• CHANGED: MapQuest geocoder removed as the API it uses is now only available
  to enterprise accounts. OpenMapQuest is a replacement for
  Nominatim-sourced data.
• CHANGED: Nominatim now uses HTTPS by default and accepts a scheme
  argument. Contributed by srounet.
• ADDED: Nominatim now accepts a domain argument, which
  allows using a different server than nominatim.openstreetmap.org.
