• Jackson now uses the constructors on model classes when mapping JSON and
  database records to them rather than overriding the access modifiers on
  them. Pull request by Martijn van Groningen. GitHub #51 & #52.
• The format of the output of the toString() methods in the models has
  changed to better represent the values returned by the databases and web
  services. toString() should be only used for debugging and diagnostics.
  Do not try to parse it. If you want the contents of the model as a machine-
  readable string, use toJson().
• This release depends on version 1.0.1 of the MaxMind DB reader, which
  includes several performance enhancements from by Viktor Szathmáry.
