Starting next month, we are going to upgrade all the Wiki Replicas [0] servers from MariaDB 10.6 to MariaDB 10.11.
We don't expect any impact to users, as there are no big breaking changes in the new version. If you are curious, you can check the full list of changes on the MariaDB website. [1]
I will send an update before we start the upgrade, you can also follow the upgrade on Phabricator. [2]
