Customized Studio theme a lot...

I have customized my studio theme extensively (www.PennyPinchingDiva.com) and with the new update I would like to know exactly which files were altered/changed so that I can download the latest version of the Studio theme and only upload those certain files. I have altered several of the files to customize them to fit my layout, and I cannot imagine having to go into each file one-by-one to figure out what was altered.

Thank you in advance.
