`--node-cidr-mask-size-ipv6 int32`     Default: 64. Mask size for IPv6 node-cidr in dual-stack cluster.

    These 2 flags can be used only for dual-stack clusters. For non dual-stack clusters, continue to use  `--node-cidr-mask-size` flag to configure the mask size.

    The default node cidr mask size for IPv6 was 24 which is now changed to 64. ([#79993](https://github.com/kubernetes/kubernetes/pull/79993), [@aramase](https://github.com/aramase))

- The PodShareProcessNamespace feature to configure PID namespace sharing within a pod has been promoted to beta. ([#66507](https://github.com/kubernetes/kubernetes/pull/66507), [@verb](https://github.com/verb))

## API Changes

* The deprecated kubelet --configure-cbr0 flag has been removed, and with that the "classic" networking mode as well.  If you depend on this mode, please investigate whether the other network plugins `kubenet` or `cni` meet your needs. ([#34906](https://github.com/kubernetes/kubernetes/pull/34906),...

* Webhook client credentials configured with `--admission-control-config-file` must include non-default ports in the configured hostnames. For example, a webhook configured to speak to port 8443 on service `mysvc` in namespace `myns` would specify client credentials in a stanza with `name: mysvc.myns.svc:8443`. See https://kubernetes.io/docs/referen...

* promote sourceRange into service spec ([#25826](https://github.com/kubernetes/kubernetes/pull/25826), [@freehan](https://github.com/freehan))
* kube-controller-manager: Add configure-cloud-routes option ([#25614](https://github.com/kubernetes/kubernetes/pull/25614), [@justinsb](https://github.com/justinsb))

* Fix issue in converting AWS volume ID from mount paths ([#36840](https://github.com/kubernetes/kubernetes/pull/36840), [@jingxu97](https://github.com/jingxu97))
* Correct env var name in configure-helper ([#33848](https://github.com/kubernetes/kubernetes/pull/33848), [@mtaufen](https://github.com/mtaufen))

* 🔧 Update test workflow config, remove commented code. PR [#14540](https://github.com/fastapi/fastapi/pull/14540) by [@tiangolo](https://github.com/tiangolo).
* 👷 Configure coverage, error on main tests, don't wait for Smokeshow. PR [#14536](https://github.com/fastapi/fastapi/pull/14536) by [@tiangolo](https://github.com/tiangolo).

has entered beta and is available by default. You can now [configure startup, liveness, and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) for your gRPC app
natively within Kubernetes, without exposing an HTTP endpoint or
using an extra executable.

- Added a new `ServiceCIDR` type that allows to dynamically configure the cluster range used to allocate `Service ClusterIPs` addresses. ([#116516](https://github.com/kubernetes/kubernetes/pull/116516), [@aojea](https://github.com/aojea))

- 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...
