    * --alpha-endpoint-reconciler-type=(master-count, lease, none) (default
    * "master-count"). The original reconciler is 'master-count'. The 'lease'
    * reconciler uses the storageapi and a TTL to keep alive an endpoint within the

    * reconciler that does not do anything. This is useful for self-hosted

* Default mount propagation has changed from "HostToContainer" ("rslave" in Linux terminology) to "None" ("private") to match the behavior in 1.9 and earlier releases. "HostToContainer" as a default caused regressions in some pods. ([#62462](https://github.com/kubernetes/kubernetes/pull/62462), [@jsafrane](https://github.com/jsafrane))

- The API server now re-uses data encryption keys while the kms v2 plugin key ID is stable.  Data encryption keys are still randomly generated on server start but an atomic counter is used to prevent nonce collisions.
