Minecraft - Caves & Cliffs: Part I - 1.17.0 (Bedrock)

Delve into Part I of the Caves & Cliffs update with fun mobs, blocks, and items! Go underwater to team up with the Axolotl and swim alongside the Glow Squid. When you reach higher ground, tread carefully because the Goats might ram you! Want to build a settlement that changes over time? Mine Copper and use it to build structures that will age right before your eyes. Have some spare Copper? Craft a Lightning Rod or go mining in an Amethyst Geode and make a Spyglass! If you want even more blocks, the Wandering Trader might have a lush surprise for you. This is a BIG changelog, so let’s jump in!

Please search for any bugs you find on bugs.mojang.com and let us know what you think at feedback.minecraft.net.

New Features:

Axolotl

Axolotls are amphibious creatures that spawn in underground water
Holding a Bucket of Tropical Fish will cause nearby Axolotls to follow the player on both land and in water. Axolotls cannot be tamed but can be bred by feeding them Buckets of Tropical Fish
Axolotl will attack Fish, Squid, Drowned, and Guardians!
Axolotls come in a variety of colors, all with an equal chance of spawning except for blue. Blue Axolotls have a small chance of spawning as a mutation when breeding two Axolotls
Axolotls can survive on dry land for a few minutes. After that they will start to dry out and take continuous damage until rehydrated
When taking damage, there is a chance that the Axolotl will play dead. While playing dead, the Axolotl will regenerate health and mobs will be unable to target the Axolotl
When a player kills a mob that the Axolotl was attacking, they are rewarded with the regeneration effect and their mining fatigue is removed, if they had it
Axolotls can be picked up with buckets, just like fish!

Goat

The winning mob of the MINECON Live 2019 mob vote!
For now, Goats spawn in Extreme Hills. This will change with Caves & Cliffs: Part II
Goats will occasionally ram into players and other mobs
Goats can jump high and take less fall damage than other mobs
Goats will avoid walking onto Powder Snow
Goats can be bred and tempted using Wheat
Use an empty Bucket to get Milk
Keep an ear out for the elusive Screamer Goat!

Glow Squid

The winning mob of the Minecraft Live 2020 mob vote!
Glow squids are aquatic creatures that spawn in underground water
When killed, glow squid drop Glow Ink Sacs

Glow Ink Sac and Glow Item Frame

Craft a Glow Item Frame by combining a glow ink sac with an item frame in a crafting table
Any item in a Glow Item Frame is perfectly illuminated, even at night!

Glow Ink Sac and Glowing Sign Text

If a Sign is interacted with a Glow Ink Sac, the text will then get a glowing effect

Powder Snow

Mobs inside a block of powder snow start to freeze and eventually take damage
Players can protect themselves from powder snow by equipping leather armor
Cauldrons fill up in snowy weather, creating a renewable source of powder snow. It will also generate naturally in certain snowy biomes when Caves & Cliffs: Part II releases
Buckets can be used to scoop up and place powder snow
Most mobs cannot walk on powder snow and fall into the block instead
Skeletons transform into strays after standing in powder snow for awhile
Wearing Leather Boots allows a player or mob to walk on Powder Snow without falling in

Glow Lichen

A dim light source that appears on cave walls and in underground lakes
Use bone meal to spread it along block surfaces and harvest it using shears

Amethyst Geodes

These huge Geodes can be found anywhere underground of newly generated chunks in the Overworld
Amethyst Geodes have an outer layer of Smooth Basalt Blocks and a second layer of Calcite Blocks
Inside Geodes, there is an inner layer of various Amethyst Blocks
All types of Amethyst blocks (including Clusters) create beautiful sounds when you walk on them, break them, place them, or hit them with a projectile – go make some music!
Amethyst comes in block form inside the Geodes in two ways: Block of Amethyst Block and Budding Amethyst

Amethyst Clusters

Amethyst Clusters grow from budding Amethyst, which can be found inside Geodes
Clusters have four growth stages: Small Amethyst Bud, Medium Amethyst Bud, Large Amethyst Bud, and Amethyst Cluster
Fully-grown Amethyst clusters drop four Amethyst Shards (or more with the Fortune enchantment) when a Pickaxe is used, and drop two Amethyst Shards when broken by hand, Piston, or other means
Clusters can be mined with the Silk Touch enchantment at any stage of growth

Budding Amethyst

On any side of a Budding Amethyst Block where there is air or a water source block, a Small Amethyst Bud will eventually grow
Amethyst Buds can only grow when attached to Budding Amethyst, and will grow until they become a full Amethyst Cluster

Cluster Amethyst Blocks

Clusters can only grow when they are placed on budding Amethyst Blocks

Amethyst Shards

Amethyst Shards are items used in a variety of crafting recipes

Tinted Glass

Though visually transparent, light does not pass through Tinted Glass
Can be crafted by putting a Glass Block in the middle of four Amethyst Shards on a Crafting Table
Tinted Glass can be obtained without the Silk Touch enchantment and does not shatter when broken, like normal Glass

Copper

Copper Ore can now be found underground in newly generated chunks and can be smelted into Copper Ingots
Block of Copper and Cut Copper can be crafted, as well as stairs and slabs
After being placed in the world, Copper Blocks will oxidize slowly over time, turning to exposed Copper, Weathered Copper, and Oxidized Copper
Copper Blocks that are not fully oxidized can be waxed to prevent further oxidation, either by using a Honeycomb item on them, by using the crafting grid, or by using a Dispenser loaded with Honeycombs
Axes can scrape off wax and oxidation from Copper Blocks

Lightning Rod

All lightning strikes that happen within a radius of 64 blocks from a Lightning Rod will strike the Lightning Rod
Lightning rods can be crafted using Copper ingots in a Crafting Table
A Lightning Rod struck by lightning will emit a full Redstone signal for 8 game ticks

Spyglass

The Spyglass is used to see far away places and can be crafted with Copper Ingots and an Amethyst Shard
Camera movement when looking through a Spyglass is slowed to make it more comfortable to use. This is adjustable using the Spyglass Damping slider in Settings on Bedrock Edition

Raw Ore Items

Added Raw Copper, Raw Iron, and Raw Gold items
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 are still smeltable, meaning you can still smelt ore blocks you've obtained previously or with the Silk Touch enchantment

Raw Ore Blocks

Added block of Raw Copper, Raw Iron, and Raw Gold
Just like other ore materials, you can craft a compact block with raw ore items to save inventory space or use as decoration
Raw ore blocks can be placed on a crafting grid to break down into the original raw ore items

Deepslate

Deepslate is generated in blobs below y = 16
Mining it with a Pickaxe will drop Cobbled Deepslate, which can be smelted back into Deepslate
When ore is generated in the same place as Deepslate, Deepslate variants of that ore are now generated instead
Deepslate Blocks can be crafted into Polished Deepslate, Deepslate Tile, and Deepslate Brick Blocks, including slabs, stairs, and walls
Deepslate Blocks also come in Cracked Tile, Cracked Brick, Chiseled, and Infested variants
Stone tools can be crafted using Cobbled Deepslate

Tuff

A new decorative block
Blobs of Tuff Blocks generate in the world below y = 16

Smooth Basalt

Basalt blocks can now be smelted into smooth basalt blocks as a new decorative block

New Cave Blocks

While Lush Caves and other new cave biomes won’t generate until the Caves & Cliffs: Part II update, many new blocks are now available through the Creative mode inventory or certain aspects of Survival mode

Trade & Loot Table Additions

Added the following trades to the Mason:
- Will sell 4 Dripstone Blocks for 1 Emerald
Added the following trades to the Wandering Trader:

- Will sell 2 Rooted Dirt for 1 Emerald
- Will sell 2 Moss Blocks for 1 Emerald
Moss Blocks can be found in Shipwreck Chests
Glow Berries can be found in Mineshaft Chest Minecarts

Dripstone Block and Pointed Dripstone

Pointed Dripstone can be placed on the ceiling (stalactites) or ground (stalagmites)
Watch out! If a stalactite is broken, it will fall and cause damage to players and mobs
Players and mobs will take damage if landing on a stalagmite
If a stalactite is under a water source or lava source, it will slowly fill Cauldrons
If a stalactite and stalagmite touch, they will connect into a full column
A Dripstone Block can be crafted with four Pointed Dripstone

Dripleaf

Small Dripleaf will grow into Big Dripleaf when fertilized with Bone Meal
Big Dripleaf is a platforming block. Players and mobs on top of the block will cause the block to tilt and drop

Moss Block and Moss Carpet

When Moss Blocks are fertilized with Bone Meal, Moss has a chance of spreading to other blocks. Moss Carpet, Azaleas, and Flowering Azaleas also have a chance of growing
The Hoe is the most efficient tool to harvest Moss Blocks and Moss Carpet

Azalea

Azalea and Flowering Azaleas are new decorative plants
Azaleas have a chance of growing after using Bone Meal on Moss Blocks
Fertilizing an Azalea with Bone Meal will transform it into a tree with Azalea Leaves and Flowered Azalea Leaves, which can be harvested using Shears
Azalea and Flowering Azalea can also be used as Furnace fuel

Rooted Dirt and Hanging Roots

Tilling Rooted Dirt with a Hoe turns the block to normal Dirt and drops Hanging Roots
Fertilizing Rooted Dirt with Bone Meal causes Hanging Roots to grow below

Glow Berries

Glow Berries can be planted on the bottom of most solid blocks to grow cave vines
They can be eaten and are as nutritious as Sweet Berries
Use them to lure and breed Foxes

Cave Vines

When Cave Vines grow or are fertilized with Bone Meal, they have a chance of growing Glow Berries
A Cave Vine that has Glow Berries emits light. So pretty!
Cave Vines are climbable

Spore Blossom

Technical Updates:

Updated Add-On Template Packs

Updated Add-On templates for 1.17 are available for download with new resources, behaviors, and documentation
- Resource Pack Template: aka.ms/ResourcePackTemplate
- Behavior Pack Template (Includes documentation): aka.ms/BehaviorPackTemplate

General

Added two new variables to the 'biomes_client.json' file: "remove_all_prior_fog" and "inherit_from_prior_fog", which control fog merging and/or inheritance
"remove_all_prior_fog", when true, will clear all previous fog definitions stored on the stack, making the current pack the new "starting point" for fogs
"inherit_from_prior_fog", when true, will merge a biome's fog definition with matching biomes on the stack then create a new merged definition for it
"transparentattachable" tag should only affect rendering in first person camera perspective
Added a MoLang query to get default bone pivots (MCPE-116741)
Updated MoLang query to return normalized item use time remaining based off given parameters (MCPE-116737)
Fixed various cases when ray tracing textures would not be reloaded (resolution switching, upscaling mode switching, ray tracing on/off toggling) (MCPE-124562)
Fixed Enchanted Bow's textures being too dark (MCPE-119701)

Actors

Catmull-Rom animations will no longer glitch if the time for a keyframe matches its value
All functions run using the '/schedule' command now run from the origin they are supposed to, instead of from the server
Added a new field "transform_to_item" to the "minecraft:ageable" component. If the field is filled with an item name, the item will be given back when any of "feed_items" are used. Similar to "transform_to_item" in the "minecraft:breedable" component
Added a new optional flag "use_simplified_breeding" to "minecraft:genetics" component. When this flag is set to true, the offspring never inherits hidden alleles of parents as main alleles and main as hidden. This allows to implement simple breeding logic easier

Other Fixes

Fixed a crash that could occur when an entity with a scoreboard value was removed from the world
Fixed a bug with the summonable property of overridden Vanilla mobs pre-JSON version 1.8.0, which caused Bees to not be summonable (MCPE-58557)
