Thanks Alex T⚜️

 I see PHP 5.6 (5.5.10 before 10.0.0-B1, 5.5.0 before 9.0.0-RC7) and MySQL 5.5.3 (starting from 9.0.0-RC5) What I'm asking is with UNA 11 is it safe to go with the latest versions?

  PHP 7.4.3 released on 20 Feb 2020 and as of today the latest version of MySQL is MySQL 8.0

PHP 7.4 should fine, we've added some fixes for PHP 7.4 in UNA 11
