fastparquet 2024.11.0 depends on cramjam 2.9.1, which doesn't support Python 3.14. While cramjam 2.11.0 added Python 3.14 support, fastparquet hasn't released a version using it yet. Since fastparquet is only used in dev dependencies (not core PyAthena functionality), exclude it for Python 3.14 until fastparquet releases Python 3.14 compatible wheels. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
For Python 3.13 and 3.14, older versions of numpy and pandas don't have pre-built wheel files, causing slow source builds during installation. Changes: - numpy: Use >=2.3.0 for Python 3.13+ (has wheels for cp313/cp314) - pandas: Use >=2.3.0 for Python 3.13+ (has wheels for cp313/cp314) - Keep older minimum versions for Python 3.10-3.12 for compatibility This ensures fast installation with binary wheels on all supported Python versions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
