It's my intent to keep up with those changes and implement them in Spring Social Facebook as quickly as I can. Of course, I have other priorities as well, so I can't promise a next-day turnaround on Facebook API changes.
Fortunately, with the exception of some big-ticket items, Facebook is really good about notifying their developer community in advance of any changes that they know are coming up. They have a 90-day advance notice policy on any breaking changes, so that gives me plenty of time to react...I just have to keep up with their announcements (which I try to do weekly).
In general, if there is a breaking change to the Facebook API, I try to react to that as quickly as is reasonable...within a day or two of learning about it. If there's some new feature in the Facbeook API, I make sure to slate it for the next release. And, as always, if there's something new that's of super-importance to you, you're always welcome to open an issue in Jira to ask for it to be done sooner...I can't promise that I'll be able to do it, but if you ask I'll certainly consider it.
