🌍New Features in 20w49a

Dripstone Caves biome
- Contains plenty of pointed dripstone on the floors, ceilings, and small pools of water.

Wool Occlusion

⚙️ Technical Tidbits
- Sculk sensors have a cooldown period of 1 tick after being placed or after deactivating.
- During this short cooldown period, it cannot detect vibrations. This is to prevent it from activating itself when a contraption it is powering is being unpowered. Feedback is welcome on this point!

🔃 Changes in 20w51a

Sculk Sensors
- Eating Start has been removed as an event for a few reasons.
- It is inconsistent with our philosophy around vibrations. Mining a block is not considered a vibration because a physical event hasn't happened in the world yet (you can stop mining and the block will revert). This is the same for eating: you can start eating, but then stop and the food reverts as if eating never occurred.
- It wasn't widely considered to be a useful event for players to use sculk sensors with.
- Eating Finish is staying, and will likely be much more useful to sculk sensors for this scenario.
- Walking on wool no longer causes vibrations.
- Throwing wool as an item onto the ground no longer causes vibrations.
- Sculk sensors are now silent while waterlogged.

⚙️ Technical Changes in 20w51a

🌍 Happy Friday! We're now releasing 1.16.5, which fixes two critical stability issues. We are not releasing more information about these issues at this time to protect servers that have not yet updated.

This release is network compatible with 1.16.4 - this means you do not need to upgrade your game right away to play on an upgraded server. However, we highly encourage all server owners to update as soon as possible to apply the stability fixes.

Next week, we aim to release the next snapshot of Caves & Cliffs. Stay tuned!

👥 Noise caves and Aquifers
- Noise caves are a new way of generating caves, providing more natural variety. They can get really huge sometimes! Noise caves come in two flavors: Cheese caves. Like the holes in swiss cheese. These often form caverns of various sizes. Spaghetti caves. Long squiggly tunnels, sometimes wide like tagliatelle.
- Cheese caves. Like the holes in swiss cheese. These often form caverns of various sizes.
- Spaghetti caves. Long squiggly tunnels, sometimes wide like tagliatelle.
- No, they aren't loud. The "noise" part of noise caves is a technical term and has nothing to do with sound.
- The old cave carvers and canyons still generate, combining with the noise caves to form interesting cave systems.
- As with carvers, when noise caves intersect the surface they form cave entrances.
- An aquifer is an area with local water level, independent of sea level. Aquifers are used during world generation to generate bodies of water inside noise caves. This sometimes results in large underground lakes!
- For now, aquifers are only used below y31. This means all noise caves between y31 and sea level (y63) will be flooded with water, and noise cave entrances will essentially be lakes. This will be fixed later.
- Magma sometimes generates at the bottom of underground bodies of water.
- Underwater cave carvers and underwater canyons have been removed since aquifers are used to generate water in caves instead.
