### API Change

- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek)) [SIG API Machinery]

the key was too small, but at any rate it would not open any of
them.  However, on the second time round, she came upon a low

 *  New: `ConnectionPool.setPolicy()` configures a minimum connection pool size for a target
    address. Use this to proactively open HTTP connections.

    Connections opened to fulfill this policy are subject to the connection pool's
    `keepAliveDuration` but do not count against the pool-wide `maxIdleConnections` limit.

- Fixed a 1.30.0 regression in OpenAPI descriptions of the `imagePullSecrets` and 
  `hostAliases` fields to mark the fields used as keys in those lists as either defaulted
  or required. ([#124553](https://github.com/kubernetes/kubernetes/pull/124553), [@pmalek](https://github.com/pmalek))

* Remove a release-note on multiple OpenAPI specs ([#38732](https://github.com/kubernetes/kubernetes/pull/38732), [@mbohlool](https://github.com/mbohlool))
* genericapiserver: unify swagger and openapi in config ([#38690](https://github.com/kubernetes/kubernetes/pull/38690), [@sttts](https://github.com/sttts))

* **Data te valideren**: afkomstig van elke request:
    * **Automatische foutmeldingen** te genereren die naar de client worden geretourneerd wanneer de data ongeldig is.
* De API met OpenAPI te **documenteren**:
    * die vervolgens wordt gebruikt door de automatische interactieve documentatie gebruikersinterfaces.
