FQL has been deprecated since Graph API v2.1 (https://developers.facebook.com/docs/apps/changelog#v2_1), and will only be usable with <=v2.0 apps until October 30th 2016 (https://developers.facebook.com/docs/apps/changelog).

The Graph API has not longer the ability to retrieve the /home endpoint which contained the newsfeed, since v2.0. The only this a app can retrieve is the user's own posts.
