Renamed MGLStyleCurrentVersion to MGLStyleDefaultVersion to emphasize the constant’s role as an indicator of the default version used by SDK classes, which may be behind depending on release schedules. In the documentation for each style URL method, include the actual version number instead of the constant. In unit tests, verify that this documentation is in sync with the constant. Link each style URL method’s documentation to a forthcoming webpage on mapbox.com that describes the style in rich detail.
