2.6.1

Changed

• Serialization is 10-20% faster and uses about 50% less memory by writing
  directly to the returned bytes object.

2.6.0

Added

• orjson.dumps() pretty prints with an indentation of two spaces if
  option=orjson.OPT_INDENT_2 is specified.

2.5.2

Changed

• Publish manylinux2014 wheels for aarch64.
• numpy support now includes numpy.uint32 and numpy.uint64.

2.5.1

Changed

• manylinux1 wheels for 3.6, 3.7, and 3.8 are now compliant with the spec by
  not depending on glibc 2.18.

2.5.0

Added

• orjson.dumps() serializes dict keys of type other than str if
  option=orjson.OPT_NON_STR_KEYS is specified.

2.4.0

Added

• orjson.dumps() serializes numpy.ndarray instances if
  option=orjson.OPT_SERIALIZE_NUMPY is specified.

Fixed

• Fix dataclasses.dataclass attributes that are dict to be effected by
  orjson.OPT_SORT_KEYS.

2.3.0

Added

• orjson.dumps() serializes dict instances sorted by keys, equivalent to
  sort_keys in other implementations, if option=orjson.OPT_SORT_KEYS is
  specified.

Changed

• dataclasses.dataclass instances without __slots__ now serialize faster.

Fixed

• Fix documentation on default, in particular documenting the need to raise
  an exception if the type cannot be handled.

2.2.2

Changed

• Performance improvements to serializing a list containing elements of the
  same type.

2.2.1

Fixed

• orjson.loads() rejects floats that do not have a digit following
  the decimal, e.g., -2., 2.e-3.

Changed

• Build Linux, macOS, and Windows wheels on more recent distributions.

2.2.0

Added

• orjson.dumps() serializes uuid.UUID instances if
  option=orjson.OPT_SERIALIZE_UUID is specified.

Changed
