SUPER privilege used to allow various actions that were alternatively allowed by one of BINLOG ADMIN, BINLOG MONITOR, BINLOG REPLAY, CONNECTION ADMIN, FEDERATED ADMIN, REPL MASTER ADMIN, REPL SLAVE ADMIN, SET USER, SLAVE MONITOR. Now SUPER no longer does that, one has to grant one of the fine-grained privileges above to be to perform corresponding actions. On upgrade from MariaDB versions 10.11 and below all the privileges above are granted automatically if the user has SUPER. As a side-effect, such an upgrade will allow SUPER-user to run SHOW BINLOG EVENTS, SHOW RELAYLOG EVENTS, SHOW SLAVE HOSTS, even if he wasn't able to do it before the upgrade.
