This is a patch release for the 0.16 line, with a single fix for coordinators that use Kubernetes ConfigMap-backed metadata.
Fixed
- The coordinator exits when it loses metadata leadership (#1157). The ConfigMap metadata leader elector can stop after losing its Kubernetes lease, but the coordinator process previously kept running — acting as a stale leader until a later metadata write happened to fail with a version conflict. The coordinator now terminates with a dedicated leadership-loss error as soon as the elector stops, letting Kubernetes restart it cleanly.
Upgrade notes
- No data migration, configuration, public API, or metrics changes.
