Just received this message about outdated Facebook software/app on Cookie Connection. I believe this is an issue you all need to address, as I have not called on Facebook to use this Graph API for anything on the site. Let me know.
You can safely ignore that email; we've long since upgraded from that old version of the Facebook Graph API. Hoop.la is actually using the very latest version of the Graph API at this point (v2.9). I don't know why Facebook sends those emails out, but they apparently have a hard time detecting which version of the API people are actually using.
Hope that helps,
