Caves & Cliffs is the name of two major themed updates for Java and Bedrock editions. 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 Java Edition, 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 Bedrock Edition, 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.

Both Java and Bedrock editions received Caves & Cliffs: Part I on June 8, 2021, and Caves & Cliffs: Part II on November 30, 2021.

Additionally, features from Caves & Cliffs: Part I, were released for Minecraft Education in 1.17.30 on November 2, 2021. Part II features were released in 1.18.32 on August 9, 2022.

For China Edition, Caves & Cliffs: Part I was released on January 21, 2022, and Part II on August 26, 2022.

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 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 Capricornus 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.

Unconfirmed features

These features are not confirmed for 1.17, but were mentioned or showcased by developers during the development of 1.17. Main article: Mentioned features.

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.
• As of 20w49a. 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 Java Edition update to add a new ore to the overworld since emerald ore was added in 1.3.1 (12w21a) in 2012.
  • Similarly, this is also the first Java Edition update to add a real-world metal into the game since Classic 0.0.14a in 2009, which brought both iron and gold.
