+= Release notes for Red Hat Windows Machine Config Operator 10.21.2
+
+Issued:  August 2026

+The components of the Red Hat Windows Machine Config Operator (WMCO) 10.21.2 were released in https://access.redhat.com/errata/RHBA-2026:TBD[RHBA-2026:TBD].

+== Bug fixes
+
+* Before this update, the SSH connection between the WMCO and a Windows node would terminate when the WMCO rebooted the node after a configuration update. As a consequence, the WMCO incorrectly treated the SSH disconnection as a reboot failure, preventing the Windows node from completing required reboots. With this release, the reboot validation process is modified to ignore SSH termination errors and instead verify a successful reboot by using explicit node reachability checks and the SSH reconnection. As a result, Windows nodes successfully reboot upon node configuration changes. (link:https://issues.redhat.com/browse/OCPBUGS-98229[OCPBUGS-98229])
