+Release Date: 2019-09-20
+
+* Support Python 3.8.
+* Update Cython to 0.29.13 for support Python 3.8.
+* Some small optimizations.
+
+
+0.6.1
+======
+
+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.
+
+
+0.6.0
+======
+
+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 underlying ``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)
+
+
+0.5.6
+======
+
+* 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)
+
+0.5.5
+======
+
+* Fix memory leak in pure Python Unpacker.feed() (#283)
+* Fix unpack() didn't support `raw` option (#285)
+
+0.5.4
+======
+
+* Undeprecate ``unicode_errors`` option. (#278)
+
+0.5.3
+======
+
+* Fixed regression when passing ``unicode_errors`` to Packer but not ``encoding``. (#277)
+
+0.5.2
+======
+
+* Add ``raw`` option to Unpacker.  It is preferred way than ``encoding`` option.
+
+* Packer.pack() reset buffer on exception (#274)
+
+
+0.5.1
+======
+
+* Remove FutureWarning about use_bin_type option (#271)
+
+0.5.0
+======
+
+There are some deprecations.  Please read changes carefully.
+
+Changes
+-------
+
+* Drop Python 2.6 and ~3.4 support.  Python 2.7 and 3.5+ are supported.
+
+* Deprecate useless custom exceptions.  Use ValueError instead of PackValueError,
+  Exception instead of PackException and UnpackException, etc...
+  See msgpack/exceptions.py
+
+* Add *strict_types* option to packer.  It can be used to serialize subclass of
+  builtin types.  For example, when packing object which type is subclass of dict,
+  ``default()`` is called.  ``default()`` is called for tuple too.
+
+* Pure Python implementation supports packing memoryview object.
+
+* Support packing bytearray.
+
+* Add ``Unpacker.tell()``.  And ``write_bytes`` option is deprecated.
+
+
+Bugs fixed

+
+0.3.0
+=====
+
+Incompatible Changes

+  object in single precision format.
+
+Bugs fixed
+----------
+* ``unpack()`` didn't restores gc state when it called with gc disabled.
+  ``unpack()`` doesn't control gc now instead of restoring gc state collectly.

+-------
+* Add ``max_buffer_size`` parameter to Unpacker. It limits internal buffer size
+  and allows unpack data from untrusted source safely.
+
+* Unpacker's buffer reallocation algorithm is less greedy now. It cause performance
+  decrease in rare case but memory efficient and don't allocate than ``max_buffer_size``.
+
+Bugs fixed
+----------
+* Fix msgpack didn't work on SPARC Solaris. It was because choosing wrong byteorder
+  on compilation time. Use ``sys.byteorder`` to get correct byte order.
+  Very thanks to Chris Casey for giving test environment to me.

+# MessagePack for Python
+
+[![Build Status](https://github.com/msgpack/msgpack-python/actions/workflows/wheel.yml/badge.svg)](https://github.com/msgpack/msgpack-python/actions/workflows/wheel.yml)
+[![Documentation Status](https://readthedocs.org/projects/msgpack-python/badge/?version=latest)](https://msgpack-python.readthedocs.io/en/latest/?badge=latest)
+
+## What is this?
+
+[MessagePack](https://msgpack.org/) is an efficient binary serialization format.
+It lets you exchange data among multiple languages like JSON.
+But it's faster and smaller.
+This package provides CPython bindings for reading and writing MessagePack data.
+
+## Install
+
+```
+$ pip install msgpack
+```
+
+### Pure Python implementation
+
+The extension module in msgpack (`msgpack._cmsgpack`) does not support PyPy.
+
+But msgpack provides a pure Python implementation (`msgpack.fallback`) for PyPy.
+
+
+### Windows
+
+If you can't use a binary distribution, you need to install Visual Studio
+or the Windows SDK on Windows.
+Without the extension, the pure Python implementation on CPython runs slowly.
+
+
+## How to use
+
+### One-shot pack & unpack
+
+Use `packb` for packing and `unpackb` for unpacking.
+msgpack provides `dumps` and `loads` as aliases for compatibility with
+`json` and `pickle`.
+
+`pack` and `dump` pack to a file-like object.
+`unpack` and `load` unpack from a file-like object.
+
+```pycon
+>>> import msgpack
+>>> msgpack.packb([1, 2, 3])
+'\x93\x01\x02\x03'
+>>> msgpack.unpackb(_)
+[1, 2, 3]
+```
+
+Read the docstring for options.
+
+
+### Streaming unpacking
+
+`Unpacker` is a "streaming unpacker". It unpacks multiple objects from one
+stream (or from bytes provided through its `feed` method).
+
+```py
+import msgpack
+from io import BytesIO
+
+buf = BytesIO()
+for i in range(100):
+   buf.write(msgpack.packb(i))
+
+buf.seek(0)
+
+unpacker = msgpack.Unpacker(buf)
+for unpacked in unpacker:
+    print(unpacked)
+```
+
+
+### Packing/unpacking of custom data types
+
+It is also possible to pack/unpack custom data types. Here is an example for
+`datetime.datetime`.
+
+```py
+import datetime
+import msgpack
+
+useful_dict = {
+    "id": 1,
+    "created": datetime.datetime.now(),
+}
+
+def decode_datetime(obj):
+    if '__datetime__' in obj:
+        obj = datetime.datetime.strptime(obj["as_str"], "%Y%m%dT%H:%M:%S.%f")
+    return obj
+
+def encode_datetime(obj):
+    if isinstance(obj, datetime.datetime):
+        return {'__datetime__': True, 'as_str': obj.strftime("%Y%m%dT%H:%M:%S.%f")}
+    return obj
+
+
+packed_dict = msgpack.packb(useful_dict, default=encode_datetime)
+this_dict_again = msgpack.unpackb(packed_dict, object_hook=decode_datetime)
+```
+
+`Unpacker`'s `object_hook` callback receives a dict; the
+`object_pairs_hook` callback may instead be used to receive a list of
+key-value pairs.
+
+NOTE: msgpack can encode datetime with tzinfo into standard ext type for now.
+See `datetime` option in `Packer` docstring.
+
+
+### Extended types
+
+It is also possible to pack/unpack custom data types using the **ext** type.
+
+```pycon
+>>> import msgpack
+>>> import array
+>>> def default(obj):
+...     if isinstance(obj, array.array) and obj.typecode == 'd':
+...         return msgpack.ExtType(42, obj.tostring())
+...     raise TypeError("Unknown type: %r" % (obj,))
+...
+>>> def ext_hook(code, data):
+...     if code == 42:
+...         a = array.array('d')
+...         a.fromstring(data)
+...         return a
+...     return ExtType(code, data)
+...
+>>> data = array.array('d', [1.2, 3.4])
+>>> packed = msgpack.packb(data, default=default)
+>>> unpacked = msgpack.unpackb(packed, ext_hook=ext_hook)
+>>> data == unpacked
+True
+```
+
+
+### Advanced unpacking control
+
+As an alternative to iteration, `Unpacker` objects provide `unpack`,
+`skip`, `read_array_header`, and `read_map_header` methods. The former two
+read an entire message from the stream, respectively deserializing and returning
+the result, or ignoring it. The latter two methods return the number of elements
+in the upcoming container, so that each element in an array, or key-value pair
+in a map, can be unpacked or skipped individually.
+
+
+## Notes
+
+### String and binary types in the old MessagePack spec
+
+Early versions of msgpack didn't distinguish string and binary types.
+The type for representing both string and binary types was named **raw**.
+
+You can pack into and unpack from this old spec using `use_bin_type=False`
+and `raw=True` options.
+
+```pycon
+>>> import msgpack
+>>> msgpack.unpackb(msgpack.packb([b'spam', 'eggs'], use_bin_type=False), raw=True)
+[b'spam', b'eggs']
+>>> msgpack.unpackb(msgpack.packb([b'spam', 'eggs'], use_bin_type=True), raw=False)
+[b'spam', 'eggs']
+```
+
+### ext type
+
+To use the **ext** type, pass a `msgpack.ExtType` object to the packer.
+
+```pycon
+>>> import msgpack
+>>> packed = msgpack.packb(msgpack.ExtType(42, b'xyzzy'))
+>>> msgpack.unpackb(packed)
+ExtType(code=42, data='xyzzy')
+```
+
+You can use it with `default` and `ext_hook`. See below.
+
+
+### Security
+
+When unpacking data received from an unreliable source, msgpack provides
+two security options.
+
+`max_buffer_size` (default: `100*1024*1024`) limits the internal buffer size.
+It is also used to limit preallocated list sizes.
+
+`strict_map_key` (default: `True`) limits the type of map keys to bytes and str.
+While the MessagePack spec doesn't limit map key types,
+there is a risk of a hash DoS.
+If you need to support other types for map keys, use `strict_map_key=False`.
+
+
+### Performance tips
+
+CPython's GC starts when the number of allocated objects grows.
+This means unpacking may trigger unnecessary GC.
+You can use `gc.disable()` when unpacking a large message.
+
+A list is the default sequence type in Python.
+However, a tuple is lighter than a list.
+You can use `use_list=False` while unpacking when performance is important.
+
+
+## Major breaking changes in the history
+
+### msgpack 0.5
+
+The package name on PyPI was changed from `msgpack-python` to `msgpack` in 0.5.
+
+When upgrading from msgpack-0.4 or earlier, do `pip uninstall msgpack-python` before
+`pip install -U msgpack`.
+
+
+### msgpack 1.0
+
+* Python 2 support
+
+  * The extension module no longer supports Python 2.
+    The pure Python implementation (`msgpack.fallback`) is used for Python 2.
+  
+  * msgpack 1.0.6 drops official support of Python 2.7, as pip and
+    GitHub Action "setup-python" no longer supports Python 2.7.
+
+* Packer
+
+  * Packer uses `use_bin_type=True` by default.
+    Bytes are encoded in the bin type in MessagePack.
+  * The `encoding` option is removed. UTF-8 is always used.
+
+* Unpacker
+
+  * Unpacker uses `raw=False` by default. It assumes str values are valid UTF-8 strings
+    and decodes them to Python str (Unicode) objects.
+  * `encoding` option is removed.  You can use `raw=True` to support old format (e.g. unpack into bytes, not str).
+  * The default value of `max_buffer_size` is changed from 0 to 100 MiB to avoid DoS attacks.
+    You need to pass `max_buffer_size=0` if you have large but safe data.
+  * The default value of `strict_map_key` is changed to True to avoid hash DoS.
+    You need to pass `strict_map_key=False` if you have data that contain map keys
+    whose type is neither bytes nor str.

+Packer
+------
+
+autoreset
+~~~~~~~~~
+
+When you used ``autoreset=False`` option of :class:`~msgpack.Packer`, 
+``pack()`` method doesn't return packed ``bytes``.
+
+You can use :meth:`~msgpack.Packer.bytes` or :meth:`~msgpack.Packer.getbuffer` to
+get packed data.
+
+``bytes()`` returns ``bytes`` object.  ``getbuffer()`` returns some bytes-like
+object.  It's concrete type is implement detail and it will be changed in future
+versions.
+
+You can reduce temporary bytes object by using ``Unpacker.getbuffer()``.
+
+.. code-block:: python
+
+    packer = Packer(use_bin_type=True, autoreset=False)
+
+    packer.pack([1, 2])
+    packer.pack([3, 4])
+
+    with open('data.bin', 'wb') as f:
+        f.write(packer.getbuffer())
+
+    packer.reset()  # reset internal buffer

+    :param default:
+        When specified, it should be callable.
+        Convert user type to builtin type that Packer supports.
+        See also simplejson's document.
+
+    :param bool use_single_float:
+        Use single precision float type for float. (default: False)
+
+    :param bool autoreset:
+        Reset buffer after each pack and return its content as `bytes`. (default: True).
+        If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+    :param bool use_bin_type:
+        Use bin type introduced in msgpack spec 2.0 for bytes.
+        It also enables str8 type for unicode. (default: True)
+
+    :param bool strict_types:
+        If set to true, types will be checked to be exact. Derived classes
+        from serializeable types will not be serialized and will be
+        treated as unsupported type and forwarded to default.
+        Additionally tuples will not be serialized as lists.
+        This is useful when trying to implement accurate serialization
+        for python types.
+
+    :param bool datetime:
+        If set to true, datetime with tzinfo is packed into Timestamp type.
+        Note that the tzinfo is stripped in the timestamp.
+        You can get UTC datetime with `timestamp=3` option of the Unpacker.
+
+    :param str unicode_errors:
+        The error handler for encoding unicode. (default: 'strict')
+        DO NOT USE THIS!!  This option is kept for very specific usage.
+
+    :param int buf_size:
+        The size of the internal buffer. (default: 256*1024)
+        Useful if serialisation size can be correctly estimated,
+        avoid unnecessary reallocations.

+        When specified, it should be callable.
+        Convert user type to builtin type that Packer supports.
+        See also simplejson's document.
+
+    :param bool use_single_float:
+        Use single precision float type for float. (default: False)
+
+    :param bool autoreset:
+        Reset buffer after each pack and return its content as `bytes`. (default: True).
+        If set this to false, use `bytes()` to get content and `.reset()` to clear buffer.
+
+    :param bool use_bin_type:
+        Use bin type introduced in msgpack spec 2.0 for bytes.
+        It also enables str8 type for unicode. (default: True)
+
+    :param bool strict_types:
+        If set to true, types will be checked to be exact. Derived classes
+        from serializable types will not be serialized and will be
+        treated as unsupported type and forwarded to default.
+        Additionally tuples will not be serialized as lists.
+        This is useful when trying to implement accurate serialization
+        for python types.
+
+    :param bool datetime:
+        If set to true, datetime with tzinfo is packed into Timestamp type.
+        Note that the tzinfo is stripped in the timestamp.
+        You can get UTC datetime with `timestamp=3` option of the Unpacker.
+
+    :param str unicode_errors:
+        The error handler for encoding unicode. (default: 'strict')
+        DO NOT USE THIS!!  This option is kept for very specific usage.
