No dates have been given for the release of development versions of this update so far, or the final release.

Blocks

 * Pointed Dripstone
 * Does not generate anywhere currently, is only available from the creative inventory.
 * Can be placed on the floor or ceiling, creating stalagmites or stalactites respectively.
 * Can be combined to form longer stalactites and stalagmites.
 * Stalagmites break if not attached to something below, and hurt entities which fall on top of them.
 * Enemies that fall on the stalagmites deal three times more fall damage
 * Stalactites fall if unsupported, and hurt entities they fall on.


 * Powder Snow
 * Similar to snow, but entities fall through it, similar to the effect of cobwebs, but faster.
 * This is how regular snow layer blocks worked in old versions of Minecraft, but it was changed because it created accidental booby traps when lava pools generated at just the right height to cut out the ground but not the snow.
 * "Snowier snow" was announced to be part of the Mountains biome in the biome vote at MINECON Live 2019, which is related to powder snow.
 * When wearing leather boots, it acts like scaffolding and also protects from freezing.
 * If the player does not have leather boots equipped and they walk or fall in, they will start to freeze and take damage.
 * Freezing lowers the player's FOV (field of view) and puts a frosty vignette on their screen.
 * Any leather armor prevents freezing.


 * Sculk Sensor
 * Generates in the deep dark cave biome.
 * Can be used for wireless redstone.
 * Senses vibrations created by things such as block placement, footsteps, and projectiles, including fishing rods.
 * Wool can occlude its ability to sense. This can be placed between or completely around the source of the input.
 * Cannot detect players sneaking.
 * Can be used with a piston to create a wireless redstone clock.
 * Emits particles ( animation here: Particle of the Vibration.gif ) when it senses a vibration nearby except when waterlogged.
 * Are not affected by ambient weather such as rain, nor other sculk sensors and/or the warden.

Copper Block and variants

 * Honeycombs can be used to make waxed copper, which does not progress beyond the patina stage it has at the time.

Lightning Rod
