4.0.012 Aug 2026Breaking
Breaking change : Drop support for Python 3.8, require Python >= 3.9
Breaking change: Drop support for Python 3.8, require Python >= 3.9

Breaking change: Remove deprecated xxhash.VERSION_TUPLE

Breaking change: The input keyword argument is renamed to data
across constructors, update(), and one-shot functions

Breaking change: str input is no longer accepted and raises
TypeError: Strings must be encoded before hashing; encode to
bytes before hashing

Upgrade xxHash from v0.8.2 to v0.8.3. Note: on GCC/Clang source builds
that target AVX2 (e.g. -march=x86-64-v3), upstream v0.8.3
autovectorizes XXH64_update() and makes the xxh64 streaming path
about 2x slower. The shipped wheels are built for baseline x86-64 and
are unaffected. Source builds can work around it by adding
-fno-tree-vectorize to the compiler flags.

Add per-object locking for thread safety, with sub-interpreter and
free-threaded (no-GIL) Python support

Speed up hash constructors by switching them to tp_vectorcall.

Build pyodide wasm32 wheels

Add s390x big-endian test job

Add Python 3.15 classifier

CI: shard the PyPI upload into parallel groups and create the GitHub
Release automatically

One column per quarter.

Breaking change: Drop support for Python 3.8, require Python >= 3.9
Breaking change: Remove deprecated xxhash.VERSION_TUPLE
Breaking change: The input keyword argument is renamed to data in constructors and one-shot functions. update() additionally gains a data keyword argument (it accepted no keyword arguments before).
Breaking change: str input is no longer accepted and raises TypeError: Strings must be encoded before hashing; encode to bytes before hashing
Upgrade xxHash from v0.8.2 to v0.8.3. Note: on GCC/Clang source builds that target AVX2 (e.g. -march=x86-64-v3), upstream v0.8.3 autovectorizes XXH64_update() and makes the xxh64 streaming path about 2x slower.

Add per-object locking for thread safety, with sub-interpreter and free-threaded (no-GIL) Python support. The GIL is now released only while hashing inputs larger than 64 KiB; previously update() released it unconditionally and one-shot functions always held it.

Speed up module-level one-shot digest() , intdigest() , and hexdigest() functions by switching them to METH_FASTCALL .

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.
