2.1.0 - New topo map option (using OpenCycleMap.org, topographic data available between 60°N and 47°S) - Minor fixes Note: topo maps do not offer zoom levels as high as the other map types. If you zoom beyond the maximum level available, a hybrid map will be displayed instead. See Help/Settings for more information.
