the value is 0.0, while between tick 23667 and 362 it is 0.7.
  • Like other Environment Attribute sources, the specified value is used as the argument to the specified modifier. This is then applied on top of sources with a lower priority. In this case the modifier is maximum, so this timeline will only ever increase the value of cat_waking_up_gift_chance to the value specified in the track.

{
    "period_ticks": 24000,
    "tracks": {
        "minecraft:gameplay/cat_waking_up_gift_chance": {
            "ease": "constant",
            "modifier": "maximum",
            "keyframes": [
                { "ticks": 362,   "value": 0.0 },
                { "ticks": 23667, "value": 0.7 }
            ]
        }
    }
}
