1.17, the first release of Caves & Cliffs, is a major update to announced at Minecraft Live 2020 and released on June 8, 2021. This update adds amethyst geodes along with amethyst blocks and items, copper ore and its derived forms, deepslate and its variants, and the goat, glow squid and axolotl mobs.

On April 14, 2021, Mojang Studios announced that the update would be split into two updates due to the amount and complexity of content, as well as team health. Multiple features such as revamped mountain and cave generation, the lush caves and dripstone caves biomes, and increased world height were removed on 21w15a, and are set to release for 1.18. A data pack was included in the Minecraft.net article for 21w15a that re-enabled the removed features, and subsequent snapshots updated this data pack. The latest data pack for the full 1.17 release, named the Caves & Cliffs: Part II Preview, can be downloaded here.

 * 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 causes it to tilt.

 * Small dripleaf can be obtained only with shears (otherwise breaks) and can be planted on clay or moss blocks, or underwater on clay and dirt blocks.
 * Big dripleaf can be obtained with any tool or by hand and can be planted on grass, dirt, and moss blocks.

 * Up to 6 can be put on the same block space, merging into one block.

 * Obtained with shears, otherwise breaks.
 * It can be obtained using a hoe on rooted dirt turning it into normal dirt.


 * Infested Deepslate
 * An infested variant of deepslate.
 * Spawns a silverfish when mined.

 * Lightning Rod
 * Can be crafted with 3 copper ingots.
 * Lightning strikes within a 32-block radius get redirected to the lightning rod.
 * Turns completely white when struck by lightning.
 * Gives off a redstone signal with a strength of 15 if hit by lightning.

 * An opaque block with a grass-like texture on all sides.
 * Can be fertilized with bone meal to grow grass, tall grass, moss carpets, and both types of azaleas on it and in its vicinity.
 * Can be fertilized with bone meal to grow over (expand) across stone surfaces, but not grass surfaces.
 * Breaks when pushed by a piston or sticky piston.
 * Can be combined with cobblestone or stone bricks to make the mossy versions of those blocks.

 * Moss Carpet
 * Same texture as the moss block, but one pixel thick.
 * Can be crafted with moss blocks, or be obtained by applying bone meal to them.


 * 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. They also break 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 (as does lava in the Nether) but this effect alone 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. They also prevent fall damage when landing on powder snow.
 * Leather Horse Armor also protects horses from freeze damage.
 * When inside a powder snow block, a frosty vignette appears around the player's screen and any entity (with the exception of strays, polar bears, and snow golems) inside starts freezing and taking damage after a short time.

 * Right-clicking a bundle in the inventory empties one item from the bundle.
 * The player receives a tutorial when first having a bundle in the inventory.
 * 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.
