Minecraft: Java Edition - Snapshot 21w44a

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. 

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

Enjoy!

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
  • When JFR profiling is started from an external source, the JFR events for network packets are now aggregated instead of one event per packet
