[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.
