temey74938 FreeFlarum will update all forums to beta.16 when most of the extensions we have available get updated to that version. The incompatible rest will be removed and re-added when the developers update them. No extension data will be lost (so you won't have to re-setup extensions that were re-added later - the data will stay in the database).
I check for extension compatibility against beta.16 frequently, and if most extensions will be compatible next weekend, we could update. Of course, in case of this extension, this solely depends on the author when and if the update will arrive. But when it does, it'll be included
