Python node inside CN fails when opening a 0.83 file in 0.82

This is extremely frustrating. Any idea why it is happening?

This is a clear regression. I'm going to guess this has to do with @pbidenko's recent cleanup of the python code. We'll take a look at this ASAP.

This happens because the Python node is "from the future." The name of the underlying Python node changed in 0.8.3 from DSIronPythonNode.PythonNode to PythonNodeModels.PythonNode. If you'd like, you can open up your dyn/dyf file in a text editor (e.g. notepad++) and change this appropriately and it will open fine in 0.8.2. Your file should still open fine in 0.8.3.
