I'm using an older version. Do the new versions have built-in support for the new (?) imagerySet values? If not, how would I add them? I've used my own or inherited versions of OSM classes, but the Bing classes are more complex and have more levels of inheritance. Below is the documentation for the static map, but I don't know if this applies to Tiles, too.
