HuskSync 3.6.1 is a bug-fixing update that also makes some improvements to plugin commands.

• Commands are now natively registered via Brigadier where possible, and will provide rich syntax suggestions on Paper/Fabric servers
  • The brigadier_tab_completions option has been removed.
• Added an option to disable individual HuskSync commands and prevent them from registering (disabled_commands)
• The username argument is now required for the list and view subcommands of /userdata
• Fixed compatibility with Minecraft 1.21 on Paper servers
• Fixed various inconsistencies preventing the MongoDB database mode from fully working, courtesy of @Stampede2011 (#321)
• Fixed locked maps in Shulker Boxes not having their map data persisted on data save (#322)
• Fixed the section header comment being incorrect for the sync settings section of the config file
• Fixed various issues with the Fabric version of HuskSync, including issues syncing the first hotbar slot

To update, just drag+drop. You may wish to regenerate your config.yml file for the updated command options.
