CityPhi application framework, the CityPhi APIs and example scripts are upgraded to use Python 3. CityPhi is distributed with Python 3.11. The CityPhi Notebook now uses a Python 3 kernel.

User-developed scripts, tools and notebooks may require some changes to work with Python 3. You can find a useful article about Porting Python 2 Code to Python 3 on the Python.org site. Otherwise there are no specific changes to the CityPhi APIs affecting user scripts.
