Sorry @qiujian16 we might have to do another patch release to bring the old application-manager add-on back. Please let me know if you want me to try to do a release.

@mikeshng you will need to update the version.go and tag the new release after.

@qiujian16 I am not moving up the OCM version tho. I am just bringing the old application-manager addon back. I don't think I need to make the changes in https://github.com/open-cluster-management-io/clusteradm/pull/491/files Please confirm. Thanks!

Also, can I do a pre-release first so @nirs and his team can test it out before the actual release?
