How to check if you need the upgrade for theme 2.0?

1. Click Edit code in your live theme. 

2. Search the keyword 'exat', if the search result contans the code file named exat prefix, so it is the older version. So you can upgrade to the new version. Also, you can stay in the old version if you don't need to update any of the attributes.
