Thanks for the release. I have a couple of issues. There are several places, like pyproject.toml where python version is set <3.14. Changing it <3.15, it builds with python 3.14 in Fedora 43. The other issue is more strange because it happens in one computer with F43 but not in other one when building the documentation. I get :

```

 Some ideas? Best, Enrique.

[Dima Pasechnik]

For this release we're too late with Python 3.14. On Fedora 43 you can
install python3.13-dev and use it to build Sage, no?

There is a problem with this, see https://github.com/sagemath/sage/issues/41258 (blocker)

if you have python3=python3.14, it's currently not possible to force python3.13 or python3.12

[Enrique Artal]

Which is the problem? Changing <3.14 by <3.15 in several places, I got it built.

[Dima Pasechnik]

you have it built, but have you run tests? on my Intel macOS every test  fails with an error pointing to an atexit problem if I use Python 3.14.
