Blocks

 * Copper Block


 * Can be crafted with 4 copper ingots, and can also be crafted back into 4 copper ingots.
 * Oxidizes and changes texture to a turquoise-green over time.
 * Can be stopped from oxidizing by combining it with a honeycomb to create a Waxed Copper Block.
 * Can be crafted into cut copper.


 * Copper Ore
 * Generates randomly underground in small veins, but this has been confirmed to be a placeholder.
 * Has the same rarity as iron.
 * Generating starts at the same minimum level(s) as iron.
 * Can be smelted into a copper ingot.
 * Spawns in up to 5 blocks together.


 * Cut Copper
 * Can be made into stair and slab variants.
 * Oxidizes and changes texture over time.
 * Can be stopped from oxidizing by combining it with a honeycomb to create Waxed Cut Copper.


 * Cut Copper Slab
 * Oxidizes and changes texture over time.
 * Can be stopped from oxidizing by combining it with a honeycomb to create a Waxed Cut Copper Slab.


 * Cut Copper Stairs
 * Oxidizes and changes texture over time.
 * Can be stopped from oxidizing by combining it with a honeycomb to create Waxed Cut Copper Stairs.


 * Dripstone Block
 * A decoration block.
 * Appears to be made of the same materials as stalactites and stalagmites but as a full cube.
 * Only generates in the Dripstone caves biome which is currently only available through single biome, caves, or floating islands world types.
 * Can be crafted from 4 pointed dripstone.


 * Lightning Rod


 * Can be crafted with 3 copper ingots.
 * Lightning strikes within a 32-block radius get redirected to the lightning rod.
 * Gives off a redstone signal with a strength of 15 if hit by lightning.
 * Can be activated directly by throwing a trident with Channeling at it during a thunderstorm, though this does not produce a redstone signal.
 * Gives a light level of 1.


 * Pointed Dripstone
 * Can be either placed on a ceiling to create a stalactite, or on top of a block to create a stalagmite.
 * Can be combined to form longer stalactites and stalagmites.
 * Thrown tridents break pointed dripstone. Will also break when pushed directly or with a block by a piston.
 * Stalagmites break if not attached to something below
 * Stalagmites hurt entities which 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
 * Now available in-game.
 * A variant of snow, Entities that walk over it will 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 will stop the freeze effect.
 * Can be collected and placed with a bucket.


 * Sculk Sensor
 * A redstone component that sends and receives redstone signals wirelessly.
 * Currently, it does not generate naturally, only available 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.
 * Particle of the Vibration.gif Emits particles when it senses a vibration nearby.
 * A comparator connected to it will emit different signal strengths based on what caused the signal.
 * Does not detect ambient weather such as rain.
 * Wool blocks between the sensor and the cause of the sound prevent the sensor from detecting the sound.

Items

 * Bundle


 * Crafted with 2 string and 6 rabbit hide.
 * Used to store other items (except shulker boxes) inside of it.
 * Can only hold a stack of items, but is able to hold different types of items inside of it.
 * Items with smaller stacks, such as ender pearls, take up more room in a bundle, and non-stackable items take up the whole bundle.
 * The bundle's contents can be opened by pressing while holding it, throwing out its entire content into the world. When destroyed as an entity, it drops the items it currently has as well.
 * Right-clicking a bundle in the inventory empties one item from the bundle.
 * Even though bundles are not stackable, bundles can be nested.
 * Can hold up to 16 bundles.
 * Only empty bundles can be placed in other bundles without using commands.
 * Has a GUI when hovering over it.
 * Shows contained items in its GUI's inventory slots when hovering over it, as well as fullness as a number.
 * Note: Bundles can hold any amount of any item if added using commands.


 * Copper Ingot
 * Obtained by smelting copper ore.
 * Used to craft copper blocks and lightning rods.


 * Powder Snow Bucket


 * Obtained by using a bucket on powder snow.
 * Can be used to place a powder snow block wherever it is used, or can be used to fill cauldrons with powder snow.


 * Spawn eggs

Mobs
Goat


 * Spawns in mountain biomes.
 * Can jump high to avoid obstacles, about 5 blocks tall.
 * Attacks nearby animals by charging and knocking them a considerable distance.

 * Can be bred with wheat, which produces a baby goat.
 * Drops one goat horn when ramming into a block. Goat horns do not regrow.

World generation

 * Dripstone Caves


 * A new underground 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 only be generated using buffet worlds with "Dripstone Caves" selected as the source biome or using custom world. Natural generation is planned for future versions.

Gameplay

Blocks

 * Banners
 * The unused "base" pattern has been renamed to the "field" pattern and given proper translation strings (its ID is still "base").


 * Cauldrons
 * Can now be filled with lava and powder snow.
 * Lava filled cauldrons can damage players and mobs inside of them, and give off a redstone comparator signal of strength 1.
 * Powder snow cauldrons are formed when cauldrons are under the sky during snowfall.
 * Can also be filled with powder snow by a powder snow bucket on it.
 * Have been split into normal, water, lava, and powdered snow cauldrons.

 * "Data" can be accessed by clicking the mode button while holding the key.

Mobs

 * Shulkers
 * If a shulker is hit by another shulker's projectile, it now has a chance of spawning a new shulker. Shulkers are more likely to spawn new shulkers when there are fewer shulkers nearby.

World generation

 * 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.

General

 * Height limit
 * May be increased. It is considered to change only in the overworld as stated by Jeb.
 * World-height related values are now exposed for customized worlds, which might confirm that height limit might get removed or increased.

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.
