The built-in function <code>complex</code> constructs a complex
value from a floating-point real and imaginary part, while
<code>real</code> and <code>imag</code>
extract the real and imaginary parts of a complex value.

### OpenStack
* Do not daemonize `salt-minion` for the openstack-heat provider. ([#40722](https://github.com/kubernetes/kubernetes/pull/40722), [@micmro](https://github.com/micmro))

- The "fake" clients generated by `client-gen` now have the same semantics on
  error as the real clients; in particular, a failed Get(), Create(), etc, no longer
  returns `nil`. (It now returns a pointer to a zero-valued object, like the real
  clients do.) This will break some downstream unit tests that were testing
  `result == nil` rather than `err != nil`, and in some cases may expose bugs

### Network

- Fix a string comparison bug in IPVS graceful termination where UDP real servers are not deleted. ([#78999](https://github.com/kubernetes/kubernetes/pull/78999), [@andrewsykim](https://github.com/andrewsykim))

- Kube-scheduler: fixes a 1.30 regression that can lead to a scheduler crash when processing pods with affinity that doesn't match a real/valid node ([#125039](https://github.com/kubernetes/kubernetes/pull/125039), [@AxeZhan](https://github.com/AxeZhan)) [SIG Scheduling and Testing]

    * Remove deprecated and unmaintained windows installer.  ([#58020](https://github.com/kubernetes/kubernetes/pull/58020), [@mikedanese](https://github.com/mikedanese))

    * Remove deprecated and unmaintained openstack-heat kube-up.sh.  ([#58021](https://github.com/kubernetes/kubernetes/pull/58021), [@mikedanese](https://github.com/mikedanese))

### OpenStack

- The `openstack-heat` provider for `kube-up` is deprecated and will be removed
  in a future release. Refer to Issue [#49213](https://github.com/kubernetes/kubernetes/issues/49213)
  for background information.

### Scheduling

- Kubemark now supports both real and hollow nodes in a single cluster. ([#93201](https://github.com/kubernetes/kubernetes/pull/93201), [@ellistarn](https://github.com/ellistarn)) [SIG Scalability]
