2.0.0

Added

• orjson.dumps() accepts a default callable to serialize arbitrary
  types.
• orjson.dumps() accepts datetime.datetime, datetime.date,
  and datetime.time. Each is serialized to an RFC 3339 string.
• orjson.dumps(..., option=orjson.OPT_NAIVE_UTC) allows serializing
  datetime.datetime objects that do not have a timezone set as UTC.
• orjson.dumps(..., option=orjson.OPT_STRICT_INTEGER) available to
  raise an error on integer values outside the 53-bit range of all JSON
  implementations.

Changed

• orjson.dumps() no longer accepts bytes.
