Another snapshot is now available. We've added new world generation below existing chunks, and blocks and fluids are now also part of the simulation distance setting. We also fixed a few bugs. Enjoy!

Keep in mind that we're still working on the world upgrades, so making a backup before upgrading is still a good idea.

This update can also be found on minecraft.net.

If you find any bugs, please report them on the official Minecraft Issue Tracker. You can also leave feedback on the Feedback site.

New Features in 21w44a

• New world generation is now inserted under existing chunks when upgrading a world to the new world height
• Added an Online options screen where you can now find the Realms Notifications option and Difficulty when on a server
• Added an "Allow Server Listings" option to opt out of having your name displayed in server listings

Changes in 21w44a

• Sleeping now only resets the weather cycle if it was raining
• Blocks and fluids are now also affected by simulation distance. It might be a good idea to test that the behavior of your redstone contraptions remained the same
• Optimized entity collisions

Technical Changes in 21w44a

• Servers can now set property hide-online-players to true in order to not send a player list on status requests

What else is new?

If you want to know what else is being added and changed in Part II of the Caves & Cliffs Update, check out the previous snapshot post.

Force load creates its own sim distance bubble.

There are issues with having different simulation distance values for entities and blocks.

Exactly. And simulation is mostly beneficial for servers anyway.

It was a fake.

The focus right now is performance and world gen architecture. Whether it feels like it or not as a player, these optimizations and maintainance of code quality are monumental tasks with how much has changed this update. Because of this, things like Calcite/Tuff/Dripstone won't be getting extra blocks this update. We can never promise anything, but as with all ideas, it goes into the ideas library and it might be something we can revisit in future updates.

We thought about this problem when designing the spawning changes - mobs can still spawn in partial daylight, it's block light that they can no longer spawn at any light level in. As a result, mobs should still spawn in Dark Oak Forests perfectly fine :)

Refer to my reply to OP, ShimmerFairy is correct and it's as-designed to keep functionality like spawning at night under moon light as well as in dark forests.

You don't really need to know Swedish in Sweden.

Yes, that's the intention. If you find it's not the case please send us bug reports.

This was actually a concious design decision to implement terracing in the terrain. It's not for every hill/mountain, but for some of them. It's also for better gameplay, as straight slopes are really annoying to traverse. If they are terraces, they have flat steps up that allow you to walk straight on the sides.

You also don't have to add them into all platforms though. I know the difference, as someone who did modding for 10 years in Minecraft versus now being a Mojang employee. It is very different, and the process requires more quality checking. Unfortunately the way it is!

In 2 years here I've met 2 or 3 people who could not speak English. Yeah, labels are mostly in Swedish, but you usually see what you take. I'm slowly learning Swedish, not because I need it, but because I feel that it is a good and respectful thing to know the native language of a country I plan to live in for the rest of my life. So far it's not even required to know the language to get the citizenship.
