Minecraft Snapshot 21w05b

Today's photo shows us adding a few blocks that you will later see in the lush caves. They aren't quite as lush as Jens' hair but they're close enough.

Update: We have now released 21w05b in order to fix a few bugs.

Fixed bugs in 21w05b

MC-203813 – Copper blocks are not named consistently
MC-213788 – The game can randomly freeze
MC-213802 Copper is not properly upgraded from pre-21w05a worlds

21w05a: New Features

- Azalea bushes and flowering azaela bush!
- Added glow berries and cave vines!
- Added drip leaves
Hanging roots and rooted dirt were added as decorative blocks to the upcoming lush caves!
- Added moss
- Added spore flower!

Cave vines and glowberries

Cave vines are like weeping vines that grow from the ceiling.
- They have the potential to produce glow berries when they grow.
Glow berries can be used as a natural light source and a food source.
- Foxes eat glowberries
To plant new cave vines, use glow berries
- Bonemealing a cavevine will produce glow berries


- Small dripleafs need moisture to grow so they can be grown on clay or underwater
When bonemealed, small dripleafs become big dripleafs
- When bonemealed, the big dripleaf grows taller
- If you are standing on a large dripleaf, it will tilt and eventually fall off.
To prevent a big dripleaf of water from tilting, you can crouch or jump.
After a while, a big drip leaf that is tilted will start to tilt again.
- A projectile can cause the big dripleaf to burst.
- Sometimes, the wandering trader will sell small dripleaf plantlets

- Two new decorative blocks are now available: moss block, and moss carpet
- Moss blocks can be used to make moss carpet

Spore blossom

- A large, beautiful flower that is placed on ceilings
- It lets particles drip from it

Changes in 21w05a

- You can use the stonecutter to make different types of copper blocks
- Copper oxidization is now known as "Copper Block", Exposed Copper Block, "Weathered Copper Block" or "Oxidized Copper Block". They are arranged in a sequence from least to most oxidized.
Drowned can now drop a copper ingot but they cannot drop gold ingots
- New sculk sensor events added
- Powder snow changes

Sculk Sensors Changes

The following game events were added to the Sculk Sensor's response, along with the frequency value.

Block Change refers to when a player or dispenser has changed a block. Example: A cake slice being eaten
Mob Interact is a place for mob interactions that cause vibrations
Prime Fuse can be used for both TNT or Creepers

Powder snow changes

Flaming Arrows are now extinguished when they collide in powder snow
- Skeletons can now be frozen as strays and become skeletons
- Powder snow can now be pushed by pistons and sticky pistons
Foxes can now walk on powder snow without fear of falling

Technical Changes in 21w05a

- Increased performance when you use many overrides on an article model
- Copper oxidization now occurs randomly and is affected by the randomTickSpeed rule
