- kubelet: on Windows, consistently resolve filesystem links to volume identifiers instead of inconsistently normalizing to drive letters.

* 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...

    *   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)]

- disableAvailabilitySetNodes is added to avoid VM list for VMSS clusters. It should only be used when vmType is "vmss" and all the nodes (including masters) are VMSS virtual machines. ([#87685](https://github.com/kubernetes/kubernetes/pull/87685), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

* fixed foreground deletion of podtemplates ([#60683](https://github.com/kubernetes/kubernetes/pull/60683), [@nilebox](https://github.com/nilebox))

* Conformance tests are added for the DaemonSet kinds in the apps/v1 group version. Deprecated versions of DaemonSet will not be tested for conformance, and conformance is only applicable to release 1.10 and later.

#### Container Runtime Interface

* **the `gce` provider ensures the bootstrap admin token user is included in the super-user group ([#39537](https://github.com/kubernetes/kubernetes/pull/39537), [@liggitt](https://github.com/liggitt))**
* Remove support for debian masters in GCE kube-up. ([#41666](https://github.com/kubernetes/kubernetes/pull/41666), [@mikedanese](https://github.com/mikedanese))

### SIG Scalability

SIG Scalability has mostly focused on stability and deflaking our tests, investing into framework for writing scalability tests (ClusterLoader v2) with a goal to migrate all tests to it by the end of 2018 and on the work towards extending definition of Kubernetes scalability by providing more/better user-friendly SLIs/SLOs.
