Version 7 [October 7, 2021]
Version 7 contains significant changes in the internal codes and libraries. If you are updating from the previous version, update with caution, like if you have an older version of PHP, it may break your application. And before updating, create a complete backup of your files and database. We recommend, update a few days later, after we do more tests. If you are installing new, it's OK to install v7.
