The phpBB Group recently updated version 2.0.7 to correct a flaw in search.php, the updated release has been dubbed phpBB 2.0.7a, this is the PHP-Nuke update to match that version.
If you already updated to BBtoNuke 2.0.7 or are using PHP-Nuke 7.2 then the only files you need to replace on your site are:
search.php
login.php
and the Private Messages module's index.php
