A significant update was pushed back to github. Documentation has been updated here.
Updates, documentation, and demos will still be hosted here at pointlesscrap.net but source is now available at GitHub.

What started out as a simple plan to support the improved desktop authorization for Facebook Connect - Authorization and Authentication for Desktop Applications - has turned out to be a significant overhaul of just about everything.
The old login process looked something like this:
What's fixed:
- persistent sessions should now work correctly in 10.6
- debug builds should really log to the console this time
- fetchFacebookData: should no longer always return nil in 10.6
This is a minor update to fix a few compile warnings in 10.6.
Changes:
- grantExtendedPermissionForSheet: now uses a URL with &popup
- login window will check app permission for offline_access before directing user to grant offline access page
- generateSigForParameters will raise an exception if it finds nil sessionSecret or sessionKey, a message will be displayed about setting application type to desktop
- release builds will no longer log to console
The next release is planned for the end of September and will be a significant update.
