- Linux x86_64: add cp310, cp311, cp313 (.so), built in conda-forge envs. - Windows AMD64: add cp310, cp311, cp313 (.pyd), built with MSVC v14.50. - All eight binaries verified to produce identical numerical output. - README compatibility table + build provenance updated. - macOS still deferred.

# Changelog
|
|
|
|
All notable changes to `sem_cython12` are recorded in this file.
|
|
|
|
The project follows [Semantic Versioning](https://semver.org/): a
|
|
release `MAJOR.MINOR.PATCH` increments
|
|
|
|
- `MAJOR` on breaking API changes,
|
|
- `MINOR` on backwards-compatible feature additions,
|
|
- `PATCH` on backwards-compatible bug fixes.
|
|
|
|
## [1.1.0] - 2026-05-10
|
|
|
|
Binary matrix expanded to four CPython versions on both supported
|
|
platforms.
|
|
|
|
### Added
|
|
|
|
- Pre-compiled Linux x86_64 binaries for **CPython 3.10, 3.11, 3.13**
|
|
(`sem_core12.cpython-3{10,11,13}-x86_64-linux-gnu.so`). Built in
|
|
isolated conda-forge environments with conda-forge gcc, same
|
|
OpenMP and optimisation flags as the cp312 binary.
|
|
- Pre-compiled Windows AMD64 binaries for **CPython 3.10, 3.11, 3.13**
|
|
(`sem_core12.cp3{10,11,13}-win_amd64.pyd`). Built with MSVC v14.50
|
|
against the matching CPython installed via `winget`.
|
|
|
|
### Verified
|
|
|
|
- All eight binaries (4 Linux + 4 Windows) produce identical numerical
|
|
output for the same fixed-seed input on `batch_max_similarity`.
|
|
|
|
### Compatibility notes
|
|
|
|
- macOS is still not provided in this release. Contact
|
|
`sales@sevana.biz` if you need a macOS build.
|
|
- numpy requirement unchanged: `numpy >= 1.23`.
|
|
|
|
## [1.0.0] - 2026-05-09
|
|
|
|
First public release.
|
|
|
|
### Included
|
|
|
|
- Pre-compiled Linux x86_64 binary (`sem_core12.cpython-312-x86_64-linux-gnu.so`)
|
|
built with gcc 13.3, OpenMP-parallel (`libgomp`), `-O3 -ffast-math
|
|
-march=native`.
|
|
- Pre-compiled Windows AMD64 binary (`sem_core12.cp312-win_amd64.pyd`)
|
|
built with MSVC v14.50 (Visual Studio Build Tools 2026),
|
|
OpenMP-parallel (`vcomp`), `/O2 /openmp`.
|
|
- Python wrapper module `sem_cython12.wrapper` exposing the public
|
|
numerical API.
|
|
- Single runtime dependency: `numpy >= 1.23`.
|
|
|
|
### API surface
|
|
|
|
Configuration:
|
|
- `available()`, `backend()`, `get_num_threads()`, `set_num_threads(n)`.
|
|
|
|
Distance and similarity:
|
|
- `batch_max_similarity(X_query, X_members, lam)`
|
|
- `concept_support_matrix(X_query, member_mats, lam)`
|
|
- `pairwise_distances(X)`
|
|
- `nn_distances(X)`
|
|
|
|
Best-tradeoff filtering:
|
|
- `pareto_core_mask(S)`
|
|
- `one_sided_mask(S)`
|
|
- `non_redundant_witnesses(S)`
|
|
|
|
Vector reduction:
|
|
- `extend_frontier_kernel(cur_centers, cur_radii, new_emb, cur_arity)`
|
|
|
|
### Compatibility
|
|
|
|
- CPython 3.12 (cp312) only in this release. Other Python versions
|
|
are not supported.
|
|
- Linux x86_64 with glibc 2.31 or newer (Ubuntu 20.04 LTS and later,
|
|
RHEL 9 and later, Debian 11 and later).
|
|
- Windows 10 / Windows 11 / Windows Server 2019+, AMD64 only.
|
|
- macOS binaries are not provided in this release. Contact
|
|
`sales@sevana.biz` if you need a macOS build.
|
|
|
|
### Notes
|
|
|
|
- Thread count defaults to roughly 50% of the host's logical cores.
|
|
Override via `sem_cython12.wrapper.set_num_threads(n)` or the
|
|
`SEM_NUM_THREADS` environment variable.
|
|
- The library performs no network I/O, opens no sockets, and writes
|
|
no files outside the calling process's working directory.
