Caves & Cliffs is the name for an upcoming major update that will be released in mid-2021 for most versions of Minecraft, likely as Java Edition 1.17 and Bedrock Edition 1.17.0. It was announced in Minecraft Live 2020.[1] It will include new cave and mountains features, as well as the glow squid, a mob that was voted for during the second Minecraft mob vote.

Gameplay
- Archaeology
- The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.

- Diamond blocks
- Emerald blocks
- Ceramic shards of varying color which depict different images.
- Dark flashing [Note 1]
- While in the Deep Dark biome, the screen occasionally darkens limiting the player's visibility. This serves a warning that the warden is nearby.[4]

Planned changes
World generation
- Revamped to generate bigger, more adventurous caves.

- Local water levels
- A new generation aspect has been introduced, which allows for certain areas of a world to generate with a water level different than another area.
- Allows for the generation of larger underground lakes and connections to oceans.
- Allows for the generation of many underground waterfalls.
- Allows for underwater entrances.
- Mountains
The preview of updated mountain generation given during Minecraft Live 2020.
- Revamped, featuring some new small spruce trees on the slopes and ice or packed ice above the peaks.
- Contain powdered snow and goats.
- Will be revamped, at least for copper.
- based on what was said during Minecraft Live 2020, it could work like where when a group of ores are mined, some stone might look slightly different, and when that stone is mined, more of the ore will be found behind it
Trivia
- This is the first update to add a new ore to the overworld since Java Edition 12w21a in 2012 for Java Edition 1.3.1 when emerald was added, and the first to add a real-world metal into the game since Java Edition Classic 0.0.14a in 2009, which brought both iron and gold.
- Although the axolotl will be the first amphibian mob implemented into Minecraft, it was not the first announced since frogs were announced during the 2019 biome vote and cited during the development of Pocket Edition 0.14.0 by Jason Major.
- Despite ores being shown to emit light during the reveal of this update, this was later confirmed to be just for demonstration purposes, and not for the final version.
