### gRPC Probes Graduate to Beta

With Kubernetes 1.24, the [gRPC probes functionality](https://github.com/kubernetes/enhancements/issues/2727)
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

### Feature

- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... 

- Ensure health probes are created for local traffic policy UDP services on Azure ([#84802](https://github.com/kubernetes/kubernetes/pull/84802), [@feiskyer](https://github.com/feiskyer))

* Fixes a bug in kubeadm that caused init and join to hang indefinitely in specific conditions. ([#85156](https://github.com/kubernetes/kubernetes/pull/85156), [@chuckha](https://github.com/chuckha))
* Ensure health probes are created for local traffic policy UDP services on Azure ([#84802](https://github.com/kubernetes/kubernetes/pull/84802), [@feiskyer](https://github.com/feiskyer))

* fix azure load balancer update dns label issue ([#85329](https://github.com/kubernetes/kubernetes/pull/85329), [@nilo19](https://github.com/nilo19))
* Ensure health probes are created for local traffic policy UDP services on Azure ([#85328](https://github.com/kubernetes/kubernetes/pull/85328), [@nilo19](https://github.com/nilo19))



# v1.14.9

[Documentation](https://docs.k8s.io)

  
  In addtion, please be careful that:
  - controller-manager MUST start with `--authorization-kubeconfig` and `--authentication-kubeconfig` correctly set to get authentication/authorization working.
  - liveness/readiness probes to controller-manager MUST use HTTPS now, and the default port has been changed to 10257.

* azure: update disk lock logic per vm during attach/detach to allow concurrent updates for different nodes. ([#85115](https://github.com/kubernetes/kubernetes/pull/85115), [@aramase](https://github.com/aramase))
* Ensure health probes are created for local traffic policy UDP services on Azure ([#85327](https://github.com/kubernetes/kubernetes/pull/85327), [@nilo19](https://github.com/nilo19))

### API Change

- We have added a new Priority & Fairness rule that exempts all probes (/readyz, /healthz, /livez) to prevent 
  restarting of "healthy" kube-apiserver instance(s) by kubelet. ([#101114](https://github.com/kubernetes/kubernetes/pull/101114), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]
