Python 3.13 beta 3 is out, so I snagged a copy of the source and built my own executable:

Not much to report from the last time I built beta 2, but for my own memory here’s how I configured it before I built it.

../Python-3.13.0b3/configure --enable-optimizations --disable-gil --enable-experimental-jit

I have yet to try out either GIL-less testing (which would require I come up with some sort of concurrency test) as well as how having a JIT in Python might help things along, although I am working on some non-trivial performance testing between 3.12.4 and 3.13 beta.
