Sourced from cbor2's releases.

5.6.5

• Published binary wheels for Python 3.13

5.6.4

• Fixed compilation of C extension failing on GCC 14
• Fixed compiler warnings when building C extension

5.6.3

• Fixed decoding of epoch-based dates being affected by the local time zone in the C extension

5.6.2

• Fixed __hash__() of the C version of the CBORTag type crashing when there's a recursive reference cycle
• Fixed type annotation for the file object in cbor2.dump(), cbor2.load(), CBOREncoder and CBORDecoder to be IO[bytes] instead of BytesIO
• Worked around a CPython bug that caused a SystemError to be raised, or even a buffer overflow to occur when decoding a long text string that contained only ASCII characters
• Changed the return type annotations of cbor2.load() and cbor2.load() to return Any instead of object so as not to force users to make type casts

5.6.1

• Fixed use-after-free in the decoder's C version when prematurely encountering the end of stream
• Fixed the C version of the decoder improperly raising CBORDecodeEOF when decoding a text string longer than 65536 bytes

5.6.0

• Added the cbor2 command line tool (for pipx run cbor2)
• Added support for native date encoding (bschoenmaeckers)
• Made the C extension mandatory when the environment variable CBOR2_BUILD_C_EXTENSION is set to 1.
• Fixed SystemError in the C extension when decoding a Fractional with a bad number of arguments or a non-tuple value
• Fixed SystemError in the C extension when the decoder object hook raises an exception
• Fixed a segmentation fault when decoding invalid unicode data
• Fixed infinite recursion when trying to hash a CBOR tag whose value points to the tag itself
• Fixed MemoryError when maliciously constructed bytestrings or string (declared to be absurdly large) are being decoded
• Fixed UnicodeDecodeError from failed parsing of a UTF-8 text string not being wrapped as CBORDecodeValueError
• Fixed TypeError or ZeroDivisionError from a failed decoding of Fraction not being wrapped as CBORDecodeValueError
• Fixed TypeError or ValueError from a failed decoding of UUID not being wrapped as CBORDecodeValueError
• Fixed TypeError from a failed decoding of MIMEMessage not being wrapped as CBORDecodeValueError
• Fixed OverflowError, OSError or ValueError from a failed decoding of epoch-based datetime not being wrapped as CBORDecodeValueError

5.5.1

• Fixed CBORSimpleValue allowing the use of reserved values (24 to 31) which resulted in invalid byte sequences
• Fixed encoding of simple values from 20 to 23 producing the wrong byte sequences

5.5.0

• The cbor2.encoder, cbor2.decoder or cbor2.types modules were deprecated – import their contents directly from cbor2 from now on. The old modules will be removed in the next major release.
• Added support for Python 3.12
• Added type annotations
• Dropped support for Python 3.7
• Fixed bug in the fp attribute of the built-in version of CBORDecoder and CBOREncoder where the getter returns an invalid pointer if the read method of the file was a built-in method

version 5.4.6

• Fix a tag decoding error

version 5.4.5
