### Other notable changes

* CustomResourceDefinitions: OpenAPI v3 validation schemas containing `$ref`references are no longer permitted (valid references could not be constructed previously because property ids were not permitted either). Before upgrading, ensure CRD definitions do not include those `$ref` fields. ([#58438](https://github.com/kubernetes/kubernetes/pull/58438), [@carlory](https://github.com/carlory))

    * The new support for ORM mode fixes issues/adds features related to ORMs with lazy-loading, hybrid properties, dynamic/getters (using `@property` decorators) and several other use cases.
    * This applies to ORMs like SQLAlchemy, Peewee, Tortoise ORM, GINO ORM and virtually any other.
