v1.6.0

• Requirements

  • Increased minimum version of SeeK-path to 2.2.1

    • Recent updates provide improved compatibility with recent spglib versions
      and allow q-point paths to be generated in the input cell orientation.

  • Security

    • Bumped wheel requirement for docs and testing to 0.46.2. (CVE-2026-24049 <https://www.cve.org/CVERecord?id=CVE-2026-24049>_)

• Bug fixes

  • Band structures paths could be generated with incorrect
    correspondence of q-points to symmetry labels if the input cell
    was transformation of reference primitive cell. (e.g. different
    order of lattive vectors). This is now fixed by using features of
    SeeK-path 2.1+.

  • Band structure paths would be inappropriately generated and
    labelled if the input cell was a supercell of the primitive cell.
    This scenario now emits a warning (from Seek-path) and the tick
    labels will not use the traditional high-symmetry labels.

• Improvements

  • Extended pathlib.Path support and annotations throughout the code. Removing
    references to os.path where no longer relevant.

  • Rework Spectrum*.copy() to meet Python copy <https://docs.python.org/3/library/copy.html>__ specifications.

• Maintenance

  • Replace tmpdir in tests with tmp_path and use Path handling.
