- Pod status updates faster when reacting on probe results. The first readiness probe will be called faster when startup probes succeeded, which will make Pod status as ready faster. ([#98376](https://github.com/kubernetes/kubernetes/pull/98376), [@matthyx](https://github.com/matthyx))

* iSCSI sessions managed by kubernetes will now explicitly set startup.mode to 'manual' to  prevent automatic login after node failure recovery. This is the default open-iscsi mode, so this change will only impact users who have changed their startup.mode to be 'automatic' in /etc/iscsi/iscsid.conf. ([#57475](https://github.com/kubernetes/kubernetes/pull/57475), [@stmcginnis](https://github.com/stmcginnis))...

- Fixed bug which caused the status of Indexed Jobs to only be updated when there are newly completed indexes. The completed indexes are now updated if the .status.completedIndexes has values outside of the [0, .spec.completions> range ([#115460](https://github.com/kubernetes/kubernetes/pull/115460), [@danielvegamyhre](https://github.com/danielvegamyhre))...

    * If the serialization type is 'application/json':
    * If serialization fails, and the original status code was an failure (e.g. 4xx or 5xx), the original status code will be returned.

### Other notable changes

* GCE/Windows: disable stackdriver logging agent to prevent node startup failures ([#76099](https://github.com/kubernetes/kubernetes/pull/76099), [@yujuhong](https://github.com/yujuhong))

    * In order to safely upgrade an existing Kubernetes cluster without interruption of volume attach/detach logic:
        * First upgrade the master to Kubernetes v1.3.
            * This will start the new attach/detach controller.

- Fixed issue where there was no response or error from kubectl rollout status when there were no resources of specified kind. ([#117884](https://github.com/kubernetes/kubernetes/pull/117884), [@gxwilkerson33](https://github.com/gxwilkerson33)) [SIG CLI]

* Node status updater should SetNodeStatusUpdateNeeded if it fails to update status ([#34368](https://github.com/kubernetes/kubernetes/pull/34368), [@jingxu97](https://github.com/jingxu97))

- Node affinity, Node selectors, and tolerations are now mutable for Jobs that are suspended and have never been started ([#105479](https://github.com/kubernetes/kubernetes/pull/105479), [@ahg-g](https://github.com/ahg-g))
- Pod template annotations and labels are now mutable for Jobs that are suspended and have never been started ([#105980](https://github.com/kubernetes/kubernetes/pull/105980), [@ahg-g](https://github.com/ahg-g))

With Kubernetes 1.24, the [gRPC probes functionality](https://github.com/kubernetes/enhancements/issues/2727)
has entered beta and is available by default. You can now [configure startup, liveness, and readiness probes](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes) for your gRPC app
natively within Kubernetes, without exposing an HTTP endpoint or
using an extra executable.
