Note that the default stored version remained alpha in 1.34, and whoever enabled beta during 1.34 needed to run a storage migration yourself to ensure you don't depend on alpha data in etcd.

- A new feature was enabled to improve the performance of the iptables mode of `kube-proxy` in large clusters. No action was required, however:
  

- Introducing new semantic for metric `volume_operation_total_seconds` to be the end to end latency of volume provisioning/deletion. Existing metric "storage_operation_duration_seconds" will remain untouched, however it is exposed to the following potential issues:

/proc/swaps on, set `--fail-swap-on=false`. The experimental flag `--experimental-fail-swap-on` is deprecated in this release, and will be removed in a future release.

* The `autoscaling/v2alpha1` API is now at `autoscaling/v2beta1`. However, the form of the API remains unchanged. Migrate the `HorizontalPodAutoscaler` resources to `autoscaling/v2beta1` to persist the `HorizontalPodAutoscaler` changes introduced in `autoscaling/v2alpha1`. The Horizontal Pod Autoscaler changes include support...

* The behavior of some watch calls to the server when filtering on fields was incorrect. If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent. However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version. That meant the new object was not matched by the filter. This was a regression from behavior between cached watches on the...

### OpenStack

In this cycle, SIG OpenStack focused on configuration simplification through smarter defaults and the use of auto-detection wherever feasible (Block Storage API versions, Security Groups) as well as updating API support, including:

*   Block Storage (Cinder) V3 is now supported.

* StorageClassName attribute has been added to PersistentVolume and PersistentVolumeClaim objects and should be used instead of annotation `volume.beta.kubernetes.io/storage-class`. The beta annotation is still working in this release, however it will be removed in a future release.

- Failed pods associated with a job with `parallelism = 1` are recreated by the job controller honoring exponential backoff delay again. However, for jobs with `parallelism > 1`, pods might be created without exponential backoff delay.

### Added

- The `apiserver_request_total` metric is promoted to stable status and no longer has a content-type dimensions, so any alerts/charts which presume the existence of this will fail. This is however, unlikely to be the case since it was effectively an unbounded dimension in the first place.
