Version 9.7.0
Release date: Jun 3, 2020
When upgrading RapidMiner Server to version 9.7 or later, you must also update the Python Scripting Extension to version 9.7.
New Features
- As the new repositories support storing arbitrary files, support for dragging and dropping.pyand.ipynbfiles to the canvas has been introduced. RapidMiner Studio will take care of creating the necessary operators.
- Note: no adjustments are made to the code when dragging and dropping, so users still need to take care of creating the rm_main function so the code will get executed properly. A run-time error will be displayed if this is not done.
Enhancements
- Added support for projects, so therapidminerPython library can function correctly.

- Optional hidden parameter (
rapidminer.python_scripting.shell_command) added to avoid potential freeze during extension initialization on Linux and macOS(default value:bash -l -i -c)
