- Added `ImageMaximumGCAge` field to Kubelet configuration, which allows a user to set the maximum age an image is unused before it's garbage collected. ([#121275](https://github.com/kubernetes/kubernetes/pull/121275), [@haircommander](https://github.com/haircommander))

  - scheduler_e2e_scheduling_duration_seconds replaced by scheduler_scheduling_attempt_duration_seconds ([#115209](https://github.com/kubernetes/kubernetes/pull/115209), [@dgrisonnet](https://github.com/dgrisonnet))
- Removed unused rule for `nodes/spec` from `ClusterRole` `system:kubelet-api-admin` ([#113267](https://github.com/kubernetes/kubernetes/pull/113267), [@hoskeri](https://github.com/hoskeri))

- Fixed an issue where eviction manager was not deleting unused images or containers. ([#127874](https://github.com/kubernetes/kubernetes/pull/127874), [@AnishShah](https://github.com/AnishShah))

- The `IPTablesOwnershipCleanup` feature (KEP-3178) is now GA; kubelet no longer
  creates the `KUBE-MARK-DROP` chain (which has been unused for several releases)
  or the `KUBE-MARK-MASQ` chain (which is now only created by kube-proxy). ([#119374](https://github.com/kubernetes/kubernetes/pull/119374), [@danwinship](https://github.com/danwinship))

- The unused `series.state` field, deprecated since v1.14, is removed from the `events.k8s.io/v1beta1` and `v1` Event types. ([#90449](https://github.com/kubernetes/kubernetes/pull/90449), [@wojtek-t](https://github.com/wojtek-t)) [SIG Apps]
