- kubeadm: promoted feature gate `EtcdLearnerMode` to GA. Learner mode in etcd deployed by kubeadm is now locked to enabled by default. ([#126374](https://github.com/kubernetes/kubernetes/pull/126374), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]

An unsuccessful call has no synchronizing effect at all.
As far as the memory model is concerned,
<code>l.TryLock</code> (or <code>l.TryRLock</code>)
may be considered to be able to return false
even when the mutex <i>l</i> is unlocked.
</p>

<h3 id="once">Once</h3>

<p>
The <code>sync</code> package provides a safe mechanism for
initialization in the presence of multiple goroutines
through the use of the <code>Once</code> type.

    intend to ship a public API for these features, but we don't want to hold OkHttp 5.0.0 until
    those APIs are stable.

 *  Fix: Change `MockWebServer.close()` to cancel ongoing calls that are blocked on a delay.

 *  Upgrade: [Okio 3.13.0][okio_3_13_0].

This release also stabilizes many APIs in the `mockwebserver3` artifact that's new in 5.0.

### Other notable changes

* Fix watch cache filtering ([#28967](https://github.com/kubernetes/kubernetes/pull/28967), [@liggitt](https://github.com/liggitt))
* Fix problems with container restarts and flocker ([#25874](https://github.com/kubernetes/kubernetes/pull/25874), [@simonswine](https://github.com/simonswine))



# v1.2.5

- GRPC probes are now a GA feature. `GRPCContainerProbe` feature gate was locked to default value and will be removed in v1.29. If you were setting this feature gate explicitly, please remove it now. ([#116233](https://github.com/kubernetes/kubernetes/pull/116233), [@SergeyKanzhelev](https://github.com/SergeyKanzhelev))

- Removed feature gates `ServiceLoadBalancerClass` and `ServiceLBNodePortControl`. These feature gates were enabled (and locked) since `v1.24`. ([#112577](https://github.com/kubernetes/kubernetes/pull/112577), [@andrewsykim](https://github.com/andrewsykim))

- If upgrading Cluster Federation components from 1.3.x, please ensure your cluster name is a valid DNS label (#30956, @nikhiljindal)

  - [beta] Deployments that cannot make progress in rolling out the newest version will now indicate via the API they are blocked ([docs](http://kubernetes.io/docs/user-guide/deployments/#failed-deployment)) ([kubernetes/features#122](https://github.com/kubernetes/enhancements/issues/122))
