Ops Manager 4.2.2 is now available, building on the stable 4.2 release and adding support for rolling changes of keyfiles, following the August's Ops Manager 4.2.0 release that brought support for MongoDB 4.2 to Ops Manager and merged its three agents into a single agent, replacing Personal API keys with Programmatic API Keys which enable finer grain control of roles and permissions, now available from the download center.
