### Bug or Regression

* Use separate client for leader election in scheduler to avoid starving leader election by regular scheduler operations. ([#53793](https://github.com/kubernetes/kubernetes/pull/53793), [@wojtek-t](https://github.com/wojtek-t))

    * 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))

  
  - make kube::util::find-binary not dependent on bazel-out/ structure
  
    Implement an aspect that outputs go_build_mode metadata for go binaries,
    and use that during binary selection. ([#94449](https://github.com/kubernetes/kubernetes/pull/94449), [@justaugustus](https://github.com/justaugustus)) [SIG Architecture, CLI, Cluster Lifecycle, Node, Release and Testing]
- Kubernetes is now built using go1.15.5

- Updated the comment about the feature-gate level for `PodFailurePolicy` from alpha to beta ([#118278](https://github.com/kubernetes/kubernetes/pull/118278), [@mimowo](https://github.com/mimowo))
- `client-go`: Improved memory use of reflector caches when watching large numbers
  of objects which do not change frequently. ([#113362](https://github.com/kubernetes/kubernetes/pull/113362), [@sxllwx](https://github.com/sxllwx))

### Other (Cleanup or Flake)

- Client-go: reduce verbosity of "Starting/Stopping reflector" messages to 3 again ([#102788](https://github.com/kubernetes/kubernetes/pull/102788), [@pohly](https://github.com/pohly)) [SIG API Machinery]
- Update the Debian images to pick up CVE fixes in the base images:

* 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))

- Updated the default API priority-and-fairness config to avoid endpoint/configmaps operations from controller-manager to all match leader-election priority level. ([#106725](https://github.com/kubernetes/kubernetes/pull/106725), [@wojtek-t](https://github.com/wojtek-t))

* Paginate requests from the kube-apiserver watch cache to etcd in chunks. ([#75389](https://github.com/kubernetes/kubernetes/pull/75389), [@jpbetz](https://github.com/jpbetz))
    * Paginate reflector init and resync List calls that are not served by watch cache.
