 * Sculk Catalyst.png Sculk Catalyst
 * Generates in the deep dark biome.
 * Emits soul particles after a mob dies within 8 blocks, and grows sculk related blocks.
 * Spreads sculk blocks to wherever a nearby mob dies. The amount it spreads depends on the amount of experience the mob is meant to drop.
 * Even if the mob doesn't drop experience as it wasn't killed by a player, the blocks would still spread based on the amount of experience it normally drops.
 * Experience does not drop in these cases.
 * The charge decays over time, faster the furthest away from the catalyst it moves.
 * If a charge decays more than 4 blocks away from the catalyst, it has a chance of creating either a sculk sensor (90%) or a sculk shrieker (10%).

Mobs

 * Allay.png
 * Voted to be in the update during Minecraft Live 2021.
 * Can find dropped blocks or items for a player, collecting the same items from the world as it holds in its hand.
 * Picks up dropped items in loaded chunks and can carry up to a stack at a time, and cannot duplicate items or take items out of chests. It drops its collected items when in range of a note block.


 * If holds an item it got from a player, it follows that player, up to a distance of 64 blocks away.
 * It can be made to hold an item by interacting with the allay (pressing ).
 * The item can also be removed by interacting with the allay (pressing ) while with an empty hand.
 * Able to drop items at nearby note blocks, and stay close to a note block that has been played near them.
 * When playing a note block near them, that note block becomes their favorite one for 30 seconds, and they attempt to drop off items at the note block rather than at the player.
 * Connecting with note blocks is visualized by the vibration particle.
 * Connecting with note blocks can be blocked by wool, by placing wool between the allay and the note block.
 * If they have items in their inventory, they attempt to give them to their owner.
 * Sometimes spawn in cages next to pillager outposts (similar to iron golem), and inside woodland mansions.

 * Warden JE1 BE1.png Warden
 * The first fully blind mob (bats have basic eyesight, both in-game and in the real world).
 * Because of this, it stumbles as it walks.
 * Has a sense of smell. It can detect and pathfind toward the general location of a player or mob through a "smelling" action.
 * Prioritizes smelling the player or mob that it is most suspicious of, rather than the one closest to it.
 * Has a sense of vibration. When sensing movement, it pathfinds toward the source of the movement.
 * It follows and attacks players, mobs, and other entities that make vibrations.
 * It does not attack other wardens.
 * When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
 * Seems to follow the same rules as the sculk sensor when detecting vibrations.
 * If any projectile (e.g. egg, snowball, arrow) lands near it, the warden inspects the location where the projectile landed, due to the projectile creating significant vibrations. This feature can be used in order to cause a distraction.
 * Does not detect players that are sneaking.
 * Can detect players or mobs that have the Invisibility effect.
 * Becomes more suspicious of a player or mob as it detects its location more through vibrations and/or smelling. When it suspects the target enough, it identifies its exact location, which aggravates it, causing it to pathfind toward the target to attack regardless of outside distractions.
 * Spawns in the deep dark biome, specifically when a player activates sculk shriekers three times.
 * It is the only mob that spawns in the deep dark biome.
 * "Emerges" from the ground when spawned by sculk shriekers.
 * Digs back into the ground when it doesn't sense any vibration after 60 seconds.
 * Like how name tags prevent despawning, name tags can also prevent wardens from being able to burrow back to the ground.
 * Wardens do not dig back when they're in water.
 * A mob designed to be extremely difficult, intended to be avoided and fled from.
 * Has health points and does  damage on Normal difficulty, bringing players wearing full netherite armor from full health to  health points. Wardens also disable shields when they hit the players with their fists, and are at least as fast as a walking player. (More health than a wither  except in BE, hard mode, where Wither HP = )
 * The warden doesn't qualify as a target for the advancement "Monster Hunter" and isn't needed to receive the advancement "Monsters Hunted" due to its role.
 * Warden's chest has a glowing core that appears to brighten and dim in tandem with the Darkness effect.
 * The core creates a low throbbing or "heartbeat" sound as it pulses. The sound and animation speed up rapidly as the warden gets more suspicious of or closer to attacking a player or mob.
 * Is about 3.5 blocks tall, making it one of the tallest mobs in the game, exceeding the iron golem and enderman in height and width (the same).
 * Wardens have long melee reach, being able to hit the player when on top of a four block pillar, thus making it capable of countering certain cheese tactics, such as pillaring.
 * Can charge a ranged attack when the player is building high, hiding behind walls or being out of range of their melee attack.
 * Their rib cages open up to shriek a sonically charged ranged attack that can penetrate walls and bypasses shields and armor (including the damage reduction by armor enchantments such as Protection).
 * The ranged attack deals damage in Normal and can hit at a horizontal distance of 15 blocks.
 * The ranged attack can hit only one target at a time.
 * Is immune to lava and knockback, and never slows down in water.

General

 * Chat
 * Chat messages between players, as well as chat from the, , , and commands, are now cryptographically signed.
 * Players are given a Mojang provided key-pair on startup.
 * Chat styling is now handled via server resource packs with the translation key.
 * Servers can now define different chat style formats for clients, which can now be controlled by the server through the registry (found under the worldgen folder in the vanilla report).
 * These are synchronized to clients when they join the server.
 * The translation key or translation format can be defined, like or.
 * Chat can be similarly optionally narrated with a custom translation key or format.
 * The entire message can have formatting applied, such as italics or a specific color (but currently not click or hover events).
 * Servers can now enable chat preview, which displays a server-controlled preview above the chat edit box, showing how the message appears when sent.
 * Can be used by servers to preview messages with styling applied, such as emojis or chat coloring.
 * Chat preview sends chat messages to the server as they are typed, even before they're sent.
 * The server then sends back the styled preview in real time.
 * This allows servers to apply dynamic message stylings while still allowing chat to be securely signed.
 * Chat preview is also shown for chat-related commands, such as and.
 * A warning toast message is shown on the client when joining a server with chat preview, and it can be globally disabled in chat settings.
 * Dynamic chat styling can also be controlled by the server, although this is signed only when chat preview is enabled.

 * Data pack and resource pack
 * Can have section in pack.mcmeta now.
 * This section has mandatory field, which is a list of patterns (regular expressions) for namespaces and paths.

 * section does not apply to a pack containing it, only to packs loaded before it.
 * Both and  can be omitted: if they are, the game works as if they had been specified as a ".*". Missing field matches every value. When they are included, these fields contain a regular expression pattern.
 * For example, adding pack with this section in pack.mcmeta after vanilla pack hides all recipes and advancements defined by vanilla pack:
 * World presets/types and super flat world presets in “Create World” screen can now be controlled by datapacks.
 * New registry types were added to data-drive presents (like "Amplified" or "Single Biome").
 * New registry types were added to data-drive presents (like "Amplified" or "Single Biome").

 * This option is best experienced with headphones.
 * Toggled off by default.
 * Added "Chat Preview" chat option, for enabling chat preview.
