### **Cluster Lifecycle**

*   kube-apiserver: `--ssh-user` and `--ssh-keyfile` are now deprecated and will be removed in a future release. Users of SSH tunnel functionality in Google Container Engine for the Master -> Cluster communication should plan alternate methods for bridging master and node networks. ([#54433](https://github.com/kubernetes/kubernetes/pull/54433),[ @dims](https://github.com/dims))

- When initializing nodes using external cloud-providers, the process now waits for the providerID value to be available before declaring the node ready. This ensures that nodes are not marked as Ready prematurely due to communication errors with the cloud-provider. The providerID and zone labels are necessary for integrations such as load balancers to function correctly. Users can choose to opt out of this behavior by setting the feature flag OptionalProviderID in the clou...

- Kubeadm: Added the `HTTPEndpoints` field to `ClusterConfiguration.Etcd.ExternalEtcd` to configure HTTP endpoints for etcd communication in v1beta4. This separates HTTP traffic (e.g., `/metrics`, `/health`) from gRPC traffic, improving access control. Mirrors etcd’s `--listen-client-http-urls` behavior; if not set, the `Endpoints` field handles both traffic types. ([#134890](ht...

- Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))

Container'larla çalışırken, onları başlatıp yönettiğiniz sistem; bu **load balancer**'dan (aynı zamanda **TLS Termination Proxy** de olabilir) uygulamanızın bulunduğu container(lar)a **network communication**'ı (ör. HTTP request'leri) iletmek için zaten dahili araçlar sunar.

* Ignore pods marked for deletion that exceed their grace period in ResourceQuota ([#46542](https://github.com/kubernetes/kubernetes/pull/46542), [@derekwaynecarr](https://github.com/derekwaynecarr))
* kubelet to master communication when doing node status updates now has a timeout to prevent indefinite hangs ([#52176](https://github.com/kubernetes/kubernetes/pull/52176), [@liggitt](https://github.com/liggitt))

* Update to go 1.12.10 ([#83139](https://github.com/kubernetes/kubernetes/pull/83139), [@cblecker](https://github.com/cblecker))
* Resolves bottleneck in internal API server communication that can cause increased goroutines and degrade API Server performance ([#80465](https://github.com/kubernetes/kubernetes/pull/80465), [@answer1991](https://github.com/answer1991))

* Ensure euqiv hash calculation is per schedule ([#59245](https://github.com/kubernetes/kubernetes/pull/59245), [@resouer](https://github.com/resouer))

* Upped the timeout for apiserver communication in the juju kubernetes-worker charm. ([#59219](https://github.com/kubernetes/kubernetes/pull/59219), [@hyperbolic2346](https://github.com/hyperbolic2346))
