- Raw block volume support is promoted to beta, and enabled by default. This is accessible via the `volumeDevices` container field in pod specs, and the `volumeMode` field in persistent volume and persistent volume claims definitions. ([#71167](https://github.com/kubernetes/kubernetes/pull/71167), [@msau42](https://github.com/msau42))

- Added alpha support for ephemeral CSI inline volumes that are embedded in pod specs. ([#74086](https://github.com/kubernetes/kubernetes/pull/74086), [@vladimirvivien](https://github.com/vladimirvivien))

- The `ServiceAppProtocol` feature gate has been removed. It reached GA in Kubernetes ([#103190](https://github.com/kubernetes/kubernetes/pull/103190), [@robscott](https://github.com/robscott))

- **Volume Extension**: There are quite a few enhancements in this release that pertain to volumes and volume modifications. Volume resizing support in CSI specs is moving to beta which allows for any CSI spec volume plugin to be resizable.

### Additional Notable Feature Updates

- DRA: when asking for "All" devices on a node, Kubernetes <= 1.32 proceeded to schedule...

* Laid the groundwork for OIDC distributed claims handling in the apiserver authentication token checker. A distributed claim allows the OIDC provider to delegate a claim to a separate URL. ([ref](http://openid.net/specs/openid-connect-core-1_0.html#AggregatedDistributedClaims)). ([#63213](https://github.com/kubernetes/kubernetes/pull/63213), [@filmil](https://github.com/filmil))

  the newer `apiVersion`. ([#116299](https://github.com/kubernetes/kubernetes/pull/116299), [@pohly](https://github.com/pohly))
- `volumes`: `resource.claims` is now cleared for PVC specs during create or update of a pod spec with inline PVC template or of a PVC because it has no effect. ([#115928](https://github.com/kubernetes/kubernetes/pull/115928), [@pohly](https://github.com/pohly))

### Feature

  Ginkgo V2 doesn't accept go test's `-parallel` flags to parallelize Ginkgo specs, please switch to use `ginkgo -p` or `ginkgo -procs=N` instead. ([#109111](https://github.com/kubernetes/kubernetes/pull/109111), [@chendave](https://github.com/chendave)) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Cloud Provider,...

* Add a label which prevents a node from being added to a cloud load balancer ([#53146](https://github.com/kubernetes/kubernetes/pull/53146), [@brendandburns](https://github.com/brendandburns))
* Fixes an issue pulling pod specs referencing unqualified images from docker.io on centos/fedora/rhel ([#53161](https://github.com/kubernetes/kubernetes/pull/53161), [@dims](https://github.com/dims))

Defaulting will be available as alpha in Kubernetes 1.15 and requires structural schemas.

#### CustomResourceDefinition OpenAPI Publishing

OpenAPI specs for native types have long been served at /openapi/v2, and they are consumed by a number of components, notably kubectl client-side validation, kubectl explain and OpenAPI based client generators.
