PyPI Announces Policy to Reject New Files After 14‑Day Release Window

The Python Package Index (PyPI) has updated its upload policy. Releases will no longer accept new files after a fourteen‑day period. The change aims to improve package stability and security. Maintainers must finalize all assets within the initial two weeks. Files submitted later will be automatically rejected. The policy was announced on the PyPI blog on July 22, 2026. Developers are advised to review their release schedules. Existing packages are unaffected unless updated after the deadline. PyPI expects the rule to reduce supply‑chain risks. Community feedback will be monitored for further adjustments.
