As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html
This is most likely the last beta of this series so if you want something merged now is a good time to get it ready ;-)

By the way, shouldn't this option be default, at least for development purposes?
It's annoying to type it all the time.

I am not personally working on getting it ready, but I strongly believe that no release should happen until
is resolved - while it does not affect doctests, it hugely affects live usage.

FWIW, on Debian testing running on core i7 + 16 GB RAM, upgrading from 9.2.beta9 + ptestlong gives me the same permanent failures obtained since 9.2.beta5.

After incremental build from 9.2.beta9, I'm having troubles with 9.2.beta10 running doctests on macOS 10.15.6.
I can do ./sage -t src/sage/graphs/orientations.py
but ./sage -t src/sage/graphs/graph.py never ends :(
I can try make dist-clean if we have no other solution...
