- [E2E] Pods spawned by E2E tests can now pull images from the private registry using the new --e2e-docker-config-file flag ([#114625](https://github.com/kubernetes/kubernetes/pull/114625), [@Divya063](https://github.com/Divya063)) [SIG Node and Testing]

- 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))

### Testing

- e2e storage tests now run faster and are easier to read ([#72434](https://github.com/kubernetes/kubernetes/pull/72434), [@pohly](https://github.com/pohly))

- The e2e suite can be instructed not to wait for pods in kube-system to be ready or for all nodes to be ready by passing `--allowed-not-ready-nodes=-1` when invoking the e2e.test program. This allows callers to run subsets of the e2e suite in scenarios other than perfectly healthy clusters. ([#98781](https://github.com/kubernetes/kubernetes/pull/98781), [@smarterclay...

    *   histograms stored, one for each disk. (Did not aggregate well).
* Update kubernetes-e2e charm to use snaps ([#45044](https://github.com/kubernetes/kubernetes/pull/45044), [@Cynerva](https://github.com/Cynerva))
* Log the error (if any) in e2e metrics gathering step ([#45039](https://github.com/kubernetes/kubernetes/pull/45039), [@shyamjvs](https://github.com/shyamjvs))

* test/e2e/e2e.test: ([#69105](https://github.com/kubernetes/kubernetes/pull/69105), [@pohly](https://github.com/pohly))
   * -viper-config can be used to set also the options defined by command line flags

- The image `gcr.io/kubernetes-e2e-test-images` will no longer be used in E2E / CI testing, `k8s.gcr.io/e2e-test-images` will be used instead. ([#103724](https://github.com/kubernetes/kubernetes/pull/103724), [@claudiubelu](https://github.com/claudiubelu))

- Feature gate `ProbeTerminationGracePeriod` is enabled by default. ([#108541](https://github.com/kubernetes/kubernetes/pull/108541), [@kerthcet](https://github.com/kerthcet))

## Known Issues
- volumeDevices mapping ignored when container is privileged

- Replaced deprecated package `k8s.io/utils/pointer` with `k8s.io/utils/ptr` for ./test/e2e and ./test/utils. ([#132763](https://github.com/kubernetes/kubernetes/pull/132763), [@PatrickLaabs](https://github.com/PatrickLaabs)) [SIG Autoscaling and Testing]
