- 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]

### 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.

- Kubeadm: upgrade plan now prints a table indicating the state of known component configs prior to upgrade ([#88124](https://github.com/kubernetes/kubernetes/pull/88124), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

- Scheduler's assumed pods have 2min instead...

### **Storage**

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

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).

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.
