+* New features:

+      use RGB map tiles as backgrounds for further plotting.
     * `calc_haversine_distance` gains an argument `coord_units` allowing it to 
       handle coordinates in radians as well as degrees.
+* Improvements and bug fixes:
     * `georeference_overlay` provides `tempfile(fileext = ".tif")` as a default
       output location if no `output_file` is provided.
     * `get_tiles` now tells you what tiles it's retrieving, not retriving.
