Actually, this is already done.
If you simply want to view files that have changed including their contents, you can use the viewer on GitHub
If you are wanting to see what changed, specifically within your own application version-to-version, I recommend using the Qcodo Updater tool. There is a “report only” mode which will generate a report of all files that will be updated with any update to Qcodo to your local codebase.
/path/to/my/cli/qcodo qcodo-updater --interaction=report-only STABLE
or
/path/to/my/cli/qcodo qcodo-updater --interaction=report-only DEVELOPMENT
The above syntax can be used to generate that report for you. Moreover, the “report” that is generated is actually a script, itself, which can be run directly to perform the updates if you wish.
