+### Fixed
+
+- `EventbridgeClient.putEvents`: send the entry `Time` as a `Date` rather than an
+  ISO string. Under AWS SDK v3, `PutEventsCommand` rejects a string timestamp
+  with `SerializationException: STRING_VALUE can not be converted to milliseconds
+  since epoch`, so any event carrying a `time` failed since the v3 upgrade.
