- The `v1` version of `LeaderMigrationConfiguration` supports only `leases` API for leader election. To use formerly supported mechanisms, please continue using `v1beta1`.

### Bug or Regression

- Added Coordinated Leader Election as Alpha under the `CoordinatedLeaderElection` feature gate. With the feature enabled, the control plane can use LeaseCandidate objects (coordination.k8s.io/v1alpha1 API group) to participate in a leader election and let the kube-apiserver select the best instance according to some strategy.
