- Added new option to the `InterPodAffinity` scheduler plugin to ignore existing
  pods` preferred inter-pod affinities if the incoming pod has no preferred inter-pod
  affinities. This option can be used as an optimization for higher scheduling throughput
  (at the cost of an occasional pod being scheduled non-optimally/violating existing
  pods preferred inter-pod affinities). To enable this scheduler option, set the

  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.

* 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))
