• JsonSerializable compatibility interface was moved to GeoIp2\Compat
  rather than the global namespace to prevent autoloading issues. Reported by
  Tomas Buteler. GitHub #54.
• Missing documentation for the $postal property was added to the
  GeoIp2\Model\City class. Fix by Roy Sindre Norangshol. GitHub #51.
• In the Phar distribution, source files for this module no longer have their
  documentation stripped, allowing IDE introspection to work properly.
