- The time duration of a failed or unschedulable scheduling attempt will be longer, it 
  now includes the time duration of the unreserve operation. ([#113113](https://github.com/kubernetes/kubernetes/pull/113113), [@kerthcet](https://github.com/kerthcet))

* Don't evict static pods ([#39059](https://github.com/kubernetes/kubernetes/pull/39059), [@bprashanth](https://github.com/bprashanth))
* Provide kubernetes-controller-manager flags to control volume attach/detach reconciler sync.  The duration of the syncs can be controlled, and the syncs can be shut off as well.  ([#39551](https://github.com/kubernetes/kubernetes/pull/39551), [@chrislovecnm](https://github.com/chrislovecnm))

* Update fluentd-gcp addon to 1.28.1 ([#39706](https://github.com/kubernetes/kubernetes/pull/39706), [@ixdy](https://github.com/ixdy))
* Provide kubernetes-controller-manager flags to control volume attach/detach reconciler sync.  The duration of the syncs can be controlled, and the syncs can be shut off as well.  ([#39551](https://github.com/kubernetes/kubernetes/pull/39551), [@chrislovecnm](https://github.com/chrislovecnm))

- A new sleep action for the `PreStop` lifecycle hook was added, allowing containers to pause for a specified duration before termination. ([#119026](https://github.com/kubernetes/kubernetes/pull/119026), [@AxeZhan](https://github.com/AxeZhan))

 in your manifest. An object with a spec.selector value that does not match the labels in
 its spec.template is invalid.

 - Selector mutation is disabled for all kinds in the
 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in
 a consistent way. This restriction may be lifted in the future, but
 it is likely that that selectors will remain immutable after the move to v1.

* Add CLUSTER_SIGNING_DURATION environment variable to cluster ([#52497](https://github.com/kubernetes/kubernetes/pull/52497), [@jcbsmpsn](https://github.com/jcbsmpsn))
    * configuration scripts to allow configuration of signing duration of
    * certificates issued via the Certificate Signing Request API.

- Fix panic in JSON logging format caused by missing Duration encoder ([#101158](https://github.com/kubernetes/kubernetes/pull/101158), [@serathius](https://github.com/serathius)) [SIG API Machinery, Cluster Lifecycle and Instrumentation]

*_admission_latencies_milliseconds_summary and *_admission_latencies_milliseconds metrics because they were reporting seconds rather than milliseconds. They were also subject to multiple naming guideline violations (units should be in base units and "duration" is the best practice labelling to measure the time a request takes). Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary, as these now report the unit as described, and follow the instrumentation best practices....

* PodSecurityPolicy admission information has been added to audit logs. ([#58143](https://github.com/kubernetes/kubernetes/pull/58143), [@CaoShuFeng](https://github.com/CaoShuFeng))
* TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. ([#63999](https://github.com/kubernetes/kubernetes/pull/63999), [@mikedanese](https://github.com/mikedanese))
