SkakashiS Would be too much work to choose between Flarum versions?
It is maybe possible, but honestly there are just so many technical things, edge cases and nuances that it’s just ultimately not worth to maintain such functionality for a free service. For instance, what happens if someone upgraded to 2.0 but then they want to go back to 1.8? The database was already migrated, does the 2.0 data just vanish? What about backups and app data, there would be multiple versions present, multiple composer dependencies to maintain, possibly multiple DB schemas(?) = more disk space taken, etc. etc.
What I’d recommend to someone who wants to remain on v1.8 (for whatever reason) is to just download the v1.8 data snapshot (from https://freeflarum.com/settings/forum_settings) and self-host it (the migration is pretty straightforward: https://docs.freeflarum.com/en/tutorials/exporting-forum/). Luckily, I’ve never heard that this would be the case for someone already: users always just accept the auto-update to latest version, most important/popular extensions always remain functional anyways
