(Bringing back to yt-dev) I think we should come up with a timescale for upgrading the dependency stack. I'd like to propose that we upgrade the script for the 3.0 release to include IPython 2.0.0, and that the widgets Ben, Nathan and Sam have been working on make their way in to the repo. -Matt On Wed, Apr 2, 2014 at 2:05 AM, Nathan Goldbaum <nathan12343@gmail.com> wrote:

While April 1 may be a very loose definition of winter, IPython 2.0 is actually [out](https://pypi.python.org/pypi/ipython)!

I promise this is not an April Fool's joke, but if you don't believe me just

pip install --upgrade ipython

to find out.

See [what's new](http://ipython.org/ipython-doc/2/whatsnew/version2.0.html) for more details, but the highlights are:

- interactive widgets for the notebook - directory navigation in the notebook dashboard - persistent URLs for notebooks - a new modal user interface in the notebook - a security model for notebooks

You can check out the [example notebooks](http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/Inde...) on nbviewer, or download them and try things out yourself.

This is the first IPython release with wheels (one for py2, one for py3, for now), so please give those a test if you can. These will be installed by default for anyone using current pip (1.5).

We plan to have 2.0.1 within a month based on initial feedback, so bring on the bug reports!

Thanks for all your support, we have a great time working on this.
