### Generic Ephemeral Volumes

- Dynamic Resource Allocation: Graduated core functionality to general availability (GA). This newly stable feature uses the _structured parameters_ flavor of DRA. ([#132706](https://github.com/kubernetes/kubernetes/pull/132706), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, Autoscaling, Etcd, Node,...

*   Code generation for CRD and User API server types is improved with the addition of two new scripts to k8s.io/code-generator: `generate-groups.sh` and `generate-internal-groups.sh`. ([#52186](https://github.com/kubernetes/kubernetes/pull/52186),[ @sttts](https://github.com/sttts))

- Removed general available feature gate `CPUManager`. ([#129296](https://github.com/kubernetes/kubernetes/pull/129296), [@carlory](https://github.com/carlory)) [SIG API Machinery, Node and Testing]

* kubeadm 1.8 now properly handles upgrades from to 1.7.x to newer release in 1.7 branch ([#53338](https://github.com/kubernetes/kubernetes/pull/53338), [@kad](https://github.com/kad))
* Add generate-groups.sh and generate-internal-groups.sh to k8s.io/code-generator to easily run generators against CRD or User API Server types. ([#52186](https://github.com/kubernetes/kubernetes/pull/52186), [@sttts](https://github.com/sttts))

- Graduated the `ReadWriteOncePod` feature gate to `GA`. ([#121077](https://github.com/kubernetes/kubernetes/pull/121077), [@chrishenzie](https://github.com/chrishenzie))
- Graduated the following kubelet resource metrics to **general availability**:
  - `container_cpu_usage_seconds_total`
  - `container_memory_working_set_bytes`
  - `container_start_time_seconds`
  - `node_cpu_usage_seconds_total`
  - `node_memory_working_set_bytes`

- Graduated pod scheduling gates to general availability.
  The `PodSchedulingReadiness` feature gate no longer has any effect, and the
  `.spec.schedulingGates` field is always available within the Pod and PodTemplate APIs. ([#123575](https://github.com/kubernetes/kubernetes/pull/123575), [@Huang-Wei](https://github.com/Huang-Wei))
- Graduated support for `minDomains` in pod topology spread constraints, to general availability.

- Added scheduler preemption support for pods using `ReadWriteOncePod` PVCs ([#114051](https://github.com/kubernetes/kubernetes/pull/114051), [@chrishenzie](https://github.com/chrishenzie))
- Added the `applyconfiguration` generator to the code-generator script that generates server-side apply configuration and client APIs ([#114987](https://github.com/kubernetes/kubernetes/pull/114987), [@astefanutti](https://github.com/astefanutti))
