As of version 2020.1, Connect ships with version 8.0.18, but this is only installed if you’re doing a fresh install. If you are upgrading from a previous version, you’d need to uninstall, remove the old database, then reinstall to obtain the latest version of mySQL
Note that starting with the upcoming version 2022.1 of OL Connect, we will be shipping MariaDB instead of MySQL. You will still be able to use MySQL if you prefer, of course.
Does this mean that MariaDB is what will be installed with OL Connect packages from now on and Oracle MySQL will no longer be upgraded through this packages?
