#115 please add support to ipython 4.x series

[Frédéric PICCA]

Hello,

In order to prepare the next Debian stable release, it would be great to add the ipyton 4.x series support to pytango in the 8.x series and maybe the 9.x series if possible.

tango9 is not yet part of Debian so it would be nice to support the current 8.x series.

thanks

Frederic
