• Add support for Python 3.12.
• Drop support for Python 3.8.

• Raise an error if a single coder is provided (or if all units were assigned less than 2 coders).
• Raise an error if the output dtype is not np.inexact.
• Change asserts to ValueErrors
• Define more specific typing for the level of measurement, the distance metric callable, the NumPy arrays, and dtypes.

• Add support for Python 3.11.
• Remove support for Python 3.7.

• Fix an issue that breaks the usage of missing values (NaNs) when using a string dtype (thanks @normangilmore for the fix!).

• Add support to Python 3.10 and drop support to Python 3.6.
• Allow specifying the return dtype as a parameter in the function alpha.

The distance metric functions now take NumPy arrays as input and output. The input arrays are broadcasted to determine the shape of the output.

• Add support for Python 3.9.
• Remove support for Python 3.5.
• Add typing annotations.

• Remove pypandoc setup dependency.
• Add missing numpy install dependency.

Remove support to Python 3.4 and declare explicit support to Python 3.8.

• Fix 'ordinal' metric, which was giving a slightly different value for alpha.
• Remove support to Python 3.3.
