                 Changes in version 0.2.0 (2026-05-02)                  

new features

  - New format_nucl() formats chemical isotopes in nuclear notation.
  - formatdown_options() gains the Z and warn arguments used by
    format_nucl().

minor improvements and fixes

  - format_numbers(0, format = "sci") now correctly yields a zero
    without power-of-ten notation. Likewise for format = "engr" (#10).
  - In formatdown_options(), multiply_mark can now be set to "\\cdot"
    (center dot), often used when decimal_mark is a comma.
