1.21.5, il rilascio di Spring to Life, è un rilascio rilasciato il 25 marzo 2025.[1] Questo aggiornamento aggiunge nuove varianti per le galline, le mucche, e i maiali, expands plant life, and updates all spawn egg textures. Additionally, several features previously exclusive to Bedrock Edition have been added to Java Edition, enhancing gameplay diversity and visual aesthetics, and also fixes bugs. This is the first version released in 2025.
To run a test in a world, a test instance block is used. This type of block represents the test as placed in the world and is used to interact with that test, to save the structure, reset or run the test.
Using the /test command to run or create a test will also place a test instance block to control that test.
When bred by a player, the baby chicken variant will not be chosen by the current biome, but instead randomly selected from one of the parents' variants.
Dead bush blocks have a chance of playing ambient sounds when placed on top of two blocks that are any color of terracotta, sand or red sand blocks in any biome.
Sand, red sand and terracotta of any color have a chance of playing ambient sounds when surrounded by any one of them on at least 3 sides 8 blocks away.
block.sand.idle can be played in any biome.
block.sand.wind only plays when in desert or badlands biomes.
Any block in the simulation distance of a player or loaded by another source of chunk loading (such as ender pearls) may now receive random ticks, instead of just 8 chunks around players.
For example: if a chunk is loaded by an ender pearl or is in the spawn chunks, crops are able to grow, ice can melt, snow can fall, and a cauldron can be filled by rain.
Mob spawning, lava spreading fire, and lightning strikes still occur in the previous radius of 8 chunks around players.
Landing on powder snow with leather boots equipped after falling further than 2.5 blocks (more precisely ~2.69456... blocks) will now make entities fall through the snow.
Jumping or falling less than 2.5 blocks allows the entity to land on top of the snow like before.
Changed the visuals of all spawn eggs to make them easier to distinguish: each type of spawn egg now has its own unique icon instead of all just being colored variants of the same spotted egg.
Each egg visual varies in shape to reflect the in-world properties of the mob it spawns: for example, smaller mobs tend to have a smaller spawn egg icon.
The changes to cartographer trades have been moved from experimental features and are now available during normal gameplay.
Added seven new maps which cartographers can sell, each pointing to a different village or other structures in a different biome, depending on the biome they come from. These maps can help players who want to quickly find a specific location.
Village maps points to a village in a specific biome. Jungle explorer map points to a jungle pyramid. Swamp explorer map points to a swamp hut.
Cartographers from different village types will sell a different range of maps and colored banners.
Some prices and quantities have also been adjusted.
👁 Image An image referring to how the different maps for the different village types are connected.👁 Image A graph showing where each type of cartographer's maps leads to
Ambient block sounds in deserts, badlands and pale gardens which are only used for ambience have been moved from Blocks to Ambient/Environment category.
The breaking sound for grass sound type has been lowered, affecting all blocks using this sound.
Blocks that are broken by a piston now play their breaking sound.
Shows the local coordinates to the block pointed at in the test.
If the optional variable name is specified, this variable name is used in a code fragment obtained by clicking on the coordinates in the output message.
If multiple tests are run at once, they are placed in a grid and run in parallel, although only up to a certain limit. Beyond that limit, tests are run in rounds where each round completes before any tests from the next round are started.
For each test, loads the given structure and runs the associated test. Each test location will have a beacon beam showcasing the test status.
Gray beacon = in progress
Red = fail (required test)
Orange = fail (optional test)
Green = success
If a test fails, the error is shown on a lectern book and an overlay.
When present, this item can be used like a Shield to block attacks to the holding player.
Format: object with fields
block_delay_seconds
Non-negative float (default: 0).
The number of seconds that right-click must be held before successfully blocking attacks.
bypassed_by – hashtagged damage type tag (optional)
If specified, blocking is bypassed by these damage types.
damage_reductions
List of object with fields (optional)
Controls how much damage should be blocked in a given attack.
If not specified, all damage is blocked.
Each entry in the list contributes an amount of damage to be blocked, optionally filtered by damage type.
Each entry adds to blocked damage, determined by clamp(base + factor * dealt_damage, 0, dealt_damage).
The final damage applied in the attack to the entity is determined by dealt_damage - clamp(blocked_damage, 0, dealt_damage)
Entry format:
type – damage type id, list of damage type ids, or hash-prefixed damage type tag (optional).
This entry will only contribute to the blocked damage if the dealt damage type matches this field.
If not specified, any damage type will be accepted.
base – float
Constant amount of damage to be blocked.
factor – float
Fraction of the dealt damage that should be blocked.
horizontal_blocking_angle – angle in degrees as a positive float
Default: 90
The maximum angle between the user's facing and the incoming attack for the block to be effective.
If the blocked damage has no position, the compared angle will be assumed to be the maximum 180.
disable_cooldown_scale
Non-negative float (default: 1).
Multiplier applied to the number of seconds that the item will be on cooldown for when attacked by a disabling attack (disable_blocking_for_seconds on the weapon component).
If 0, this item can never be disabled by attacks.
item_damage
Object with fields (optional)
Controls how much damage should be applied to the item from a given attack.
If not specified, a point of durability is removed for every point of damage dealt.
The final damage applied to the item is determined by: .
The final value may be negative, causing the item to be repaired.
Format:
threshold – non-negative float
The minimum amount of damage dealt by the attack before item damage is applied to the item.
base – float
Constant amount of damage applied to the item, if threshold is passed.
factor – float
Fraction of the dealt damage that should be applied to the item, if threshold is passed.
block_sound
Sound event (optional).
If specified, this sound will be played when an attack is successfully blocked.
disable_sound
Sound event (optional).
If specified, this sound will be played when the item goes on its disabled cooldown due to an attack.
break_sound component
When present, this sound will be played when the item runs out of durability and breaks.
If not present, no sound will be played on break.
This component is present by default on every item type.
Format: sound event
e.g. break_sound='item.wolf_armor.break'
potion_duration_scale component
When present, for items that have the potion_contents component, the duration of the applied effects will be scaled by this factor.
This also applies to custom_effects in the potion_contents component, unlike the previous hard-coded scaling factor.
If not specified, defaults to 1.0.
Format: non-negative float
e.g. potion_duration_scale=0.25
provides_banner_patterns component
When present, this item can be placed in the pattern slot of a Loom.
Format: hash-prefixed banner pattern tag.
e.g. provides_banner_patterns='#minecraft:pattern_item/globe'
provides_trim_material component
When present, this item will provide the specified trim material when used in a trimming recipe.
Note that to be used in the built-in smithing recipes, the item must also be in the #trim_material tag.
As such, the trim material registry definition no longer specifies an item.
Format: trim material id
e.g. provides_trim_material='minecraft:iron'
tooltip_display component
This component allows the tooltips provided specifically by any given item component to be suppressed.
This replaces the previous show_in_tooltip fields, hide_additional_tooltip and hide_tooltip components.
Format: object with fields:
hide_tooltip - boolean (default: false).
If true, the item will have no tooltip when hovered.
hidden_components - list of item component ids (default: []).
The tooltips provided by any component in this list will be hidden.
If that component provides no tooltip, it will have no effect.
weapon component
When present, the 'Item Used' statistic will be incremented for each attack with the item.
The specified amount of damage can be done to the item with each attack.
Added #spawns_cold_variant_farm_animals – all biomes where cold variant of farm animals spawn.

Arguments in commands that accept inline values like loot tables, predicates, modifiers, data components, formatted text (/loot, /give, /tellraw, /execute if predicate, data components in /execute if items, etc.) have been reverted to accept numbers in place of booleans.
Text components in commands such as /tellraw or /title are now specified with SNBT instead of JSON.
Text style in the /scoreboard command when specifying the styled number format is now specified with SNBT instead of JSON.
The behavior of /setblock and /fill commands have changed in how they handle block entity data:
If the block entity data is not specified, and the existing block has data, the block entity data will be preserved.
If the block entity data is specified, the block entity data will be set to the specified value.
To clear the block entity data explicitly, the block entity data must be specified as {}.
The operation is now successful if either the block state changed or the block entity data changed.
Any interface with NBT data within the game (SNBT representation, /data) now supports heterogeneous lists, i.e. ones where elements are not of the same type
Inserting or replacing into a list of a different type with /data will no longer give an error.
Inserting into an array type (e.g. [I;1,2,3]) is still type-restricted.
This means that the 'wrapper' objects previously used to represent heterogeneous lists will no longer be observable by in-game means.
The NBT file format is unchanged.
Heterogeneous lists are transformed before storage to bypass NBT constraints.
Example transform: ['a', {'b':3}] is stored as [{'':'a'},{'b':3}].
Existing external tools will still be able to read NBT files as before, but heterogeneous lists will be displayed in the transformed form.
No data produced by the game has changed: objects such as Text Components were already producing heterogeneous lists in this form.
Note: these wrapper objects may never be observed in-game, they are only relevant to developers working with the NBT file or network format directly.
Removed the show_in_tooltip field, replaced by tooltip_display component.
This component now always uses its simplified form, with the RGB field inlined to top-level.
e.g. dyed_color={rgb:12345}] -> dyed_color=12345]
The specified color now supports the RGB array format.
e.g. dyed_color=[0.5, 1.0, 0.2]
enchantments and stored_enchantments components
Removed the show_in_tooltip field, replaced by tooltip_display component.
These components now always use their simplified form, with the levels field inlined to top-level.
e.g. enchantments={levels:{sharpness:2}}] -> enchantments={sharpness:2}]
equippable component
Can now apply to saddle slot.
Any mob can now have equipment added in the body slot as long as the component allows it (allowed_entities).
Added new optional field: equip_on_interact (boolean).
If true, players can equip this item onto a target mob by right-clicking it (as long as this item can be equipped on the target at all).
The item will not be equipped if the target already has an item in the relevant slot.
If not specified, defaults to false.
hide_additional_tooltip component
Has been removed and replaced by use of the tooltip_display component and hidden_components field.
The following components previously covered by the hide_additional_tooltip component may need to be hidden:
minecraft:banner_patterns
minecraft:bees
minecraft:block_entity_data
Specifically, Mob Spawner and Trial Spawner block entity data will display the configured mob.
minecraft:block_state
Specifically, the honey_level property will be displayed in the tooltip for any item with this specified.
minecraft:bundle_contents
minecraft:charged_projectiles
minecraft:container
minecraft:container_loot
minecraft:firework_explosion
minecraft:fireworks
minecraft:instrument
minecraft:map_id
minecraft:painting/variant
minecraft:pot_decorations
minecraft:potion_contents
minecraft:tropical_fish/pattern
minecraft:written_book_content
This additionally means that tooltips from the above listed components are no longer restricted to specific item types.
Note: for existing items in a world with the hide_additional_tooltip component, any of the above listed components also present on the same item will be added to the list to hide in tooltip_display.
hide_tooltip component
Has been removed and replaced by use of the tooltip_display component and hide_tooltip field.
jukebox_playable component
Removed the show_in_tooltip field, replaced by tooltip_display component.
tool component
Added new optional field: can_destroy_blocks_in_creative (boolean)
If false, players cannot break blocks while holding this tool in Creative Mode.
If not specified, defaults to true.
trim component
Removed the show_in_tooltip field, replaced by tooltip_display component.
unbreakable component
Removed the show_in_tooltip field, replaced by tooltip_display component.
Some existing components are now also transferred from spawning item to spawned entity:
minecraft:custom_name - any entity.
minecraft:potion_contents - Lingering Potion to Area Effect Cloud.
minecraft:potion_duration_scale - Lingering Potion to Area Effect Cloud.
If not specified or removed, the entity will have no equipment.
e.g. equipment:{chest:{id:'minecraft:diamond_chestplate'}}.
This affects all mobs and armor stands, but players are unaffected.
The data format of saddles has been unified between mobs such as horses and pigs, becoming a new kind of equipment slot (and stored in the equipment.saddle field)
This also replaces the boolean Saddle flag from pigs and striders.
The Saddle dropping on death is now affected by the drop_chances field, as with other equipment slots.
The FallDistance field has been changed from float to double and is now called fall_distance.
The armor and off-hand equipment of players is now also stored in the equipment field.
Although items written into the Inventory using armor and off-hand slot numbers still work.
Pos, Motion, and Rotation values without the correct number of components (3, 3, and 2 respectively) will now be fully discarded, instead of only selecting the specified components.
The SleepingX, SleepingY, and SleepingZ fields have been collected into a single sleeping_pos field.
e.g. sleeping_pos: [I;1,2,3]
Block States in the entity data of arrows, minecarts, block displays, endermen, falling blocks, primed TNT, or piston moving blocks are no longer allowed to be specified as an empty object.

If those components are present on spawning item (like spawn eggs, mob buckets, minecraft:painting, minecraft:item_frame), they will be applied to new entity
Components are currently not restored when spawn egg is picked from existing entity
Added components:
axolotl/variant – one of lucy, wild, gold, cyan, blue
cat/collar – one of 16 dye colors
cat/variant – namespaced id from cat_variant registry
chicken/variant – namespaced id from chicken_variant registry
cow/variant – namespaced id from cow_variant registry
fox/variant – one of red, snow
frog/variant – namespaced id from frog_variant registry
horse/variant – one of white, creamy, chestnut, brown, black, gray, dark_brown

wolf/collar – one of 16 dye colors
wolf/variant – namespaced id from wolf_variant registry
Mob buckets and paintings available in creative menu will now use new variants instead of minecraft:entity_data component.
Custom tooltips for bucket of tropical fish and painting items are now based on new components instead of minecraft:bucket_entity_data and minecraft:entity_data.
Cat and Frog variants are now data-driven.
Added uniform way to define variant selection rules.
Equipment assets
Equipment assets may now define new layer types:
pig_saddle – equipment layer for Pig saddles
strider_saddle – equipment layer for Strider saddles
camel_saddle – equipment layer for Camel saddles
horse_saddle – equipment layer for Horse saddles
donkey_saddle – equipment layer for Donkey saddles
mule_saddle – equipment layer for Mule saddles
skeleton_horse_saddle – equipment layer for Skeleton Horse saddles
zombie_horse_saddle – equipment layer for Zombie Horse saddles
The following textures have been moved to support the use of equipment assets for saddles:
Equipment layers configured to be dyeable will now show if the dyed_color component is present on the item, even if the item is not in the #dyeable tag.
If the selected value comes from a registry and the current datapacks does not provide it, the entry will be silently ignored.
In previous snapshot, unrecognized elements caused the whole item model to be ignored.
Boolean Property
minecraft:component
New conditional model property has been added to condition item model: component
Uses component predicates (like ones used in item predicates) to match item components.
However, instead of encoding them as a map of <predicate type>:<predicate value>, a single predicate is encoded in two fields.
Fields:
predicate – type of component predicate (member of minecraft:data_component_predicate_type registry)
value – predicate-specific value
Loot Functions
toggle_tooltips
Now supports any component id in the toggles map.
Any component specified will be toggled in the tooltip_display component.
Network protocol
The client-bound player_chat packet now contains an index increasing for every message sent to the client.
The index starts at 0 when logging in (or is reset by configuration phase and the login packet).
For every message, the server should increment this value by 1.
If this value updates in an unexpected way, the client will disconnect.
As the protocol requires that every chat packet reaches the client in produced order, the goal is to enable faster detection of missed/reordered chat messages for custom server developers.
The server-bound chat and chat_command_signed packets now contain a checksum byte along with the 'last seen' update.
This is a simple hash of the 'last seen' signatures which should be reconstructed by the server, allowing quicker detection of de-synchronized state.
This can be passed as 0 to disable the check, for compatibility with protocol translation.
New optional fields have been added to block predicates: components and predicates.
Their functionality and format are identical to the fields components and predicates on item predicates, but they operate on block entity components (when present).
When present, components will match exact contents of block entity components.
When present, predicates will match partial contents of block entity components.
Entity predicates
A new optional field was added to entity predicate: components.
When present, predicate will match contents of entity components.
Format:
Map of component type key to matching component values.
A new optional field has been added to entity predicates: predicates.
Its functionality and format is identical to the field predicates on item predicates, but they operate on entity components.
When present, predicates will match partial contents of entity components.
The following entity sub-predicates have been removed and replaced with combination of components predicate and variant entity components:

The field color has been removed from minecraft:sheep sub-predicate.
The stepping_on entity predicate can only evaluate to true if the entity is on ground.
Text Components are no longer stored as JSON wrapped by a string.
The format itself is the same as before, but inlined directly into the outer structure.
For example, the item component minecraft:custom_name="{"text":"Renamed item"}" will become minecraft:custom_name={text:'Renamed item'}.
This includes Text Components passed as arguments to commands such as /tellraw or /title.
For example, /tellraw @s '{"text":"Hello world"}' may become tellraw @s {text:'Hello world'}.
Note: in the case where Text Components are embedded in NBT, no distinction exists between boolean and integer types.
To pass boolean arguments to translations, the string form must be used.
For Text Components with the NBT type and interpret set to true, Text Components will be parsed from the given NBT directly rather than converting to string and parsing as JSON.
Hover Events
The hoverEvent field has been renamed to hover_event.
For the show_text action:
contents field has been renamed to value.
e.g. {action:'show_text',contents:'Hello world'} becomes {action:'show_text',value:'Hello world'}

The text field has been renamed to value.
The contents field has been inlined.
e.g. {action:'show_item',contents:{id:'minecraft:stick',count:2}} becomes {action:'show_item',id:'minecraft:stick',count:2}

e.g. {action:'show_item',contents:'minecraft:stick'} becomes {action:'show_item',id:'minecraft:stick'}
For the show_entity action:
The contents field has been inlined.
The id field has been renamed to uuid.
The type field has been renamed to id.
e.g. {action:'show_entity',contents:{id:[I;0,0,0,0],type:'minecraft:pig'}} becomes {action:'show_entity',uuid:[I;0,0,0,0],id:'minecraft:pig'}
Click Events
The clickEvent field has been renamed to click_event
For the open_url action:
The value field has been renamed to url
The click event will no longer parse if not a valid URI with either https:// or http:// schemes, instead of simply not working.

For the run_command action:
The value field has been renamed to command.
The click event will no longer parse if the command contains disallowed characters, instead of simply not working.

For the change_page action:
The value field has been renamed to page.
The page value now requires a positive integer instead of a string.
e.g. {action:'change_page',value:'1'} becomes {action:'change_page',page:1}
The copy_to_clipboard format is unchanged.
Uniform variant selection
Variants that have spawn rules now use uniform approach for selecting.
Selection process:
Every variant field spawn_conditions that contain a list of entries.
Every entry has a condition and an integer priority.
Conditions for all variants for given entity type are evaluated for position where entity is being spawned.
Entries with priority lower than maximum priority of remaining entries are removed.
The game randomly picks one entry out of remaining ones.
If no conditions are remaining, variant remains unchanged from default.
Entry format:
priority – integer
condition – optional structure
Fields:
type
Additional fields dependent on type.
If field is not present, condition is always true.
