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

  • Fixed zero length raw can't be decoded when encoding is specified. (#236)

0.4.8

release date:2016-07-29

Bugs fixed

  • Calling ext_hook with wrong length. (Only on Windows, maybe. #203)

0.4.7

release date:2016-01-25

Bugs fixed

  • Memory leak when unpack is failed

Changes

  • Reduce compiler warnings while building extension module
  • unpack() now accepts ext_hook argument like Unpacker and unpackb()
  • Update Cython version to 0.23.4
  • default function is called when integer overflow

0.4.6

release date:2015-03-13

Bugs fixed

  • fallback.Unpacker: Fix Data corruption when OutOfData. This bug only affects "Streaming unpacking."

0.4.5

release date:2015-01-25

Incompatible Changes

Changes

Bugs fixed

  • Fix test failure on pytest 2.3. (by @ktdreyer)
  • Fix typos in ChangeLog. (Thanks to @dmick)
  • Improve README.rst (by @msabramo)

0.4.4

release date:2015-01-09

Incompatible Changes

Changes

Bugs fixed

  • Fix compile error.

0.4.3

release date:2015-01-07

Incompatible Changes

Changes

Bugs fixed

  • Unpacker may unpack wrong uint32 value on 32bit or LLP64 environment. (#101)
  • Build failed on Windows Python 2.7.

0.4.2

release date:2014-03-26

Incompatible Changes

Changes

Bugs fixed

  • Unpacker doesn't increment refcount of ExtType hook.
  • Packer raises no exception for inputs doesn't fit to msgpack format.

0.4.1

release date:2014-02-17

Incompatible Changes

Changes

  • fallback.Unpacker.feed() supports bytearray.

Bugs fixed

  • Unpacker doesn't increment refcount of hooks. Hooks may be GCed while unpacking.
  • Unpacker may read unfilled internal buffer.

0.4.0

release date:2013-10-21

Incompatible Changes

  • Raises TypeError instead of ValueError when packer receives unsupported type.

Changes

  • Support New msgpack spec.

0.3.0

Incompatible Changes

  • Default value of use_list is True for now. (It was False for 0.2.x) You should pass it explicitly for compatibility to 0.2.x.
  • Unpacker.unpack() and some unpack methods now raise OutOfData instead of StopIteration. StopIteration is used for iterator protocol only.

Changes

  • Pure Python fallback module is added. (thanks to bwesterb)
  • Add .skip() method to Unpacker (thanks to jnothman)
  • Add capturing feature. You can pass the writable object to Unpacker.unpack() as a second parameter.
  • Add Packer.pack_array_header and Packer.pack_map_header. These methods only pack header of each type.
  • Add autoreset option to Packer (default: True). Packer doesn't return packed bytes and clear internal buffer.
  • Add Packer.pack_map_pairs. It packs sequence of pair to map type.

0.2.4

release date:2012-12-22

Bugs fixed

  • Fix SEGV when object_hook or object_pairs_hook raise Exception. (#39)

0.2.3

release date:2012-12-11

Changes

  • Warn when use_list is not specified. It's default value will be changed in 0.3.

Bugs fixed

  • Can't pack subclass of dict.

0.2.2

release date:2012-09-21

Changes

  • Add use_single_float option to Packer. When it is true, packs float 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. User can control gc state when gc cause performance issue.
  • Unpacker's read_size option didn't used.

0.2.1

release date:2012-08-20

Changes

  • 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.

0.2.0

release date:2012-06-27

Changes

  • Drop supporting Python 2.5 and unify tests for Py2 and Py3.
  • Use new version of msgpack-c. It packs correctly on big endian platforms.
  • Remove deprecated packs and unpacks API.

Bugs fixed

  • #8 Packing subclass of dict raises TypeError. (Thanks to Steeve Morin.)

0.1.13

release date:2012-04-21

New

  • Don't accept subtype of list and tuple as msgpack list. (Steeve Morin) It allows customize how it serialized with default argument.

Bugs fixed

  • Fix wrong error message. (David Wolever)
  • Fix memory leak while unpacking when object_hook or list_hook is used. (Steeve Morin)

  • setup.py works on Python 2.5 (Steffen Siering)
  • Optimization for serializing dict.

0.1.12

release date:2011-12-27

Bugs fixed

  • Re-enable packs/unpacks removed at 0.1.11. It will be removed when 0.2 is released.

0.1.11

  • Fix compilation error on MSVC. (davidgaleano)

0.1.10

release date:2011-08-22

New feature

  • Add encoding and unicode_errors option to packer and unpacker. When this option is specified, (un)packs unicode object instead of bytes. This enables using msgpack as a replacement of json. (tailhook)

0.1.9

release date:2011-01-29

New feature

  • use_list option is added to unpack(b) like Unpacker. (Use keyword argument because order of parameters are different)

0.1.8

release date:2011-01-10

New feature

  • Support loads and dumps aliases for API compatibility with simplejson and pickle.
  • Add object_hook and list_hook option to unpacker. It allows you to hook unpacking mapping type and array type.
  • Add default option to packer. It allows you to pack unsupported types.
  • unpacker accepts (old) buffer types.

Bugs fixed

  • Fix segv around Unpacker.feed or Unpacker(file).

0.1.7

release date:2010-11-02

New feature

  • Add object_hook and list_hook option to unpacker. It allows you to hook unpacking mapping type and array type.
  • Add default option to packer. It allows you to pack unsupported types.
  • unpacker accepts (old) buffer types.
