It’s usually recommended to read the Arch news before doing an update because if there are any known issues they will be reported there. However, I’ve been using Arch now for a few years and I’ve never encountered any issues during updates (I know that others have not been so lucky. There was an update that caused grub to break for many that I recall, but I wasn’t affected by it.)
Oh, I wasn’t the person you were originally responding to. Just someone that came by later and had an answer to what I thought the question was you were asking.
