Facebook’s recent changes have been all over the news and the Internet, and while most Facebook users won’t care about the change coming on October 1, it does effect those of us who develop Facebook Apps.
One of the big effects of this is upgrade is the change to how apps access Facebook user information, which means that all Canvas and Page tab apps must convert to process signed_request (fb_sig will be removed).
Two other things to note:
- Apps that have been built using the Facebook PHP SDK 3.1.1 do not need to be changed.
If you’re need to get working on these changes before anything breaks you can follow the steps from Facebook to make the upgrade.
