This release adds a Friend Code Type selector, with options for Session Code (the default, same as previous versions of the mod) and World Code (which stays the same when you close and re-open the world).
These newly added World Codes are securely stored, so even if you do share the world files with someone, they will not be able to impersonate the World Code.
This release also supports proper passwords for the SAM bridge. These will be automatically enabled.
