   In HDDS-3978, to show more information on Recon, a few “static” fields like version and setup time were added to the core DatanodeDetails proto that is used for every heartbeat. In a subsequent JIRA (HDDS-4039), these fields are being moved to DN Register proto instead of heartbeat proto. If the changes in HDDS-3978 are shipped with 0.6.0 (GA), we could never remove them due to backward compatibility. If we revert HDDS-3978 instead, then the subsequent JIRA does not need to worry about backward compatibility. cc @runitao .
