* Renamed Kubelet metric certificate_manager_server_expiration_seconds to certificate_manager_server_ttl_seconds and changed to report the second until expiration at read time rather than absolute time of expiry. 
  * Improved accuracy of Kubelet metric rest_client_exec_plugin_ttl_seconds.

    * Potential impacts:

- Added more accurate requeueing in scheduling queue for Pods rejected by the temporal failure (e.g., temporal failure on `kube-apiserver`). ([#119105](https://github.com/kubernetes/kubernetes/pull/119105), [@sanposhiho](https://github.com/sanposhiho))

- Limit vSphere volume name to 63 characters long. ([#100404](https://github.com/kubernetes/kubernetes/pull/100404), [@gnufied](https://github.com/gnufied))
- Logging for GCE Windows clusters will be more accurate and complete when using Fluent bit. ([#101271](https://github.com/kubernetes/kubernetes/pull/101271), [@jeremyje](https://github.com/jeremyje))

* more complete and accurate logging of stack backtraces in E2E failures ([#82176](https://github.com/kubernetes/kubernetes/pull/82176), [@pohly](https://github.com/pohly))

    *   Kubelet now uses an explicit cm.GetDevicePluginResourceCapacity() function that makes it possible to more accurately determine what resources are inactive and return a more accurate view of available resources.
    *   Extends the device plugin checkpoint data to record registered resources so that we can finish resource removing devices even upon kubelet restarts.

* Report accurate status for kubernetes-master and -worker charms. ([#65187](https://github.com/kubernetes/kubernetes/pull/65187), [@kwmonroe](https://github.com/kwmonroe))
