People who did upgrade would have found regressions in several of those versions.

We’re on 0.19.8 so just one version behind that I need to get around to updating, but before that there were a string of versions with known issues.

Lemmy is not even version 1 yet, it’s risky to update to a new version straight away.

I’d imagine it’s because it’s a hobby project for the admin. It can be a pita to keep on top of stuff like this.
