Changes

0.4.1 (2024-06-03)

  • Introduce pyproject.toml to replace the old way of describing the project and specifying build dependencies, thanks to @filip-komarzyniec (see PR #31).

0.4.0 (2023-11-30)

  • Add support for Python 3.12.
  • Don't track the C file generated by Cython anymore.

0.3.3 (2023-07-03)

  • Fix error when JenksNaturalBreaks is instanced with n_classes=1 and raise error if n_classes is not a positive integer (fix #28).

0.3.2 (2022-11-10)

  • Add type hints and fix some docstring about parameters and return types, thanks to Kim Hyeonseok / @plming (#27).

0.3.1 (2022-08-23)

  • Add missing requirements.txt file in MANIFEST.in and in sdist package.

0.3.0 (2022-08-23)

  • Add NumPy as a mandatory dependency.
  • Only compute matrices in C code and move sorting the values, casting to double, and computing the actual breaks to Python/Cython code for better maintainability.
  • Improve performance by using 1D arrays instead of 2D arrays in JenksBreakValues C function.
  • Preserve the precision of the original list/array of values in the returned breaks.
  • Fix bug when requesting a number of class equal to the number of values.
  • Raise an exception when the number of classes is greater than the number of unique values (however this might change in the future by choosing to return a list of breaks shorter than the one requested by the user).
  • Rename nb_class parameter to n_classes (notably to be closer to sklearn n_clusters parameter).

0.2.4 (2022-08-18)

  • Update package metadata and docstrings.

0.2.3 (2022-08-18)

  • Check size of integer values given to jenks_breaks function to avoid Segfault when casting to C double (fixes #23).
  • Raise an error (instead of printing a warning) when target array contains non-finite values (fixes #23).
  • Raise an error when the target numpy.ndarray is not one-dimensional (fixes #25).
  • Improve implementation of JenksBreakValues C function by using better variable naming and by simplifying the construction of the 'breaks' array (should partly fix #22).
  • Add docstrings to JenksNaturalBreaks methods.

0.2.2 (2022-08-12)

  • Update docstring to fix return type of jenks_breaks (fix #26).

0.2.1 (2022-08-12)

  • Add a method to the JenksNaturalBreaks class that calculates the Goodness of Fit Variance thanks to Maurício Gomes / @mgomesq (#17).
  • Add optional download numpy using [interface] thanks to Muhammad Yasirroni / @yasirroni (#16).
  • Replace Travis / AppVeyor by GitHub Actions to build wheels for currently supported python versions on Windows / MacOs / Linux (according to https://devguide.python.org/versions/#supported-versions)

0.2.0 (2020-10-18)

  • Add JenksNaturalBreaks for computing breaks in a more object-oriented manner, with an interface similar to those provided by scikit-learn (requires Numpy to take full advantage of it) (thanks to @yasirroni, #11)

0.1.6 (2020-09-02)

  • Removes support for Python2 (simplifies some minor parts of the code) and add Python 3.8 to the appveyor matrix.
  • Updates docstrings and README to clarify that the result includes the lower and upper value.

0.1.5 (2018-11-15)

  • Fix segfault occurring when the input array was containing NaN or Inf values (#4).
  • Create this changelog.
