What It Does

Child Themes are used to avoid overwriting your customizations. But if you preserve a file in a child theme, then you may preserve a security risk. After an update from the parent theme, you should always check the changes and possibly add them to your child theme. This plugin helps you keep track of these changes in the parent theme.

For full usage of the plugin, your parent theme must define the version of the template file in the header of the PHP file with an additional @version info. If this is the case, you will see a warning if the version of the parent theme file is higher than your child theme file. You can also see the differences between the parent theme file and the child theme file using the wp_text_diff() function, similar to revisions.

This plugin is beneficial for theme developers and users who want to ensure their child themes are up to date with the latest changes from parent themes.
