[IPython-dev] IPython 7.0.0b1 released on PyPI. Thanks Paul !

[Aaron Meurer]

I would suggest producing a better error message if IPython 7 is run
with prompt-toolkit 1. Right now, it gives `ImportError: No module
named 'prompt_toolkit.formatted_text'`

Also, the SymPy tests all still pass with IPython 7, so everything is
good there.
