Add official support for Python 3.14 (released October 7, 2025). Changes: - Add Python 3.14 classifier to pyproject.toml - Add py314 to tox envlist and gh-actions mapping - Add 3.14 to test matrix in GitHub Actions Python 3.14 includes major features: - Free-threaded Python official support (PEP 779) - Deferred evaluation of annotations (PEP 649) - Template string literals (PEP 750) - Experimental JIT compiler Note: setup-uv (v5) has Tier 1 support for Python 3.14, so no additional workarounds should be needed (unlike Python 3.13). Will monitor CI results to confirm. Closes #615 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Add the same workaround used for Python 3.13 to Python 3.14 to avoid build failures with missing Python.h headers. This workaround uses actions/setup-python@v5 in addition to setup-uv for Python 3.14 to ensure proper Python development headers are available.

Closing this PR as PyArrow does not yet provide Python 3.14 compatible wheels, which causes build failures when trying to compile from source. We'll wait for PyArrow to officially support Python 3.14 before adding support to PyAthena. See: https://status.fedoralovespython.org/wheels/ |

Correction: The correct PyArrow Python 3.14 support issue is:
PyArrow team aims to provide full Python 3.14 support in the PyArrow 22 release. |

Python 3.14 includes several significant improvements:
Testing Notes
No workaround needed: Unlike Python 3.13, Python 3.14 should work directly with
setup-uv@v5which has Tier 1 support for Python 3.14. The existing Python 3.13 workaround (usingsetup-python) is kept as-is for now.If CI passes successfully without needing the workaround for Python 3.14, we can potentially remove the Python 3.13 workaround in a future PR.
