Hardware: Unspecified   
OS: Unspecified   
Fixed In Version: Doc Type: Bug Fix
Doc Text:
In this release, the NET_RAW and SYS_CHROOT capabilities are no longer available in the default list of CRI-O capabilities. To reduce impact to clusters created in releases before <4.5.z>, the default capabilities list is now contained in separate machine configs: 99-worker-generated-crio-capabilities and 99-master-generated-crio-capabilities. The cluster creates the new machine configs when you upgrade from a previous release. After upgrading, you should disable the NET_RAW and SYS_CHROOT capabilities, and then test your workloads. When you are ready to remove these capabilities, delete the 99-worker-generated-crio-capabilities and 99-master-generated-crio-capabilities machine configs. If you are upgrading from an earlier release, you must upgrade to <4.5.z> before you upgrade to this release.

Comment 24 W. Trevor King 2020-10-16 18:01:18 UTC
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 ;).
