Minecraft 1.16 Snapshot 20w21a is a medium sized snapshot with a brand new custom world / dimension creator. You can now add your own custom worlds and dimensions! This is awesome.

Features:

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.
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).

Redstone Toggle:

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.

Custom Worlds:

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.
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.
