I've read over the information I can find on 17.04 Zesty Zapus
https://wiki.ubuntu.com/ZestyZapus/ReleaseNotes
The only information I can go off of for official support:
"Ubuntu 17.04 will be supported for 9 months until January 2018. If you need Long Term Support, it is recommended you use Ubuntu 16.04 LTS instead."
Does this indicate that 17.x will not at any point have long term support?
Edit: This was specifically related to if 17.04 Zesty Zapus was going to be receiving LTS. Not about defining the difference between Non-LTS and LTS. This is meant to be informational to this specifically, not a duplicate of a more broad question.
