- Fixed bug where `listOfStrings.join()` in CEL expressions resulted in an unexpected internal error. ([#117593](https://github.com/kubernetes/kubernetes/pull/117593), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

- Fixed a bug that was blocking extensible error handling when serializing API responses error out. Previously, serialization failures always resulted in the status code of the original response being returned. Now, the following behavior occurs: ([#67041](https://github.com/kubernetes/kubernetes/pull/67041), [@tristanburgess](https://github.com/tristanburgess))

	    * Note: this fixes some issues with the previous implementation of metrics for disks:

	      * Time duration tracked was of the initial API call, not the entire operation.

	      * Metrics label tuple would have resulted in many independent histograms stored, one for each disk. (Did not aggregate well).

- Fixed handling of objects with invalid selectors. ([#107559](https://github.com/kubernetes/kubernetes/pull/107559), [@liggitt](https://github.com/liggitt))
- Fixed indexer bug that resulted in incorrect index updates if number of index values for a given object was changing during update ([#109137](https://github.com/kubernetes/kubernetes/pull/109137), [@wojtek-t](https://github.com/wojtek-t))

- Fix bug where `listOfStrings.join()` in CEL expressions resulted in an unexpected internal error. ([#117596](https://github.com/kubernetes/kubernetes/pull/117596), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

- Failure to start a container cannot accidentally result in the pod being considered "Succeeded" in the presence of deletion. ([#108882](https://github.com/kubernetes/kubernetes/pull/108882), [@rphillips](https://github.com/rphillips)) [SIG Node]

- Correct the calculating error in podTopologySpread plugin to avoid unexpected scheduling results. ([#112531](https://github.com/kubernetes/kubernetes/pull/112531), [@kerthcet](https://github.com/kerthcet)) [SIG Scheduling]

- Updates that remove remaining `metadata.finalizers` from  an object that is pending deletion (non-nil metadata.deletionTimestamp) and has no graceful deletion pending (nil or 0 metadata.deletionGracePeriodSeconds) now results in immediate deletion of the object. ([#77952](https://github.com/kubernetes/kubernetes/pull/77952), [@liggitt](https://github.com/liggitt))

## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

- Fix endpoint reconciler not being able to delete the apiserver lease on shutdown ([#114122](https://github.com/kubernetes/kubernetes/pull/114122), [@aojea](https://github.com/aojea)) [SIG API Machinery]
