**Full Changelog**: https://github.com/AnkitBarik/planetMagFields/compare/v1.5.1...v1.5.2

- Fixed bug in potential extrapolation
- Added new test for all three extrapolated components against mattkjames7 's [JupiterMag](https://github.com/mattkjames7/JupiterMag) at twice the planetary radius.

**Full Changelog**: https://github.com/AnkitBarik/planetMagFields/compare/v1.5...v1.5.1

New features:
- Parameters `vmin` and `vmax` for minimum and maximum of color-scale in all plotting functions
- Function `orbit_path` to get field components along a trajectory
- `extrapolate` now provides arrays as objects in `Planet` class
 
Bug fixes:
- `plot_filt` now correctly generates titles

What's Changed
- New auto tests to test parts of the code
- Updated documentation with mathematical details
- Bug fixes
- Updated version of JOSS paper



**Full Changelog**: https://github.com/AnkitBarik/planetMagFields/compare/v1.4...v1.4.3

This release constitutes adding of new features:

- Support for multiple field models for each planet
- Unit testing
- An interactive Jupyter notebook
- Full documentation
- Adding the project to PyPI

Routines to easily access information about magnetic fields of planets in our solar system and visualize them in both 2D and 3D.
Features:

- only numpy, scipy and matplotlib needed to visualize 2D Br plots and Lowes spectra
- internal Hammer projection in the absence of cartopy
- supports all projections from cartopy
- writes vts files for 3D visualization
- potential extrapolation
- spherical harmonic filtering

Bugfixes in this version:

- fixed plot titles.
