- Reduced memory usage/allocations during wait for volume attachment. ([#126575](https://github.com/kubernetes/kubernetes/pull/126575), [@Lucaber](https://github.com/Lucaber)) [SIG Node and Storage]

- Creates an annotation `service.beta.kubernetes.io/aws-load-balancer-eip-allocations` to assign AWS EIP to the newly created Network Load Balancer. Number of allocations and subnets must match. ([#69263](https://github.com/kubernetes/kubernetes/pull/69263), [@brooksgarrett](https://github.com/brooksgarrett))

- Fix unsafe JSON construction in a number of locations in the codebase ([#81158](https://github.com/kubernetes/kubernetes/pull/81158), [@zouyee](https://github.com/zouyee))

         * That could change behavior if the input maps use different equivalence relations (and so
         * a key that appears once in `right` might appear multiple times in `left`). We don't
         * guarantee behavior in that case, anyway, and the current behavior is likely undesirable.

- Introduced a breaking change to the `resource.k8s.io` API in its `AllocationResult` struct. This change allows a kubelet plugin for the `DynamicResourceAllocation` feature to service allocations from multiple resource driver controllers. ([#116332](https://github.com/kubernetes/kubernetes/pull/116332), [@klueska](https://github.com/klueska))

- Kubeadm: avoid panicing if the user has malformed the kubeconfig in the cluster-info config map to not include a valid current context. Include proper validation at the appropriate locations and throw errors instead.
