PHP7 Compatibility

Hi, we are planning to move our hosting platform to PHP7 soon and we just did a PHP7 Check compatibility with our website.

We found this problems:

FILE: /nas/content/staging/efmplatform/wp-content/plugins/ninja-forms/deprecated/includes/admin/upgrades/upgrade-functions.php

FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE

138 | WARNING | INI directive 'safe_mode' is deprecated since PHP 5.3 and removed since PHP 5.4.

FILE: /nas/content/staging/efmplatform/wp-content/plugins/ninja-forms/deprecated/classes/step-processing.php

FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE

72 | WARNING | INI directive 'safe_mode' is deprecated since PHP 5.3 and removed since PHP 5.4.

The compatibility check is made using this plugin:

Do you think will be fixed in the next release?
Thanks for your support.
