v1.1.1

Full Changelog: v1.1.0...v1.1.1

v1.1.0

Coproduct-compatible R-matrix APIs, exact integer/q-arithmetic handling (Laurent-polynomial formulas, no removable singularities), input validation, cross-platform CI (Linux/macOS/Windows, Python 3.10-3.13), 202 tests (198 + 4 doctests). Full mathematical/technical audit with corrections to the R-matrix/coproduct convention, the Celik & Celik (2021) bibliography page range, and the AI-usage disclosure (see AUDIT.md and thesis/ERRATA.md). Prepared for submission to the Journal of Open Research Software (see jors/).

1.0.0 - 2026-09-27

First release, prepared for submission to the Journal of Open Source Software.

Added

• MIT LICENSE.
• pyproject.toml: the package installs as quantum-group with
  pip install -e .; test and notebook dependencies are the optional extras
  [test] and [notebooks].
• GitHub Actions workflow running pytest on Python 3.10, 3.11 and 3.12.
• CONTRIBUTING.md and CITATION.cff.
• benchmarks/benchmark.py with recorded timings (benchmarks/results.md,
  benchmarks/results.csv) for the GL_q(2|1) checks up to 243x243 matrices.
• README sections "Mathematical Background" (derivation of the
  U_q(sl_2) R-matrix and its coproduct convention) and "Related Work"
  (comparison with GAP QuaGroup and SageMath).
• Derivation, convention note and references in the R_matrix_V1 docstring.
• JOSS paper draft: paper/paper.md and paper/paper.bib.

Changed

• jones_skein_relation_check renamed to hecke_skein_relation_check. The
  function verifies the Hecke relation, not a Jones polynomial.
• README performance notes now quote measured timings.
• requirements.txt now installs the package itself (-e .[test,notebooks]).

Deprecated

• jones_skein_relation_check: still available, but emits a
  DeprecationWarning. Use hecke_skein_relation_check.

Removed

• poster/node_modules/ is no longer tracked by git.

Pre-1.0 development (April-June 2026)

Initial implementation developed for the undergraduate thesis Quantum Grup
Yapılarının Python Ortamında Modellenmesi:

• U_q(sl_2) representations, relations, Hopf structure, tensor products
  and R-matrix checks;
• GL_q(2|1) graded Yang-Baxter verification;
• limits, crystal graphs and visualization;
• the pytest suite.
