- `EphemeralContainers`: Enable the ability to add {{< glossary_tooltip text="ephemeral containers"
term_id="ephemeral-container" >}} to running pods.
- `EvenPodsSpread`: Enable pods to be scheduled evenly across topology domains. See [Pod Topology Spread Constraints](/docs/concepts/workloads/pods/pod-topology-spread-constraints/).
- `ExecProbeTimeout`: Ensure kubelet respects exec probe timeouts. This feature gate exists in case any of your existing workloads depend on a now-corrected fault where Kubernetes ignored exec probe timeouts. See [readiness probes](/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes).
- `ExpandInUsePersistentVolumes`: Enable expanding in-use PVCs. See [Resizing an in-use PersistentVolumeClaim](/docs/concepts/storage/persistent-volumes/#resizing-an-in-use-persistentvolumeclaim).
- `ExpandPersistentVolumes`: Enable the expanding of persistent volumes. See [Expanding Persistent Volumes Claims](/docs/concepts/storage/persistent-volumes/#expanding-persistent-volumes-claims).
- `ExperimentalCriticalPodAnnotation`: Enable annotating specific pods as *critical* so that their [scheduling is guaranteed](/docs/tasks/administer-cluster/guaranteed-scheduling-critical-addon-pods/).
