Amethysts

Amethyst Blocks

Amethyst comes in block form inside the geodes in two ways: Block of Amethyst and Budding Amethyst
All types of Amethyst blocks (clusters included) create beautiful sounds when you walk on them, break them, place them, or hit them with a projectile - go make some music!

Amethyst Clusters

Amethyst Clusters grow from Budding Amethyst, which can be found inside geodes
Clusters have 4 growth stages: Small Amethyst Bud, Medium Amethyst Bud, Large Amethyst Bud, and Amethyst Cluster
Clusters can only grow when they are placed on Budding Amethyst blocks
Fully-grown Amethyst Clusters drop 4 Amethyst Shards (or more with Fortune) when an Iron Pickaxe or higher is used, and drop nothing otherwise when broken
Clusters can be Silk Touched at any stage

Amethyst Geodes

These huge geodes can be found anywhere underground in the overworld
Amethyst geodes have an outer layer of a new stone called Tuff
Amethyst geodes have a second layer of another new block called Calcite
Amethyst geodes have an inner layer of various Amethyst blocks

Amethyst Shards

Amethyst Clusters drop 4 Amethyst Shards (or more with Fortune)

Budding Amethys

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 Amethyst Clusters

Bundles

Bundles are items that hold other items.
A bundle can hold a mixture of items, but only one stack's worth. For example, a bundle could fit:
- 64 dirt
- 32 dirt + 32 stone
- 32 dirt + 8 ender pearls
- 1 of every color of wool, concrete, carpet and terracotta (64 blocks in total)
- Or 1 diamond helmet
Use right click to put an item into a bundle.
Right-click a bundle to empty it.
Wrap a present in a bundle and give it to your friend!

Candles

Candles come in all 16 colors + 1 uncolored variant
Up to 4 can be placed in one block
Candles allow you to properly wish someone a happy birthday
Waterloggable! (But you cannot light them underwater, silly)
Wish anybody a happy birthday with a candle cake!

Cauldrons

Cauldrons can now be filled with buckets of lava!
Filled lava cauldrons give off a redstone signal of strength 1

Copper

Copper blocks

Craft 9 copper ingots to a copper block
Craft cut copper, cut copper stairs and cut copper slabs
Use honeycomb to craft waxed copper blocks

Copper ore

Copper ore can be found in ore blobs across Overworld, similar to iron and coal (this is not the final generation for copper…)
Smelt copper ore to get a copper ingot

Lightning Rod

The Lightning Rod is crafted from three copper ingots
Keep your builds safe (well, as long as the closest area around the lightning rod is fire proof) during thunderstorms!
The lightning rod will protect an area of 4 * 16 blocks around it from the, sometimes devastating, lightning strikes!
Lightning rods give off a redstone signal when struck by lightning

Oxidation

Copper will oxidize over time
There are for stages: copper, lightly weathered copper, semi-weathered copper and weathered copper
It takes 50 - 82 Minecraft days (in loaded chunks) for a copper block to oxidize one stage
Waxed copper blocks will not oxidize
You can wax any oxidation stage - how lovely that means you can keep that pretty lightly weathered copper block in it's lightly weathered stage forever!

Spyglass

You can use your spyglass to see faraway things
Pretend to be a sea captain, or catch your neighbor in the act as they dye your sheep lime green
The spyglass is crafted from two copper ingots and one amethyst shard

Tinted Glass

Tinted Glass is a type of glass that does not allow light to pass through
Tinted Glass is crafted by putting a Glass block in the middle of 4 Amethyst Shards
Tinted Glass can be obtained without silk touch; it does not shatter like normal glass

Changes in 20w45a

Experience orbs now sometimes merge when in large quantities to improve performance. This does not change the rate at which the player can absorb them, it simply limits the amount of separate orbs floating around in the world. Orbs that merge will gain the lifetime of the most recently created one.
Simple firework rockets with 1 gunpowder can now be crafted using the recipe book
Dirt paths (formerly grass path) can now be made by using a shovel on dirt, podzol, mycelium or course dirt (as well as grass)
Minecarts and rails work in water
Particles now appear when pistons break blocks

Minecarts

Minecarts and rails now work in water

All rails can be waterlogged (works with a dispenser & water bucket too)
Flowing water doesn't break rails
Minecarts can pass through water, but get slowed down more than usual

Technical Changes in 20w45a

Entities are now saved separately from terrain chunks.
Added loot table function set_banner_pattern
Pack format in version.json has been split into data and resource versions
Servers can now require custom resource packs to be accepted

Custom server resource packs

A dedicated server can enforce custom resource packs by setting require-resource-pack in server.properties. When this option is used, players will be prompted for a response and will be disconnected if they decline the required pack.

Entity storage

Entities have been extracted from main (terrain) chunks and are now stored in separate entities directory (similar to POI storage). Those new files are still region files with NBT.

Loot tables

New functions

`set_banner_pattern`

Sets tags needed for banner patterns. Parameters:

patterns - list of pattern objects:
- pattern - name of pattern (square_bottom_left, bricks, etc.)
- color - name of color (light_gray, etc.)
append - if true, new elements will be appended to existing ones instead of replacing
