- Fix a bug that Pods could stuck in the unschedulable pod pool 
  if they're rejected by PreEnqueue plugins that could change its result by a change in resources apart from Pods.
  
  DRA plugin is the only plugin that meets the criteria of the bug in in-tree, 
  and hence if you have `DynamicResourceAllocation` feature flag enabled, 

- Fixed a bug with dual stack clusters using the beta feature MultiCIDRServiceAllocator which could not create dual stack Services or Services with IPs in the secondary range. Users who wanted to use this feature in version 1.30 with dual stack clusters could work around the issue by setting the feature gate DisableAllocatorDualWrite to true.

### Serverside Apply - Beta 2

- The scheduling queue didn't notice any extenders' failures, it could miss some cluster events,
  and it could end up Pods rejected by Extenders stuck in unschedulable pod pool in 5min in the worst-case scenario.

- LeaseLocks could now have custom labels that different holders would overwrite when they became the holder of the underlying lease. ([#131632](https://github.com/kubernetes/kubernetes/pull/131632), [@DerekFrank](https://github.com/DerekFrank))
