https://openshift-release.apps.ci.l2s4.p1.openshiftapps.com/releasestream/4.5.0-0.nightly/release/4.5.0-0.nightly-2020-10-16-165114 brings in the new MCD RPM with a machine-os-content RHCOS bump to 45.82.202010161329-0. I'm a bit fuzzy on whether it's the RPM or a container image that's used for in-cluster MCDs, but probably worth using 4.5.0-0.nightly-2020-10-16-165114 or later for verification just in case ;).
