The PSF Board has approved the latest revision of PEP 772, modulo a small change to the Conflict of Interest section. It now reads:
The Python Steering Council is the final arbiter for technical conflicts of interest, and the Python Software Foundation Board is the final arbiter for conflicts of interest related to governance for the Packaging Council.
With this, the PEP moves on to PyPA approval. @pradyunsg to drive that step.
