<h3 id="Complex_numbers">Manipulating complex numbers</h3>

<p>
Three functions assemble and disassemble complex numbers.
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.

- CEL regex patterns in x-kubernetes-valiation rules are compiled when CRDs are created/updated if the pattern is provided as a string constant in the expression. Any regex compile errors are reported as a CRD create/update validation error. ([#108617](https://github.com/kubernetes/kubernetes/pull/108617), [@jpbetz](https://github.com/jpbetz))

metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script [from a commit message](https://github.com/kubernetes/kubernetes/pull/112043/commits/dfdf88d4faafa6fd39988832ea0ef6d668f490e9) to update that code.

* Implementers of the cloud provider interface will note the addition of a context to this interface. Trivial code modification will be necessary for a cloud provider to continue to compile. ([#59287](https://github.com/kubernetes/kubernetes/pull/59287), [@cheftako](https://github.com/cheftako))

* kubectl built for darwin from darwin now enables cgo to use the system-native C libraries for DNS resolution. Cross-compiled kubectl (e.g. from an official kubernetes release) still uses the go-native netgo DNS implementation.

- Migrated scheduler files `comparer.go`, `dumper.go`, `node_tree.go` to structured logging ([#105968](https://github.com/kubernetes/kubernetes/pull/105968), [@shivanshu1333](https://github.com/shivanshu1333)) [SIG Instrumentation and Scheduling]

* etcd version 3.0.17

* Go version: 1.8.3. [Link to announcement](https://groups.google.com/d/msg/kubernetes-dev/0XRRz6UhhTM/YODWVnuDBQAJ)

    * Kubernetes can only be compiled with Go 1.8. Support for all other versions is dropped.
