- Kube-apiserver: fixed a conflict error encountered attempting to delete a pod with gracePeriodSeconds=0 and a resourceVersion precondition ([#85516](https://github.com/kubernetes/kubernetes/pull/85516), [@michaelgugino](https://github.com/michaelgugino)) [SIG API Machinery]

- The `ResourceVersion` returned in objects from delete responses is now consistent with the `ResourceVersion` contained in the delete watch event. ([#113369](https://github.com/kubernetes/kubernetes/pull/113369), [@wojtek-t](https://github.com/wojtek-t))

* Fixes an issue where the resourceVersion of an object in a DELETE watch event was not the resourceVersion of the delete itself, but of the last update to the object. This could disrupt the ability of clients clients to re-establish watches properly. ([#58547](https://github.com/kubernetes/kubernetes/pull/58547), [...

- Fixes a bug that when there is a "connection refused" error, the reflector's ListAndWatch func will return directly but what expected is that sleep 1 second and rewatch since the specified resourceVersion.

- Prevent unnecessary `Endpoints` and `EndpointSlice` updates caused by `Pod ResourceVersion` change ([#108078](https://github.com/kubernetes/kubernetes/pull/108078), [@tnqn](https://github.com/tnqn))

- Fix bug where Server Side Apply causes spurious resourceVersion bumps on no-op patches to custom resources. ([#125263](https://github.com/kubernetes/kubernetes/pull/125263), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery and Testing]

- Fixed API response for `StorageClassList` queries to return a graceful error message, if the provided `ResourceVersion` is too large. ([#132374](https://github.com/kubernetes/kubernetes/pull/132374), [@PatrickLaabs](https://github.com/PatrickLaabs)) [SIG API Machinery and Etcd]

- Resource list requests for `PartialObjectMetadata` now correctly return list metadata like the resourceVersion and the continue token. ([#75971](https://github.com/kubernetes/kubernetes/pull/75971), [@smarterclayton](https://github.com/smarterclayton))

- Enabled mTLS encryption between etcd and kube-apiserver in GCE ([#70144](https://github.com/kubernetes/kubernetes/pull/70144), [@wenjiaswe](https://github.com/wenjiaswe))
- Added `ResourceVersion` as a precondition for delete in order to ensure a delete fails if an unobserved change happens to an object. ([#74040](https://github.com/kubernetes/kubernetes/pull/74040), [@ajatprabha](https://github.com/ajatprabha))

- Kube-apiserver: fixes a 1.27+ regression in watch stability by serving watch requests without a resourceVersion from the watch cache by default, as in <1.27 (disabling the change in #115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in #115096 to serve these requests from...
