this is just to make sure whether this info from the plugin pages are up to date:
the STACK plugin page shows STACK is ok with moodle up to 3.6 (3.5 recommended),
the associated plugins like qbehaviour_dfexplicitvaildate are ok with up to 3.5,
both moodle version do not allow PHP 7.3 (officially)
the reason I am asking is that other server software requires PHP 7.3 minimum,
so are there any plans of validating STACK and associated plugins for moodle 3.7+?
