Changes

Blocks

Dried Ghast

The rarity is now common, matching its ingredients.
Has been moved from experimental features and is now available during normal gameplay.

Items

Lead

Using a firework rocket to boost while flying with an elytra now causes leashed mobs to unleash.
Entities can now be leashed to a pre-existing leash knot by interacting with it.
Players can retrieve entities tied to a leash knot by interacting with it.
Shears can now be used to remove leash knots.
Any leashable entity can now be leashed to any other leashable entity.
- To leash an entity to another entity, the player must:
  - Have the entity already leashed to themselves.
  - Sneak and interact with the target entity while holding the lead.
- Leashed entities can now be "stolen" by leashing them again, transferring ownership to the player.
- If re-leashing an entity would result in immediate leash snapping due to distance, the re-leashing cannot be done.
- To prevent erratic behavior when leashed to each other, llamas that are leashed no longer attempt to form caravans.
- A leashed entity cannot be leashed to itself.
- Baby mobs can only be leashed one way - to another entity; they cannot have other mobs leashed to them.
When leashed to a happy ghast, horses, camels, donkeys, mules, boats, chest boats, and sniffers now adjust their position gradually over time, aligning smoothly with their leash holder when suspended mid-air.
In all other cases, entities align to the direction they are being pulled and no longer behave erratically when suspended mid-air.
Mid-air friction now applies to Boats just like any other entity, meaning they can no longer orbit the player or behave excessively bouncily.
The distance at which leads break has been increased to 12 blocks, except for the happy ghast, which has a break distance of 16 blocks.
When the lead is pulled, leashed objects will now orient themselves towards the player who has the lead.
The distance between centers of entities bounding boxes is used to determine the distance between two leashed entities.
Boats and large leashable mobs that cannot fit in a boat (horses, donkeys, mules, camels, and sniffers) when leashed to a happy ghast are rendered with four leashes instead of one.
- In this configuration, the happy ghast also features a rope layer wrapping around it.
Shears can now be used on leashed entities to unleash them, removing both incoming and outgoing leash connections.
Players cannot cut other players' leashes.
Dispensers can now use shears to unleash leashed entities.

Harness

Has been moved from experimental features and is now available during normal gameplay.

Mobs

Happy Ghast

The happy ghast now turns more smoothly.
Harness goggles will now always be down as long as the harnessed Happy Ghast has at least one mounted player.
Has been moved from experimental features and is now available during normal gameplay.

General

Graphical

Made Vibrant Visuals the default graphics mode for supported devices.
Added the ability to data-drive some of the Vibrant Visuals / Deferred Graphics related settings per biome. Creators can provide multiple versions of atmospherics, color grading, lighting and/or water configurations as long as each has a unique identifier and file name. The reserved JSON names for each group of settings (e.g., lighting/global.json) will continue to function as before. Creators can utilize the minecraft:atmosphere_identifier, minecraft:color_grading_identifier, minecraft:lighting_identifier, and minecraft:water_identifier in Client Biome JSONs to connect particular rendering settings to a given biome. Note that certain parameters, such as tone mapping operators, caustics and wave simulation on/off cannot be customized per biome at this time. Parameters will be spatially blended as players move between biomes.
Increased back-scattering of light underwater in Vibrant Visuals.
Cloud shadows no longer pop in and out of view when looking around using Vibrant Visuals on Android devices.
Painting now renders with correct PBR properties, shadows and illumination when using Vibrant Visuals.
Added MERS texture support for signs in Vibrant Visuals.
Added new texture assets for a variety of trims, particles, spawn eggs, water and the dark oak boat in Vibrant Visuals.
Updated the appearance of metals for a variety of block textures in Vibrant Visuals.
Updated the cave vines, chorus flower, pumpkin, fire fly bush and a variety of other plant textures in Vibrant Visuals.
Updated the bee, dolphin, ghast, pig saddle and strider textures in Vibrant Visuals.
