PHP 7.1 was release couple of days back whereas Cloudways added an additional functionality that is WordPress PHP 7.1 support to ease end user and provide them facility to upgrade their existing version to PHP 7.1 without any hassle.
We all you know that, WordPress Core is fully compatible with PHP version 7 or greater. After the release of PHP 7.1 majority of the community move on to newer version because PHP 5.6 was a little slower as compared to PHP 7.1.
