 ### Notes
 
-- Email is currently not supported by Twitter OAuth 2.0.
-- You must enable the "Request email address from users" option in your app permissions if you want to obtain the users email address.
+- Auth.js now uses Twitter/X OAuth 2.0 by default. There's no need to set `version` anymore.
