Yes you have the latest version (1.3). Although, I know Wes is redeveloping this particular theme pretty soon, so there will be a new version. Not sure when though. He’s working on updating some of the other older themes at the moment and making them new again.
He’s pretty good at keeping Themes up to date and relevant. That’s good news to people like me who have bought his themes back in 2011 🙂
