* Fixes v1.17.0 regression in --service-cluster-ip-range handling with IPv4 ranges larger than 65536 IP addresses ([#86534](https://github.com/kubernetes/kubernetes/pull/86534), [@liggitt](https://github.com/liggitt))

* When using IP aliases, use a secondary range rather than subnetwork to reserve cluster IPs. ([#51690](https://github.com/kubernetes/kubernetes/pull/51690), [@bowei](https://github.com/bowei))
* IPAM controller unifies handling of node pod CIDR range allocation. ([#51374](https://github.com/kubernetes/kubernetes/pull/51374), [@bowei](https://github.com/bowei))

- Fix an issue that pods using hostNetwork keep increasing. ([#67456](https://github.com/kubernetes/kubernetes/pull/67456), [@Huang-Wei](https://github.com/Huang-Wei))
- fixes an out of range panic in the NoExecuteTaintManager controller when running a non-64-bit build ([#65596](https://github.com/kubernetes/kubernetes/pull/65596), [@liggitt](https://github.com/liggitt))

objects now support a `MayRunAs` rule for `fsGroup` and `supplementalGroups` options. This allows specifying ranges of allowed GIDs for pods/containers without forcing a default GID the way `MustRunAs` does. This means that a container to which such a policy applies to won't use any fsGroup/supplementalGroup GID if not explicitly specified, yet a specified GID must still fall in the GID range according to the policy.

### Provider-specific Notes

#### Various

   Core changes:

  * Support for load balancers with source ranges

#### AWS

Core changes:

  * Support for ELBs with complex configurations: better subnet selection with
multiple subnets, and internal ELBs
  * Support for VPCs with private dns names

* When creating a service with annotation: service.beta.kubernetes.io/load-balancer-source-ranges containing multiple source ranges and service.beta.kubernetes.io/azure-shared-securityrule: "false",  the NSG rules will be collapsed.

### Promoted endPort in Network Policy to Stable

Promoted `endPort` in [Network Policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/#targeting-a-range-of-ports) to GA. Network Policy providers that support `endPort` field now can use it to specify a range of ports to apply a Network Policy. Previously, each Network Policy could only target a single port.

* Update Dashboard UI version to 1.4.2 ([#35895](https://github.com/kubernetes/kubernetes/pull/35895), [@rf232](https://github.com/rf232))
* Add support for service load balancer source ranges to Azure load balancers. ([#36696](https://github.com/kubernetes/kubernetes/pull/36696), [@brendandburns](https://github.com/brendandburns))
