This one probably won't touch you visibly so just bookmark @​webknjaz's EuroPython 2026 “AI” slop rant for when it's published on YouTube or encourage him to come back with more to share next year!

🛠️ Urgh… Another release!? Again? Explain yourself!

Looking at the diff, you'll only witness updates across the dependency tree. That's it! It's not a security fix or anything like that even, no. But you'll want this update.

[!tip]
So what most people will find useful is @​takluyver💰's update of Twine to v7 that we use internally (#​416). This version will let them upload their sdists and wheels containing core packaging metadata v2.5 to (Test)PyPI.

🧐 Tell me why..

The rest of the updates bump things related to pypi-attestations and sigstore, which has the most interesting backstory here. @​facutuesca💰 sent a patch in #​417 but a bunch more helped out.

TL;DR non-pure-python projects with C-extensions tend to have dozens (sometimes hundreds) wheels to upload to PyPI per release. They are often quite big and take time to transfer over the network. People started noticing problems and coming up with DIY sharding workarounds like aio-libs/aiohttp#13226 around July 23.
On this date, projects with a good amount of bytes to publish would start getting timeouts 5 minutes after the PyPI publishing job begun. The same job that worked just fine before.

I had to start pinging upstream library and ecosystem people, on GitHub and privately, to start making sense of what was happening. Eventually, we collectively concluded that GitHub must've shortened the lifetime of their OIDC identity — it seems to have used to be 10 minutes long (at some point in the past) and is now 5 minutes, apparently. It's not documented clearly, and we have not been able to get any clarity by attempting to contact GitHub through private channels, using personal connections.

Over the course of investigation, @​facutuesca💰 found and fixed a related underlying cache invalidation bug in sigstore/sigstore-python#1838, which he then coordinated propagation through the dependency chain updates in sigstore-python, pypi-attestations, gh-action-pypi-publish and gh-action-sigstore-python.

Mike's also discovered that Sigstore's Rekor slowdown seems to have become the main contributing cause of the last week's incident. He's collected some data to support this claim: https://publishing-five-minute-timeout.tiiny.site.

🙏 Special Thanks to @​davidbrochart💰 and @​Dreamsorcerer💰 for turning my attention (in #​415 and in private) to the newly surfaced corner case in GitHub's behavior that only affected a narrow category of projects while many others remained blissfully unaware. @​bdraco💰 came up with a DIY sharding workaround for aiohttp that served as a demo for other projects. @​miketheman💰 confirmed the Warehouse-side details. Also, @​jku💰 and @​woodruffw💰 helped work through, review and release the Sigstore ecosystem upstream libs.

This release was cut at EuroPython 2026 Sprints

🛠️ Internal Dependencies

Audit your supply chain regularly!

✨ What's Changed

The main change in this release is that verbose and print-hash inputs are now on by default. This was contributed by @​whitequark💰 in #​397.

📝 Docs

@​woodruffw💰 updated the mentions of PEP 740 to stop implying that it might be experimental (it hasn't been for quite a while!) in #​388 and @​him2him2💰 brushed up some grammar in the README and SECURITY docs via #​395.

🛠️ Internal Updates

@​woodruffw💰 bumped sigstore and pypi-attestations in the lock file (#​391) and @​webknjaz💰 added infra for using type annotations in the project (#​381).

Take the 2025 Python Packaging Survey if you still haven't!

[!important]
🚨 This release includes fixes for GHSA-vxmw-7h4f-hqxh discovered by @​woodruffw💰.
We've also integrated Zizmor to catch similar issues in the future and you should too.

✨ New Stuff

@​woodruffw💰 updated the README to no longer mention the attestations feature being experimental in #​347: it's been rather stable for a year already 🎉
He also added more diagnostic output which includes printing out the GitHub Environment claim via #​371 and warning about the unsupported reusable workflows configurations #​306, when using Trusted Publishing.

[!tip]
The official support for reusable workflows is currently blocked on changes to PyPI. To get updates about progress on the action side, you may want to subscribe to #​166.
At PyCon US 2025 Sprints, @​facutuesca💰, @​miketheman💰, @​woodruffw💰 and I💰 spent several hours IRL brainstorming how to fix this and migrate projects that happen to rely on an obscure corner case with reusable workflows that temporarily allows them to function by accident.
The result of that discussion is posted @​ pypi/warehouse#11096 (comment).
Note that this is a volunteer-led effort and there is no ETA. If you need this soon, make your employer sponsor the PSF and maybe they'll be able to hire somebody for this work on Warehouse.

In addition to that, @​konstin💰 sent #​378 to pin actions/setup-python to a SHA hash. This makes pypi-publish compatible with new GitHub policies that allow organizations to mandate hash-pinning actions used in workflows.

🛠️ Internal Dependencies

@​webknjaz💰 made a bunch of updates to the action runtime which includes bumping it to Python 3.13 in #​331 and updating the dependency tree across the board. pip-with-requires-python is no longer being installed (#​332). Some related bumps were contributed by @​woodruffw💰 (#​359) and @​kurtmckee💰 sent a contributor-facing PR, bumping the linting configuration via #​335.
