Msgpack-sorted

=====

Release Date: 2019-09-20

* Support Python 3.8.
* Update Cython to 0.29.13 for support Python 3.8.
* Some small optimizations.

======

Release Date: 2019-01-25

This release is for mitigating pain caused by v0.6.0 reduced max input limits
for security reason.

* ``unpackb(data)`` configures ``max_*_len`` options from ``len(data)``,
instead of static default sizes.

* ``Unpacker(max_buffer_len=N)`` configures ``max_*_len`` options from ``N``,
instead of static default sizes.

* ``max_bin_len``, ``max_str_len``, and ``max_ext_len`` are deprecated.
Since this is minor release, it's document only deprecation.

======

Release Date: 2018-11-30

This release contains some backward incompatible changes for security reason (DoS).

Important changes
-----------------

* unpacker: Default value of input limits are smaller than before to avoid DoS attack.
If you need to handle large data, you need to specify limits manually. (319)

* Unpacker doesn't wrap underlaying ``ValueError`` (including ``UnicodeError``) into
``UnpackValueError``. If you want to catch all exception during unpack, you need
to use ``try ... except Exception`` with minimum try code block. (323, 233)

* ``PackValueError`` and ``PackOverflowError`` are also removed. You need to catch
normal ``ValueError`` and ``OverflowError``. (323, 233)

* Unpacker has ``strict_map_key`` option now. When it is true, only bytes and str
(unicode in Python 2) are allowed for map keys. It is recommended to avoid
hashdos. Default value of this option is False for backward compatibility reason.
But it will be changed True in 1.0. (296, 334)

Other changes
-------------

* Extension modules are merged. There is ``msgpack._cmsgpack`` instead of
``msgpack._packer`` and ``msgpack._unpacker``. (314, 328)

* Add ``Unpacker.getbuffer()`` method. (320)

* unpacker: ``msgpack.StackError`` is raised when input data contains too
nested data. (331)

* unpacker: ``msgpack.FormatError`` is raised when input data is not valid
msgpack format. (331)

======

* Fix fallback.Unpacker.feed() dropped unused data from buffer (287)
* Resurrect fallback.unpack() and _unpacker.unpack().
They were removed at 0.5.5 but it breaks backward compatibility. (288, 290)

======

* Fix memory leak in pure Python Unpacker.feed() (283)
* Fix unpack() didn't support `raw` option (285)

======

* Undeprecate ``unicode_errors`` option. (278)
