Python 3.13 release

[cbenz]

I'd like to be able to use the latest release of cysimdjson (24.12) with Python 3.13, using a wheel to avoid recompiling it myself.

It seems it's not possible:

$ python --version
Python 3.13.0

$ pip install cysimdjson==24.12
ERROR: Could not find a version that satisfies the requirement cysimdjson==24.12 (from versions: 21.11b2, 21.11, 23.7, 23.8)
ERROR: No matching distribution found for cysimdjson==24.12

I can install the previous version (23.8) by relaxing the constraint (but I want the latest!), by compiling the wheel:

$ pip install cysimdjson

It seems that the source distribution was omitted in the latest release (24.12).

Would it be possible to publish wheels for Python 3.13 for the latest release (24.12)?

Solved by doing

pip install git+https://github.com/TeskaLabs/cysimdjson

@cbenz, despite getting the package from GitHub enables installing, calling loads yields

Process finished with exit code 132 (interrupted by signal 4:SIGILL)

Can you confirm it?

My setup is

Python 3.13.2 (main, Feb  5 2025, 08:05:21) [GCC 14.2.1 20250128] on linux

@StSav012 No, I don't have that error:

Could you provide a reproducible example?

[StSav012]

Sure.
