This behavior can be controlled by the
[`httpmuxgo121` setting](/pkg/net/http/#ServeMux).

Go 1.22 added the [Alias type](/pkg/go/types#Alias) to [go/types](/pkg/go/types)
for the explicit representation of [type aliases](/ref/spec#Type_declarations).
Whether the type checker produces `Alias` types or not is controlled by the
[`gotypesalias` setting](/pkg/go/types#Alias).
For Go 1.22 it defaults to `gotypesalias=0`.

- The alpha feature `AnyVolumeDataSource` enables PersistentVolumeClaim objects to use the spec.dataSource field to reference a custom type as a data source ([#88636](https://github.com/kubernetes/kubernetes/pull/88636), [@bswartz](https://github.com/bswartz)) [SIG Apps and Storage]

## Changelog since v1.17.3

## Changes by Kind

### API Change

- Fixes a regression with clients prior to 1.15 not being able to update podIP in pod status, or podCIDR in node spec, against >= 1.16 API servers ([#88505](https://github.com/kubernetes/kubernetes/pull/88505), [@liggitt](https://github.com/liggitt)) [SIG Apps and Network]

### Other (Bug, Cleanup or Flake)

- github.com/moby/term: [9d4ed18 → 3f7ff69](https://github.com/moby/term/compare/9d4ed18...3f7ff69)
- github.com/opencontainers/image-spec: [v1.0.1 → v1.0.2](https://github.com/opencontainers/image-spec/compare/v1.0.1...v1.0.2)
- github.com/opencontainers/runc: [v1.0.2 → v1.1.1](https://github.com/opencontainers/runc/compare/v1.0.2...v1.1.1)

- CustomResourceDefinitions added support for marking versions as deprecated by setting `spec.versions[*].deprecated` to `true`, and for optionally overriding the default deprecation warning with a `spec.versions[*].deprecationWarning` field. ([#92329](https://github.com/kubernetes/kubernetes/pull/92329), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

- When using `kubectl replace` (or the equivalent API call) on a Service, the caller no longer needs to do a read-modify-write cycle to fetch the allocated values for `.spec.clusterIP` and `.spec.ports[].nodePort`.  Instead the API server will automatically carry these forward from the original object when the new object does not specify them.
