The reason I ask for support to MariaDB 10 in addition to performance 40% better also about the future compatibility. MariaDB 5.5 is too old and very old 2012. Many changes were done mariadb10 and have to readjust from version 5.5.
If we do not start from now to use the latest software, it will be a pain in the future. As it is now, MariaDB 5.5 can not immediately to version 10.1.x need to MariaDB version 10 in advance. Now mariadb10.2.3 beta is out, it will be a lot of steps to upgrade. version v5.5 and then v5.5.50 - v10 - v10.1 - v10.2 - v10.2.3. I've tried a fresh install and upgrade but webmin can not read MariaDB-10.
Hopefully virtualmin could follow, because some of the control panel is already using the latest version of MariaDB-10.1.30.
