## Changelog since v1.27.5

## Changes by Kind

### API Change

- Fixed a bug where CEL expressions in CRD validation rules would incorrectly compute a high estimated cost for functions that return strings, lists or maps.

- The `controller.kubernetes.io/pod-deletion-cost` annotation can be set to offer a hint on the cost of deleting a `Pod` compared to other pods belonging to the same ReplicaSet. Pods with lower deletion cost are deleted first. This is an alpha feature. ([#99163](https://github.com/kubernetes/kubernetes/pull/99163), [@ahg-g](https://github.com/ahg-g))

- Fixed a bug where CEL expressions in CRD validation rules would incorrectly compute a high estimated cost for functions that return strings, lists or maps.

- Kube-controller-manager: volume plugins can be restricted from contacting local and loopback addresses by setting `--volume-host-allow-local-loopback=false`, or from contacting specific CIDR ranges by setting `--volume-host-cidr-denylist` (for example, `--volume-host-cidr-denylist=127.0.0.1/28,feed::/16`) ([#91785](https://github.com/kubernetes/kubernetes/pull/91785), [@mattcary](https://github.com/mattcary)) [SIG API Machinery, Apps, Auth, CLI,...

  - The `ValidateProxyRedirects` feature was promoted to Beta and enabled by default. This feature restricts redirect-following from the apiserver to same-host redirects.  If nodes are configured to respond to CRI streaming requests on a different host interface than what the apiserver makes requests on (only the case if not using the built-in dockershim & setting the kubelet flag `--redirect-container-streaming=true`), then these requests will be broken....

* Configurable etcd compaction frequency in GCE ([#59106](https://github.com/kubernetes/kubernetes/pull/59106), [@wojtek-t](https://github.com/wojtek-t))
* [GCE] Apiserver uses `InternalIP` as the most preferred kubelet address type by default. ([#59019](https://github.com/kubernetes/kubernetes/pull/59019), [@MrHohn](https://github.com/MrHohn))

- Added CEL runtime cost calculation into CustomerResource validation. CustomerResource validation will fail if runtime cost exceeds the budget. ([#108482](https://github.com/kubernetes/kubernetes/pull/108482), [@cici37](https://github.com/cici37))
