Action items

• CI Signal reported that k8s.io/kubernetes/test/integration/job.TestMain is failing and it has been labeled release-blocker. The release was delayed until the fix ( job controller: don't mutate shared cache object kubernetes#100553 ) merged.
• We hit a bug in the GCB job composing code where it would fail when trying to get the kubecross version for a release branch that does not yet exist. Fixed in GCB: Fall back to latest v of KubeCross when release branch does not exist release#1974
• A bug in the root Kubernetes Makefile was causing the conformance images not to be built. Fixed in Add KUBE_BUILD_CONFORMANCE on package-tarballs target kubernetes#100571
• Found a bug where the commit in the marker at is not the latest and leaves out 3-4 commits: Building at version marker commit leaves out latest changes  release#1976
• The release process got rate limited when pulling from Docker Hub. To solve it we implemented a new feature to have krel login with a new release engineering docker account Log in to DockerHub during staging before starting build release#1979
