- Fixed the following 
  -  AWS Cloud Provider attempts to delete LoadBalancer security group it didn’t provision

- The Daemonset controller creates replacements for terminal Pods, which can appear during VM preemptions or when using Pod finalizers ([#118911](https://github.com/kubernetes/kubernetes/pull/118911), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps and Testing]

- Supported `BackoffLimitPerIndex` in Jobs. ([#118009](https://github.com/kubernetes/kubernetes/pull/118009), [@mimowo](https://github.com/mimowo))
- The `IPTablesOwnershipCleanup` feature (KEP-3178) is now GA; kubelet no longer
  creates the `KUBE-MARK-DROP` chain (which has been unused for several releases)

- Added support for projected volume in describe function  ([#70158](https://github.com/kubernetes/kubernetes/pull/70158), [@WanLinghao](https://github.com/WanLinghao))
- kubeadm now automatically creates a new stacked etcd member when joining a new control plane node (does not applies to external etcd) ([#69486](https://github.com/kubernetes/kubernetes/pull/69486), [@fabriziopandini](https://github.com/fabriziopandini))

- **Federation**
  - [alpha] Creating a `Federated Ingress` is as simple as submitting
    an `Ingress` creation request to the Federation API Server. The
    Federation control system then creates and maintains a single
    global virtual IP to load balance incoming HTTP(S) traffic across
    some or all the registered clusters, across all regions. Google's
    GCE L7 LoadBalancer is the first supported implementation, and

* Fix issue in reconstruct volume data when kubelet restarts ([#36616](https://github.com/kubernetes/kubernetes/pull/36616), [@jingxu97](https://github.com/jingxu97))
* Ensure proper serialization of updates and creates in federation test watcher ([#36613](https://github.com/kubernetes/kubernetes/pull/36613), [@mwielgus](https://github.com/mwielgus))

* skip nodes that have a primary NIC in a 'Failed' provisioningState ([#65412](https://github.com/kubernetes/kubernetes/pull/65412), [@yastij](https://github.com/yastij))
* On COS, NPD creates a node condition for frequent occurrences of unregister_netdevice ([#65342](https://github.com/kubernetes/kubernetes/pull/65342), [@dashpole](https://github.com/dashpole))
