- Fix computing backoff delay when using Job pod failure policy, by including in the backoff delay calculation pod failures ignored from the backoffLimit counter.
  
  Also, compute the backoff delay more accurately for deleted pods. ([#119466](https://github.com/kubernetes/kubernetes/pull/119466), [@mimowo](https://github.com/mimowo)) [SIG Apps]

* Audit logging with buffering enabled can increase apiserver memory usage (e.g. up to 200MB in 100-node cluster). The increase is bounded by the buffer size (configurable).

### Bug or Regression

- Fix scoring for NodeResourcesMostAllocated and NodeResourcesBalancedAllocation plugins when nodes have containers with no requests. This was leaving to under-utilization of small nodes. ([#102925](https://github.com/kubernetes/kubernetes/pull/102925), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]

* Add EgressRule to NetworkPolicy ([#51351](https://github.com/kubernetes/kubernetes/pull/51351), [@cmluciano](https://github.com/cmluciano))
* Allow DNS resolution of service name for COS using containerized mounter.  It fixed the issue with DNS resolution of NFS and Gluster services. ([#51645](https://github.com/kubernetes/kubernetes/pull/51645), [@jingxu97](https://github.com/jingxu97))

- the following deprecated APIs can no longer be served:
  - All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
  - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead
  - `networkpolicies` resources under `extensions/v1beta1` - use `networking.k8s.io/v1` instead

- 'KubeSchedulerConfiguration' which used to be under GroupVersion 'componentconfig/v1alpha1',
is now under 'kubescheduler.config.k8s.io/v1alpha1'.  ([#66916](https://github.com/kubernetes/kubernetes/pull/66916), [@dixudx](https://github.com/dixudx)) Courtesy of SIG Cluster Lifecycle, SIG Scheduling, and SIG Testing

  When you enable the `KMSv2KDF` feature gate (off by default), KMS v2 uses a key derivation function to generate single use data encryption keys from a secret seed combined with some random data. This eliminates the need for a counter based nonce while avoiding nonce collision concerns associated with AES-GCM's 12 byte nonce. ([#118828](https://github.com/kubernetes/kubernetes/pull/118828), [@enj](https://github.com/enj))

 - Scheduling failures due to no nodes available are now reported as unschedulable under ```schedule_attempts_total``` metric. ([#90989](https://github.com/kubernetes/kubernetes/pull/90989), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling]

### Other (Cleanup or Flake)

* Fixes a NPD bug on GCI, so that it disables glog writing to files for log-counter ([#76211](https://github.com/kubernetes/kubernetes/pull/76211), [@wangzhen127](https://github.com/wangzhen127))
