PPI was bought by another company so this may be a result of that.
I have the STERM 9th first printing and I created a support ticket a month ago complaining about not having any posted errata, they send me the 2nd printing for free and said it was the best they could do. I'd answer your question but I don't have it on me, can update later.
I can confirm.... No changes between the first and second printings were made on page 9-6
