## Changelog since v1.32.2

## Changes by Kind

### API Change

- DRA: CEL expressions using attribute strings exceeded the cost limit because their cost estimation was incomplete. Cost estimation was unnecessarily also computed in the scheduler. ([#129690](https://github.com/kubernetes/kubernetes/pull/129690), [@pohly](https://github.com/pohly)) [SIG Node]

### Bug or Regression

- 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.

   ([#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.
   ([#123562](https://github.com/kubernetes/kubernetes/pull/123562), [@jpbetz](https://github.com/jpbetz))

- 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))

- Added `SizeBasedListCostEstimate` feature gate that allowed apiserver to estimate sizes of objects to calculate cost of LIST requests. ([#132355](https://github.com/kubernetes/kubernetes/pull/132355), [@serathius](https://github.com/serathius)) [SIG API Machinery and Etcd]

- 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))
