OpenCart Community

I am currently running version 3.0.4.0 and am considering upgrading to version 3.0.4.1. Before proceeding, I would like to confirm whether this upgrade involves any changes to the MySQL database tables. I have made custom modifications to some of the table structures, and any changes introduced during the upgrade could potentially disrupt the functionality of my website.

There have been no changes to the database tables in 3.0.4.1 from 3.0.4.0. So you shouldn't need to run the upgrade script, just update the files.

Thank you. Do you know which files have been updated? Is it possible to update only certain files? Since my OpenCart 3.0.4.0 has undergone secondary development with additional fields added in the admin panel, I'm concerned that overwriting these files might cause the customizations to be lost. Thank you.

You can check on github but not a small task. There is no need to upgrade since the major issues have been resolved in 3.0.4.0 and it is a good version.
In future you might want to consider not making changes to core files or at the very least making notes of what you have changed. Upgrading now or in the future - the result is the same.

Well that's why vQmod and OCMOD exist so you should fire any developer who modified core files.

Who *in their right mind* still thinks modifying core files directly is a good idea?

You can see the changes between version at: https://github.com/opencart/opencart/co ... ...3.0.4.1

You will probably need to use a file comparison application to compare your files to a clean download of 3.0.4.0 to see what changes you ave made and merge them with the 3.0.4.1 or make them into a modification.

Thank you for your response. It was very helpful

You're absolutely right; that's exactly what I was considering.
