- 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))...

- Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. ([#73892](https://github.com/kubernetes/kubernetes/pull/73892), [@smarterclayton](https://github.com/smarterclayton))

- Persistent Volumes formatted with the btrfs filesystem will now automatically resize when expanded. ([#99361](https://github.com/kubernetes/kubernetes/pull/99361), [@Novex](https://github.com/Novex)) [SIG Storage]

- Fix formatting of assorted go API deprecations for godoc / pkgsite and enable a linter to help catch mis-formatted deprecations ([#133571](https://github.com/kubernetes/kubernetes/pull/133571), [@BenTheElder](https://github.com/BenTheElder)) [SIG API Machinery, Architecture, CLI, Instrumentation and Testing]

    * A sample cloud provider configure is: '{"vmType": "vmss", "useInstanceMetadata": true}'.
* Volumes specified in a pod but not used in it are no longer unnecessarily formatted, mounted and reported in `node.status.volumesInUse`. ([#81163](https://github.com/kubernetes/kubernetes/pull/81163), [@jsafrane](https://github.com/jsafrane))
