How To Resolve File Conflicts After Update?

Hello,

We have CS-Cart 4.2.4 running and i'm planning to do several upgrades up to the latest version.

To test out if the updates proceed correctly, I cloned our installation and installed it on a Digital Ocean instance.

The updates proceed nicely up to 4.3.5, but I have noticed something very annoying.

Usually after I update, I resolve the file conflicts with the CS-Cart tool, where it shows you side by side with red/green markings where and what in the old file was overwritten and the newer code that was added.

Am I right that this feature is not available anymore?

What is the recommended procedure to resolve the file conflicts?

Why has this useful, almost essential feature been removed?

With kind regards,

Philip
