- CEL can now correctly handle a CRD `openAPIV3Schema` that has neither `Properties` nor `AdditionalProperties`. ([#121459](https://github.com/kubernetes/kubernetes/pull/121459), [@jiahuif](https://github.com/jiahuif))

- Added support for CEL(Common Expression Language) expressions and `additionalProperties` to be used under nested quantifiers in CRD schemas. ([#124381](https://github.com/kubernetes/kubernetes/pull/124381), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]

* The CRD OpenAPI v3 specification for validation now allows `additionalProperties`, which are mutually exclusive to properties. ([#62333](https://github.com/kubernetes/kubernetes/pull/62333), [@sttts](https://github.com/sttts))

## 0.99.1

### Fixes

* 🐛 Fix JSON Schema accepting bools as valid JSON Schemas, e.g. `additionalProperties: false`. PR [#9781](https://github.com/tiangolo/fastapi/pull/9781) by [@tiangolo](https://github.com/tiangolo).
