It’s time to unleash another vibrant (see what we did there?) Preview and Beta! Today’s release is bringing you new leash mechanics! Now you’ll be able to leash multiple mobs together, and you’ll also be able to leash herds of mobs to boats, chest boats, and even fences. And with the happy ghast in testing already – that means you’ll be able to test leashing a chest boat beneath your happy ghast as you soar through the skies!

For the full list of goodies, browse the changelog below. And as always, we’re keen to get your feedback on these new features at feedback.minecraft.net  , and you can report any bugs at bugs.mojang.com .

Experimental Features

User Interface

• The Jump and Dash bars no longer take precedence over the Locator Bar while inactive in Creative Mode
• Interaction Button in Creative Mode moved up for Touch devices such that it no longer covers the Locator Bar
• Player Dots on the Locator Bar now show correctly while using split-screen
• The item name tooltip is no longer cut off while the Locator Bar is enabled in Creative Mode

Features and Bug Fixes

Leashing Updates

We are expanding the functionality of leads, to make it possible to leash any leashable entity to another leashable entity and by doing so create chains of leashed entities

Elytra

• Using a Firework Rocket to boost while flying with an Elytra now causes leashed mobs to unleash

Leash Knots

• 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

Leashing Entities to Other Entities

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 leash
• 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
• Known issue: When two mobs are connected, it results in the lead being rendered with a erroneous y-axis offset and appearing below one of the mobs

Physics

All leashable entities now behave more naturally when being pulled.

• 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 leashes break has been increased to 12 blocks, except for the Happy Ghast, which has a leash break distance of 16 blocks
• When dragged on the leash, leashed objects will now orient themselves towards the leasher
• The distance between centers of entities bounding boxes, rather than their feet is used to determine the distance between two leashed entities

Rendering

• 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 custom rope layer wrapping around it

Shears

• 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

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. See updated Creator Documentation for more details.
• 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
• Fixed a bug where directional lighting cut out 8 blocks under the water surface while using Vibrant Visuals
• Painting now renders with correct PBR properties, shadows and illumination when using Vibrant Visuals

User Interface

• Bundle UI now correctly disappears when switching Inventory tabs with controller input
• New items and blocks related to the Happy Ghast no longer have a trailing space in their names (MCPE-199213)
• Tapping on the Bundles Tooltip on Touch devices no longer interacts with the UI behind it
• The Text Background Opacity accessibility setting now also affects hotbar tooltips, chat message backgrounds, and leaderboard displays. (MCPE-79331)
• Fixed an issue where only changing the access of PlayStation friends to your world would not be saved when exiting the menu
• To maintain feature parity with the flatworld presets in the Java Edition, the Snowy Kingdom flatworld preset has been updated to use a snow layer instead of a snow block (MCPE-194367)
