// and identical values are considered to be in the same topology.
  // We consider each <key, value> as a "bucket", and try to put balanced number
  // of pods into each bucket.
  // We define a domain as a particular instance of a topology.
  // Also, we define an eligible domain as a domain whose nodes meet the requirements of

Its type must be a <a href="#Type_definitions">defined</a> type <code>T</code> or a
pointer to a defined type <code>T</code>, possibly followed by a list of type parameter
names <code>[P1, P2, …]</code> enclosed in square brackets.
<code>T</code> is called the receiver <i>base type</i>. A receiver base type cannot be
a pointer or interface type and it must be defined in the same package as the method.

* Added `spec.additionalPrinterColumns` to CRDs to define server side printing columns. ([#60991](https://github.com/kubernetes/kubernetes/pull/60991), [@sttts](https://github.com/sttts))

- A new kubelet command line option, `--reserved-cpus`, is introduced to explicitly define the CPU list that will be reserved for system. For example, if `--reserved-cpus=0,1,2,3` is specified, then cpu 0,1,2,3 will be reserved for the system.  On a system with 24 CPUs, the user may specify `isolcpus=4-23` for the kernel option and use...

    Potential impacts:

- Updated `KMSv2` to beta ([#115123](https://github.com/kubernetes/kubernetes/pull/115123), [@aramase](https://github.com/aramase))
- Updated: Redefine AppProtocol field description and add new standard values ([#115433](https://github.com/kubernetes/kubernetes/pull/115433), [@LiorLieberman](https://github.com/LiorLieberman)) [SIG API Machinery, Apps and Network]

- Improved scheduler performance when no scoring plugins were defined.

- Improved scheduler performance when no scoring plugins were defined.

- The [Service Plan Defaults](https://svc-cat.io/docs/service-plan-defaults/) feature is in alpha and is under active development. This feature gives operators the ability to define defaults for when someone provisions a service.
- We now support [filtering which services are exposed by Service Catalog](https://svc-cat.io/docs/catalog-restrictions/).

controller manager binary. Additionally we added [aws-k8s-tester](https://github.com/kubernetes/test-infra/issues/9814), deployer interface for kubetest, to the test-infra repository. This plugin allowed us to integrate Prow to the 3 subprojects defined above in order to provide CI signal for all 3 features. The CI signal is visible [here](https://testgrid.k8s.io/) under SIG-AWS.

For detailed release notes on the three alpha features from SIG AWS, please refer to the following Changelogs:...

* Allow pods to define multiple environment variables from a whole ConfigMap ([#36245](https://github.com/kubernetes/kubernetes/pull/36245), [@fraenkel](https://github.com/fraenkel))
