## Changes by Kind

### 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]

    HTTP/2 to 16 MiB of unacknowledged data per connection. With this fix there is a limit of 16 MiB
    of unacknowledged data per stream and no per-connection limit.

 *  Fix: Don't operate on a connection after it's been returned to the pool. This race occurred
    on failed web socket connection attempts.

 *  Upgrade: [Okio 3.6.0][okio_3_6_0].

 *  Upgrade: [Kotlin 1.8.21][kotlin_1_8_21].

- 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))

- The Service trafficDistribution field, including the PreferClose option, has graduated
  to GA. Services that do not have the field configured will continue to operate
  with their existing behavior. Refer to the documentation
  https://kubernetes.io/docs/concepts/services-networking/service/#traffic-distribution

* fix nil dereference when doing a volume type check on persistent volumes ([#39529](https://github.com/kubernetes/kubernetes/pull/39529), [@sjenning](https://github.com/sjenning))
* Generate OpenAPI definition for inlined types ([#39466](https://github.com/kubernetes/kubernetes/pull/39466), [@mbohlool](https://github.com/mbohlool))

* 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))
