*   Metrics are added for monitoring admission plugins, including the new dynamic (webhook-based) ones. ([#55183](https://github.com/kubernetes/kubernetes/pull/55183),[ @jpbetz](https://github.com/jpbetz))

- Added the implementation for `PodRecreationPolicy` to wait for the creation of pods once the existing ones are fully terminated. ([#117015](https://github.com/kubernetes/kubernetes/pull/117015), [@kannon92](https://github.com/kannon92))

- Introduced new metrics removing the redundant subsystem in kube-apiserver pod logs metrics and deprecate the original ones:
  - kube_apiserver_pod_logs_pods_logs_backend_tls_failure_total becomes kube_apiserver_pod_logs_backend_tls_failure_total

* Forgiveness alpha version api definition ([#39469](https://github.com/kubernetes/kubernetes/pull/39469), [@kevin-wangzefeng](https://github.com/kevin-wangzefeng))
* Rescheduler uses taints in v1beta1 and will remove old ones (in version v1alpha1) right after its start. ([#43106](https://github.com/kubernetes/kubernetes/pull/43106), [@piosz](https://github.com/piosz))

### Volumes

* Resolves regression generating informers...

- Added `service.beta.kubernetes.io/aws-load-balancer-security-groups` annotation to set the security groups to the AWS ELB to be the only ones specified in the annotation in case this is present (does not add `0.0.0.0/0`).  ([#62774](https://github.com/kubernetes/kubernetes/pull/62774), [@Raffo](https://github.com/Raffo))

### SIG Azure

- Pod priority and preemption enables Kubernetes scheduler to schedule more important Pods first and when cluster is out of resources, it removes less important pods to create room for more important ones. The importance is specified by priority.

* PodSecurityPolicy: when multiple policies allow a submitted pod, priority is given to ones which do not require any fields in the pod spec to be defaulted. If the pod must be defaulted, the first policy (ordered by name) that allows the pod is used.

* action required: [GCP kube-up.sh] Some variables that were part of kube-env are no longer being set (ones only used for kubelet flags) and are being replaced by a more portable mechanism (kubelet configuration file). The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you...
