Thanks! Since many users are struggling with IPython versions and the notebook, we need a fallback on IPython.nbformat if they have not successfully upgraded to nbformat, so I did a nested try for those imports. Also upgraded this import in ipynb.py for writing notebooks.
There are several small enhancements:
"".join
instead ofdostr+=...
as it is more effective (see Shlemiel the painter's algorithm for details)
