## Version 6.4.1 -- 30 December 2009

- complete revision to avoid problems in dealing with toplevel windows caused by a bug in the Gnome Metacity window manager; thanks to Sergei Golovan.

- accurate formulae for computing distances and bearings are now the default and should be used except on very slow computers; most users should select them when upgrading; thanks to Valère Robin.

- full support for TFW files following the description available from the ESRI site; with the help of Jim McGuire (jxmcguire1`_at_`ualr.edu).

- fonts can now be fully configured, with real-time configuration for map and plots fonts; font sizes selected in previous versions will not be considered when upgrading and manual selection is needed; in answer to a suggestion from Paul Gogan (pgmail`_at_`gogan.org).

- user-defined methods for renaming waypoints; after a suggestion by Zvi Grauer.

- changes in group window, suggested by Zvi Grauer: element names are coloured depending on being in the data-base (only updated when clicking or double-clicking on them), more than one element can be selected.

- tentative support for importation of waypoints from points of interest in MapEdit Polish format files; asked by Zvi Grauer.

- information on a waypoint can be sent to a Twitter account if the `TclCurl` library is available; with thanks to Zvi Grauer for his PHP script to do a similar thing.

- GPSMan can now be extended through pre- and user-defined plug-ins coded in Tcl/Tk.

- patch files may now change the procedures that set up the interface and initialise global variables.

- explicit support for some new Garmin receivers; with thanks to Ken Stephens, Geoff, Elven Decker, Bill Rainey, Thomas D. Dean, Mark N. Reihart, Pekka Ahoi, Alex Preobrazhenskiy and Mario Borgnia who sent protocol lists.
