Java Edition 22w12a

22w12a is the second snapshot for Java Edition 1.19, released on March 24, 2022, which adds boats with chests, the warden, along with the darkness effect and swift sneak enchantment, makes leaves waterloggable, and fixes bugs.

Mobs

 * Warden
 * The first fully blind mob.
 * 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.
 * When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
 * 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 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 will not dig back when they're in water.
 * Has health points and does  damage on Normal difficulty, bringing players wearing full netherite armor from full health to  health points.
 * 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.
 * Wardens disable shields when they hit the players with their fists.
 * 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 immune to lava and can float up lava columns very fast.

Non-mob entities

 * Boat with Chest
 * Function similarly to minecart with chests, but in boats instead, so player can take a journey on the water and carry things.
 * Crafted by combining a chest with any boat.
 * Breaking it drops itself (as opposed to a minecart with chest, which splits into its components).

Gameplay

 * Effects
 * Darkness
 * A status effect triggered by the sculk shrieker, causing the player's camera to dim in brightness, thus limiting the vision of players.

 * Added the Swift Sneak enchantment.
 * Has three levels.
 * Can only be applied on leggings.
 * Allow the player to walk faster while sneaking, up to 75% of normal speed at level III.
