<code>B0</code> and <code>B1</code> are different because they are new types
created by distinct <a href="#Type_definitions">type definitions</a>;
<code>func(int, float64) *B0</code> and <code>func(x int, y float64) *[]string</code>
are different because <code>B0</code> is different from <code>[]string</code>;

- Kubenet: added HostPort IPv6 support.  HostPortManager: operates only with one IP family, failing if receives port mapping entries with different IP families.  HostPortSyncer: operates only with one IP family, skipping portmap entries with different IP families ([#80854](https://github.com/kubernetes/kubernetes/pull/80854), [@aojea](https://github.com/aojea))

- You can now have different operation names for different storage operations. This still prevents two operations on same volume from happening concurrently but if the operation changes, it resets the exponential backoff.

(liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet, for...

Provider now supports using Azure network resources (Virtual Network, Load Balancer, Public IP, Route Table, Network Security Group, etc.) in different AAD Tenant and Subscription than those for the Kubernetes cluster. To use the feature, please reference https://kubernetes-sigs.github.io/cloud-provider-azure/install/configs/#host-network-resources-in-different-aad-tenant-and-subscription.

* AWS cloud provider: fix support running the master with a different AWS account or even on a different cloud provider than the nodes. ([#44235](https://github.com/kubernetes/kubernetes/pull/44235), [@mrIncompetent](https://github.com/mrIncompetent))

- Resolves a performance regression in default 1.31+ configurations, related to the ConsistentListFromCache feature, where rapid create / update API requests across different namespaces encounter increased latency.

### Other (Cleanup or Flake)

- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.
  This bug causes the conformance test "HostPort validates that there is no conflict between pods with same hostPort but different hostIP and protocol" to fail. ([#98838](https://github.com/kubernetes/kubernetes/pull/98838), [@aojea](https://github.com/aojea)) [SIG Network and Node]

  * Allow configuration of a single security group for ELBs ([#45500](https://github.com/kubernetes/kubernetes/pull/45500), [@nbutton23](https://github.com/nbutton23))

  * Fix support running the master with a different AWS account or even on a different cloud provider than the nodes. ([#44235](https://github.com/kubernetes/kubernetes/pull/44235), [@mrIncompetent](https://github.com/mrIncompetent))

  `0`s, and IPv4-mapped IPv6 values (e.g. `::ffff:192.168.0.1`) are forbidden.
  These sorts of values can potentially cause security problems when different
  components interpret the same string as referring to different IP addresses
  (as in CVE-2021-29923).
  
  This tightening applies only to fields in built-in API kinds, and not to
  custom resource kinds, values in Kubernetes configuration files, or
