Just curios how to do this. I have built my site upon the Leviathan theme and I have customized it quite heavily. i.e. modified its files, and where needed copied over a template from the parent theme and modified it to suit my need.
now I see 0.1.3 is out while I was using 0.1.2
a) is there a change log?
b) any hints on how to proceed if I need the upgrade?
