[WP Smush Pro] Smush Pro Incompatible with PHP 7

We're in the middle of updating our servers from PHP 5.6 to PHP 7 but found that there was a compatibility issue with the Smush Pro plugin we are using on our site.
We were wondering if you could update your plugin to PHP 7 compatibility and when you believe the update will be pushed out.

Here is the result we obtained from the PHP Compatibility Checker:
