Hello,
We have upgraded our Jenkins installation to version 1.480.2 (LTS release). My basic regression tests did not catch any issue, if you see anything wrong please ping me and or open a bug report against "Wikimedia > Testing Infrastructure" in Bugzilla (I am in CC).
The bug requesting the upgrade was: https://bugzilla.wikimedia.org/show_bug.cgi?id=41973
I will get the Jenkins plugin updated this afternoon.
cheers,
