- `client-go`: Improved memory use of reflector caches when watching large numbers
  of objects which do not change frequently. ([#113362](https://github.com/kubernetes/kubernetes/pull/113362), [@sxllwx](https://github.com/sxllwx))

- DRA kubelet: the kubelet now also cleans up ResourceSlices in some additional failure scenarios (driver gets removed forcibly or crashes and does not restart). ([#132058](https://github.com/kubernetes/kubernetes/pull/132058), [@pohly](https://github.com/pohly)) [SIG Node and Testing]

- Kubelet no longer crashes when a DRA driver returns a nil as part of the Node(Un)PrepareResources response instead of an empty struct (did not affect drivers written in Go, first showed up with a driver written in Rust). ([#124091](https://github.com/kubernetes/kubernetes/pull/124091),...

- The EndpointSlice controller now waits for EndpointSlice and Node caches to be synced before starting. ([#94086](https://github.com/kubernetes/kubernetes/pull/94086), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- Fixes a regression that could cause panics in LRU caches in controller-manager, kubelet, kube-apiserver, or client-go EventSourceObjectSpamFilter ([#104469](https://github.com/kubernetes/kubernetes/pull/104469), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster...

* Improved **correctness** in corner cases.
* **Safer** types.
* Better **performance** and **less energy** consumption.
* Better **extensibility**.
* etc.

...all this while keeping the **same Python API**. In most of the cases, for simple models, you can simply upgrade the Pydantic version and get all the benefits. 🚀
