- Improved PVC Protection Controller's scalability by batch-processing PVCs by namespace with lazy live pod listing. ([#125372](https://github.com/kubernetes/kubernetes/pull/125372), [@hungnguyen243](https://github.com/hungnguyen243)) [SIG Apps, Node, Storage and Testing]

- The scheduler now retries Pods, which are failed by `nodevolumelimits` due to not found PVCs, only when new PVCs are added. ([#121952](https://github.com/kubernetes/kubernetes/pull/121952), [@sanposhiho](https://github.com/sanposhiho))

- Added scheduler preemption support for pods using `ReadWriteOncePod` PVCs ([#114051](https://github.com/kubernetes/kubernetes/pull/114051), [@chrishenzie](https://github.com/chrishenzie))

- It introduces a new scope name `VolumeAttributesClass`. 
  
  It matches all PVC objects that have the volume attributes class mentioned. 
  

- Stopped expanding PVCs annotated with node-expand-not-required. ([#131907](https://github.com/kubernetes/kubernetes/pull/131907), [@gnufied](https://github.com/gnufied)) [SIG API Machinery, Etcd, Node, Storage and Testing]

## Changelog since v1.8.10

### Action Required

* ACTION REQUIRED: In-place node upgrades to this release from versions 1.7.14, 1.8.9, and 1.9.4 are not supported if using subpath volumes with PVCs.  Such pods should be drained from the node first. ([#61373](https://github.com/kubernetes/kubernetes/pull/61373), [@msau42](https://github.com/msau42))

### Other notable changes

- Added a feature gate `StatefulSetAutoDeletePVC`, which allows PVCs automatically created for StatefulSet pods to be automatically deleted. ([#99728](https://github.com/kubernetes/kubernetes/pull/99728), [@mattcary](https://github.com/mattcary))

- Add `DataSourceRef` alpha field to PVC spec, which allows contents other than `PVCs` and `VolumeSnapshots` to be data sources. ([#103276](https://github.com/kubernetes/kubernetes/pull/103276), [@bswartz](https://github.com/bswartz))

- The AnyVolumeDataSource feature is now beta, and the feature gate is enabled by default. In order to provide user feedback on PVCs with data sources, deployers must install the VolumePopulators CRD and the data-source-validator controller. ([#108736](https://github.com/kubernetes/kubernetes/pull/108736), [@bswartz](https://github.com/bswartz))
