Modernize Python support and CI for Python 3.14#67
Merged
Conversation
Update minimum Python version from 3.9 to 3.12 and PyYAML from >=5.4 to ^6.0.1 (5.x does not support Python 3.14). Modernize CI workflow: - Replace hardcoded Python version matrix with org-level ARCALOT_PYTHON_SUPPORTED_VERSIONS variable - Replace hardcoded '3.9' conditionals with ARCALOT_PYTHON_VERSION - Use ARCALOT_POETRY_VERSION org variable for Poetry installation - Update GitHub Actions: checkout v3->v4, setup-python v4->v5, upload-artifact v3->v4, download-artifact v3->v4 - Add version suffixes to artifact names (required by upload-artifact v4 with matrix builds) - Update runner to ubuntu-24.04 Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
