fetch, submit, collect)
- Add a new assignment list extension which allows students to list,
fetch, validate, and submit assignments from the notebook dashboard
interface
- Auto-resize text boxes when giving feedback in the formgrader

I\'m happy to announce that the first version of nbgrader has (finally)
been released! nbgrader is a tool that I\'ve been working on for a
little over a year now which provides a suite of tools for creating,
releasing, and grading assignments in the Jupyter notebook. So far,
nbgrader has been used to grade assignments for the class I ran in the
spring, as well as two classes that Brian Granger has taught.

If you have any questions, comments, suggestions, etc., please do open
an issue on the bugtracker. This is still a very new tool, so I am sure
there is a lot that can be improved upon!
