## Dependencies

### Added
_Nothing has changed._

### Changed

  - build: Use go-runner:buster-v2.0.1 (built using go1.15.1)
  - bazel: Replace --features with Starlark build settings flag
  - hack/lib/util.sh: some bash cleanups
    
    - switched one spot to use kube::logging

      found errors".

	// first, if it is available, then fall back on the default
	// (as determined by kubelet) DNS settings.
	DNSClusterFirstWithHostNet DNSPolicy = "ClusterFirstWithHostNet"

	// DNSClusterFirst indicates that the pod should use cluster DNS
	// first unless hostNetwork is true, if it is available, then
	// fall back on the default (as determined by kubelet) DNS settings.
