v8.1

New in version 8

• Added NEWS.md file
• Rationalised keyword usage in Fortran API. See Input/Output query parameters
  documentation for the updated reference.
• Added Message, Importer, Exporter, File, DB, Transaction, Cursor*, Data,
  Values to the C++ stable API
• Dropped support for Python 2
• Dropped support for unused AOF format
• Renamed fortran API functions with self-explanatory English names. The old
  names are kept as aliases for compatibility with existing/old Fortran code
• Implemented dbadb --varlist
• Python API changes:
  • Added dballe.Message
  • Added dballe.Importer
  • Added dballe.Exporter
  • Added dballe.File
  • Added dballe.Explorer
  • Removed dballe.Record in favour of using dict() for input, and using
    Cursor*.__getitem__ for output.
  • Renamed Cursor*.attr_query to Cursor*.query_attrs
  • Added Cursor*.insert_attrs
  • Added Cursor*.remove_attrs
  • Added Cursor*.remove()
  • Added DB.query_messages
  • DB or Transaction: .query_*: query argument is now optional, omit it to
    query everything
  • Added Cursor.query and Cursor.data
  • Allow to pass a Cursor instead of a dict to insert_data and
    insert_station_data, to efficiently copy data between databases.
  • Deprecated DB.insert_station_data, DB.insert_data,
    DB.remove_station_data, DB.remove_data, DB.query_stations,
    DB.query_station_data, DB.query_data, DB.query_summary,
    DB.query_messages, DB.attr_query_station, DB.attr_query_data,
    DB.attr_insert_station, DB.attr_insert_data, DB.attr_remove_station,
    DB.attr_remove_data.
    Use the same methods in dballe.Transaction instead.
• The use of ?wipe is now documented and supported
  in C++, Python, Fortran, and command line. The value of wipe is now parsed
  to prevent unexpectedly clearing a database when using something like
  ?wipe=no.
