- Improve Node QueueHint in the NodeAffinty plugin by ignoring unrelated changes that keep pods unschedulable. ([#127444](https://github.com/kubernetes/kubernetes/pull/127444), [@dom4ha](https://github.com/dom4ha)) [SIG Scheduling and Testing]

Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

        elevateWordBhv.delete(elevateWord, op -> {
            op.setRefreshPolicy(Constants.TRUE);
        });

    }

    /**
     * Sets up the condition builder for querying elevate words based on pager criteria.
     *
     * @param cb the condition builder to configure
     * @param elevateWordPager the pager containing search criteria
     */

- Improved scheduling latency when there are many gated pods and events that trigger requeueing from the unschedulable pool. ([#124618](https://github.com/kubernetes/kubernetes/pull/124618), [@gabesaba](https://github.com/gabesaba)) [SIG Scheduling and Testing]
