#### MySQL 8
As of version 5.24 CiviCRM has been shown to be able to run on MySQL 8 through the execution of our test matrix. Not all of the Content Management Systems support MySQL 8, CiviCRM MySQL 8 support is being tracked in this [open issue for MySQL 8 support](https://lab.civicrm.org/dev/core/issues/392). It is also worth knowing that both [Backdrop](https://forum.backdropcms.org/forum/installing-backdrop-1126-mysql-8-sqlmode-cant-be-set-value-noautocreateuser) and [Drupal 7](https://www.drupal.org/project/drupal/issues/2978575) have open issues with regards to MySQL 8 support. [Drupal 8](https://www.drupal.org/docs/8/system-requirements/database-server) [supports MySQL 8 as of version 8.6](https://www.drupal.org/project/drupal/issues/2966523), Current versions of WordPress and [Joomla](https://docs.joomla.org/Joomla_and_MySQL_8) appear to be compatible with MySQL 8
