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

• 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
