if the official, commercial servers can't avoid this, what more could I do? I can't even provide redundancy.
on top of that, we run vaultwarden at work. both times this year compatibility was fucked up by a client update, me and my colleagues had to completely reset the client because it bugged away so hard.
All you need to do is set up watchtower along with vaultarden and you'll always be up to date.
sounds like a horrible idea with any software. patch versions could be fine, perhaps, but vaultwarden does not follow semver.
