I'm thinking that I could create a file that could be commonly pulled from outside software as well as EP4 to provide the version information instead of a database or always loaded define. That way there is no additional burden to the remainder of the site other than the existence of an additional file. Would likely place as a module file. Consider the use of

admin/includes/modules/easypopulate_4_version.php

With the processing contents of something like the existing line in the base module:
Code:
<?php
/**
 * Header related information to describe the relationship to EasyPopulate 4
 * @author mc12345678 https://mc12345678.com
 **/

$curver_detail = '4.0.36';
And then the easypopulate_4.php file where that line exists to be changed to:
Code:
require DIR_WS_MODULES . 'easypopulate_4_version.php';
