- DRA: scheduling pods is up to 16x faster, depending on the scenario. Scheduling throughput depends a lot on cluster utilization. It is higher for lightly loaded clusters with free resources and gets lower when the cluster utilization increases.

- Feature gate dependencies are now explicit, and validated at startup. A feature can no longer be enabled if it depends on a disabled feature. In particular, this means that `AllAlpha=true` will no longer work without enabling disabled-by-default beta features that are depended on (either with `AllBeta=true` or explicitly enumerating the disabled dependencies). ([#133697](https://github.com/kubernetes/kubernetes/pull/133697), [@tallclair](ht...

 it is likely that that selectors will remain immutable after the move to v1.
 You can continue to use code that depends on mutable selectors by calling
 the apps/v1beta1 API in this release, but you should start planning for code
 that does not depend on mutable selectors.

The major theme for the SIG OpenStack release is the work-in-progress for removing the in-tree provider. This work, being done in conjunction with SIG Cloud Provider, is focusing on moving internal APIs that the OpenStack (and other providers) depends upon to staging to guarantee API stability. This work also included abstracting the in-tree Cinder API and refactoring code to the external Cinder provider to remove additional Cinder volume provider code.

- Conformance image now depends on stretch-slim instead of debian-hyperkube-base as that image is being deprecated and removed. ([#88702](https://github.com/kubernetes/kubernetes/pull/88702), [@dims](https://github.com/dims)) [SIG Cluster Lifecycle, Release and Testing]

* ControllerRevision type has been added for StatefulSet and DaemonSet history. Clients should not depend on the stability of this type as it may change, as necessary, in future releases to support StatefulSet and DaemonSet update and rollback. We enable this type as we do with beta features, because StatefulSet update and DaemonSet update are enabled....

The merged fix enforces validation against the proxying address for a Node. In some cases, the fix can break clients that depend on the `nodes/proxy` subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane. Configuring an egress proxy for egress to the cluster network can also mitigate this vulnerability.

  Note that the default stored version remained alpha in 1.34, and whoever enabled beta during 1.34 needed to run a storage migration yourself to ensure you don't depend on alpha data in etcd.
