- Pass additional flags to subpath mount to avoid flakes in certain conditions ([#104347](https://github.com/kubernetes/kubernetes/pull/104347), [@mauriciopoppe](https://github.com/mauriciopoppe)) [SIG Storage]

* Add a way to pass extra arguments to etcd. ([#63961](https://github.com/kubernetes/kubernetes/pull/63961), [@mborsz](https://github.com/mborsz))

- E2e.test: removed the  `--viper-config` flag. If you were previously using this to pass flags to `e2e.test` via a file, you will need to pass them directly on the command line, e.g. `e2e.test --e2e-output-dir`. ([#102598](https://github.com/kubernetes/kubernetes/pull/102598), [@dims](https://github.com/dims))

In short, if you had dependencies that looked like:

```Python
def my_dep():
    try:
        yield
    except SomeException:
        pass
```

Now you need to make sure you raise again after `except`, just as you would in regular Python:

```Python
def my_dep():
    try:
        yield
    except SomeException:
        raise
```

  Noteable changes:
  1. Populate new `RuntimeHandler` field in CRI's `ImageSpec` struct during image pulls from container runtimes.
  2. Pass `runtimeHandler` field in `RemoveImage()` call to container runtime in `kubelet`'s image garbage collection. ([#121456](https://github.com/kubernetes/kubernetes/pull/121456), [@kiashok](https://github.com/kiashok))

- Callers of `wait.ExponentialBackoffWithContext` now must pass a `ConditionWithContextFunc` to be consistent with the signature and avoid creating a duplicate context. If your condition does not need a context you can use the `ConditionFunc.WithContext()` helper to ignore the context, or use `ExponentialBackoff`...

`kube-system/kubelet-config` naming scheme for the kubelet ConfigMap and RBAC rules, instead of the legacy `kubelet-config-x.yy` naming. 2) during upgrade, kubeadm will only write the new scheme ConfigMap and RBAC objects. To disable the feature you can pass `UnversionedKubeletConfigMap: false` in the kubeadm config for new clusters. For upgrade on existing clusters you can also override the behavior by patching the ClusterConfiguration object in `kube-system/kubeadm-config`. More details in the associated...
