I just downloaded the latest version of Abundance, and would like to upgrade my current version, 1.3.2, but I am unsure about how to do this without completely uninstalling the current theme. I haven't done much customization of Abundance, but I have done enough that I don't really want to start over. Is there a walkthrough on how to properly update this theme?
Alternatively, can I simply replace the files listed as updated in the new version.txt file? If I ftp in to my folders and delete/replace each file will that be sufficient or will I need to hand-code some hooks within other files?
