The current Facebook api that my old plugins and the Scirra Facebook plugin use will be expiring in 2015. With that in mind I have been creating a new plugin based on the Facebook 2.0 API. This API is the current used and is not set to expire until 2016.
More information will be coming as features are added, but if you want a sneak peak please head over to the Facebook user group at https://www.facebook.com/groups/317378255096076/#
You can also see an example here http://lancelocke.yourhosting.com/fb/
Fair warning, the plugin located at that group is a beta version. So bugs may be present(Please report them there)
