IPython 4.0 is out, or in other words, everything is now “Jupyter.” The devs wrote a blog post on it:

[http://blog.jupyter.org/2015/08/12/first-release-of-jupyter/](http://blog.jupyter.org/2015/08/12/first-release-of-jupyter/)

Main points

- It’s now `jupyter notebook`
- Configs are now in `~/.jupyter`
- The Jupyter transition split the ipython package into sub packages that can be installed independently. `pip install jupyter` installs a metapackage that installs all the Jupyter packages.
- `pip install ipython` only gets you the command line terminal binary.
