- XFS-filesystems are now force-formatted (option `-f`) in order to avoid problems being formatted due to detection of magic super-blocks. This aligns with the behaviour of formatting of ext3/4 filesystems. ([#104923](https://github.com/kubernetes/kubernetes/pull/104923), [@davidkarlsen](https://github.com/davidkarlsen))

ConfigMap rendering [issue](https://github.com/kubernetes/kubernetes/issues/112081) was found in the 1.25.0 release. When ConfigMaps get updated within the API, they do not get rendered to the resulting pod's filesystem by the Kubelet. The feature has been [reverted to alpha](https://github.com/kubernetes/kubernetes/pull/112078) in the 1.25.1 release.

## Urgent Upgrade Notes

### (No, really, you MUST read this before you upgrade)

has now graduated to Beta.
This allows the kubelet to dynamically retrieve credentials for a container image registry
using exec plugins, rather than storing credentials on the node's filesystem.

### Contextual Logging in Alpha

Kubernetes 1.24 has introduced [contextual logging](https://github.com/kubernetes/enhancements/issues/3077)

- Added container filesystem to the `ImageFsInfoResponse`. ([#120914](https://github.com/kubernetes/kubernetes/pull/120914), [@kannon92](https://github.com/kannon92))
