I have updated my free WordPress plugins to PHP 7 and removed support for anything lower than that. I decided they’re doing a damn fine job and there’s no reason to hold them back.
I’m not making any money from them, so I might as well force my users to upgrade their hosting platform. Or even the hosting company.
If you’re using any of my plugins, don’t forget to rate them and leave a comment. I don’t add new features, but I keep them in shape and maintain them regularly.
Another reason for the update is to make the codebase faster, slimmer and compliant with the latest WordPress wanna-be standards of removing all PHP 5 support. There’s still a long way to go, though.
