26.1, the release of Tiny Takeover, is a game drop for Java Edition released on March 24, 2026,^[1] which adds new textures and models for every baby mob that did not already have a unique model, adds the golden dandelion, makes name tags craftable, makes technical changes, and fixes bugs.

This is the first Java Edition release version to use the new "year.drop.hotfix" version format announced in December 2025,^[2] and to be fully unobfuscated without an accompanying obfuscated variant.^[3][4] It is the first version released in 2026 and the first to require Java 25.

Golden dandelion

• Crafted with a dandelion and 8 gold nuggets:

• Can also be bought from wandering traders.
• When used on a baby mob, it will stop aging. This sets NBT attribute AgeLocked to 1.
  • When used again, it will continue to age again. This sets NBT attribute AgeLocked to 0.
• Golden dandelions have different particles depending on if it is used to start or stop aging.
  • When aging is stopped, green particles moving downwards will be shown.
  • When aging is started, green particles moving upwards will be shown.
• Cannot be used on monsters (including undead mounts, but excluding baby hoglins) and villagers.
• Can be placed and potted like other flowers.
• Can be used to craft yellow dye and a Saturation suspicious stew.

/swing

• New command that enables swinging of entities' arms.
• Not all entities support swing animation. /swing will succeed for those entities, but clients will only display it when possible.

• Time markers will exist within the context of a specific world clock. This means that even though the different time markers are defined by different Timelines, only one Time Marker can exist with a particular id for a particular world clock. It also means that two world clocks can have a time marker with the same name.
  • Built-in uses of time markers
    • Some time markers are used to drive Vanilla game behavior. Usually, they are configured to not show up in /time commands.

  • Wandering Traders have the following tags: #wandering_trader/buying, #wandering_trader/special, #wandering_trader/common.

World clocks

• Each world clock contains an internal time that increases every tick. A world clock can be defined in data packs under the world_clock registry (i.e. found under data/<namespace>/world_clock/<id>.json)
• A world clock can be paused or resumed, and the time of the clock can be changed or queried, using the /time command.
  • This allows different dimensions to have different clocks.
• Format: object with no fields

• Stone can now be directly crafted into its cobblestone variants in the stonecutter.

Tripwire

• The tripwire texture is now rendered as alpha cutout instead of transparent. In other words, the texture is now opaque thus making tripwire easier to see.

Bundles

• Now supports a bundle_contents component with a weight greater than 2³¹-1, equivalent to 2³¹-1 stacks.
  • Previously, the component was removed when the limit was exceeded.
  • A bundle exceeding this limit is shown as full, however, when attempting to empty it, add a new item, or view the tooltip, it still appears empty.

Item stack

• Now, in many cases, it is treated as empty if it has conflicting data, such as having a count greater than max_stack_size, or having max_stack_size greater than one along with max_damage.
  • When mining a shulker box containing an item stack with a conflicting data, it will treat the item as Air x0 in the tooltip, and placing it in a block the item stack will be removed.
  • Shooting an arrow with a conflicting data using a crossbow will not be a project.
  • Using a bundle to remove an item stack with a conflicting data, no items will be dropped.
  • Item stacks with conflicting data can still be placed in chests and in the inventory.

Name tag

• Can now be crafted with 1 paper and 1 nugget.

Spear

• The dismount speed thresholds have been updated to match Bedrock Edition.

Axolotl

• Baby axolotls now have a play dead animation.

Rabbit

• Updated model and texture
  • Programmer Art textures have been removed following the model change.

Pig

• Pig sound variants now have sound for eating.

Polar bear

• Baby polar bears no longer attack foxes, to match Bedrock Edition.

Armor stand

• Small armor stands now display correctly by using the adult armor and scaling it down (/attribute scale).

/fetchprofile

• Added a new entity subcommand that will print profile information from entity in world.
  • Syntax: /fetchprofile entity <single entity selector>
  • If targeted entity does not have profile (currently only Players and Mannequins do) this command will fail.

/time

• The /time command is now based on world clocks.
  • A clock can be optionally specified as an input for the time command with /time of <clock> ....
  • If the clock is not specified (/time ... as before), the default clock for the dimension is used.
• The return value (e.g. from /execute store) from the set and add subcommands is now the total elapsed ticks of the clock instead of the current time of day.
• Syntax:
  • /time [of <clock>] set <time> – sets the total elapsed ticks of the clock.
  • /time [of <clock>] set <timemarker> – advances the clock forward to the next occurrence of the time marker.
    • For the minecraft:overworld clock, the available time markers are: day, noon, night, and midnight
  • /time [of <clock>] add <time> – adds ticks to the clock, can be a negative or a positive number.
  • /time [of <clock>] pause – pauses the clock.
  • /time [of <clock>] resume – resumes the clock.
  • /time [of <clock>] query <timeline> – displays and returns the current number of ticks within the timeline's period.
  • /time [of <clock>] query <timeline> repetition – displays and returns the number of times the timeline's period has repeated.
  • /time [of <clock>] query time – displays and returns the total elapsed ticks of the clock.
  • /time query gametime – as before, the total elapsed ticks within the world (unaffected by changes made to clocks using /time).
  • /time [of <clock>] rate <rate> – sets the rate multiplier at which the clock should advance.
    • This only changes the rate at which the world clock and any timelines dependent on it advance their internal timers.
      • For example, in the case of the minecraft:overworld clock, the day/night cycle will pass quicker with a larger value, but actual game simulation will not speed up (as would happen with /tick rate).
    • A rate of 1 corresponds to normal speed.
    • rate is a float between 0 (exclusive) and 1000 (inclusive).

Trading

• The master librarian no longer offers name tags.
• The master librarian will now offer red candles and yellow candles for the price of three emeralds.
• The wandering trader will now offer name tags for the price of one emerald.

• The game no longer runs on GPUs with 512 megabytes or less of RAM.^{[verify for Java Edition]}

Block model

• Any block model can now support cutout or translucent (partially transparent pixels) textures.
  • Whether a quad is rendered in the cutout or translucent render pass is determined by the contents of its assigned sprite.
    • Any sprite with translucent (partially transparent) pixels will be assigned to the "translucent" pass.
    • Any sprite with fully transparent pixels will be assigned to the "cutout" pass.
    • All other sprites are assigned to the "solid" pass.
• The format of the textures map has been updated:
  • Non-string entries will now be rejected, instead of interpreted as strings.
  • Alongside the previous inline sprite ID form, entries can now be defined as an object with fields:
    • sprite – the sprite ID
    • force_translucent – optional boolean, true if any geometry with this texture should be forced into the "translucent" pass.
      • This is useful for example for blocks that don't have any translucent pixels, but use the mean mipmap strategy.
      • Default: false

Block states

• The rotation property in default block state of banners and signs has been changed from 0 to 8

Timelines

• Added a clock field: a world clock ID, specifies which world clock the timeline is tied to.
  • This field is required, but to match previous behavior the minecraft:overworld clock can be used
• Added an optional time_markers field, an optional map between namespaced Time Marker IDs and either an int or a Time Marker object.
  • Format:
    • Non-negative int, the tick that the time marker marks.
    • Or object with fields:
      • ticks: int between 0 and period_ticks, the tick that the time marker marks.
      • show_in_commands: optional boolean, specifies whether the Time Marker will show up in command suggestions.
        • Default: false

UI

• Worlds that need to be upgraded will now show Upgrade and Play instead of Play Selected World.
  • The Edit World and Re-Create World buttons are disabled until the world has been upgraded.
• When starting such a world, a new upgrade progress screen will be shown.
• Added new UI sprites: gui/sprites/widget/preedit.png for IME preedit overlay background.
• If there are no screens open, IME input will be cancelled.
• IME will be opened when a text input gains focus and closed when a text input loses focus.
• sound_cache debug entry has been added.

User interface

• Input Method Editors (IME) candidates will now be shown in-game (on supported platforms, currently Windows and macOS) above currently edited text field.
• Fullscreen no longer uses exclusive mode.

World generation

• Rule-based block state providers have changed so that their fallback is optional and can be empty.
  • In such cases that an empty fallback is invoked, features that use them will not place anything.
  • Current configuration that uses a rule-based block state provider is the state_provider in the disk feature.
• forest_rock configured feature has been renamed to block_blob
• block_blob feature configuration has changed to support the following parameters:
  • state – The block the rock is made out of.
  • can_place_on – A block predicate that defines which blocks the rock can be placed on.
• ice_spike configured feature has been renamed to spike
• spike feature configuration now supports the following parameters:
  • state – The block the spike is made out of.
  • can_place_on – A block predicate that defines which blocks the spike can be placed on.
  • can_replace – A block predicate that defines which blocks the spike can replace.
• huge_red_mushroom and huge_brown_mushroom feature configurations have a new parameter:
  • can_place_on – A block predicate that defines which blocks the huge mushroom can be placed on.
• alter_ground tree decorator configuration has changed so that provider is now a rule-based block state provider.
• tree feature configuration has replaced the force_dirt and dirt_provider parameters with a single below_trunk_provider rule-based block state provider:
  • Format:
    • fallback – An optional block state provider.
    • rules – A list of rules.
      • if_true – A block predicate that checks the block position before providing the block.
      • then – A block state provider.
    • Default value:

"below_trunk_provider":{
"rules":[
{
"if_true":{
"type":"minecraft:not",
"predicate":{
"type":"minecraft:matching_block_tag",
"tag":"minecraft:cannot_replace_below_tree_trunk"
}
},
"then":{
"type":"minecraft:simple_state_provider",
"state":{
"Name":"minecraft:dirt"
}
}
}
]
}

• Any trees that previously used force_dirt have a below_trunk_provider that always provides a dirt block instead.
• Block state providers now have a new type called rule_based_state_provider
  • This was previously a separately parsed type but is now instead a sub-type of block state providers.
  • They can now be used in any other feature configurations as a block state provider and are no longer unique to the disk feature.
  • Format:
    • fallback – An optional block state provider
    • rules – A list of rules
      • if_true – A block predicate that checks the block position before providing the block
      • then – A block state provider

• Flower features
  • Features spawned from Bone Meal are no longer restricted to the flower feature type, and instead controlled by the #can_spawn_from_bone_meal configured feature tag.
  • The flower, flower_no_bonemeal, and random_patch feature types have been removed.
    • Instead, patches can be expressed as a sequence of count and random_offset placement modifiers.

• Int Providers
  • Added the trapezoid int provider
    • Selects a random value with a trapezoid distribution, similar to the trapezoid float provider.
    • Format: object with fields:
      • min: integer, the minimum value to generate.
      • max: integer, the maximum value to generate.
      • plateau: integer, the width of the "plateau" of the distribution in which all values are equally likely to occur.
        • A value of 0 is equivalent to a triangle distribution.
        • A value of max-min is equivalent to a uniform distribution.

• count placement modifier
  • The count field is now limited to a range of 0 to 4096 instead of the previous 256.
