  * Now to edit a particular API version, provide the fully-qualify the resource, version, and group used to fetch the object (for example, `job.v1.batch/myjob`)
  * Client-side conversion is no longer done, and the `--output-version` option is deprecated for `kubectl edit`.
* `edit` works as intended with apply and will not change the annotation

    * This is not really a bug in FastAPI but in Swagger UI, nevertheless pinning the version will work while a solution is found on the [Swagger UI side](https://github.com/swagger-api/swagger-ui/issues/9337).
