Ubuntu 17.10 Artful Aardvark released
Pay attention to the 2nd dot point under known issues. This release uses Wayland, and that has profound implications for screenshot, streaming and remote desktop-ing.The Wayland protocol apparently made some bold decisions to enforce security through isolation, and apart from the compositor it is all but impossible for anything to sneak a peak at what other programs are doing visually. It'll be interesting to see if that causes users a problem.
