Changes in version 0.2.3 (2026-03-13)                  

  - Improvements: Zero fat mass in dataset no longer throws an error;
    throws a warning instead and assigns flight range of zero.

      - Garden Warblers (garden_wablers) and Lesser Whitethroat
        (lesser_whitethroats) collected along the southern migration
        routes in autumn.
      - Curlew Sandpiper (curlew_sandpiper) studied and measured under
        lab conditions.

  - Documentation: Analysis of the above datasets are included in the
    README file.
