Like XenForo 1.x itself, add-ons for XF 1.x are in support mode. This means that they will receive bug fixes until May 31st, 2019 and security updates only until December 31st, 2019. They are feature locked and no new features will be added. As of December 31, 2019 they will be End of Life and no further updates will be given after that date.
