- Introduced end-to-end tests to verify component invariant metrics across the entire test suite. ([#133394](https://github.com/kubernetes/kubernetes/pull/133394), [@BenTheElder](https://github.com/BenTheElder))
- Introduced new kubelet metrics for the Ensure Secret Pulled Images KEP, including:

*   `tf.function`/AutoGraph:
    *   AutoGraph is now available in `ReplicaContext.merge_call`,
        `Strategy.extended.update` and `Strategy.extended.update_non_slot`.
    *   Experimental support for shape invariants has been enabled in
        `tf.function`. See the API docs for
        `tf.autograph.experimental.set_loop_options` for additional info.
    *   AutoGraph error messages now exclude frames corresponding to APIs
