PHP 7 compatibility?

Hi there, I see this plugin hasn’t been updated in a while, so I’m not sure if this message is getting through to anyone, or if it’s been dropped?

Anyway, running the PHP 7 Compatibility checker by WP Engine I see errors on this plugin. Will these be fixed? Can they be ignored?

Here they are:
