Projections definitions: Datum of ‘DHDN / 3-degree Gauss’ predefined projection has been set to ‘Potsdam Rauenberg DHDN’. Equirectangular projection (latitude/longitude): Added the standard parallel (where the scale of the projection is true). New projection: ‘Hotine Oblique Mercator’ (old users should change ‘Oblique Mercator’ to ‘Hotine Oblique Mercator’ in their maps). Google Earth: Now are transferred the date-time of track points so track animation is enabled (required Google Earth 5.2 or later). New types of GPS: Brauniger IQ series, DeLorme PN20/30/40, GlobalSat DG-100/BT-335, Holux M-241, MTK Logger, NaviGPS GT-11/BGT-11, SysTraq Venus, Wintec WBT-100/200. The coordinate input box displays now the coordinate in UTM and alternative grid format (if setted in preferences or map). A bug has been fixed when using gpx files containing extensions handled by other software. In this case, some functions, such as saving data gpx and sending data to the GPS, was in error. New feature: okmap.exe can be launched with more than one parameter. Parameters are the files to be opened: map files (.okm) and GPX files (.gpx). Source.
