- Made Job controller batching of syncJob invocations enabled unconditionally (it was conditional on JobReadyPods feature before).

- The `ServiceAccountIssuerDiscovery` feature gate is removed. It reached GA in Kubernetes 1.21. ([#103685](https://github.com/kubernetes/kubernetes/pull/103685), [@mengjiao-liu](https://github.com/mengjiao-liu))
- The `constants/variables` from k8s.io for STABLE metrics is now supported. ([#103654](https://github.com/kubernetes/kubernetes/pull/103654), [@coffeepac](https://github.com/coffeepac))

* In case kubeadm can't access the current Kubernetes version remotely and fails to parse the git-based version it falls back to a static predefined value of k8s.io/kubernetes/cmd/kubeadm/app/constants.CurrentKubernetesVersion. ([#72454](https://github.com/kubernetes/kubernetes/pull/72454), [@rojkov](https://github.com/rojkov))

### Other (Cleanup or Flake)

- Client-go header logging (at verbosity levels >= 9) now masks `Authorization` header contents ([#95316](https://github.com/kubernetes/kubernetes/pull/95316), [@sfowl](https://github.com/sfowl)) [SIG API Machinery]

### Changed

- Added `optionalOldSelf` to `x-kubernetes-validations` to support ratcheting CRD schema constraints. ([#121034](https://github.com/kubernetes/kubernetes/pull/121034), [@alexzielenski](https://github.com/alexzielenski))

* Use online nodes instead of possible nodes when discovering available NUMA nodes ([#83196](https://github.com/kubernetes/kubernetes/pull/83196), [@zouyee](https://github.com/zouyee))
* Fix typos in `certificates.k8s.io/v1beta1` KeyUsage constant names: `UsageContentCommittment` becomes `UsageContentCommitment` and `UsageNetscapSGC` becomes `UsageNetscapeSGC`. ([#82511](https://github.com/kubernetes/kubernetes/pull/82511), [@abursavich](https://github.com/abursavich))

* Fixed OpenAPI Description and Nickname of API objects with subresources ([#49357](https://github.com/kubernetes/kubernetes/pull/49357), [@mbohlool](https://github.com/mbohlool))
* set RBD default values as constant vars ([#49274](https://github.com/kubernetes/kubernetes/pull/49274), [@dixudx](https://github.com/dixudx))

- Pod spread constraints have been added in alpha. You can use these constraints to control how Pods are spread across the cluster among failure-domains. ([#77327](https://github.com/kubernetes/kubernetes/pull/77327), [#77760](https://github.com/kubernetes/kubernetes/pull/77760), [#77828](https:/...

  termination message log file. The termination message file is now properly
  readable for end users and has a maximum size (4k bytes) to prevent abuse.
  Each pod may have up to 12k bytes of termination messages before the contents
  of each will be truncated.
* Do not delete pod objects until all its compute resource footprint has been
  reclaimed.
  - This feature prevents the node and scheduler from oversubscribing resources
