+## 1.0.0-rc.4
+
+**Release date:** 2023-05-26
+
+This release candidate comes with support for Kubernetes v1.27.
+
+The `Event` API has been modified to have a dedicated key for `metadata` called
+`token`. The value of the `token` key is meant to be defined on a per event
+emitter basis for uniquely identifying the contents of the event payload.
+This key if present, is included in calculating the unique key used for rate
+limiting events.
+Furthermore, the event attributes are prefixed with an identifier to avoid
+collisions between different event attributes.
+
+In addition, a bug in the event rate limiting key calculation logic which led
+to the inconsideration of the revision specified in `.metadata` of the event has
+been fixed.
+
+Lastly, the behavior of `.spec.eventMetadata` has been modified such that if a
+key present in the map already exists in the original event's `metadata`, then
+the key in the latter takes precedence and an error log is printed for visibility.
+
