I have been looking for some kind of code release notes. I have browsed through the released notes information and through all the versions trying to find any kind of clear statement where they say which files have added, edited or deleted.
The purpose of this is that I have Custom Modules which I need to modify in order to get them working for the Magento version that I need and the release notes are useful but it does take time to have a look at each change in an attempt to get the right code written in the modules.
In my case I'm trying to go from 2.1.9 to 2.2.5.
As I said, is there anywhere I could search? If there isn't, how do you guys do it? Just looking at the error logs and the release notes and working with all of it? Thank you for your time.
