## Version 6.4.2 -- 19 September 2011

- elevation graphs for tracks using `gnuplot`; implemented by plug-ins contributed by Rudolf Martin (rudolf.martin`_at_`gmx.de).

- for tracks, improved computation of total (or cumulative) ascent/descent, computation of rest periods, total resting time and average speed in motion, estimated time for a hiking trail; contributed by Rudolf Martin.

- new configuration parameter: user temporary files directory; must be set correctly for GPSMan to work; it defaults to `.tmp` under the user GPSMan directory.

- new user options: altitude threshold when computing cumulative ascent/descent, operating system commands to display an image file and open a terminal (command-line) window; default of altitude threshold is appropriate for GPS receivers with non-barometric altimeter.

- change in default for user option (was a configuration parameter): the print command starts now by being empty (meaning unavailable).

- new projections: Mercator spherical case, Equidistant Cylindrical, and their particular cases EPSG:3857 (also known as EPSG:900913, EPSG:102113) and EPSG:32663 (Plate Carree with WGS 84 datum); asked by Rudolf Martin.

- in order to avoid ill formed or inconsistent data files, appending to a file is no longer an option when writing to an existing file except in the case of results of computations, real-time logs and contents of information windows.

- windows presenting results that depend on the definition of a route or track, such as computations or graphs, may be closed when the item changes after being edited or being replaced when data is read-in; based on a change suggested by Rudolf Martin.

- unavailable expression of plug-ins are now evaluated at top level so that global variables can be used.

- explicit support for the Garmin GPS 72H receiver; with thanks to Justin Arundell and Julian Barragan who sent protocol lists.
