I've only been running it for about a year (August last year) & from skimming those comments I get the impression I got in at the right time - there's a sense that they've improved stability a lot lately compared to what it was like & it may still be burdened with the fallout of reputational damage from that period.

I also perform all my updates manually - it's fully automated: a simple script that runs in seconds across my entire home server - but I don't have it on any schedule so I'm not doing anything blind. That at least affords me the luxury of being present if/when anything breaks (though for Immich that has not occurred yet).
