- The `flowcontrol.apiserver.k8s.io/v1beta3` API version of `FlowSchema` and `PriorityLevelConfiguration` is no longer served in v1.32. Migrate manifests and API clients to use the `flowcontrol.apiserver.k8s.io/v1` API version, available since v1.29. More information is at https://kubernetes.io/docs/reference/using-api/deprecation-guide/#flowcontrol-resources-v132 ([#127017](https://gith...

- Adds "volume.beta.kubernetes.io/migrated-to" annotation to PV's and PVC's when they are migrated to signal external provisioners to pick up those objects for Provisioning and Deleting. ([#87098](https://github.com/kubernetes/kubernetes/pull/87098), [@davidz627](https://github.com/davidz627)) [SIG  Storage]

  - Ingress resources will no longer be served from `extensions/v1beta1` in v1.20. Migrate use to the `networking.k8s.io/v1beta1` API, available since v1.14. Existing persisted data can be retrieved via the `networking.k8s.io/v1beta1` API.

* There's a known issue where the Vertical Pod Autoscaler will radically change implementation in 1.12, so users of VPA (alpha) in 1.11 are warned that they will not be able to automatically migrate their VPA configs from 1.11 to 1.12.

## Consequences

* The configuration cache serialization infrastructure should be used for all serialization.
* Existing usages of Serializer outside of this infrastructure should be migrated to use it.
* Existing usages of Java serialization should be migrated to use it.
* It is ok for Serializer to be used as a replacement for Java serialization as a migration step.

* 🔨 Update internal scripts and remove unused ones. PR [#11499](https://github.com/tiangolo/fastapi/pull/11499) by [@tiangolo](https://github.com/tiangolo).
* 🔧 Migrate from Hatch to PDM for the internal build. PR [#11498](https://github.com/tiangolo/fastapi/pull/11498) by [@tiangolo](https://github.com/tiangolo).
