#### **Hardware Accelerators**

*   Kubelet now exposes metrics for NVIDIA GPUs attached to the containers. ([#55188](https://github.com/kubernetes/kubernetes/pull/55188),[ @mindprince](https://github.com/mindprince))

to those values. A type may be denoted by a <i>type name</i>, if it has one, which must be
followed by <a href="#Instantiations">type arguments</a> if the type is generic.
A type may also be specified using a <i>type literal</i>, which composes a type
from existing types.

- Improves scheduler performance when no scoring plugins are defined. ([#122058](https://github.com/kubernetes/kubernetes/pull/122058), [@aleksandra-malinowska](https://github.com/aleksandra-malinowska)) [SIG Scheduling]

* 📝 Update docs for testing, fix examples with relative imports. PR [#5302](https://github.com/tiangolo/fastapi/pull/5302) by [@tiangolo](https://github.com/tiangolo).

### Translations

* Support whitespace in command path for gcp auth plugin ([#41653](https://github.com/kubernetes/kubernetes/pull/41653), [@jlowdermilk](https://github.com/jlowdermilk))
* client-go no longer imports GCP OAuth2 and OpenID Connect packages by default. ([#41532](https://github.com/kubernetes/kubernetes/pull/41532), [@ericchiang](https://github.com/ericchiang))

* The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".  ([#30638](https://github.com/kubernetes/kubernetes/pull/30638), [@krousey](https://github.com/krousey))

    * - Don't generate empty record for externalName service.
    * - Add validation for upstreamNameserver port.
    * - Update go version to 1.9.3.
* kubectl: improves compatibility with older servers when creating/updating API objects ([#61949](https://github.com/kubernetes/kubernetes/pull/61949), [@liggitt](https://github.com/liggitt))

- The Image Locality priority function of the scheduler has been improved and is now enabled by default. With this feature enabled, nodes that have all or a partial set of images required for running a pod are preferred over other nodes, which improves pod start-up time.
- TaintNodeByCondition has been moved to Beta and is enabled by default.
- Scheduler throughput has been improved by ~50% in large clusters (>2000 nodes).

### SIG-service-catalog

- Added a counter metric `kubelet_image_manager_ensure_image_requests_total{present_locally, pull_policy, pull_required}` that exposes details about `kubelet` ensuring an image exists on the node.
