No `cp313` or `cp314` wheels exist. - **Broken sdist build**: The source distribution depends on the deleted GitHub repo `ozgrakkurt/dict-derive`, so `pip install` from source fails with a 404. - **PyO3 version too old**: hypersync 0.8.5 uses PyO3 0.20, which only supports Python up to 3.12. Python 3.13 needs PyO3 0.22+, and Python 3.14 needs PyO3 0.26+. - **Upstream unreleased fixes**: The hypersync main branch has upgraded to PyO3 0.22 (supporting 3.13) but this has not been released to PyPI yet. Python 3.14 support (PyO3 0.26+) is not on the roadmap. ### Related upstream issues - [enviodev/hypersync-client-python#43](enviodev/hypersync-client-python#43) — `pip install fails - dict-derive returns 404` - [enviodev/hypersync-client-python#46](enviodev/hypersync-client-python#46) — `installation failed due PEP517 build of a dependency failed` - [enviodev/hypersync-client-python#45](enviodev/hypersync-client-python#45) — `Python client logs are not capturable via Python logging` ## Changes | File | Change | |------|--------| | `Dockerfile.vault-scanner` | Python 3.11 → 3.12 (+ comment re: hypersync) | | `Dockerfile.analysis-vault` | Python 3.11 → 3.12 (+ comment re: hypersync) | | `.readthedocs.yml` | Python 3.11 → 3.12 | | `scripts/erc-4626/scan-vaults-all-chains.py` | Fix `datetime.utcnow()` | | `scripts/hypersync/robustness-manual-check.py` | Fix `datetime.utcnow()` | | `contracts/terms-of-service/tests/test_sign_terms_of_service.py` | Fix `datetime.utcnow()` (4 occurrences) | | `CHANGELOG.md` | Add upgrade entry | 🤖 Generated with [Claude Code](https://claude.com/claude-code)
