+===================
+## Highlights
+
+This patch release fixes a bug causing `applier` and `Controller` to deadlock when too many Kubernetes object change events were ingested at once. All users of `applier` and `Controller` are encouraged to upgrade as quickly as possible. Older versions are also affected, this bug is believed to have existed since the original release of `kube_runtime`.
