- Protobuf serialization of metav1.MicroTime timestamps (used in `Lease` and `Event` API objects) has been corrected to truncate to microsecond precision, to match the documented behavior and JSON/YAML serialization. Any existing persisted data is truncated to microsecond when read from etcd. ([#111936](https://github.com/kubernetes/kubernetes/pull/111936), [@h...

* Fix issue in reconstruct volume data when kubelet restarts ([#36616](https://github.com/kubernetes/kubernetes/pull/36616), [@jingxu97](https://github.com/jingxu97))
* Ensure proper serialization of updates and creates in federation test watcher ([#36613](https://github.com/kubernetes/kubernetes/pull/36613), [@mwielgus](https://github.com/mwielgus))

    * Si no usabas FastAPI y utilizabas Starlette directamente (u otra herramienta, como Sanic, Flask, Responder, etc.) tendrías que implementar toda la validación y serialización de datos por ti mismo. Entonces, tu aplicación final aún tendría...

    * Si on n'utilisait pas FastAPI mais directement Starlette (ou un outil équivalent comme Sanic, Flask, Responder, etc) il faudrait implémenter la validation des données et la sérialisation par nous-même. Le résultat serait donc le même dans les deux cas mais du travail...

### Features

request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. If the list is complete (either because it is not chunking or because this is the last chunk), then there are no more remaining items and this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is *estimating* the size of a collection. Clients should...

Pero como los datos de TypeScript no se preservan después de la compilación a JavaScript, no puede depender de los tipos para definir validación, serialización y documentación al mismo tiempo. Debido a esto y algunas decisiones de diseño, para obtener validación, serialización y generación automática del esquema, es necesario agregar decoradores en muchos lugares. Por lo tanto, se vuelve bastante verboso.

* Protobuf serialization does not distinguish between `[]` and `null`. ([#45294](https://github.com/kubernetes/kubernetes/pull/45294), [@liggitt](https://github.com/liggitt))

- JWTs used in service account and OIDC authentication are now strictly parsed to confirm that they use compact serialization. Other encodings were not previously accepted, but would result in different unspecific errors. ([#123540](https://github.com/kubernetes/kubernetes/pull/123540), [@enj](https://github.com/enj))
