Caves & Cliffs



Caves & Cliffs is the name of two major themed updates for. The first part was released as Java Edition 1.17 and Bedrock Edition 1.17.0 on June 8, 2021, which focused on blocks and mobs. The second part was released as Java Edition 1.18 and Bedrock Edition 1.18.0 on November 30, 2021, and brought revamped overworld generation, including new caves and mountains.

Caves & Cliffs was announced in Minecraft Live 2020, and on April 14, 2021, Mojang Studios announced that the update would be split into two portions due to the amount and complexity of content, as well as team health. It was later announced in Minecraft Live 2021 that the Deep Dark portion, as well as certain items, of the Caves & Cliffs update would be delayed until The Wild Update to improve quality.

On, Part I started development with snapshot 20w45a, which was released on November 4, 2020. The first pre-release for Caves & Cliffs: Part I was released on May 27, 2021, and the first release candidate on June 4, 2021. Part II started development with 1.18 Experimental Snapshot 1, which was released on July 13, 2021, followed by the first pre-release on November 11, 2021, and the first release candidate on November 25, 2021.

On, Part I started development with beta 1.16.200.52, which was released on October 28, 2020. Most of the Part I features were behind experimental gameplay toggle until the Part I release and were not included in the full 1.16.200, 1.16.210, and 1.16.220 release. In Part II, development continued with beta 1.17.30.23, which was released on August 25, 2021. In 1.17.10, released on July 13, 2021, non-beta users were able to test out most of early Part II features behind experimental gameplay.

 * Come in two forms, stalactites and stalagmites.
 * Stalactites hang from the ceiling and drip water or lava, based on what is above them. The stalactites drip water naturally without a source block above it, but these drips do not fill a cauldron.
 * Placing a cauldron under a stalactite slowly fills the cauldron with water or lava depending on the source block above them (enables renewable lava).
 * If the block on which a stalactite hangs is broken, the stalactite falls, causing damage to players and mobs directly underneath. They do not take any damage if they are airborne.
 * Stalagmites are found on the floor of the cave and deal damage if landed on.
 * The damage inflicted of pointed dripstone is directly proportional to the height from which the stalactite or player/mob falls from.


 * Powder Snow.png Powder snow
 * Similar to snow, but entities fall through it. The fall is similar to the effect of cobwebs, but faster.
 * If the player does not have any leather armor equipped and they walk or fall in, they start to freeze and take damage.
 * Freezing lowers the player's FOV (field of view), turns the health bar blue, and puts a frosty vignette on their screen.
 * Any leather armor prevents freezing.
 * Wearing leather boots allows the player to walk on top of powder snow and make it function like scaffolding.

 * Comes in four common varieties, lucy (pink), wild (brown), gold, and cyan, and a rare blue variety, which has a $1/1200$ (~0.08334%) chance of spawning. This fraction is based on the fact that there are about 1200 axolotls left in the wild.
 * Has a 1/3 chance to play dead when damaged, receiving Regeneration I for 10 seconds, recovering.
 * This regeneration ability is likely based on how real axolotls can regrow lost limbs.

Vibrations are not caused by ambient weather such as rain or snow.

General

 * Terrain
 * Terrain generation is now independent from biomes, with biomes adapting to whatever terrain they happen to generate throughout.
 * This allows for natural variation in the terrain of any individual biome, both in terms of shape and elevation.
 * For example, forests and deserts could form up on a hill without needing a special biome just for that purpose.
 * This additionally allows for smoother transitions between biomes.
 * Terrain is now smoother and more extreme.


 * Height limit
 * Has been increased to 384 blocks, expanding 64 blocks up and 64 blocks down, with 320 being the limit upward and -64 being the limit downward.


 * Ores
 * Most of the overworld ores have been retextured and touched up mainly for accessibility reasons. These also apply to the new deepslate ores.
 * This is a great help for color blind people that have difficulties distinguishing a certain ore of similar texture from another.
 * Diamond ore is an exception to this for being the "iconic" ore of the game, making Minecraft developers want to keep the classic feel of it.
 * Ore distribution has been changed for more strategic mining.
 * Certain ores are more common at certain depths, and some may generate in lower quantities or not generate at that level at all.


 * Upgrading old worlds
 * The biomes and terrain from old and new chunks now seamlessly blend, preventing the hard cut borders from before. Any player-made structures in these chunks may either be intact, buried, or deteriorated.
 * The old bedrock layer between Y=0 and Y=4 in old chunks gets replaced with deepslate.
 * A new bedrock layer is placed between Y=-64 and Y=-60.

Trivia

 * Mojang Studios employees explored real caves to research for the update. This helped give inspiration and ideas for the update, including for the noodle caves (previously called mesh caves).
 * Henrik Kniberg also recalled memories of past visits to caves around the world.
 * The art style of the concept art for Caves & Cliffs was inspired by the concept art of the Adventure Time episode Diamonds and Lemons, which was a crossover with Minecraft.
 * Archaeology and Bundles were originally planned to be added in this update, but were delayed to a later version when the update was split.
 * The deep dark biome, sculk family blocks, the warden, and goat horns were also originally planned for this update, but have now been postponed to release alongside The Wild Update.


 * Trailer Trivia
 * At the 0:24 mark of the Caves & Cliffs: Part I trailer, the constellation can be spotted in the sky, which represents the sea-goat and is the Latin name for goat horn.
 * In the same trailer at 0:30, a Necromancer laugh from Minecraft Dungeons can be heard.
