### Docs

* ✏️ Fix validation parameter name in docs, from `regex` to `pattern`. PR [#10085](https://github.com/tiangolo/fastapi/pull/10085) by [@pablodorrio](https://github.com/pablodorrio).

- CEL regex patterns in x-kubernetes-valiation rules are compiled when CRDs are created/updated if the pattern is provided as a string constant in the expression. Any regex compile errors are reported as a CRD create/update validation error. ([#108617](https://github.com/kubernetes/kubernetes/pull/108617), [@jpbetz](https://github.com/jpbetz))...

  // The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)
