At F8 in 2014, we introduced Graph API v2.0, the new Facebook Login, and a lightweight Login Review process. The goal of these changes was to give people more control over the information they share with apps. We asked all developers to upgrade their apps and go through Login Review by April 30, 2015. On that date, we'll begin upgrading all apps to Graph API v2.0 and removing access to any permissions that have not been approved via Login Review.
During the past year, many developers have already migrated their apps, and we're excited about the results:
Beginning April 30, we'll start upgrading all apps to the New Login and Graph API v2. To see if your app has been automatically upgraded, you can go to your app's Dashboard to see the oldest version of the API that your app can access.
You can also check the facebook-api-version HTTP header in all Graph API responses.
If your app hasn't been migrated yet, you can opt in to the migration at any time by updating your app's code to call Graph API v2.0, or by enabling the “Use Graph API v2.0 by default” and the "Enforce Login Review" switches in your app's settings tab, under “Migrations.” We strongly recommend upgrading by these methods, rather than waiting for the automatic upgrade, as this gives you more control over when people start seeing changes in your app.
As a reminder, when an app is upgraded, the following things will happen:
As more apps across the ecosystem upgrade to the new API and Login next week, we'd like to thank you and the entire developer community for working with us to create a better app ecosystem for people. We can't wait to see you build more awesome apps and mobile busineses with Facebook.
