- Added unit test helpers to validate CEL and patterns in CustomResourceDefinitions. ([#129028](https://github.com/kubernetes/kubernetes/pull/129028), [@sttts](https://github.com/sttts))

- Added memory tracking to scheduler performance tests to help detect memory leaks and monitored memory usage patterns while running `scheduler_perf`. ([#132910](https://github.com/kubernetes/kubernetes/pull/132910), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Testing]
