Is there anywhere I can get a list of the files that were changed as part of the 2.7.1 upgrade?

My company was in the middle of a 2.7 upgrade when 2.7.1 came out and we have made some changes to the base code to accomidate a few changes requested by our user base. We would like to know which changes we will need to reapply after the 2.7.1 code refresh before we move forward.
