Sourced from msgpack's changelog.

1.2.3

Release Date: 2026-09-29

  • Fix memory leaks in the C extension when map key validation or container hooks fail. See GHSA-j586-36cw-2gc2.
  • Fix use-after-free errors when cleaning up an incomplete or failed Unpacker.skip() after previously unpacking a nested object in the C extension.
  • Raise ValueError in the C extension when switching between unpacking, skipping, header readers, or read_bytes() while an object is incomplete. Resume with the same method after feeding more data; unpack() and iteration remain interchangeable.
  • Prevent reentrant unpacking, header reads, read_bytes(), and reinitialization of the same C Unpacker while unpacking is in progress.
  • Reject negative sizes in Packer.pack_array_header() and Packer.pack_map_header(). #742
  • Support packing Python 3.15 frozendict objects. #738
  • Update Cython from 3.2.5 to 3.3.0. #738
  • Build wheels for Pyodide using Emscripten. #732
  • Update cibuildwheel to 4.2.1 and the QEMU setup action to 4.4.0. #741

1.2.2

Release Date: 2026-08-27

  • Fix the read_size documentation. #700
  • Fix silent truncation when unpacking an out-of-range timestamp with timestamp=3. #701
  • Prevent reentrant calls to Unpacker.feed() while unpacking. #704
  • Improve error handling and reporting in unpacking functions. #707
  • Fix Timestamp.from_datetime() precision for far-future datetimes. #710
  • Fix typos in the documentation. #712
  • Validate the nanoseconds range when unpacking timestamps in the C extension. #716
  • Fix a use-after-free in the unpackb() ExtraData path for non-contiguous input. #722
  • Prevent a buffer overflow when converting Packer's buf_size. #726
  • Translate RecursionError to StackError in the fallback Unpacker.skip(). #727
  • Raise OverflowError when use_single_float=True cannot represent a value. #728
