Head First PMP - Book


I had borrowed Head First PMP book from one of my friend (which I have heard is good in preparing for PMP exam). 

I have the book's 3rd edition : https://www.amazon.com/Jennifer-Greene-Head-First-PMP/dp/B00HTK4A5A/ref=...

But now I see that there is another latest version that is out that covers the latest 2016 changes.

Latest book: https://www.amazon.com/Head-First-PMP-Greene/dp/1449364918/ref=sr_1_1?ie...

My question is since I have starting reading from the older version do I need to buy this new version book or if there are some topics I could read on afterwards. Are there a lot of changes that wont be there in the previous versions. 

(New to pmp here)

Would appreciate inputs
