v0.4.0

Released on: 2022/08/09

doi: https://doi.org/10.5281/zenodo.6779998

WARNING: Boule v0.4.0 is the last release that is compatible with Python 3.6.

Backwards incompatible changes:

• Refactor the Sphere class to not inherit from Ellipsoid. Breaks backwards compatibility due to the removal of inherited methods and attributes (#129)
• Make all package modules private by adding a leading _ to their name (#119)
• Rename the Ellipsoid.emm attribute to Ellipsoid._emm to make it private (#123)
• Remove the boule.test function (#116)

Deprecations:

• Deprecate the coordinate conversion methods which have been ported to the pymap3d library v2.9.0 (#126)

New features:

• Add the volume property to Ellipsoid (#132)
• Add missing attributes to Ellipsoid for pymap3 compatibility (#121)
• Add the TriaxialEllipsoid class with geometric parameters (#72)
• Add a normal gravitation method to Sphere (#73)

Documentation:

• Add a logo for Boule (#125)
• Refactor the documentation tutorials to shift the focus to how to do things with Boule and point to other pages for more of the theory (#130)
• Refactor documentation of TriaxialEllipsoid (#128)
• Refactor the documentation of Ellipsoid (#127)
• Fix formatting for code to pip install from GitHub (#118)
• Fix license link and compatibility warning in the README (#117)
• Use jupyter-sphinx instead of sphinx-gallery and update the documentation front page (#112)
• Point to our organization wide guides in the documentation (#108)
• Add an example calculating global gravity disturbances (#102)
• Update Sphinx version to 4.5.0 (#103)

Maintenance:

• Convert the README to Markdown (#113)
• Specify oldest supported version of each dependency (#111)
• Move to pyproject.toml/setup.cfg with build instead of setup.py (#110)
• Replace pylint with flake8 and some extensions (#109)
• Rename the git "master" branch to "main" (#107)
• Update code style to Black 22.3.0 (#104)
• Replace Google Analytics with Plausible for page visit statistics (#99)

v0.1.1

This release contains only a documentation fix: include install instructions for conda and pip. No functionality has been changed (hence, no DOI was issued).

v0.1.0

DOI: 10.5281/zenodo.3603997

First release of Boule including basic functionality:

• Definition of the Ellipsoid class: based on the semi-major axis, flattening, geocentric gravitational constant, and angular velocity. Other quantities are derived from these 4.
• Computation of normal gravity and coordinate conversions between geodetic and geocentric.
• Ellipsoid realizations for the Earth (WGS84 and GRS80) and Mars.
