  N/A.Hello,It's that time of year again and time to upgrade from 1.8.6 to 1.8.7 - our forums however have a few edits, some in php files, some in the html/css, etc. Those were necessary changes that couldn't be made via plugins.I'm wondering, is there an easy way to update without losing these changing and having to apply them manually again?If not, is there an easy way to get a list of all files that have been changed from default 1.8.6, so when we update to 1.8.7 we're sure we didn't forget to add back any of the changes we made?Thank you for your help!
