- 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))

- The `apiserver` exposes 4 new metrics that allow to track the status of the Service CIDRs allocations:
      - current number of available IPs per Service CIDR
      - current number of used IPs per Service CIDR
      - total number of allocation per Service CIDR
      - total number of allocation errors per ServiceCIDR ([#104119](https://github.com/kubernetes/kubernetes/pull/104119), [@aojea](https://github.com/aojea))

- `k8s.io/dynamic-resource-allocation/controller:` `UnsuitableNodes` can now handle a mix of allocated and unallocated claims correctly. ([#120338](https://github.com/kubernetes/kubernetes/pull/120338), [@pohly](https://github.com/pohly))

	// a start and end unless there is an implicit end.
	Range string
	// A byte array representing the serialized state of a range allocation. Additional clarifiers on
	// the type or format of data should be represented with annotations. For IP allocations, this is
	// represented as a bit array starting at the base IP of the CIDR in Range, with each bit representing

- 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))

* IPAM controller unifies handling of node pod CIDR range allocation. ([#51374](https://github.com/kubernetes/kubernetes/pull/51374), [@bowei](https://github.com/bowei))
    * It is intended to supersede the logic that is currently in range_allocator
    * and cloud_cidr_allocator. (ALPHA FEATURE)
    * Note: for this change, the other allocators still exist and are the default.
    * It supports two modes:
