Maybe we could at least introduce an optimization of the databases from time to time. The size of the referenced "ttrss_entries" table went from an insane 1,238 MB (!) to 583 MB after optimization. The following command, maybe via a button, should to the trick: mysqlcheck -Aos --user=${MYSQL_USERNAME} --password=${MYSQL_PASSWORD} --host=${MYSQL_HOST};

@necrevistonnezr Still evaluating what is the best option to update existing installations. Most likely we won't do dist-upgrade automatically. Also, new installations will default to 18.04.
