Honor of the Queen Second Edition (Audiobook)

Hello everyone! Could you tell me if I buy the Honor of the Queen Second Edition with audible narration on amazon (https://www.amazon.com/Honor-Queen-Seco ... d+edition#) will the book include all the new content from the second edition or will it be the first version? Secondly what is exactly the new content? I have the paperback of Honor of the Queen and I am wondering if it is even worth buying? Unfortunately I could't find any info on what was changed.
