* Fixes issue with cleaning up stale NFS subpath mounts ([#71804](https://github.com/kubernetes/kubernetes/pull/71804), [@msau42](https://github.com/msau42))
* Modify the scheduling result struct and improve logging for successful binding. ([#71926](https://github.com/kubernetes/kubernetes/pull/71926), [@wgliang](https://github.com/wgliang))

            ALICE'S RIGHT FOOT, ESQ.
                HEARTHRUG,
                    NEAR THE FENDER,
                        (WITH ALICE'S LOVE).

Oh dear, what nonsense I'm talking!'

  Just then her head struck against the roof of the hall:  in
fact she was now more than nine feet high, and she at once took
up the little golden key and hurried off to the garden door.

  Poor Alice!  It was as much as she could do, lying down on one

* Mark image as deliberately optional in v1 Container struct.  Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set. ([#48406](https://github.com/kubernetes/kubernetes/pull/48406), [@gyliu513](https://github.com/gyliu513))

# Release 2.5.0

## Major Features and Improvements

*   Support for Python3.9 has been added.
*   `tf.data`:
    *   `tf.data` service now supports strict round-robin reads, which is useful
        for synchronous training workloads where example sizes vary. With strict
        round robin reads, users can guarantee that consumers get similar-sized
        examples in the same step.

- `klog` text output now uses JSON as encoding for structs, maps and slices. ([#117687](https://github.com/kubernetes/kubernetes/pull/117687), [@pohly](https://github.com/pohly))
- `kube-proxy` in iptables mode will now have separate `sync_full_proxy_rules_duration_seconds`\nand

- Introduced a breaking change to the `resource.k8s.io` API in its `AllocationResult` struct. This change allows a kubelet plugin for the `DynamicResourceAllocation` feature to service allocations from multiple resource driver controllers. ([#116332](https://github.com/kubernetes/kubernetes/pull/116332), [@klueska](https://github.com/klueska))...

- Promoted meta.k8s.io/v1beta1 Table and PartialObjectMetadata to v1. ([#77136](https://github.com/kubernetes/kubernetes/pull/77136), [@smarterclayton](https://github.com/smarterclayton))

- The `PodDeletionCost` feature has been promoted to beta, and enabled by default. ([#101080](https://github.com/kubernetes/kubernetes/pull/101080), [@ahg-g](https://github.com/ahg-g))
- The `Server Side Apply` treats certain structs as atomic. Meaning the entire selector field is managed by a single writer and updated together. ([#100684](https://github.com/kubernetes/kubernetes/pull/100684), [@Jefftree](https://github.com/Jefftree))

- Fixed scheduling of **CronJob** with `@every X` schedules. ([#109250](https://github.com/kubernetes/kubernetes/pull/109250), [@d-honeybadger](https://github.com/d-honeybadger))
- Fixed strict server-side field validation treating `metadata` fields as unknown fields. ([#109268](https://github.com/kubernetes/kubernetes/pull/109268), [@liggitt](https://github.com/liggitt))
