            "1.01 (2005-02-15) added cleanUp() method to map and dragObj objects, some fixes in the documentation\n"
            "1.02 (2005-02-20) fixed problems with double clicks, the second click of a double click is now ignored, using the evt.detail property\n"
            "1.03 (2005-02-22) introduced timestamp and nrLayerToLoad array for dynamic loading (getUrl)\n"
            "1.04 (2005-09-15) introduced a few changes with coordinate calculation to support MozillaSVG, introduced epsg and unitsFactor property based on a suggestion by Bruce Rindahl\n"
            "1.1 (2005-10-05) introduced button object (see button.js file), introduced zoom and pan \"modes\" for repeated actions in the same mode, introduced history of map extents with the ability to go back and forth in the list of previous map extents, some internal changes in the code (e.g. less global variables), added experimental support for the batik SVG 1.2 \"static\" attribute to improve performance while panning the map, added cursors to give better status feedback\n"
