How to upgrade or install Ipython for python 3.x support?

Hi,

I mostly use ipython as SymPy interface that serves as CAS (Computer 
Algebra System) application in Devuan (Debian without systemd) Linux.

The ipython supports python 2.x I believe.

$ ipython --pylab
Python 2.7.10+ (default, Oct 10 2015, 09:11:24)
Type "copyright", "credits" or "license" for more information.

IPython 2.3.0 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.
Using matplotlib backend: TkAgg

I'm planning to replace all previous python codes I've written to Python 
3.x. Is there Ipython version that supports Python 3.x?

Regards,
Hughe
