Announcing PHEP 3
PyHC has formally adopted PHEP 3: PyHC Python & Upstream Package Support Policy! This new PHEP establishes a unified, time-based approach to dependency support across the PyHC ecosystem, bringing our community into alignment with the broader Scientific Python ecosystem.
PHEP 3 recommends that all PyHC packages adopt the following support policy, based on SPEC 0:
- Support Python versions for 36 months (3 years) after their initial release
- Support core Scientific Python packages for 24 months (2 years) after their initial release
- Adopt new versions within 6 months of their release
This policy applies to Python itself and to the upstream core Scientific Python packages: NumPy, SciPy, Matplotlib, pandas, scikit-image, NetworkX, scikit-learn, xarray, IPython, and Zarr.
To learn more, read the full PHEP 3 document. We will also maintain a PHEP 3 Support Schedule page with a graphical timeline and quarterly reminders to help package maintainers stay on track. Questions or feedback? Join the discussion on PyHC’s mailing list or Slack!
