*   Termination grace period for the calico/node add-on DaemonSet has been eliminated, reducing downtime during a rolling upgrade or deletion. ([#55015](https://github.com/kubernetes/kubernetes/pull/55015),[ @fasaxc](https://github.com/fasaxc))

- DaemonSets accept a MaxSurge integer or percent on their rolling update strategy that will launch the updated pod on nodes and wait for those pods to go ready before marking the old out-of-date pods as deleted. This allows workloads to avoid downtime during upgrades when deployed using DaemonSets. This feature is alpha and is behind the DaemonSetUpdateSurge feature gate.

- Kube-proxy handles Terminating EndpointSlices conditions and enables zero downtime deployments for Services with ExternalTrafficPolicy=Local author: @andrewsykim ([#117718](https://github.com/kubernetes/kubernetes/pull/117718), [@aojea](https://github.com/aojea)) [SIG Network, Testing and Windows]

- Reduced the number of cloud API calls and service downtime caused by excessive re-configurations of cluster LBs with externalTrafficPolicy=Local when node readiness changes (https://github.com/kubernetes/kubernetes/issues/111539). The service controller (in cloud-controller-manager) will avoid resyncing...
