### Promoted Server Side Unknown Field Validation to Beta

- The list-type of the alpha `resourceClaims` field introduced to `Pods` in `1.26.0` was modified from `set` to `map`, resolving an incompatibility with use of this schema in `CustomResourceDefinitions` and with server-side apply. ([#114585](https://github.com/kubernetes/kubernetes/pull/114585), [@JoelSpeed](https://github.com/JoelSpeed))

- Kube-apiserver: fixes a potential crash serving CustomResourceDefinitions that combine an invalid schema and CEL validation rules. ([#126167](https://github.com/kubernetes/kubernetes/pull/126167), [@cici37](https://github.com/cici37)) [SIG API Machinery and Testing]

* `tf.lite`
    * Quantization for `FullyConnected` layer is switched from per-tensor to per-channel scales for dynamic range quantization use case (`float32` inputs / outputs and `int8` weights). The change enables new quantization schema globally in the converter and inference engine. The new behaviour can be disabled via experimental flag `converter._experimental_disable_per_channel_quantization_for_dense_layers = True`.

- Kubernetes is now built using go 1.17. ([#103692](https://github.com/kubernetes/kubernetes/pull/103692), [@justaugustus](https://github.com/justaugustus))
- Performs strict server side schema validation requests via the `fieldValidation=[Strict,Warn,Ignore]`. ([#105916](https://github.com/kubernetes/kubernetes/pull/105916), [@kevindelgado](https://github.com/kevindelgado))
- Promote `IPv6DualStack` feature to stable.

* federation: Add admission controller for policy-based placement ([#44786](https://github.com/kubernetes/kubernetes/pull/44786), [@tsandall](https://github.com/tsandall))
* Get command uses OpenAPI schema to enhance display for a resource if run with flag 'use-openapi-print-columns'.  ([#46235](https://github.com/kubernetes/kubernetes/pull/46235), [@droot](https://github.com/droot))
    * An example command:

10415         ; mapped                 ; 1043D         # 3.1  DESERET CAPITAL LETTER CHEE
10416         ; mapped                 ; 1043E         # 3.1  DESERET CAPITAL LETTER JEE
10417         ; mapped                 ; 1043F         # 3.1  DESERET CAPITAL LETTER KAY
