I don't have a strong reason, but I have been seeing a lot of Remoting-related issues on 2.60.3 LTS. I rely heavily on the SSH Slaves and Swarm Plugins. I haven't had time to systematically debug them, but I saw that there has been a lot of activity fixing Remoting bugs (especially
JENKINS-45294 and JENKINS-45023). So I want to try and upgrade to 2.73.x first and see if the issues are resolved before investigating further. Therefore it would be nice to see this in the next 2.73.x LTS release. No problem if it's too difficult, though.
