21W14A Snapshot Update

The Minecraft Caves and Cliffs Update was set to be the game's biggest patch yet, but a new announcement has revealed it will be split into two updates coming this year!

Here's what you need to know about Minecraft Caves and Cliffs, and its release dates as two separate Minecraft updates.

LATEST - Caves and Cliffs Update Split Into Two, Release Dates Revealed

Minecraft 1.17 may not encompass Caves and Cliffs anymore, as the massive update will now be split into two updates instead!

As revealed in an announcement from Mojang on Wednesday, April 14th, the first part of Minecraft Caves and Cliffs will go live in the Summer, while the second part will go live around the holiday season.

Caves and Cliffs Beta

The Minecraft 1.17 Caves and Cliffs Beta has given players the chance to test out features from the upcoming update, and along with Snapshots, helps players along with the long wait.

Those wondering how you get access, don't worry, we've got you covered.

FINALLY: Players have been waiting for an update to make mining more enjoyable

Caves & Cliffs Update

Minecraft Live finally gave us confirmation of just what is coming in the next update!

In line with the leak ahead of time, we are getting a Caves & Cliffs Update!

Update 1.17 release date

There is no exact release date currently set for Minecraft Caves and Cliffs - though we do have a release date window for each of its 2 parts. Minecraft Caves and Cliffs part 1 will arrive in the Summer, while part 2 will arrive around the holiday season.

Given how long it was between the announcement of the Nether Update and it's release, Minecraft players were ready to wait a while for the next big update to the game, and we finally have a release date window for when content arrives.

Caves & Cliffs Update content

Minecraft is about to get a whole lot more beautiful, with more diverse and creative content planned for both caves and mountains.

There will be new biomes including lush caves filled with life, and dripstone caves filled with stalactites and stalagmites.

Variation in caves is the name of the game. There will still be a classic feel, but there should be something for everyone with the Caves & Cliffs Update.

DRIPSTONE CAVE BIOME: The deep caves are truly stunning

There are plenty of new mobs coming too. The terrifying Warden is coming to the deepest, darkest caves.

Along with that monstrous mob come more friendly ones! Axolotls will be added to the water, while goats are coming to the Overworld on the new mountains!

A new form of mining will arrive with the Caves & Cliffs Update that sees players carefully excavate rare and fragile artefacts by brushing away debris rather than whacking things with a pickaxe.

New ores

Search for the new copper ore or gorgeous Amethyst crystal geodes that can be mined for new crafting materials. With the Caves & Cliffs Update, there are going to be a ton of new blocks and crafting recipes including sculk sensors to detect movement, telescopes, lightning rods, leaf platforms, and a whole lot more.

Lush Caves

A new biome! Lush Caves promise to be full of life, bringing some colour and interest to the caves, along with the danger of tunnelling!

GLOW BERRIES: These light sources should transform your mining

There is a new tree, Azalea, which indicates where a Lush Cave is while on the surface.

Spore blossoms are a new block, a roof-hanging flower that gives off particles, similar to those in the new Nether.

This is where you'll find the cute axolotls in water pools too.

Redstone additions

The new sculk block will sense movement and send out a Redstone signal. Kind of like a motion sensor.

This new feature will be amazing in the hands of expert Redstone engineers as it plays like wireless Redstone!


This new mob lurks in the deep dark of new caves. Adapted to the darkness, it can sense movement and has fine-tuned hearing, so be careful!

Growing from an unobtainable block, these crystals are not only very pretty, but they are useful too! Key in a new recipe, you'll have to find them and then build around them.

Minecraft crystals

From the crystals you get shards that can be used to craft a telescope!!

To build it you'll need copper! That's right a new ore is finally coming to Minecraft. Copper blocks will turn green with age too, just like real life. This adds a sense of time to your world.

Limited inventory has always been a problem for Minecraft, and as more blocks get added players have been struggling with carrying items.

The Bundle will fix that. You can put multiple types of things into one Bundle, and full stacks of items too. That means you can carry just one Bundle and hold 64 cobblestone, 64 iron ingots, and some flowers in just one inventory slot!

Archaeology system

You've come across broken Nether portals, but now there are old archaeology dig sites!

With a hut and brushes, you can move aside parts of blocks to find hidden artefacts from the past.

Mojang account migration to Microsoft

Mojang is bringing Java Edition Minecraft players under the same umbrella as everyone else by forcing account migration to Microsoft.

This will add a few extra security features, especially for parents, but is mandatory and those reluctant to change will have to if they want to keep playing Minecraft!

21W14A Snapshot Update

Another smaller update has been released for Minecraft ahead of the Caves and Cliffs expansion that's due later this year.

This drip-feed method of updating the game has proven popular with players as it helps to keep the game fresh in lieu of a full update.

TO THE HILLS - The update is more than just underground updates

Below, we have everything you need to know about the update.

New Features

  • Added Raw Copper, Raw Iron, and Raw Gold items
  • Tuff blobs can now be found between heights 0 and 16

Smeltable Ore Drops

  • Ores that are smeltable now drop raw item forms of the ore instead of the ore block and these can be smelted just like before
  • This is to prevent cluttering the inventory and have consistency with Fortune on all ores
  • Ore blocks from old worlds and silk-touched ore blocks will continue to be smeltable

General Changes From 21W14A

  • Fully oxidized Copper can now be waxed
