As part of our ongoing effort to improve our communication with our developer community, we offer you our latest monthly roundup of the announcements, new features, and updates to Facebook Platform that occurred during March, 2009.

New Features


  • As a reminder to our January announcement, 64-bit user IDs will start being assigned to new users in the coming days, so make sure you're storing user IDs using 64-bit integers.
  • You can submit new applications to the Application Directory if they have either 5 total users or 10 monthly active users (MAU).
  • When a user visits your canvas page (on, the page's favicon becomes that of your application.
  • fb:title now displays "<app name> on Facebook | <page name>".
