This makes sense, as Zorin OS 16 Lite appears to use XFCE 4.16, which Xubuntu 20.04 does not do.
(I noticed Tasklist buttons are working properly now, by the way).
It is noteworthy that many distros do not make formal announcements for minor revisions.
However:
A specific release date would be nice, but even a general guess would be, as well.
As a mechanic, I have long noticed that when I am working on a customers car and they are eager for a Finish date and time, my statement of "i am working on it" is often more than enough. They understand that the Universe will repel the best laid of all plans. A specific date and time is nice, but not really what they are looking for. It is the reassurance of "present and accounted for" that they really need.
One thing that is present and accounted for across many different threads, populated by many different people is the need for stronger or more frequent communication from ZorinGroup.
I do not say this as a cold critic. Quite the contrary, I think I have demonstrated for almost Two Full Years now a desire to encourage the Zorin Project.
