* The AWS credential provider can now obtain ECR credentials even without the AWS cloud provider or being on an EC2 instance. Additionally, AWS credential provider caching has been improved to honor the ECR credential timeout.

### Azure

- Improving the performance of Endpoint and EndpointSlice controllers by caching Service Selectors ([#84280](https://github.com/kubernetes/kubernetes/pull/84280), [@gongguan](https://github.com/gongguan))

- Avoid caching the Azure VMSS instances whose network profile is nil ([#100948](https://github.com/kubernetes/kubernetes/pull/100948), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

- For resources built into an apiserver, the server now logs at `-v=3` whether it is using watch caching. ([#109175](https://github.com/kubernetes/kubernetes/pull/109175), [@MikeSpreitzer](https://github.com/MikeSpreitzer)) [SIG API Machinery]

### Feature

- (beta feature) If the CSI driver supports the NodeServiceCapability `VOLUME_MOUNT_GROUP` and the `DelegateFSGroupToCSIDriver` feature gate is enabled, kubelet will delegate applying FSGroup to the driver by passing it to NodeStageVolume and NodePublishVolume, regardless of what other FSGroup policies are set.
