 - The `services.postgresql` module now sets up a systemd unit `postgresql.target`. Depending on `postgresql.target` guarantees that postgres is in read-write mode and initial/ensure scripts were executed. Depending on `postgresql.service` only guarantees a read-only connection.
 
+- The `services.mysql` module now restarts the database `on-abnormal`, which means that it now will be restarted in certain situations, it wasn't before. For example an OOM-kill.

 - The `services.siproxd` module has been removed as `siproxd` is unmaintained and broken with libosip 5.x.
 
 - `netbox-manage` script created by the `netbox` module no longer uses `sudo -u netbox` internally. It can be run as root and will change it's user to `netbox` using `runuser`
