There's no mention of what Python version this is actually in.

After some digging, it looks like the answer is 3.14 [0], so we won't be seeing this until October [1].

One could argue that this is a security fix (just read the first sentence of the blog post) and should be included in all the currently supported versions (>=3.9) of Python [2].

Many famous libraries like Spacy do not support Python 3.13 and are stuck on Python 3.12 (Oct 2023).

So, even if this comes out in Python 3.14, any non-trivial project will have to wait till Oct 2026 (or Oct 2027) to be able to use it.

Good grief that issue is a clusterfuck of bozos.

Sometimes I wish there was a GitHub with entry exam. "A library you use has a bug, you find a find a 3 month old bug report for your exact issue. Do you 1) add a comment with "me too", 2) express your frustration this issue hasn't been fixed yet, 3) demand the maintainers fix it as soon as possible as it's causing issues for you, or 4) do nothing".

Only half joking.

I have been getting paid to write Python since the late 90s and it amazes me how it consistently has these needless own goals, yet still keeps on going in spite of itself. Way to go Python!

spaCy should make Cython optional

hard fork Cython to not used stringitized annotations

stay on Python 3.12 forever and then skip to 3.15

It is like have a crowd of people trying to outdo each other on how much self harm they can induce.

I hit this when upgrading to Ubuntu 25.04 as that upgraded to Python 3.13. I'm running the various python projects I want in a venv. For the projects stuck on 3.12 I ended up building and installing it from source to my local directory (removing the unprefixed links for compatibility) as the ppa for Python ports doesn't (didn't?) support the latest Ubuntu.

I dislike using something like docker or conda as I don't want to install/use a separate distro just to be able to use a different version of Python. My setup is working well so far.

I was going to write something glib about getting things fixed but that thread looks gnarly!

To be honest I know so many people who use Pydantic and so many people who seem to get stuck because of Pydantic 2. I’m glad I have minimal exposure to that lib, personally.

I suppose the biggest issue really is type annotation usage by libs being intractable

Does that mean that a point release of Python has breaking changes? If true, that sounds crazy.

Just ran into something similar with Great Expectations. Python 3.12 is the newest I can run.

How?

From https://github.com/python/cpython/issues/99108#issue-1436673...:

> As evidenced by the recent SHA3 buffer overflow, cryptographic primitives are tricky to implement correctly. There might be issues with memory management, exceeding lengths, incorrect buffer management, or worse, incorrect implementations in corner cases.

This is a proactive fix for zero days that may be lurking in the wild.
