- **Apps**
  - [stable] When replica sets cannot create pods, they will now report detail via the API about the underlying reason ([kubernetes/features#120](https://github.com/kubernetes/enhancements/issues/120))

- Promoted `NodeInclusionPolicyInPodTopologySpread` to Stable in v1.33 ([#130920](https://github.com/kubernetes/kubernetes/pull/130920), [@kerthcet](https://github.com/kerthcet)) [SIG Apps, Node, Scheduling and Testing]

### **Storage**

*   [stable] `PersistentVolume` and `PersistentVolumeClaim` objects must now have a capacity greater than zero.
*   [stable] Mutation of `PersistentVolumeSource` after creation is no longer allowed

### Volumes
* **[stable]** StorageClass API is promoted to v1 (storage.k8s.io/v1).
* **[stable]** Default storage classes are deployed during installation on Azure, AWS, GCE, OpenStack and vSphere.
* **[stable]** Added ability to populate environment variables from a configmap or secret.

  /**
   * Returns an ordering which treats all values as equal, indicating "no ordering." Passing this
   * ordering to any <i>stable</i> sort algorithm results in no change to the order of elements.
   * Note especially that {@link #sortedCopy} and {@link #immutableSortedCopy} are stable, and in
   * the returned instance these are implemented by simply copying the source list.
   *
   * <p>Example:
   *
   * {@snippet :

If you have an API that does a comparable amount of computations every time and you have a lot of clients, then the **CPU utilization** will probably *also be stable* (instead of constantly going up and down quickly).

* <a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>

These two were chosen for being fairly popular and stable, but doing a quick search, you could find dozens of alternative user interfaces for OpenAPI (that you can use with **FastAPI**).

### Flask REST frameworks { #flask-rest-frameworks }

* kubeadm will now deploy CoreDNS by default instead of KubeDNS ([#63509](https://github.com/kubernetes/kubernetes/pull/63509), [@detiber](https://github.com/detiber))
* This PR will leverage subtests on the existing table tests for the scheduler units. ([#63658](https://github.com/kubernetes/kubernetes/pull/63658), [@xchapter7x](https://github.com/xchapter7x))
    * Some refactoring of error/status messages and functions to align with new approach.
