CC and php 8.1 in Technical Help Posted October 26, 2022 1 hour ago, bsmither said: I would NOT apply the diff file to the filediff program. Guaranteed to result in a hot mess. No no. I have notes of what files have been changed in the skin. I will run DiffMerge on each of them and carefully update the code on the new CC version skin. I have very clear remarks on every change. I just need to carefully examine the code between the old and new to make sure I understand any changes in the new that may affect my modifications. It is slow and tedious. And, as I said, I have to think. Hate that.
