Database driver & version after server upgrade The server I'm running Craft installations on just got an upgrade to Ubuntu 20 with MariaDB 10.5 Before MySql 5.7 was used.
When I look at the System Report in the Craft CP, it says: Database driver &amp; version    MySQL 5.5.5
When I look at phpMyAdmin it says: &quot;Server-Version: 10.5.6-MariaDB-1:10.5.6+maria~focal-log - mariadb.org binary distribution&quot;
Why is it showing MySQL 5.5.5 in the System Report?
MariaDB is a &quot;drop-in&quot; replacement for MySQL and Craft/PHP/PDO treats them as identical 99.99% of the time.
Craft gets the information about which database/version is being used directly from PDO and since there isn't a specific MariaDB PDO driver, the MySQL is used and that is what is reported back.
