For server owners on POSIX-compatible systems (Linux and others), you can set the `player-permissions` config value to set the file permissions that the player data should have on saving to the shared directory. Minecraft versions up to 1.20.1 set read permissions to the group; this is no longer the case. This lets you revert this behavior. Don't use unless you know what you're doing, you could break the sync process!
This release improves the reliability of setting spawn using beds. Custom behavior was eliminated, allowing standard vanilla gameplay. This also restores the proper functionality on respawn anchors.
This update fixes the long-standing issue of stray chunks getting generated in some cases; this mostly happened when coordinates were wildly different between worlds.
