There might also be an issue on octave kernel side.
I would also open an issue on octave kernel itself, the author is probably more familiar with it than we are.

IPython 3.0 is still highly in motion, so having different things "almost" working is not too surprising.
Though, the kernel architecture to get basic stuff working is already stable enough that not having any
output is weird.
> As a side-note, I would like to set the figures to svg. With the old system I would write "%%octave -f svg". I cannot figure out how to do that with the new system.
This you would have to see with the octave kernel. -f svg was probably setting an option somewhere.
Good luck !
