---snippet from their update log:

1.4.4 27 July 2016

    Added 5 new algorithms, CRC-8/AUTOSAR, CRC-8/OPENSAFETY, CRC-16/OPENSAFETY-A, CRC-16/OPENSAFETY-B and CRC-32/AUTOSAR from the CRC Catalogue.
    Added a build option to verify the order of the preset and alias tables at compile time.

1.4.3 14 July 2016

    Added algorithm CRC-16/CMS from the CRC Catalogue.

1.4.2 8 July 2016

    Added algorithm CRC-16/PROFIBUS from the CRC Catalogue.

1.4.1a 29 June 2016

    Fixed a regression that caused the Windows release to crash on older systems.

1.4.1 27 June 2016

    -P sets the Width value just like -k.
    pcmp() quickly returns when the comparands are identical.
    Added resources for the Windows executable.
