[IPython-user] IPython.kernel.client.Task is not present!

[Brian Granger]

Mark,

I am in the process of finishing updating the docs.  When they are
done, I will let you know.  I would love to get feedback from you on
this.  I am hopeful that the new docs will answer all of your
questions.

Cheers,

Brian
