  • Issue of the topic: Upgrade mariadb server used in mySQL from its installed version of 10.0.28-MariaDB-2+b1 Raspbian testing-staging to the latest MariaDB (v10.4)

mySQl with the Maria DB server is currently running on my Openhab2 system. There are some new features in the latest Maria DB (such as lag() function) that are not in the version I have installed. I would like to take advantage of these new features but I can not find any guidance on how to upgrade the server or if would even work.
