## Version 5.3

- real-time logging and a moving map; the details depend on which communication protocol is used, as described above.
- coordinates for the following national grids: British (BNG), Portuguese (CMP), German (GKK), Irish (ITM), Finnish (both KKJP and KKJY), and Swedish (SEG); permission to translate code in GPStrans was granted by Janne Sinkkonen (janne`_at_`iki.fi) for KKJY and by Anders Lennartsson (anders.lennartsson`_at_`sto.foa.se) for SEG.
- several more datums; the current number is now 144.
- balloon help in limited use: for showing the track name and number of each track point in the map, in answer to a different suggestion from Urs Forster (forster`_at_`bluemail.ch), and in the real-time logging record window (variant for Garmins).
- new `Display on map` button for displaying any item not mapped, in answer to a different suggestion from Harald Stauss (harald.stauss`_at_`web.de).
- new `Clear` entry in the menu that pops up with a right-button on a waypoint on the map.
- conversion of tracks into a waypoint taking the averages of the latitudes, longitudes and altitudes of the track points; this will be useful for obtaining more precise coordinates for a waypoint by recording a track with the receiver standing still; implemented in answer to a suggestion by John Madore (madore`_at_`physik.hu-berlin.de).
- when asking for a new name after a name with non-acceptable characters is read, the new name cannot be already in use.
- "single" main window no longer supported.
- support for Garmin receivers: at the time of writing there have been still no changes in the Garmin specifications document which is known to be outdated. A problem was detected with a Garmin GPS 12Map that sends some packets twice. This has been solved by discarding repeated packets, under control by a flag in the code; thanks are due to Kyle Grieser (yuf`_at_`phoenixdsl.com) for all the tests.
- the format for image information files used before version 4.0 is no longer accepted; conversion from it to the present one should be made with any version between 4.0 and 5.2.
- last but not least, there is now a separate program to convert the waypoints listed in HTML pages of the MapBlast site into GPSMan files; at its core is code contributed by Martin Ostermann (Aachen University of Technology).
