Changelog

Version 0.4.0

Released on: 2021/12/02

Digital Object Identifier for the Zenodo archive

New features:

  • Allow EquivalentSources to define block-averaged sources through a new block_size argument [Soler2021]. (#260)

  • Add dtype argument to EquivalentSources. Allows to select the data type used to allocate the Jacobian matrix. (#278)

  • Add a new EquivalentSourcesGB class that implements gradient-boosted equivalent sources. Provides a method to estimate the amount of computer memory needed to allocate the largest Jacobian matrix [Soler2021]. (#275)

  • Allow tesseroid_gravity to compute gravitational fields of variable density tesseroids. Implements the density-based discretization algorithm and takes numba.njit decorated density functions as input [Soler2019]. (#269)

Breaking changes:

  • Rename point_mass_gravity to point_gravity. Having mass and gravity in the same function name is redundant. The function name has the same structure as other forward modelling functions (tesseroid_gravity and prism_gravity). The old point_mass_gravity will be deprecated on the next release. (#280)

Bug fixes:

  • Fix bug with the require_numba pytest mark and rename it to run_only_with_numba for improved readability. (#273)

Documentation:

  • Fix typo on EquivalentSources docstring: replace bloc_size with block_size. (#276)

  • Minor improvements to the docs: fix bad references and links, replace Equivalent Layer for Equivalent Sources on API Index, fix bad RST syntax. (#274)

Maintenance:

  • Rename the default branch: from master to main (#287)

  • Replace pylint for flake8 extensions. Add isort for autoformatting imports. (#285)

  • Replace conda for pip on GitHub Actions and split requirements files for each separate task. (#282)

  • Make GitHub Actions to check if license notice is present in source files. (#277)

  • Remove configuration files for unused CI: Stickler, Codacy and CodeClimate (#197)

  • Replace TravisCI and Azure for GitHub Actions (#189)
