 The first argument is the receiver's service name. It might have been created by
 your ``transports`` configuration or it can be your own receiver.
 It also requires a ``--bus`` option in case you have multiple buses configured,
 which is the name of the bus to which received messages should be dispatched.
 
+.. versionadded:: 4.3
+
+    The ``messenger:consume`` command was renamed in Symfony 4.3 (previously it
+    was called ``messenger:consume-messages``).
