Yup. We test our releases with the latest releases of Joomla, CB, and all other extensions we integrate with. You shouldn't run into any issues with that combination, but if you do, we're here to help.
If you have any other questions, let us know!
If you use our extensions, please consider leaving a rating and review at the Joomla! Extension Directory: JFBConnect | SCLogin
