- Fixed cost estimation of token creation request for service account in Priority and Fairness. ([#113206](https://github.com/kubernetes/kubernetes/pull/113206), [@marseel](https://github.com/marseel))

- DRA: CEL expressions using attribute strings exceeded the cost limit because their cost estimation was incomplete. ([#129661](https://github.com/kubernetes/kubernetes/pull/129661), [@pohly](https://github.com/pohly)) [SIG Node]

## 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 runtime cost estimation for `x-int-or-string` custom resource schemas with maximum lengths. ([#132837](https://github.com/kubernetes/kubernetes/pull/132837), [@JoelSpeed](https://github.com/JoelSpeed))
