**Full Changelog**: [https://github.com/FraunhoferIWES/foxes/commits/v0.3.2](https://github.com/FraunhoferIWES/foxes/commits/v0.3.2)

- Input states:
- Improved: `FieldDataNC` now supports states subset selection
- Wake frames:
- Improved: `Streamlines` now with maximal length option
- Turbine models:
- New: `Calculator`, simple variable calculation via user function
