What changes made from v2.1 to v2.2?

Hello, when there is a new Version of the Theme available, is there anywhere online we can routinely view the Changelog, the description of what has been changed from the previous version, so we know what we're getting into, or what to look for that we may want to utilize? In the wp-admin section if I click "View version 2.2 details" I did not find any "Changelog" or something like that telling me what has been changed. Seems like good information to have so we can know what to be on the look-out for with a new version. Thank you for your help and nice theme.
