Somewhat interesting that "volunteer project no longer under active development" got changed to "unmaintained".

For context, they have 2 to 4 commits per month since October [1]. The last release was July 2025 [2]. [1]: https://github.com/pypy/pypy/commits/main/ [2]: https://github.com/pypy/pypy/tags

That seems reasonably active to me. You can't really expect more from an open source project without paid full-time developers.

Odd how you still see announcements of this nature if Anthropic's marketing is be believed.

Yup. For me the biggest signifier is Spotify. They claim their (best) devs don't even code anymore, they use an internal AI tool that they just send prompts to which then checks out a personal test build that they can download off of Slack. "A new feature in 10 minutes!" Okay, if that is the case, why have we only seen like 3-4 minor new QoL improvements in Spotify the last ~12 months, with no new grand features? And…

Everyone here says "if developers are so much faster, why aren't we seeing more features?!" as if the only thing required to release a feature is developers.

My CEO keeps asking me "how can we go faster with AI", and my answer is "we can't, because even if we had developers that would instantly develop any feature perfectly, we'd still be bottlenecked on how slow we are at deciding what to actually release".

I don't know about that. For me, f-strings were the last great quality-of-life improvement that I wouldn't want to live without, and those landed in Python 3.6. Everything after that has not really made much of a difference to me.

That's like saying the last tax that affected you was passed in 2006...

I don't understand. Could you elaborate?

What annoys me is the name. Early morning it took me a moment to realise that PyPy is not PyPi, so at first I thought they referred to PyPi. Really, just for the name confusion alone, one of those two should have to go. Edit: I understand the underlying issue and the PyPy developer's opinion. I don't disagree on that part; I only refer to the name similarity as a problem.

There is no PyPi, it's PyPI (py pee eye), the Python package index.

PyPy is a fantastic achievement and deserves far more support than it gets. Microsoft’s “Faster CPython” team tried to make Python 5x faster but only achieved ~1.5x in four years - meanwhile PyPy has been running at over 5x faster for decades. On the other hand, I always got the impression that the main goal of PyPy is to be a research project (on meta-tracing, STM etc) rather than a replacement for CPython in produc…

We have been using PyPy on core system component on production for like 10 years

tbf they have been saying they've started doing this since December, so we're only a few months in. And like most software it's an iceberg: 99% of work on not observable by users, and in spotify's case listeners are only one of presumably dozens of different users. For all we know they are shipping massive improvements to eg billing

Anthropic released vibe coded C compiler that doesn't work, how their LLM can help in maintaining PyPy?

Strikes me as the worst possible solution if they're struggling to find maintainers in the first place. Who reviews the vibe coded patches?

If anyone else is also barely aware and confused by the similar names, PyPI is the Python Package Index, which is up and maintained. PyPy is "A fast, compliant alternative implementation of Python." which doesn't have enough devs to release a version for 3.12[0]. [0]: https://github.com/orgs/pypy/discussions/5145

and mypy is "an optional static type checker for Python" [0] Given that both pypy (through RPython) and mypy deal with static type checks in some sense, I kept confusing the two projects until recently. Also, I just learnt (from another comment in this post) about mypyc [1], which seems to complete the circle somehow in my mind. [0] https://www.mypy-lang.org/ [1] https://github.com/mypyc/mypyc

pypy existed long before type annotations were a thing

Also, why isn‘t there a native client for all platforms? Could they not just let the AI auto-translate the code?

much respect to the PyPy contributors, but it seems like a pretty fair assessment

9 months since the last major release definitely feels like a short time in which to declare time-of-death on an open source project

But if you set up dependabot and automerge some crap every couple of days your project will be very active!

Meanwhile my projects got marked as abandoned because those scanners are unaware of codeberg being a thing.
