Beginning with Jenkins 2.407, May 30, 2023, Jenkins administrators running a Jenkins weekly release will be warned if they are running Jenkins on an operating system that is within 6 months of its end of life date. The same warning will be visible to Jenkins administrators running a Jenkins long term support (LTS) release with the next LTS baseline after Jenkins 2.401.x, beginning August 23, 2023.
But we’re all keeping well ahead of the EOL dates on our OS’s, right? :P
