- E2e.test and e2e_node.test: tests which depend on alpha or beta feature gates now have `Feature:Alpha` or `Feature:Beta` as Ginkgo labels. The inline text is `[Alpha]` or `[Beta]`, as before. ([#124350](https://github.com/kubernetes/kubernetes/pull/124350), [@pohly](ht...

- e2e tests that require SSH may now be used against clusters that have nodes without external IP addresses by setting the environment variable `KUBE_SSH_BASTION` to the `host:port` of a machine that is allowed to SSH to those nodes.  The same private key that the test would use is used for the bastion host.  The test connects to the bastion and then tunnels another SSH connection to the node. ([#72286](https:...

* Make error message and service event message more clear ([#86078](https://github.com/kubernetes/kubernetes/pull/86078), [@feiskyer](https://github.com/feiskyer))
* e2e-test-framework: add e2e test namespace dump if all tests succeed but the cleanup fails. ([#85542](https://github.com/kubernetes/kubernetes/pull/85542), [@schrodit](https://github.com/schrodit))

### Windows support improved

- [Performance dashboards](http://perf-dash.k8s.io/#/?jobname=soak-tests-capz-windows-2019) added support for Windows
- [Unit tests](https://github.com/kubernetes/kubernetes/issues/51540) added support for Windows
- [Conformance tests](https://github.com/kubernetes/kubernetes/pull/108592) added support for Windows

- Service session affinity timeout tests are no longer required for Kubernetes network plugin conformance due to variations in existing implementations. New conformance tests will be developed to better express conformance in future releases. ([#112806](https://github.com/kubernetes/kubernetes/pull/112806), [@dcbw](https://github.com/dcbw)) [SIG Architecture, Network and Testing]

#### Container Runtime Interface

* Fixes segmentation fault issue with Protobuf library when log entries are deeply nested. ([#77224](https://github.com/kubernetes/kubernetes/pull/77224), [@qingling128](https://github.com/qingling128))

* Scheduling conformance tests related to daemonsets should set the annotation that relaxes node selection restrictions, if any are set. This ensures conformance tests can run on a wider array of clusters. ([#68793](https://github.com/kubernetes/kubernetes/pull/68793), [@aveshagarwal](https://github.com/aveshagarwal))

- When using the conformance test image, a new environment variable `E2E_USE_GO_RUNNER` will cause the tests to be run with the new golang-based test runner rather than the current bash wrapper.
