- A static pod that is rapidly updated was failing to start until the Kubelet was restarted. ([#107900](https://github.com/kubernetes/kubernetes/pull/107900), [@smarterclayton](https://github.com/smarterclayton))

failures and now perform a more rigorous reconciliation to ensure static pods (especially those that use fixed UIDs) are restarted.  As a side effect of these changes static pods will be restarted with lower latency than before (2s vs 4s, on average) and rapid updates to pod configuration should take effect sooner.
  
  A new metric `kubelet_known_pods` has been added at ALPHA stability to report the number of pods a Kubelet is tracking in a number of internal states.  Operators may use the metrics...

### SIG Cluster Lifecycle

  * kubeadm: The `:Etcd` struct has been refactored in the v1alpha2 API. All the options now reside under either `.Etcd.Local` or `.Etcd.External`. Automatic conversions from the v1alpha1 API are supported. ([#64066](https://github.com/kubernetes/kubernetes/pull/64066), [@luxas](https://github.com/luxas))

- Print go stack traces at -v=4 and not -v=2 ([#94663](https://github.com/kubernetes/kubernetes/pull/94663), [@soltysh](https://github.com/soltysh)) [SIG CLI]
- Recreate EndpointSlices on rapid Service creation. ([#94730](https://github.com/kubernetes/kubernetes/pull/94730), [@robscott](https://github.com/robscott))

#### DaemonSet
* [beta] DaemonSet supports history and rollback. See [Performing a Rollback on a DaemonSet](https://kubernetes.io/docs/tasks/manage-daemon/rollback-daemon-set/).

- Resolves a performance regression in default 1.31+ configurations, related to the ConsistentListFromCache feature, where rapid create / update API requests across different namespaces encounter increased latency. ([#130136](https://github.com/kubernetes/kubernetes/pull/130136), [@AwesomePatrol](https://github.com/AwesomePatrol)) [SIG API Machinery]

* StatefulSet: Fix to fully preserve restart and termination order when StatefulSet is rapidly scaled up and down. ([#45113](https://github.com/kubernetes/kubernetes/pull/45113), [@kow3ns](https://github.com/kow3ns))

- Fix endpoints status out-of-sync when the pod state changes rapidly ([#125675](https://github.com/kubernetes/kubernetes/pull/125675), [@tnqn](https://github.com/tnqn)) [SIG Apps, Network and Testing]

- Fix endpoints status out-of-sync when the pod state changes rapidly ([#125675](https://github.com/kubernetes/kubernetes/pull/125675), [@tnqn](https://github.com/tnqn)) [SIG Apps, Network and Testing]

- NONE ([#97167](https://github.com/kubernetes/kubernetes/pull/97167), [@geegeea](https://github.com/geegeea)) [SIG Node]
