Yes he made updates for Genesis 2.0. There are a lot of improvements in different places of the theme. If you haven’t changed much on your own site, I would backup what you have, and upload the new version to see if you like it better. There is a short guide on manually updating if you have made changes and don’t want to lose them here – http://appfinite.com/topic/legacy-1-3-for-genesis-2-0-html5-is-now-available/
