Something I forgot to emphasize in the announcement, knowing that not everyone reads the release notes - if you are upgrading from a previous version of IPython, you must either:
- Delete your ~/ipython (or ~/_ipython) directory OR - Run %upgrade once IPython starts. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
