* The strategicmerge patchMergeKey for VolumeMounts was changed from "name" to "mountPath".  This was necessary because the name field refers to the name of the Volume, and is not a unique key for the VolumeMount.  Multiple VolumeMounts will have the same Volume name if mounting the same volume more than once.  The "mountPath" is verified to be unique and...

            Whether to load Maven extensions (such as packaging and type handlers) from
            this plugin. For performance reasons, this should only be enabled when necessary. Note: While the type
            of this field is {@code String} for technical reasons, the semantic type is actually
            {@code Boolean}. Default value is {@code false}.

- The `SupportNodePidsLimit` feature is now beta, and enabled by default.  It is no longer necessary to set the feature gate `SupportNodePidsLimit=true`. ([#76221](https://github.com/kubernetes/kubernetes/pull/76221), [@RobertKrawitz](https://github.com/RobertKrawitz))

- Revised scheduling behavior to correctly handle nominated node changes. Trigger rescheduling of pods 
if necessary when pods with nominated node names got deleted or nominated on a different node. ([#129058](https://github.com/kubernetes/kubernetes/pull/129058), [@dom4ha](https://github.com/dom4ha)) [SIG Scheduling, Storage and Testing]

- DRA: when the scheduler had to deallocate a claim after a node became unsuitable for a pod, it might have needed more attempts than really necessary. This was fixed by first disabling allocations. ([#120428](https://github.com/kubernetes/kubernetes/pull/120428), [@pohly](https://github.com/pohly))

- Dynamic Resource Allocation (DRA): in the `pod.spec.recourceClaims` array, the `source` indirection is no longer necessary. Instead of e.g. `source: resourceClaimTemplateName: my-template`, one can write `resourceClaimTemplateName: my-template`.

  2. If you were previously overriding the kube-proxy configuration for performance reasons, this may no longer be necessary.
