I wonder if there any difference between errors.New and fmt.ErrorF?

I wonder if there any difference between errors.New and fmt.ErrorF?

I believe errors.New is marginally more efficient if the error message is static. I am not aware of any way to create a wrapped error in go apart from fmt.Errorf("%w"), however.
