Hi,

IMHO, it would be better to keep 2 versions, one for python 2 and one
(latest) for python 3, at least before we change default python to 3.x.
That is to update ipython to 7.x and devel/py-ipykernel to 5.x. It means we
also have to keep 2 versions for the dependent ports,
e.g. devel/py-jupyter_console5 for 5.x and devel/py-jupyter_console for 6.x.

BTW, regarding py-prompt_toolkit, I've planned to update
devel/py-prompt_toolkit to 2.x and keep the 1.x as devel/py-prompt_toolkit1
because some of the dependent ports migrate from prompt_toolkit 1.x to 2.x
and others are not yet. I prefer to keep the latest version in the ports
tree without suffix.
