Why you don't mention anywhere that you stopped supporting Ubuntu 16.04

At one point, your new "wonderful" releases stopped running and not installed on my Ubuntu 16.04. And now your last releases are not installed not from the source, and ready for run also not work from here
https://github.com/216k155/lux/releases/download/v5.0.3/lux-qt-linux.tar.xzThat is, you once switched to new libraries and stopped supporting Ubuntu 16.04

Without warning anyone and not reporting it anywhere, I'm very unhappy with your support, although I've been with you almost since the launch. And what do I do now, install a new version of Ubuntu 18.04, so that everything will work or me sell all my lux? But I can not switch now to Ubuntu 18.04, I have a lot of other settings and programs and it was not in my plans
I just compiled 5.0.3 CLI wallet under Ubuntu 16.04.4 LTS successfully. Did not change any libraries since compiling with 5.0.2 wallet. Wonder is this is a GUI issue?
Devs, Can you officially confirm or deny Ubuntu 16.04 support?
