What version of the php sdk is jfbconnect using

v3.1.1, available from:
github.com/facebook/facebook-php-sdk

We have made multiple modifications to it and are using the release version from almost 11 months ago (according to their tags). We monitor the checkins and haven't seen any critical ones recently that we should roll in. There have been a few check-ins, but it's very haphazard as to what is being fixed, how much it's been tested, and whether it's recommended for a wide audience.

Hope that helps answer your question,
Alex
