Changes

Blocks

Minecraft:Dried Ghast

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

Items

Minecraft: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.

Minecraft:Harness

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

Mobs

Minecraft: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 Minecraft: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 Template:Cd and file name. The reserved JSON names for each group of settings (e.g., Template:Cd) will continue to function as before. Creators can utilize the Template:Cd, Template:Cd, Template:Cd, and Template:Cd 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.

• Updated the appearance of metals for a variety of block textures in Vibrant Visuals.
