Comment 6 for bug 1647467

Feel free to take your time on zesty if you want to get it in via e.g. 1.4~beta3 or 1.4.1 or whatever. It's nice to get fixes into devel quickly for those who run it but we don't promise security support for it the same way we do the released releases.

Also note that vivid and wily are EOL. Even though vivid's zombie lives on in Ubuntu touch and snappy core I think the headline feature of those platforms is image-based updates, not apt-based updates, so I suspect we can ignore even vivid.

Thanks
