Python 3.12 not supported

[nicolargo]

On my fresh Ubuntu 24.04 install:

sudo env "PATH=$PATH" ./venv-dev/bin/py-spy record --pid 66778
Error: Unsupported version of Python: 3.12.0

Is it plan to support Python 3.12 ?

Probably not very helpful, but https://github.com/plasma-umass/scalene and pyinstrument (both sampling profilers) support python 3.12 now. Maybe possible to get hints of how to resolve some of the issues there.

https://github.com/joerick/pyinstrument/pull/246

Couldn't find the exact commits/PR for scalene

EDIT: https://github.com/P403n1x87/austin support 3.12 as well (this seems to be the best replacement to me since its model appear to be very similar to py-spy)
