Changelog

Sourced from bitarray's changelog.

Change log

3.10.0 (2026-07-31):

• add free threading support <free_threading.rst>__
• add bitarray/test_free_threading.py - these free-threading tests are imported when Python was compiled using --disable-gil
• add official support for decodetree methods .nodes() and .todict()
• util.huffman_code() and util.canonical_huffman() return codedicts mapping symbols to frozenbitarrays
• fix free-threading bug in binode_make_tree()
• use a private capsule to safely share the bitarray type between the _bitarray and _util extension modules
• bitarrays in prefix codes passed to .decode() or decodetree() cannot exceed 256 bits
• the following methods/functions also accept a frozendict (added in Python 3.15): .decode(), decodetree(), .encode(), util.huffman_code() and util.canonical_huffman()
• make C code more cohesive

3.9.2 (2026-07-25):

• add more critical sections in Python-facing operations
• optimize mask indexing operations for sparse and dense masks
• move tests for internal _ssqi() to devel/test_sum_indices.py
• remove all occurrences of PySlice_GetIndicesEx (deprecated since Python 3.6.1)

3.9.1 (2026-07-19):

• improving free-threading readiness, see also [#251](https://github.com/ilanschnell/bitarray/issues/251) <https://github.com/ilanschnell/bitarray/issues/251>__:
  • initialize tables at module import, not lazily
  • remove caching imported Python objects (which are already caches)
  • added 75 critical sections in Python-facing operations
  • updated Trove Classifier to Free Threading :: 2 - Beta
• clip arguments in .bytereverse() instead of raising IndexError
• remove ssize_richcompare() in favor of Py_RETURN_RICHCOMPARE macro
• add tests for frozenbitarrays created by methods when self is a frozenbitarray, e.g. slicing a frozenbitarray

3.9.0 (2026-07-10):

• add .rotate() method, rotate bitarray in-place by k positions
• expose the decodeiterator class, and add .skipbits() method as well as .index data descriptor, see [#252](https://github.com/ilanschnell/bitarray/issues/252) <https://github.com/ilanschnell/bitarray/issues/252>__
• fix random_p() silently producing all-zero bitarrays for small n
