([#122558](https://github.com/kubernetes/kubernetes/pull/122558), [@linxiulei](https://github.com/linxiulei))
- Fixed CEL estimated cost for expressions that perform operations on the result of `map()` operations (e.g., `.map(...).exists(...)` ) to have the correct estimated cost instead of an unbounded cost.

- Kubeadm: during execution of the "check expiration" command, treat the etcd CA as external if there is a missing etcd CA key file (etcd/ca.key) and perform the proper validation on certificates signed by the etcd CA. Additionally, make sure that the CA for all entries in the output table is included - for both certificates on disk and in kubeconfig files. ([#106923](https://github.com/kubernetes/kub...
