IPython 2.0 is actually out now! Yay! (https://pypi.python.org/pypi/ipython)
If you don’t believe me then just:

pip install --upgrade ipython

See what’s new at http://ipython.org/ipython-doc/2/whatsnew/version2.0.html

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 IPython notebooks http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/Index.ipynb on nbviewer.

The guys and gals at IPython HQ are asking that we all please give it a test. They plan to have 2.0.1 released within a month – based on the initial feedback.

Bring on the bug reports!
