strpos() warning for DUD Alpha Links Scroll

I’ve been noticing this warning message from my admin screen when updating WordPress. Wondering if it will be addressed in a future update:

Deprecated: strpos(): Non-string needles will be interpreted as strings in the future. Use an explicit chr() call to preserve the current behavior in /[server]/wordpress/wp-content/plugins/dynamic-user-directory-alpha-links-scroll/plugin-update-checker-4.2/Puc/v4p4/Plugin/Package.php on line 167
