Bug fix:

- Package ``requirements.txt`` and update the dependencies list: remove
``scipy`` and add ``scikit-learn``. Exclude ``license_notice.py`` and
``.flake8`` from the ``MANIFEST.in`` (`261 <https://github.com/fatiando/harmonica/pull/261>`__)

Deprecations:

- Rename equivalent sources classes to ``EquivalentSources`` and ``EquivalentSourcesSph``. The old ``EQLHarmonic`` and ``EQLHarmonicSpherical`` will be removed on v0.5 (`255 <https://github.com/fatiando/harmonica/pull/255>`__)
- Rename the ``relative_depth`` parameters in ``EquivalentSources`` to ``depth``. The old ``relative_depth`` parameter will be deleted on v0.5 (`236 <https://github.com/fatiando/harmonica/pull/236>`__)

New features:

- Enable parallelization on tesseroids forward modelling and refactor its code (`244 <https://github.com/fatiando/harmonica/pull/244>`__)
- Add option to set ``EquivalentSources`` points to constant depth (`236 <https://github.com/fatiando/harmonica/pull/236>`__)
- Allow ``prism_layer`` to take Xarray objects as arguments (`243 <https://github.com/fatiando/harmonica/pull/243>`__)

Maintenance:

- Generate version string on ``_version.py`` on build (`237 <https://github.com/fatiando/harmonica/pull/237>`__)
- Run CIs only on the two ends of supported Python versions (`256 <https://github.com/fatiando/harmonica/pull/256>`__)
- Transform ``require_numba`` decorator into a global variable (`245 <https://github.com/fatiando/harmonica/pull/245>`__)

Documentation:

- Fix typo: replace bellow for below across docstrings (`253 <https://github.com/fatiando/harmonica/pull/253>`__)
- Fix version display in the HTML title (`249 <https://github.com/fatiando/harmonica/pull/249>`__)

- Change order of dims in example of ``prism_layer`` (`241 <https://github.com/fatiando/harmonica/pull/241>`__)
- Fix class name on See also section in ``prism_layer`` (`230 <https://github.com/fatiando/harmonica/pull/230>`__)
- Use the Jupyter book Sphinx theme instead of RTD (`227 <https://github.com/fatiando/harmonica/pull/227>`__)

- Parallelize EQLs predictions and Jacobian build (`203 <https://github.com/fatiando/harmonica/pull/203>`__)
- Improve EQL harmonic classes by splitting classes and adding upward argument to prediction methods (`190 <https://github.com/fatiando/harmonica/pull/190>`__)
- Add function to compute the distance between points given in geodetic coordinates (`172 <https://github.com/fatiando/harmonica/pull/172>`__)
- Allow ``load_icgem_gdf`` to take open file objects (`155 <https://github.com/fatiando/harmonica/pull/155>`__)
- Add new ``EQLHarmonicSpherical`` class to interpolate data using EQL in spherical coordinates (`136 <https://github.com/fatiando/harmonica/pull/136>`__)
