- Fixed the GCE firewall update when the destination IPs are changing so that firewalls reflect the IP updates of the LBs. ([#111186](https://github.com/kubernetes/kubernetes/pull/111186), [@sugangli](https://github.com/sugangli))

- Fixed indexer bug that resulted in incorrect index updates if number of index values for a given object was changing during update ([#109137](https://github.com/kubernetes/kubernetes/pull/109137), [@wojtek-t](https://github.com/wojtek-t))

For instance, <code>x / y * z</code> is the same as <code>(x / y) * z</code>.

* **Enhance Kubelet QoS**:
  * Pods are placed under a new cgroup hierarchy by default. This feature requires
    draining and restarting the node as part of upgrades. To opt-out set
    `--cgroups-per-qos=false`.
  * If `kube-reserved` and/or `system-reserved` are specified, node allocatable

* Parameterize session affinity timeout seconds in service API for Client IP based session affinity. ([#49850](https://github.com/kubernetes/kubernetes/pull/49850), [@m1093782566](https://github.com/m1093782566))
* Changing scheduling part of the alpha feature 'LocalStorageCapacityIsolation' to manage one single local ephemeral storage resource ([#50819](https://github.com/kubernetes/kubernetes/pull/50819), [@NickrenREN](https://github.com/NickrenREN))

* Update defaultbackend to 1.5: move /metrics to a private endpoint (:10254). ([#69383](https://github.com/kubernetes/kubernetes/pull/69383), [@bowei](https://github.com/bowei))
* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))

- The calculation of pod UIDs for static pods has changed to ensure each static pod gets a unique value - this will cause all static pod containers to be recreated/restarted if an in-place kubelet upgrade from 1.20 to 1.21 is performed. Note that draining pods before upgrading the kubelet across minor versions is the supported upgrade path. ([#87461](https://github.com/kubernetes/kubernetes/pull/87461), [@bboreham](https://github.com/bboreham)) [SIG Node]

* Fixed CSIDriver API object to allow missing fields. ([#69331](https://github.com/kubernetes/kubernetes/pull/69331), [@jsafrane](https://github.com/jsafrane))
* Allows changing nodeName in endpoint update. ([#68575](https://github.com/kubernetes/kubernetes/pull/68575), [@prameshj](https://github.com/prameshj))
