1.21.2, the release of Bundles of Bravery, is a game drop for Java Edition released on October 22, 2024.^[1]

It adds bundles, more banner patterns to match Bedrock Edition, and reorganizes rarity to better reflect gameplay. In addition, it introduces Winter Drop features to experimental gameplay, including the pale garden and the creaking, as well as new data components that grant more options for item customization.

Banner patterns

• Two new banner patterns have been added to achieve parity with Bedrock Edition:
  • 👁 Image
    Field masoned banner pattern
  • 👁 Image
    Bordure indented banner pattern

👁 Image
Bundle

• A new item that can hold a mixed stack of up to 64 items.
• Crafted from a string and a piece of leather.

• Can be dyed into 16 colors. Once dyed, the color can not be reset to default.^[2]

• Items that stack up to 16 take up more space, while items that do not stack take up the entire bundle (except other bundles).
  • Shulker boxes can not be placed in bundles.
  • Bundles can be placed in other bundles; this takes up 4 slots plus the number of slots already used by the inner bundle.
• Has a tooltip that shows the items inside.
  • If a bundle has less than 8 item types inside, the tooltip shows all of them.
  • Otherwise the tooltip shows the top 3 rows of items and the others are hidden below, always showing at least 12 item types.
• When holding a bundle in hand, the player can throw out one group of items onto the ground by pressing use.
• It is possible to select any of the visible items to pull out of the bundle.
  • Pressing use takes the selected item, or the first item if nothing is selected.
  • Using the scroll wheel selects a different item.
  • When selecting an item to remove, the bundle icon shows that item poking out of the bundle.

Sounds

• Added unique break, fall, hit, place, and step sounds for monster spawners.

Experiments

• Added the Minecart Improvements, Redstone Experiments, and Winter Drop experimental data packs.

Languages

• Added support for High Norwegian.

Options

• Added new video setting "Reduce FPS when" that controls when the game limits its maximum frame rate.
  • Options include：
    • AFK: FPS limited to 30 if the game hasn't received input for 1 minute, and further limits FPS to 10 after 9 minutes. Also limits FPS to 10 when the game is minimized.
    • Minimized: Only limits FPS to 10 when the game is minimized.
  • Defaults to AFK.
• Added new accessibility setting "Increase block outline contrast" that increases the contrast of the outline shown on blocks.

Loom

• Now requires field masoned banner pattern and bordure indented banner pattern to craft corresponding banners.

Nether portal

• The powered models have changed to include the updated redstone torch textures and models.

Slime blocks

• Now cancel fall damage when sneaking.

Banner patterns

• Added unique item textures for each banner pattern.
• Each banner pattern item now includes their pattern in their name instead of as a subtitle.

Bee nests and beehives

• Now show information about their honey level and number of bees in their inventory tooltip.
• Now use their "full" texture when held or in the inventory, and they are at max level of honey.

Bundle

• No longer experimental.

Ender pearl

• Thrown ender pearls now load and tick chunks around them in a 3x3 chunk area.
  • Now ensure that the chunk they are in or travel into is always loaded and ticking.
  • An ender pearl creates a ticket for chunk loading any time it moves into a new chunk, and also periodically every 10 seconds.
  • They also load chunks when crossing to a new dimension, so that they can always continue to travel.
  • This ensures that ender pearls can always land, and makes cross dimensional ender pearl traveling more predictable.
  • Now unload when a player logs out, and reappear whenever that player logs back in, similar to how mounts currently behave.

Milk bucket

• Drinking a milk bucket in Creative mode no longer gives the player an empty bucket.

👁 Image
Minecarts

• Minecarts articulate their movement better when going fast, riding on the rail all the time.

  • Defaults to 8 and goes up to 1000 blocks per second.
  • Setting it to a specific value does not guarantee that a minecart reaches that particular max speed - there are built in air resistances and similar effects that the speed added through slopes or powered rails need to overcome.
  • This gamerule only exists in worlds with the experiment Minecart Improvements enabled.

Options

• Added a new accessibility setting that makes players follow the rotation of minecarts they ride.

  • Is active during night and dormant during day.
• Sends a trail of particles toward the connected creaking when the creaking gets hit by the player.
  • Particle speed is affected by the distance of the creaking from the heart block.
• Mining the block is most efficiently done with an axe, but it only drops when using a Silk Touch tool.
  • When creaking heart block is destroyed, the connected creaking is removed.
• A redstone comparator that is attached to the creaking heart block outputs a signal strength dependent on the distance to the connected creaking.

Boats and boats with chests

• The entity IDs for boats and boats with chests have been split into separate types, one per existing variant, instead of Type field.

/ride

• No longer makes players ride leash knots, lightning bolts, and fishing bobbers.

Data components

• Re-arranged the priority of item stack components that modify the name of the item in the following way:
  • The [NBT Compound / JSON Object] title field in the minecraft:written_book_content component (the highest priority)
  • The minecraft:custom_name component

• Is now always present on every item.

minecraft:lock​^{[more information needed]}

• Has been changed to the following format:

Particles

    • minecraft:dust_color_transition.from_color (previously accepted only vector of floats).
    • minecraft:dust_color_transition.to_color (previously accepted only vector of floats).

Raw JSON text

• Invalid selector patterns in chat components now cause commands to fail to parse, instead of resolving to an empty string.

• The pack format version is now 57.

    • This allows for easier customization of Trial Spawner configurations in data packs.
    • Inlined configuration data is still supported.
  • Entities' rotation on the x axis is now clamped between -90 and 90.
  • /loot command now returns an error when trying to drop from a block without a loot table (like air).
  • Removed the bundle feature flag and built-in datapack.

  • Now trigger whenever an arrow kills an entity, not just when fired from a crossbow.
  • Has a new optional item predicate field, fired_from_weapon.
    • Can be used to match the item used to shoot the arrow.

Enchantments

Loot tables

• Special loot table empty has been removed and is no longer defined in vanilla data pack.
• Sheep now always uses a single loot table entities/sheep.
• Wool drops are still defined in sub-tables in entities/sheep/<color>, but they are now just dispatched from the main table.
  • Note: mutton drop is now controlled by the main table, while sub-tables are responsible only for wool drop.

Recipes

• The crafting_special_suspiciousstew recipe type has been removed.
• The format used for recipe ingredients has been simplified and aligned with other fields that accept item lists (like item predicates):
  • For items: { "item": "<item id>" } now becomes "<item id>".
  • For tags: { "tag": "<tag id>" } now becomes "#<tag id>".
  • Lists of items are still allowed, but tags can no longer appear in such list.

  • For leggings textures, the _leggings suffix is dropped.

Shader program configurations

• Can now specify preprocessor define directives to be injected into the shader source, which can be referenced in the shader
  • In the vanilla assets, this is used to combine multiple shaders into one program. For example, rendertype_cutout, rendertype_solid, rendertype_cutout_mipped, rendertype_transluscent and rendertype_tripwire now use the terrain.fsh / .vsh shaders. Define directives are used alongside an #ifdef ALPHA_CUTOUT statement in the terrain.fsh program to control if the shader program should discard transparent pixels.
  • These can be specified in a new defines object in the root of the shader json file

• The blend field has been removed, as it had no use
• The attributes field has been removed, instead the Position attribute is always bound
• The vertex and fragment shader references in program definitions are now namespaced ids
  • A vertex shader <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.vsh
  • A fragment shader <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.fsh

Uniforms

• The ChunkOffset uniform in terrain shaders has been renamed to ModelOffset

  • #moj_import <<namespace>:<shader program>> resolves to assets/<namespace>/shaders/include/<shader program>
• Relative imports are not namespaced and behave as before

Post-processing effects

• Post-processing effect configurations have been moved from assets/<namespace>/shaders/post to assets/<namespace>/post_effect
• Vertex and fragment shaders used by post-processing effects have been moved from assets/<namespace>/shaders/program to assets/<namespace>/shaders/post.
• The format of post-processing effect configurations have been updated.
• name has been renamed to program, and is now a namespaced id of a shader program configuration.
  • <namespace>:<path> resolves to assets/<namespace>/shaders/<path>.json.
• intarget and auxtargets have been merged into a single inputs list, as specified by the input format below.
• outtarget has been renamed to output with the same format.
• targets is now a map between target name and target definition, as opposed to a list
  • Inline target names are replaced with an empty object
    • For example, ["swap"] becomes {"swap": {}}
  • Target definitions with a specific size remain the same, with the name field moved into the map key
    • For example, [{"name": "potato", "width": 16, "height": 16}] becomes {"potato": {"width": 16, "height": 16}}

Inputs

• For both render targets and texture inputs, the following fields may be specified:
  • [String]  sampler_name The prefix to set up both _Sampler and _Size uniforms.
  • [Boolean]  bilinear (default: false) If true, the input is sampled with a bilinear filter. For render targets, this replaces the removed use_linear_filter field on the pass definition.

• For inputs from a render target, the following fields may be specified:
  • [String]  target The render target id, a namespaced id. Either a custom target id defined in the same file, or minecraft:main to reference the main screen target. This replaces the former id field, which was a free-form string.
  • [Boolean]  use_depth_buffer (default: false) Set to true to sample from the depth texture, false to sample from the color texture. This replaces the former :depth suffix applied to the target id.

• For inputs from a static texture, the following fields may be specified:
  • [String]  location The location to a static texture file that can be sampled by the effect. As the id field did before, this resolves to a texture at assets/<namespace>/textures/effect/<path>.png
  • [Int]  width Width of the texture in pixels, must be a positive integer.
  • [Int]  width Height of the texture in pixels, must be a positive integer.

External inputs

• The 'Fabulous' graphics transparency post-processing config no longer specifies the sorted framebuffers as custom targets.
  • These are instead imported in the same way as the minecraft:main target.
  • translucent, itemEntity, particles, weather, clouds are now minecraft:translucent, minecraft:item_entity, minecraft:particles, minecraft:weather, and minecraft:clouds respectively.
• The entity outline processing shader similarly imports the minecraft:entity_outline target

Core shaders

• Some core shaders now share the same shader programs.
  • The rendertype_clouds shader no longer gets the cloud texture sampler.
  • The rendertype_cutout, rendertype_solid, rendertype_cutout_mipped, rendertype_transluscent and rendertype_tripwire shaders now use the terrain.fsh and terrain.vsh programs.
  • The rendertype_armor_cutout_no_cull, rendertype_breeze_wind, rendertype_energy_swirl, rendertype_entity_cutout_no_cull_z_offset, rendertype_entity_cutout_no_cull, rendertype_entity_cutout, rendertype_entity_no_outline, rendertype_entity_smooth_cutout, rendertype_entity_solid, rendertype_entity_translucent_emissive, rendertype_entity_translucent and rendertype_eyes shaders now use the entity.fsh and entity.vsh programs.
• Most UI elements such as buttons, the inventory, menu backgrounds, the hotbar, etc are now rendered with position_tex_color instead of position_tex

Data components minecraft:potion_content

• Added [String] custom_name field.
  • Used to generate the name of the item. The game uses the translation key item.minecraft.<item type>.effect.<value>.
  • This name has a higher priority than the minecraft:item_name component, but lower than the minecraft:custom_name component.

Enchantments

  • Snowballs
  • Tridents
  • Small fireballs

  • Fields:
    • sheared - optional boolean.
    • color - optional wool dye color.

• Trim textures are loaded from the appropriate folder in the textures/trims/entity directory.
  • For example, armor with wolf_body layers fetch trims from textures/trims/entity/wolf_body

• The pack format version is now 42.
• Removals and renames of some deprecated translations is now automatically applied at startup.
  • Packs that used those translations need to re-add them manually.

• The texture map for the arrow and bee stinger models have been updated.
• The model and UV mapping of the Dragon Egg have been updated.
• The tooltip background and frame may now be customized by replacing sprites:

  • Items with a custom tooltip_style component uses sprites with IDs:
    • <namespace>:tooltip/<path>_background and <namespace>:tooltip/<path>_frame
• The nine_slice GUI sprite scaling mode has a new optional boolean (true or false) property: stretch_inner
  • If true, the inner parts of the texture (i.e. not the corners) are stretched instead of tiled
  • If not specified, defaults to false as before.
• The appearance of a highlighted slot can now be customized by replacing sprites (this supports the use of animated textures):
  • container/slot_highlight_front: The sprite to render in front of highlighted slots.
  • container/slot_highlight_back: The sprite to render behind highlighted slots.
• Likewise, the appearance of a highlighted item within the bundle can be customized with the following sprites:
  • container/bundle/slot_highlight_front.
  • container/bundle/slot_highlight_back.
• The appearance of highlighted items has been updated to improve visibility of the item.
• The models and UV mapping related to the torch and blocks containing redstone torch have been updated.
  • The "inverted" model now uses 6 separate faces creating the same effect as a model with a negative size.
  • The UV layout for the inverted model was updated.
• Added texture and sound for tweaked air bubble UI.
  • New texture added for empty air bubble.
  • Sound added for when air bubble pops.

  • The model definition is an object with fields: wolf_body, horse_body, llama_body, humanoid, humanoid_leggings, wings
    • All fields are optional, and can be used to specify a list of layers for the given model layer type
    • Each field contains list of layer objects:
      • texture: namespaced texture location for this layer
        • namespace:path resolves to assets/<namespace>/textures/entity/equipment/<layer_type>/<path>.png
      • dyeable: object with fields (optional), specifying how this layer behaves when dyed (in the dyeable item tag, and has dyed_color component)
        • color_when_undyed: RGB color integer (optional)
        • If specified, this layer is tinted by the color contained in the dyed_color component
          • If the item is not able to be dyed or is not currently dyed, then it is tinted based on the color specified by color_when_undyed
          • If color_when_undyed is not specified and the item is not dyed, the layer is hidden
      • use_player_texture: boolean (default: false), true if this layer texture should be overridden by a texture given by the player

  • This is controlled by a non-negative ordering index that is sorted highest to lowest.
• The client now shares the state of the 'Particles' limiter option to be used by custom servers.

Hardcore

• Hardcore is now implemented properly in the server software.
  • Prior to this, the hardcore option in server.properties only controlled whether the player can respawn after death. It could be changed independently the world's hardcore mode (set on the world creation screen), which only controlled whether the client is informed hardcore mode is enabled on the server (which in turn decided on the hearts texture and death screen) and forced hard difficulty.
  • The world's hardcore mode is now used for controlling whether the player can respawn, informing the client that the server is hardcore mode and forcing hard difficulty.
  • The hardcore option in server.properties is now only used for enabling the world's hardcore mode during world generation.

server.properties

• Added the option pause-when-empty-seconds.
  • When set to a positive value, causes the server to pause when no player has been online for that many seconds.
  • Defaults to 60.
