We love getting feedback from our customers on our API and improve that API to match their needs and comments.
Most recently, one of our new customers indicated that asking for both
hub.callback was redundant when removing a feed from their subscription list. This is true… if and only if the user has a single subscription to that topic.
So, starting today, it is optional to submit the
hub.callback when you unsubscribe from a feed, as long as you have a single subscription to that feed, obviously.
Of course, this change is perfectly downward compatible and compatible with the PubSubHubbub protocol as well if you use a library that implements it.
What else would you change in our API to make it easier to use?
