* Added prometheus cluster monitoring addon to kube-up. ([#62195](https://github.com/kubernetes/kubernetes/pull/62195), [@serathius](https://github.com/serathius))
* Kubelet now exposes a new endpoint, `/metrics/probes`, which exposes a Prometheus metric containing the liveness and/or readiness probe results for a container. ([#61369](https://github.com/kubernetes/kubernetes/pull/61369), [@rramkumar1](https://github.com/rramkumar1))

* kubefed will now configure NodeInternalIP as the federation API server endpoint when NodeExternalIP is unavailable for federation API servers exposed as NodePort services ([#46960](https://github.com/kubernetes/kubernetes/pull/46960), [@lukaszo](https://github.com/lukaszo))

         * Lock to ensure that a task cannot be rescheduled while a cancel is ongoing.
         *
         * In theory, cancel() could execute arbitrary listeners -- bad to do while holding a lock.
         * However, we don't expose currentFuture to users, so they can't attach listeners. And the
         * Future might not even be a ListenableFuture, just a plain Future. That said, similar

- Exposed the `apiserver_watch_cache_resource_version` metric to simplify debugging problems with watchcache. ([#125377](https://github.com/kubernetes/kubernetes/pull/125377), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Instrumentation]

- Exposes and sets a default timeout for the SubjectAccessReview client for DelegatingAuthorizationOptions ([#95725](https://github.com/kubernetes/kubernetes/pull/95725), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery and Cloud Provider]

    *   ResourceVariable support for `gather_nd`.
    *   `ResourceVariable` and `Variable` no longer accepts `constraint` in the
        constructor, nor expose it as a @property.
    *   Added gradient for `SparseToDense` op.
    *   Expose a flag that allows the number of threads to vary across Python
        benchmarks.
    *   `image.resize` in 2.0 now supports gradients for the new resize kernels.
