> Upgrade to Jenkins v1.613 is now complete and Jenkins seems to be largely doing fine. Several plugins of Jenkins have also been updated to their latest versions. During the course of the upgrade, I noticed that we were using the deprecated 'gerrit approve' interface to intimate status of a smoke run. Have changed that to use 'gerrit review' and this seems to have addressed the problem of smoke tests not reporting status back to gerrit.
