4.0.0 - 2024-04-23

Breaking changes:

  • To unify the API, :class:DenseMatrix does not inherit from :class:np.ndarray anymore. To convert a :class:DenseMatrix to a :class:np.ndarray, use :meth:DenseMatrix.unpack.
  • Similarly, :class:SparseMatrix does not inherit from :class:sps.csc_matrix anymore. To convert a :class:SparseMatrix to a :class:sps.csc_matrix, use :meth:SparseMatrix.unpack.

New features:

  • Added column name and term name metadata to :class:MatrixBase objects. These are automatically populated when initializing a :class:MatrixBase from a :class:pandas.DataFrame. In addition, they can be accessed and modified via the :attr:MatrixBase.column_names and :attr:MatrixBase.term_names properties.
  • Added a formula interface for creating tabmat matrices from pandas data frames. See :func:tabmat.from_formula for details.
  • Added support for missing values in :class:CategoricalMatrix by either creating a separate category for them or treating them as all-zero rows.
  • Added support for handling missing categorical values in pandas data frames.

Bug fix:

  • Added cython compiler directive legacy_implicit_noexcept = True to fix performance regression with cython 3.

Other changes:

  • Refactored the pre-commit hooks to use ruff.
  • Refactored :meth:CategoricalMatrix.transpose_matvec to be deterministic when using OpenMP.
  • Adjusted transformation to sparse format in :func:tabmat.from_pandas to future changes in pandas.
