3.3.1

Fixed

• Fix failure to deserialize some latin1 strings on some platforms. This
  was introduced in 3.2.0.
• Fix annotation of optional parameters on orjson.dumps() for help().

Changed

• Publish manylinux2014 wheels for amd64 in addition to manylinux1.

3.3.0

Added

• orjson.dumps() now serializes individual numpy floats and integers, e.g.,
  numpy.float64(1.0).
• orjson.OPT_PASSTHROUGH_DATACLASS causes orjson.dumps() to pass
  dataclasses.dataclass instances to default.

3.2.2

Fixed

• Fix serializing dataclasses.dataclass that have no attributes.

Changed

• Improve deserialization performance of str.

3.2.1

Fixed

• Fix orjson.dumps(..., **{}) raising TypeError on python3.6.

3.2.0

Added

• orjson.OPT_APPEND_NEWLINE appends a newline to output.

Changed

• Improve deserialization performance of str.

3.1.2

Fixed

• Fix serializing zero-dimension numpy.ndarray.

3.1.1

Fixed

• Fix repeated serialization of str that are ASCII-only and have a legacy
  (non-compact) layout.

3.1.0

Added

• orjson.OPT_PASSTHROUGH_SUBCLASS causes orjson.dumps() to pass
  subclasses of builtin types to default so the caller can customize the
  output.
• orjson.OPT_PASSTHROUGH_DATETIME causes orjson.dumps() to pass
  datetime objects to default so the caller can customize the
  output.

3.0.2

Changed

• orjson.dumps() does not serialize dataclasses.dataclass attributes
  that begin with a leading underscore, e.g., _attr. This is because of the
  Python idiom that a leading underscores marks an attribute as "private."
• orjson.dumps() does not serialize dataclasses.dataclass attributes that
  are InitVar or ClassVar whether using __slots__ or not.

3.0.1

Fixed

• orjson.dumps() raises an exception if the object to be serialized
  is not given as a positional argument. orjson.dumps({}) is intended and ok
  while orjson.dumps(obj={}) is an error. This makes it consistent with the
  documentation, help() annotation, and type annotation.
• Fix orphan reference in exception creation that leaks memory until the
  garbage collector runs.

Changed

• Improve serialization performance marginally by using the fastcall/vectorcall
  calling convention on python3.7 and above.
• Reduce build time.
