Facebook’s latest platform update includes improved insights for websites, a change in how some app stories are published to Timeline and a few breaking changes.

Insights for websites now tracks and report referrals to the underlying URL from a bit.ly link. Facebook has also added tracking and reporting for URLs within comments.

App stories published using Feed dialog or Graph API will now show in the app’s tab on a user’s Timeline, just as Open Graph actions published from an app do.

The Request 2.0 Efficient migration will be enabled for all apps in the next few days and will be set for all apps on Jan. 15.

Another breaking change effective this week is the getPageInfo method now requires a callback function and no longer returns a value synchronously.

This week’s update reminded developers that app profile pages will be deleted on Feb. 1. As we reported earlier, all traffic will be redirected to the app itself. Also on Feb. 1, the canvas_name field will be deprecated in favor of namespace field.
