At long last, a new release! Certainly deserving of a major point release, this release brings many important changes and fixes including: Quality of life Forward compatibility with modern Python 3.x branches Drops compatibility with Python 2.x Move to pytest for CI as nose is no longer maintained Documentation and CI moved to GH-actions rather than Travis tox.ini to facilitate local testing in a virtual environment using tox The lenient parameter is now True by default for system simulations Update documentation infrastructure to Sphinx 8.x compliance Fixed Scipy compatibility with pinv2 removed in favor of pinv setup.cfg removed in favor of pyproject.toml Fixes Fixes to documentation (examples as well as docstrings) Style improvements throughout the package Fixed a subtle error in piecemf, and added new inverse ipiecemf function Fixed a bug which resulted in the cmeans maxiter stopping one short of the desired number of loops Fixed a bug in universe resampling which affected legacy fuzzy_and and fuzzy_or-like operations. This did not affect the skfuzzy.control API.
