I had to look into the changelog to see what they meant but it’s not too intrusive IMO [1]. That being said, I find it way easier using calibre-web-automated [2]. Everything is through a web server, has usual control, and syncs with Kobo. All it takes in one docker compose and you’re up in less than 10 minutes.
