We have an updated release that should be available within the next week that has the updates we believe are required. The v8.0 release of JFBConnect this past Summer already had many of the updates needed to change from the older Google+ signin mechanism to their newer "Google" suite of products login.
We're not expecting many issues with the shutdown of Google+, but will be watching things closely over the next few months as the service is slowly killed off and will make any changes necessary.
Thanks,
Alex
