PyPy maintenance status is now explicitly flagged in astral-sh/uv's documentation after a pull request (PR #17643) added a warning about the Python interpreter's lack of active development.

This update follows reports that PyPy is no longer being actively developed, even by numpy itself (numpy/numpy#30416). While the PyPy project hasn't issued an official statement, the numpy issue was reportedly created by a PyPy developer, signaling potential broader ecosystem impacts.

The PR, co-authored by Tomasz Kramkowski, modifies the astral-sh/uv documentation to caution users against assuming PyPy is a properly supported and maintained Python distribution. This move aims to prevent confusion among developers relying on the tool for critical projects.

Question: Does this mean PyPy is completely abandoned?

Answer: While the astral-sh/uv documentation now warns against assuming PyPy's active maintenance, the PyPy project itself hasn't formally declared abandonment. The warning reflects growing concerns within the Python ecosystem about the project's future viability and support levels, particularly for newer projects like astral-sh/uv.
