This is the last release of iPython which will be called Jupyter Julia, Python and R name mash up) to show the kernel agnostic nature of the product. iPython will only refer to the Python specific parts AKA the interactive python kernel and a few other pieces. You can run iPython/Jupyter with over 30 different kernels. My favorite is R and Haskell. https://github.com/ipython/ipython/wiki/IPython%20kernels%20...
Just a note in passing as many people make the mistake when writing about IPython: the name of the project is written 'IPython' instead of 'iPython'. The project maintainers would like to encourage people to avoid the latter casing, in particular to avoid any confusion with Apple products. If you don't like the 'IPython' casing it's better to just use lowercase 'ipython' instead.
I am the last person in the world that would ever want to have anything Apple seen in other projects. I will always go with IPython, BUT once again Apple steals something that wasn't theirs iX was before iMac.
