v0.2.1 (March 2026)

Bug fixes

• Fix off-by-one in :py:func:antropy.higuchi_fd: the inner loop summed :math:N_m - 1 differences per sub-series instead of the correct :math:N_m, causing a systematic underestimate of curve length. Verified against the NeuroKit2 reference implementation.
• :py:func:antropy.sample_entropy now returns np.nan (instead of 0) when no template of length m matches within the tolerance, since the entropy is mathematically undefined in that case.
• Fix silent epsilon = 10e-9 (= 1e-8) typo in utils.py; corrected to 1e-9. This constant guards against division-by-zero in the Numba linear regression used by :py:func:antropy.detrended_fluctuation.
• Fix all = [...] → __all__ = [...] in all three source modules, which previously leaked imported names (np, jit, KDTree, …) into the public namespace on from antropy import *.

New features

• :py:func:antropy.hjorth_params gains an optional sf parameter. When provided, mobility is returned in Hz instead of samples⁻¹ (multiplied by sf); complexity is unaffected.

Validation

• User-facing assert statements replaced with proper ValueError / TypeError raises throughout (asserts are silently stripped by python -O): perm_entropy(delay=0), spectral_entropy(method=…), app_entropy/sample_entropy(tolerance=…), and lziv_complexity(sequence=…, normalize=…).

Docs

• Docstring formula for :py:func:antropy.higuchi_fd corrected to match the fix above (:math:\sum_{j=1}^{N_m} not :math:\sum_{j=1}^{N_m-1}).
• Added notes to :py:func:antropy.lziv_complexity (float arrays are truncated to uint32, not discretised — binarise continuous signals first), :py:func:antropy.num_zerocross (signbit(0) == False behaviour), :py:func:antropy.spectral_entropy (DC component included), :py:func:antropy.detrended_fluctuation (:math:\alpha \approx 1 is ambiguous), and :py:func:antropy.hjorth_params (mobility units).

v0.2.0 (March 2026)

Build & CI

• Drop Python 3.9 (EOL), add Python 3.13 support. Minimum is now Python 3.10.
