Changelog

Sourced from xxhash's changelog.

v3.8.1 2026-07-06

- Register the "benchmark" pytest mark to avoid PytestUnknownMarkWarning
- Update C extension docstrings and remove stale comments
v3.8.0 2026-06-27

• Speed up module-level one-shot digest(), intdigest(), and hexdigest() functions by switching them to METH_FASTCALL.
• Keep one-shot argument handling consistent with hash constructors, including positional and keyword input/seed arguments, duplicate argument errors, and oversized seed wrapping.
• Fix error handling in the xxh3_128 integer digest path so allocation failures are reported cleanly.
• Fix Python 3.8 builds by adding a PyModule_AddType compatibility fallback with correct reference counting.
• Correct type stubs for xxh64_digest(), xxh64_hexdigest(), and xxh64_intdigest(), they were incorrectly aliased to xxh3_64 functions.

v3.7.2 2026-07-06

- Register the "benchmark" pytest mark to avoid PytestUnknownMarkWarning
- Update C extension docstrings and remove stale comments
v3.7.1 2026-06-24

• Fix memory leak in copy() and new() when memory allocation fails (rare edge case)
• Fix seed/reset state initialization in xxh32 and xxh64 (unlikely to affect normal usage)
• Replace Py_BuildValue with PyLong_FromUnsignedLong/LongLong for performance
• Update README examples to use bytes literals
• Add CodSpeed performance benchmarks and CI workflow
• Build aarch64/armv7l on native Arm runners; test against Python 3.15.0-beta.2
