This version of Patagonia Theme includes Threaded Comments. A very nice feature that was implemented in WordPress 2.7 and allows you to reply to comments and order them nicely. To activate “Threaded Comments”, just go to Settings, Discussion and check “Enable threaded (nested) comments”.
Some minor bugs were fixed to complain with new versions of Explorer and Firefox and the code was optimized. The Theme is now 100% valid CSS and XHTML. I recommend upgrading to this new version. Remember that if you downloaded a previous version of the theme and you made changes to it, make a backup of those changes, so you can apply them in the new theme.
