## Release Notes From SIGs

### SIG API Machinery

- The OwnerReferencesPermissionEnforcement admission plugin now checks authorization for the correct scope (namespaced or cluster-scoped) of the owner resource type. Previously, it always checked permissions at the same scope as the child resource. ([#70389](https://github.com/kubernetes/kubernetes/pull/70389), [@caesarxuchao](https://github.com/caesarxuchao))

* Adds a metric apiserver_request_error_total to kube-apiserver. This metric tallies the number of request_errors encountered by verb, group, version, resource, subresource, scope, component, and code. ([#84777](https://github.com/kubernetes/kubernetes/pull/84777), [@RainbowMango](https://github.com/RainbowMango))

- New flag is introduced, i.e. --topology-manager-scope=container|pod. 
  The default value is the "container" scope. ([#92967](https://github.com/kubernetes/kubernetes/pull/92967), [@cezaryzukowski](https://github.com/cezaryzukowski)) [SIG Instrumentation, Node and Testing]

### Bug or Regression

* Adds a metric apiserver_request_error_total to kube-apiserver. This metric tallies the number of request_errors encountered by verb, group, version, resource, subresource, scope, component, and code.  ([#83427](https://github.com/kubernetes/kubernetes/pull/83427), [@logicalhan](https://github.com/logicalhan))

  the garbage collector starts to manage it.


#### Monitoring/Prometheus

A new "scope" label is added to all apiserver_request_* values that is either 'cluster', 'resource', or 'namespace' depending on which level the query is performed at.([#52237](https://github.com/kubernetes/kubernetes/pull/52237))
