[IPython-dev] Upgrading Kernels for IPython 3

[Andrew Gibiansky]

Kiko,

Just to clarify, I need a command that *does* work on IPython 3. I can
already do this for IPython 2, and am looking for the equivalent once 3 is
released. In both the links you provided, it says that in IPython 3 you
have to select it from a dropdown, which does not work for me.
