 * Dripleaf
 * Allows an entity to stay on it for 1.5 seconds (30 ticks), before the entity will fall through it.
 * The tilt happens in 3 stages: Unstable, Partial, and Full. These can be seen in the F3 debug menu.
 * All the stages are solid except the Full stage, which is when the player falls through.
 * When nobody is standing on it, it is set to None stage.
 * The tilt can also be triggered by hitting the plant with a projectile.
 * The tilt can be prevented by powering it with redstone, but hitting it with a projectile still tilts.
 * Comes in two sizes: Small and Big. Small can be applied bone meal to grow into Big.
 * Small dripleaf can only be obtained with shears (otherwise breaks), and can only be planted on clay, or underwater on clay and dirt blocks.
 * Big dripleaf can be obtained with any tool or by hand, and can be planted on grass and dirt blocks.

 * Can be combined to form longer stalactites and stalagmites.
 * Thrown tridents break pointed dripstone, which also breaks when pushed directly or with a block by a piston.
 * Stalagmites break if not attached to something below
 * Stalagmites hurt entities that fall on top of them more than normal fall damage.
 * Damage is relative to height: For example, jumping on a stalagmite deals of damage, and falling from 3 blocks deals  of damage.
 * Stalactites can fall or break if unsupported, and break apart on impact, hurting entities they fall on.
 * Damage is relative to height: For example, one falling from 2 blocks deals of damage, and one falling from 3 blocks deal  of damage.
 * They drip water or lava into cauldrons if a source block is placed above the stalactite, and gradually fill the cauldron. Water drips even without any water above the block (lava in the Nether), but does not fill the cauldron.


 * Powder Snow
 * A variant of snow, Entities that walk over it sink into it.
 * Leather boots can be worn to prevent entities from sinking into powder snow blocks.
 * Players can still crouch to descend with leather boots. Wearing leather boots also allows powder snow to be "climbed", like water or scaffolding.
 * When inside a powder snow block, a frosty vignette appears around the player's screen and any entity inside starts freezing and taking damage after a short time.
 * Wearing any piece of leather armor stops the freeze effect.
 * Can be collected and placed with a bucket.


 * Rooted Dirt
 * Decorative blocks.
 * A dirt-like block with roots on its texture.
 * Similar to coarse dirt, neither mycelium nor grass spread to it.


 * Sculk Sensor
 * A redstone component that sends and receives redstone signals wirelessly.
 * Currently, it does not generate naturally, available only from the Creative inventory or commands such as, but natural generation is planned for future versions.
 * Senses vibrations such as block placement, footsteps, and projectiles, and emits a redstone signal.
 * Vibration JE1 BE1.gif Emits particles when it senses a vibration nearby.

 * It follows and attacks players, mobs, and other entities that make vibrations.
 * It does not attack other Wardens.
 * When attacked, it path finds toward the player.
 * Seems to follow the same rules as the sculk sensor when detecting noise.
 * 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 the Warden, the mob inspects the location where the projectile landed, due to the projectile creating movement and noise. This feature can be used in order to cause a distraction.
 * Does not detect players that are sneaking.
 * Can detect players that are invisible.
 * When aggravated for long enough, the warden follows the player continuously, regardless of any other distractions.
 * Incredibly strong, doing damage, bringing players wearing full netherite armor from full health to  health points.

 * The core creates a low throbbing sound as it pulses. The sound and animation seem to speed up rapidly when the warden notices a player.
 * 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).

World generation

 * Caves
 * Added new noise caves, which come in two types: "cheese" and "spaghetti" caves.
 * Added flooded aquifer caves.
 * The old "carver" cave generation still generates, combining with the new caves.


 * Cheese caves
 * Often form caverns of various sizes.
 * Utilize noise generators for generation.
 * Can form cave entrances when they intersect with land.


 * Spaghetti caves
 * Long, narrow caves.
 * Utilize noise generators for generation.
 * Can form cave entrances when they intersect with land.


 * Aquifers
 * Used to generate bodies of water in new caves.
 * Currently only used below Y=31, meaning any noise caves between Y=31 and Y=63 are flooded with water. This will be fixed in a later snapshot.
 * Magma blocks may generate at the bottom of these new water bodies, creating downward bubble columns.
 * Replaces the old underwater cave carvers/canyons.
 * Fish spawn in aquifers if it is under an ocean or river.


 * Amethyst Geodes
 * A new feature found uncommonly underground (can rarely appear exposed to the surface close to sea level).
 * Contains blocks of amethyst and budding amethyst blocks, which are encased in a shell of calcite and smooth basalt (previously calcite and tuff).
 * Also generates with a small air pocket nearby which may open into the geode.
 * Generally generates at or below sea level (y = 63).
 * Most commonly generates at lower levels (y = 0 to y = 40)
 * Overrides standard caves and ravines, but is overridden by abandoned mineshafts.
 * Currently has a high generation rate, presumably for testing purposes which was also done with ruined portals before.


 * Dripstone Caves
 * A new underground cave biome, consisting of a massive cave biome containing vast quantities of stalactites and stalagmites.
 * Made up of primarily dripstone blocks and stone, with large clusters of dripstone blocks hanging from the ceiling, pointed dripstone on the floor and ceiling and many pools of water.
 * Does not yet generate naturally in normal worlds, and can be generated only using buffet worlds with "Dripstone Caves" selected as the source biome or using custom world. Natural generation is planned for future versions.


 * biome
 * New biome at the "deepest depths of the world".
 * Wardens can spawn here.
 * Contains sculk blocks and sculk sensors.
 * Contains Deepslate.
 * Likely generates within the Deepslate layer between -1 Y and -64 Y.
 * Presumed to contain candles.


 * Generate below azalea trees.
 * Can be reached by following hanging roots underground.
 * Contains tall grass, glow berries, big and small dripleaf plants, spore blossoms, moss blocks, moss carpets, clay blocks, hanging roots, rooted dirt, and azalea variants.
 * Can spawn axolotls.
 * Can spawn axolotls.


 * Seems to be possibly a large tunnel-like cave generation.
 * Not much is known about this cave variation yet, but it was confirmed on Twitter by Henrik Kniberg.
 * Possibly contain "catacomb" style branching cave sections.
 * Possibly contain "catacomb" style branching cave sections.


 * More extreme and smooth terrain.
 * Likely change to the generation of alternate stone types, to make them appear in larger but less numerous deposits.
 * Possibly seen in a screenshot tweeted by Henrik Kniberg, in which diorite appears to generate in a long and flat horizontal strip, rather than a small unevenly shaped patch.
 * Ore generation will see further rebalancing and will influence the surrounding stone
 * Ore generation will see further rebalancing and will influence the surrounding stone

Gameplay

 * The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.
 * Possible items shown in the preview footage include:
 * Ceramic shards of varying color that depict different images.
 * Diamond blocks and emerald blocks are probably not a part of this list and serve as a placeholder for something else.
 * Diamond blocks and emerald blocks are probably not a part of this list and serve as a placeholder for something else.


 * While in the deep dark cave biome, the ambient lighting occasionally dims temporarily, limiting the player's visibility. This serves as a warning that the warden is nearby.

World generation

 * Mineral veins
 * Some stone appears a little different and when that stone is mined, more ore should be found behind it.


 * Other Stones
 * Diorite or calcite and what appears to be tuff spawn in layers of stone in straight lines instead of splotches.

Structures

 * Underground Cabin
 * Seen in the Deep Dark biome during the Minecraft Live 2020 stream.
 * Consists of a chamber with a cobblestone floor and stripped log support beams, containing 3 barrels, a blast furnace, and a large chest, with cobwebs and candles in and around it.
 * May possibly not be a generated structure, but instead a construction built for the purpose of the Warden showcase.

Trivia

 * This is the first Bedrock Edition update to add a new ore to the overworld since emerald ore was added.
 * Similarly, this is also the first Bedrock Edition update to add a real-world metal into the game since iron and gold ore was added.
