Yeah, that’s why we say so many times that you should never modify core files.
You can view the specific changes at https://core.trac.wordpress.org/log/branches/3.9?stop_rev=29383&rev=29411
Once you’re up to date, please strongly consider rolling your core hacks into plugins instead, so that you no longer have to modify the core files.
Well, a majority of my hacks are altering the naming conventions in the software… i.e; renaming wp-content, wp-content/plug-ins, and wp-includes. I don’t really know how to patch that with a plug-in.
Nothing against WP, but I prefer the world to not know my site is on the WP platform. I’m just anal about security, and it seems hackers have it out for exploiting WP sites when they find a hole in the platform. They are patched pretty quickly, but I prefer to reduce the visibility of WP on the forward-facing aspects of my site.
Anyway, I found the change log, and got everything updated. Thanks.
Have you considered http://codex.wordpress.org/Editing_wp-config.php#Moving_wp-content_folder ?
You can actually use the same trick to just re-name wp-content.
I’m not sure about wp-includes, but at least that will mean a few less core hacks. 🙂
