This latest Minecraft snapshot brings us some experimental features that we’re pretty excited about! Added support for custom world settings and dimensions could make for some pretty incredible worlds and we’re ecstatic to dive in and take a look!
New Features in 20w21a
Added the ability to toggle redstone wire between a cross and a dot
Added import/export world settings functionality
Added a new disableMultiplayer command line option – when used, the Multiplayer button is disabled
Added a new disableChat command line option – when used, receiving and sending online chat is disabled
When right clicking a single piece of redstone, it toggles between a the cross and the dot
A dot of redstone will not power its surrounding blocks
Changes In 20w21a
Piglins no longer walk around when admiring gold
If you hurt a piglin while it is admiring an ingot, the ingot will now disappear
Increased the chance of ores to generate in the Basalt Deltas to balance against the reduced amount of Netherrack in this biome
Lily pads are now considered junk fishing loot rather than treasure
Updated logos for Mojang Studios and Minecraft
Temporarily removed structure settings from flat level preset strings (workaround: use import/export settings functionality)
Technical Changes In 20w21a
Added the ability to control the height of the spreadplayers command
Added custom worlds and custom dimensions
Added an optional argument to specify maximum height.
New syntax: spreadplayers <center> <spreadDistance> <maxRange> [under <maxHeight>] <respectTeams> <targets>
maxHeight – Specifies the maximum height for resulting positions
Structure names are now specified as lowercase
Added experimental support for new custom worlds
Edit world screen now has an option to export world settings to a JSON file
During world creation you can import previously exported world settings
A bunch of new parameters are exposed, but marked as experimental, meaning you can play with them, but there is no guarantee that any of them will continue working (even in the next snapshot!)
Flat level preset string lost structure settings (they are now stored in a common format for all worlds), we will restore some form of this functionality soon
Buffet world can no longer be created from server.properties, flat level settings changed a bit; better support for custom world creation on the server is coming soon
The update is closer than ever before!
Mojang has still yet to reveal the release date for the new Nether Update but we hope you enjoy catching up on all of the latest changes that are in store! We hope to see incredible builds and creative uses of all of these new changes as well!
