Facebook on its Developers blog also announced that on March 9, 2012, they'll begin turning on the enhanced "auth dialog" to new users for all apps, which includes new button text and provides added functionality to the publish_actions permission.
"To ensure a clear experience for your users with this new dialog, be sure to add the updated image and text through the Developer App," posted Lu Chen on Facebook Developers blog.
In the enhanced auth dialog, the button text will be one of four cases: "Add to Facebook", "Log in with Facebook", "Go to App", or "Play Game".
"The enhanced auth dialog will launch to 5% of an app's incoming new users next Friday, and roll out more broadly in the coming weeks. You can opt to accelerate this roll out to 100% of your incoming new users by enabling "Enhanced Auth Dialog" in the advanced settings within the Developer App. Asking for publish_actions will also turn on the new dialog for 100% of new users, for apps that are not categorized as games," explains Chen.
Adding, "We'll also add some of the most frequently requested permissions to publish_actions to make the permission more robust and improve conversion. publish_actions now includes the ability to post status updates on the authenticated user's own timeline, tag photos, publish photos and videos. Other actions such as posting to a friend's timeline still require the use of publish_stream," said Chen.
