14/// No-op migration. All types are JSON-compatible between v79 and v80.
15/// The only change is adding new audit log event types and fields.
16///
17/// There is one exception, `AlterSetClusterV1`, which was changed in an
18/// incompatible way. We can do this only because we know this audit event has
19/// never been written before.
