Warn about PyPy being unmaintained

296 points by networked a month ago on hackernews | 160 comments

It seems that PyPy is not being actively developed anymore and is phased out even by numpy (numpy/numpy#30416). There's no official statement from the project, but the numpy issue is from a PyPy developer. I added a warning to avoid users assuming PyPy properly supported and developed Python distribution.
