I don't always visit the forums and sometimes will miss things.
Can i suggest a newsletter or some inbox in MFP [or both] where Important Announcements like these can be sent. API change also comes to mind. Of course both would need to be optional .. opt-in for newsletter and setting for MFP Inbox.
I puzzled for a few hours before I figured out the issue. Luckily it's a holiday for me today and I had the time to troubleshoot or I would have missed all of tonight's matches.
