Looks good. A little hard to tell exactly what changes happened in the go.mod file, but it seems just some updates and removals.

Yeah, I don't like how Go updates are hard to diff. Often you can ignore the lower require section of a go.mod since they are not direct dependencies. So that's less to sift through.
