First, I need to confirm if there's a new edition of this book. Sometimes authors revise their works, adding new sections or correcting errors. I'll check online for any announcements about a revised or updated version. If there isn't a new edition, maybe the user is referring to a digital version or a newly published edition that's been converted to PDF. Even if it's not new, providing a thorough review of the second-year material in the Lovelock series would be helpful.
