Client Metadata format

The client_metadata.json file is used to track what patchline the world was last loaded with. If the patchline is different from what the world was last loaded with the game will display a message warning you that loading the world on a different patchline could break things, with an option to create a backup before entering the world.

JSON format

  • : Root object.
    • CreatedWithPatchline: The patchline the world was last loaded with. Either "release" or "pre-release".
