Today is Volunteer Responsibility Amnesty Day
"Volunteer Responsibility Amnesty Day is about checking with yourself, and ending the commitments you need to end – maybe by taking a break, or by rotating it on to someone else, or by sunsetting a project."

I've updated the https://www.python.org/downloads/ page:
Added download links to the active Python versions table. Before, you had to hunt for the one you wanted in the table below.
They're redirect links, so, for example, https://www.python.org/downloads/latest/python3.15/ goes to https://www.python.org/downloads/release/python-3150a2/ and https://www.python.org/downloads/latest/python3.13/ goes to https://www.python.org/downloads/release/python-3139/
Could be handy for your docs, if you want to point people to the latest, say, 3.12.

Those snakes are from the Hiekka Art Museum, as was this typewriter with separate uppercase and lowercase keys, and art deco furniture by Eliel Saarinen and Armas Lindgren.
Also went to the Tampere Art Museum, didn't take photos but the Man Yau exhibition was good.

The Windows build has been started.
The jobs with profile-guided optimisation (PGO) build once, then collect a profile by running the tests, and then build again using that profile, to see how "real" code executes and optimises for that.
https://dev.azure.com/Python/cpython/_build/results?buildId=164907&view=results
Meanwhile, the docs+source+Android build has finished and the artifacts have been copied to where they need to go with SBOMs created.

(That's actually the second CI attempt, we had to update some script arguments following an Android test runner update.)
This build takes about half an hour.
I've also informed the Windows and macOS release managers about the tag and they will start up installer builds.
This takes a few hours, so I've got time to finish up the release notes.
PEP 101 is the full process, but much is automated and we don't need to follow it all manually.

Next up, merge and backport the final change to What's New in Python 3.14 to declare it latest stable.
https://github.com/python/cpython/pull/139631
Now start run_release.py, the main release automation script, which does a bunch of pre-checks, runs blurb to create a merged changelog, bumps some numbers, and pushes a branch and tag to my fork. It'll go upstream at the end of a successful build.
Then kick off the CI to build source zips, docs and Android binaries.

Release day!
First off, check blockers and buildbots.
A new release-blocker appeared yesterday (because of course) but it can wait until 3.14.1.
https://github.com/python/cpython/labels/release-blocker
Three deferred-blockers are also waiting until 3.14.1.
https://github.com/python/cpython/labels/deferred-blocker
A new tier-2 buildbot failure appeared yesterday (because of course) but it had previously been offline for a month and will need some reconfiguration. Can ignore.

Three days until release and a bug in the Linux kernel has turned a dozen buildbots red...
It's already been fixed in the kernel, but will take some time to bubble up. We'll skip that test for relevant kernel versions in the meantime.

Helsinki airport tips:
If getting the I train from the city, get on the last carriage to optimise exit (I think second from last doors are usually best).
Take the first escalator up from the platform, then after the short tunnel walk, take the lift as it's faster than the big escalators.
The Alepa grocery store before security has lots of sandwiches and pastries.
Turn left immediately after security for a water tap to fill your empty bottle.

Python 3.14:
We'll make the next release candidate (rc2) this Thursday, two weeks early, and add a rc3 on 2025-09-16.
We fixed a code generation bug that required the "magic number" to be increased for rc2. This means .pyc files compiled by rc1 can't be used in rc2 and will be recompiled.
The ABI isn't changing, and wheels built for rc1 should still work for rc2, rc3 and 3.14.x, but it's better to get this out for testing sooner.

Upcoming change to GitHub Actions: macos-latest will move from the macOS 14 image to macOS 15.
There's a slight change in tooling, if stuff fails, you can pin to macos-14.
More interestingly, the macos-13 image will be retired between 1st September and 14th November.
Notably, macos-13 is Intel, and macos-14 and 15 are Apple silicon.

Well, that took a while, partly because the RC is the first time the docs are included in the release.
The plain text build failed due to some Sphinx csv-table bug, needing a quick docs rewrite to use list-table (thanks, Adam Turner!) and a fresh start.
This actually broke back in April but we didn't notice. More CI needed!
Enjoy the plain text docs!

GitHub Actions now supports free-threaded Python!
I wrote up how to add it your workflows so you can start testing free-threaded Python 3.13 and 3.14 with either actions/setup-python or actions/setup-uv.

Full front page page ad (it's always an ad) by Kia on Helsingin Sanomat, Finland's largest subscription paper, translates something like:
"Voi näita Elon päiviä"
"Oh these days of living"
(elon = of living)
"Jos amerikkalaisella sähköpelillä ajelu mietityttää, niin tervetuloa Helsingin Messukeskukseen ihastelemaan uuden ajan autoja."
"If driving an American electric vehicle troubles you, then welcome to Helsinki Convention Centre to admire modern cars."
(corrections welcome!)

The #Python #typing spec and docs have now been given their own subdomain:
https://typing.python.org
The old links will redirect, but please update your links to the canonical ones. Thanks to Sebastian Rittau for getting this done.
