ipython 7.x and ipykernel 5.x

[Steve Wills]

Hi,

Trying to update devel/py-jupyter_console and devel/py-qtconsole, I 
found that I need ipython 7.x and ipykernel 5.x. I already created 
devel/py-prompt_toolkit2 since prompt_toolkit 2.x is incompatible with 1.x.

Should I commit separate ports for devel/ipython7 and 
devel/py-ipykernel5 or do you have plans to update devel/ipython and 
devel/py-ipykernel? Note I already have devel/ipython7 and 
devel/py-ipykernel5 tested and working locally. But I thought we may 
prefer to just update rather than keep so many versions around. What's 
your preference?

Thanks,
Steve
