I received this from developers.facebook:
Once you have confirmed your app is compliant or unaffected by the July 2013 Breaking Changes, set the migration setting to “Enabled” in the Advanced section of the App Dashboard. This will apply the July 2013 Breaking Changes to your app and prevent you from receiving future alerts about these changes.
MyWP WPMU, is currently using the following deprecated features:
Non-threaded comments. Please see the developer roadmap for more details about this change.
These changes will be permanently enabled for all apps in 16 days on Wednesday, July 10, 2013.
Here is what the developers page says about this:
We are deprecating the ‘comments’ field from ‘stream’ FQL table. Please select the ‘comment_info’ column to fetch the ‘can_comment’ and ‘comment_count’ fields (formerly called ‘can_post’ and ‘count’:wink:, and use the comment table directly to retrieve the list of comments.
Do I need to do anything about this?
Thank you,
Peter
