  - Added `allocatedResources` field to container status in pod status that describes the node resources allocated to a pod.
  - Added `resources` field to container status that reports actual resources applied to running containers.
  - Added `resize` field to pod status that describes the state of a requested pod resize.

- Kubeadm: Set the `seccompProfile` to `runtime/default` in the `PodSecurityContext` of the control-plane components that run as static Pods. ([#100234](https://github.com/kubernetes/kubernetes/pull/100234),...

- A static pod that is rapidly updated was failing to start until the Kubelet was restarted. ([#107900](https://github.com/kubernetes/kubernetes/pull/107900), [@smarterclayton](https://github.com/smarterclayton))

- Track the number of Pods with a Ready condition in Job status. The feature is alpha and needs the feature gate JobReadyPods to be enabled. (#104915, @alculquicondor) [SIG API Machinery, Apps, CLI and Testing]

### Feature

- [`KT-58980`](https://youtrack.jetbrains.com/issue/KT-58980) K2: Import of java field from companion's base breaks the compiler
- [`KT-59140`](https://youtrack.jetbrains.com/issue/KT-59140) K2: "Symbol public final static field is invisible" caused by java static field called in kotlin code
- [`KT-59501`](https://youtrack.jetbrains.com/issue/KT-59501) Escape analysis constructs arrays of negative size

- Kubeadm: make sure the etcd static pod startup probe uses /health?serializable=false while the liveness probe uses /health?serializable=true&exclude=NOSPACE. The NOSPACE exclusion would allow administrators to address space issues one member at a time.

* Kubelet considers all static pods as critical. Static pods pass kubelet admission even if a node does not have enough resources. Users must ensure that they account for resources when creating static pods. ([#80491](https://github.com/kubernetes/kubernetes/pull/80491), [@hpandeycodeit](https://github.com/hpandeycodeit))

- 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),...

* On cluster provision or upgrade, kubeadm now generates certs and secures all connections to the etcd static-pod with mTLS. This includes the etcd serving cert, the etcd peer cert, and the apiserver etcd client cert. Flags and hostMounts are added to the etcd and apiserver static-pods to load these certs. For connections to etcd, https is now used in favor of http. ([#57415](https://github.com/kubernetes/kubernetes/pull/57415), [@stealth...
