* Enhance CNI plugin compatibility, supports flannel, calico, weave and so on.
  * Pass all CRI validation conformance tests and node end-to-end conformance tests.
  * Add experimental Unikernel support.

* [alpha] [cri-containerd](https://github.com/kubernetes-incubator/cri-containerd): CRI implementation for containerd is now v1.0.0-alpha.0, [[@Random-Liu](https://github.com/Random-Liu)]

* Third Party Resource tests in the e2e suite were incorrectly marked as part of the conformance bucket.  They are alpha and are not required for conformance. ([#52823](https://github.com/kubernetes/kubernetes/pull/52823), [@smarterclayton](https://github.com/smarterclayton))

    *   Added ARM64 release. Upgraded to CNI 0.6.0, added block device as Pod volume mode. Fixed CNI plugin compatibility.
    *   Passed all CRI validation conformance tests and node end-to-end conformance tests.
*   [alpha] [rktlet](https://github.com/kubernetes-incubator/rktlet): CRI implementation for the rkt runtime is now v0.1.0. [[@iaguis](https://github.com/iaguis)]

* 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))

- kubeadm: support fetching configuration from the original cluster for `upgrade diff` ([#80025](https://github.com/kubernetes/kubernetes/pull/80025), [@SataQiu](https://github.com/SataQiu))

- Edit your code and remove the import reference.
- Run `go mod tidy` in the source folder to remove dependency from `go.mod` file.

### What are the coding guidelines for MinIO?

* Java compilation of Gradle code suffers from small performance penalty (up to 10%).
* Time has to be allocated to clean up existing projects.
* One has to write NullAway-conformant code even when hacking.
* Some patterns used to satisfy NullAway can be slightly more verbose.

* StatefulSet controllers no longer force a resync every 30 seconds when nothing has changed. ([#75622](https://github.com/kubernetes/kubernetes/pull/75622), [@jonsabo](https://github.com/jonsabo))
* Ensures the conformance test image saves results before exiting when ginkgo returns non-zero value. ([#76039](https://github.com/kubernetes/kubernetes/pull/76039), [@johnSchnake](https://github.com/johnSchnake))
