  - `apiserver_authentication_config_controller_last_config_info` metric after successfully loading the authentication configuration file.
  - `apiserver_authorization_config_controller_last_config_info` metric after successfully loading the authorization configuration file.

- Added a `source` label to the `resourceclaim_controller_resource_claims` metric.
  Added the `scheduler_resourceclaim_creates_total` metric for `DRAExtendedResource`. ([#134523](https://github.com/kubernetes/kubernetes/pull/134523), [@bitoku](https://github.com/bitoku)) [SIG Apps, Instrumentation, Node and Scheduling]

- `kubeproxy_conntrack_reconciler_deleted_entries_total` metric can be used to track cumulative sum of conntrack flows cleared by reconciler. ([#130204](https://github.com/kubernetes/kubernetes/pull/130204), [@aroradaman](https://github.com/aroradaman))

- Included an additional resource labeltransformation in on_operations_total metric which could be used for resource specific validations for example handling of encryption config by the apiserver.

    *   `model.add_loss(symbolic_tensor)` should work in ambient eager.
    *   Update metric name to always reflect what the user has given in compile.
        Affects following cases
    *   When name is given as 'accuracy'/'crossentropy'
    *   When an aliased function name is used eg. 'mse'
    *   Removing the `weighted` prefix from weighted metric names.
    *   Allow non-Tensors through v2 losses.
