* Health check parameters are configurable to be bigger than default values.
* 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))

* Conformance tests may now include disruptive tests. If you are running tests against a live cluster, consider skipping those tests tagged as `Disruptive` to avoid non-test workloads being impacted. Be aware, skipping any conformance tests (even disruptive ones) will make the results ineligible for consideration for the CNCF Certified Kubernetes program. ([#82664](https://g...

- It is now possible to combine the `-f` and `-l` flags in `kubectl logs` ([#67573](https://github.com/kubernetes/kubernetes/pull/67573), [@m1kola](https://github.com/m1kola))
- New conformance tests added for API Aggregation. ([#63947](https://github.com/kubernetes/kubernetes/pull/63947), [@jennybuckley](https://github.com/jennybuckley))

- The conformance tests:
  - Services should serve multiport endpoints from pods
  - Services should serve a basic endpoint from pods
  were only validating the API objects, not performing any validation on the actual Services implementation.

- Added e2e test to node expand volume with secret ([#115451](https://github.com/kubernetes/kubernetes/pull/115451), [@zhucan](https://github.com/zhucan))
- Added e2e tests for kubectl `--subresource` for beta graduation ([#116590](https://github.com/kubernetes/kubernetes/pull/116590), [@MadhavJivrajani](https://github.com/MadhavJivrajani))

### Failing Test

- Added mock framework support for unit tests for Windows in `kubeproxy`. ([#120105](https://github.com/kubernetes/kubernetes/pull/120105), [@princepereira](https://github.com/princepereira))

  returns `nil`. (It now returns a pointer to a zero-valued object, like the real
  clients do.) This will break some downstream unit tests that were testing
  `result == nil` rather than `err != nil`, and in some cases may expose bugs

### 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
