The following program behaves differently under Python 3.6:

Selection of button 'A' also selects button 'C'. Same goes for 'B' and
'D'.
I noticed that widget names have changed, which likely leads to the
cause:

.!frame2.!checkbutton
.!frame2.!checkbutton2
Is this a known issue?
I don't believe so; at least, I couldn't see it in the bug tracker.
Me neither. I will open an issue on the tracker.

Presumably you'll want to check the values of the checkboxes, so you'll
bind them to tkinter variables (IntVar, etc). When you do that, it works
correctly.
This still seems like a bug to me. Similar issue
https://bugs.python.org/issue25684 has the same workaround for ttk
Option Menu radiobuttons.
