* Fixes issue where subpath volume content was deleted during orphaned pod cleanup for Local volumes that are directories (and not mount points) on the root filesystem. ([#72291](https://github.com/kubernetes/kubernetes/pull/72291), [@msau42](https://github.com/msau42))

* Update cadvisor to v0.23.9 to fix a problem where attempting to gather container filesystem usage statistics could result in corrupted devicemapper thin pool storage for Docker. ([#30307](https://github.com/kubernetes/kubernetes/pull/30307), [@sjenning](https://github.com/sjenning))



# v1.3.5

- Improved the `FreeDiskSpaceFailed` warning event to provide more actionable details when image garbage collection fails to free enough disk space. Example: `Insufficient free disk space on the node's image filesystem (95.0% of 10.0 GiB used). Failed to free sufficient space by deleting unused images. Consider resizing the disk or deleting unused files.`. ([#132578](https://github.com/kubernetes/kubernetes/pull/132578), [@drigz](https://github.com/drigz))

*   Added pod-level local ephemeral storage metric to the Summary API. Pod-level ephemeral storage reports the total filesystem usage for the containers and emptyDir volumes in the measured Pod. ([#55447](https://github.com/kubernetes/kubernetes/pull/55447),[ @jingxu97](https://github.com/jingxu97))

#### **Hardware Accelerators**

* Rename ScheduledJobs to CronJobs. ([#36021](https://github.com/kubernetes/kubernetes/pull/36021), [@soltysh](https://github.com/soltysh))
* Read the federation controller manager kubeconfig from a filesystem path ([#30601](https://github.com/kubernetes/kubernetes/pull/30601), [@madhusudancs](https://github.com/madhusudancs))

  - More information [here](https://vishh.github.io/docs/user-guide/gpus/).
* A pod’s Quality of Service Class is now available in its Status.
* Upgrade cAdvisor library to v0.25.0. Notable changes include,
  - Container filesystem usage tracking disabled for device mapper due to excessive
    IOPS.
  - Ignore `.mount` cgroups, fixing disappearing stats.
* A new field `terminationMessagePolicy` has been added to containers that allows

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.
