What's Changed

Added

Add support for Python 3.14, including 3.14t (no-GIL) wheels. However, thread safety for the no-GIL variant is not fully tested yet. Please report any issues you encounter (#134, #136).
Add support for Android (Python 3.13 only) and iOS (Python 3.13 and 3.14) wheels, enabled by the major version update of cibuildwheel (#135).

What's Changed

Added

Improve the performance of hash128(), hash64(), and hash_bytes() by using METH_FASTCALL, reducing the overhead of function calls (#116).
Add the software paper for this library (doi:10.21105/joss.06124), following its publication in the Journal of Open Source Software (#118).

Removed

Drop support for Python 3.8, as it has reached the end of life on 2024-10-07 (#117).

Published by hajimes over 2 years ago

What's Changed

Add experimental support for hashlib-compliant hasher classes (https://github.com/hajimes/mmh3/issues/39). Note that they are not yet fully tuned for performance.
Add support for type hints (https://github.com/hajimes/mmh3/issues/44).
Add wheels for more platforms (musllinux, s390x, win_arm64, and macosx_universal2).
Drop support for Python 3.7, as it will reach the end of life on 2023-06-27.
Switch license from CC0 to MIT (https://github.com/hajimes/mmh3/issues/43).
Add a code of conduct (the ACM Code of Ethics and Professional Conduct).
Backward incompatible changes:
- A hash function now returns the same value under big-endian platforms as that under little-endian ones (https://github.com/hajimes/mmh3/issues/47).
- Remove the __version__ constant from the module (https://github.com/hajimes/mmh3/issues/42). Use importlib.metadata instead.

What's Changed

Add hash128, which returns a 128-bit signed integer.
Fix a misplaced operator which could cause memory leak in a rare condition.
Fix a malformed value to a Python/C API function which may cause runtime errors in recent Python 3.x versions.

The first two commits are from Derek Wilson. Thanks!

Scientific Software - Peer-reviewed - C
Published by hajimes almost 3 years ago

What's Changed

Add __version__ constant. Check if it exists when the following revision matters for your application.
Incorporate the revision r147, which includes robustness improvement and minor tweaks.

Beware that due to this revision, the result of 32-bit version of 2.1 is NOT the same as that of 2.0. E.g.,:

```shell

mmh3.hash("foo") # in mmh3 2.0 -292180858 mmh3.hash("foo") # in mmh3 2.1 -156908512 ```

The results of hash64 and hash_bytes remain unchanged. Austin Appleby, the author of Murmurhash, ensured this revision was the final modification to MurmurHash3's results and any future changes would be to improve performance only.
