Home Assistant is amazing but you really have to read the release notes for every release to make sure something you're using isn't going to break. I appreciate the improvements it has seen over the years but it's definitely not something you can just update and assume all is well.

I think it’s also lack of manual and automated testing. Few weeks ago one of the updates just broke the iOS companion app. (For everyone).

I had to rollback to my latest daily snapshot and didn’t update until they fixed it, which took around a week.
