Hi,
Zend announced recently that PHP7 will be released in 2015. I've tested Jorani on Windows and Linux with today's nightly build (27th March 2015) with nginx.
So far, Jorani is fully compatible with this version (except the script requirements.php that I will fix). Please note that Jorani runs perfectly on HHVM as well.
PHP7 and HHVM can increase the performance of Jorani by a factor of 30%-70% (depending on the page being tested). While testing, I've noted a significant reduction of CPU load.
