The release notes for Red Hat OpenShift for Windows Containers tracks the development of the Windows Machine Config Operator (WMCO), which provides all Windows container workload capabilities in OKD.
Y-stream releases of the WMCO are in step with OKD, with only z-stream releases between OKD releases. The WMCO numbering reflects the associated OKD version in the y-stream position. For example, the current release of WMCO is associated with OKD version 4.16. Thus, the numbering is WMCO 10.16.z.
This release of the Windows Machine Config Operator (WMCO) provides new features and bug fixes for running Windows compute nodes in an OKD cluster. The components of the WMCO 10.16.2 were released in RHSA-2025:9136.
Previously, Windows nodes were unable to pull from image mirror registries if an organization name or namespace was included in the source of the ImageTagMirrorSet
(ITMS) object. With this fix, you can include an organization name or namespace in the ITMS
object. With this change, additional guidelines and requirements around using mirror registries have been added to the OKD documentation. (OCPBUGS-55787)
