Features and Bug Fixes

Blocks

• Fixed bug where an Enchanted Book with Fire Aspect could be used to light Campfires, Candles, and activate TNT (MCPE-100021)

Items

• When using a Lead on an entity the "Attach" prompt is now translated (MCPE-219627)

Leads

• Leashes will now emit their breaking sound from the location of the leash holder, rather than the actor being leashed

Mobs

• Happy Ghast now drops 1-3 experience orbs when killed by a player
• Starting in 1.21.100, we’re gradually enabling engine changes to mob death behavior. This refactor shouldn’t affect gameplay but we’ll monitor for any death-related bugs.

Projectiles

• Projectile tolerance margin is now incremented based on the total time active in the world (MCPE-220496)
  • Previously, projectile tolerance margin was expanded for every flight tick
  • Now, projectile tolerance margin is expanded for every active tick, regardless of projectile travel state

Sounds

• Increased volume of Happy Ghast ride sound

Technical Updates

Biomes

• Updated "minecraft:grass_appearance" component with "grass_is_shaded" variable if true it adds a shading effect to the grass as if there was a roof.

Blocks

• Released the component minecraft:random_offset from experimental for block format versions 1.21.100 or higher
• Fix incorrect destruction particles on blocks that do not have a "minecraft:destruction_particles" component on the base block json definition, it will now fall back to the "minecraft:material_instances" component's definition for that permutation like it used to
• Fixed a crash related to reading incorrect or corrupt json data for animated blocks. Instead we now trigger a content error and prevent the block from animating.

Editor

• Added an optional image field to tooltips for modal tools and property pane components.
• Added 'Mute Music' and 'Mute Game Sounds' toggles to Editor settings pane.
• Added the ability to drag a structure item from the Structure panel to the viewport. This updates the clipboard and activates the paste preview
• Updated the /structure command in an Editor Project to use the Editor Structure repository instead of the level's
• Fixed misaligned icons and image artifacts for block imaged after entering and returning from a test world

Graphical

• Fishing Line: Increased thickness in Vibrant Visuals mode, so that the fishing line does not disappear from TAA
• Reduced the alpha value from 60% to 25% for hurt color overlay on entities to aid in accessibility
• Caustics textures with incorrect dimensions will no longer be loaded; a content error will be issued and the default caustics texture will be used instead

Experimental Technical Updates

API

• Added class ItemBookComponent to beta for interfacing with minecraft:writable_book and minecraft:written_book to change their contents and sign them.
• Added class BookError and class BookPageContentError to beta.

Biomes

• Adding a new server side biome component surface_builder that will combine the components surface_parameters, frozen_ocean_surface, mesa_surface, swamp_surface, capped_surface, and the_end_surface into one component. Each biome can only use one builder type. The component can be used for world generation settings such as foundation material and sea floor depth.
• Added "minecraft:humidity" component with "is_humid" this forces a biome to either always be humid or never humid. Humidity effects the spread chance, and spread rate of fire in the biome.
• Added 'minecraft:partially_frozen' This component will impact the temperature in a frozen biome, causing some areas to not be frozen. Ex: patchy ice, patchy snow.

Jigsaw

• Changed structure definitions folder from worldgen/jigsaw_structures to worldgen/structures.
