Version 1.1.1.1 (2019-05-02)
- Latest version for Version 1 hardware.
- Corrects improper date that was triggered by the GPS 1024-week rollover on April 7, 2019.
- Updates World Magnetic Model used for magnetic variation calculation from WMM2015 to WMM2015v2.

Version 1.1.0.1, 3.7.1.1, 4.0.1.1: (2015-03)
- Added support for new World Magnetic Model WMM2015 to make magnetic variation calculation as accurate as possible (3398)

Version 4.0.0.4 (2014-03-04)
- Latest version for Version 3 hardware.
- Adds support for Version 3 hardware.

Version 3.5 (2011-12-01)
- Latest version for Version 2 hardware.
- Adds support for Version 2 hardware.

Version 2.2 (2011-02-10)
- Updated the magnetic variation function to use the new WMM2010 coefficients. This corrects a problem where magnetic variation is not available, which causes true heading readings to be unavailable or missing.

Version 1.0.7 (2011-06-17)
- Latest firmware version for Version 1 hardware
- Corrected PGN properties
- Updated supported NMEA 2000 database version to 1.300

Version 1.0.6 (2010-02-11)
- Updated the magnetic variation function to use the new WMM2010 coefficients. This corrects a problem where magnetic variation is not available, which causes true heading readings to be unavailable or missing
- Corrected a problem where the GPS would not achieve a position fix when first powered up a very small percentage of the time .
- Corrected a problem where the value transmitted for speed over ground was sometimes incorrectly scaled, resulting in a value in excess of the actual speed over ground.

Version 1.0.4 (2009-02-11)
- Corrected a problem where the position would drop out after an extended period of operation (usually a minimum of 12 hours)
