Sage 9.6.beta4 released

[Volker Braun]

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

1e8ba0aac4 (tag: 9.6.beta3) Updated SageMath version to 9.6.beta3

[Emmanuel Charpentier]

FWIW, on Debian testing running on core i7 + 16 GB RAM, upgrading 9.6.beta3 to 9.6.beta4 gines me one transient failure (already known) :

sage -t --long --warn-long 209.2 --random-seed=31897748386618397374885466269378290605 src/sage/schemes/cyclic_covers/cycliccover_finite_field.py  # 1 doctest failed

and one permanent one (new to me):

Pytest is not installed, skip checking tests that rely on it.

I can’t formally check it now, but the “failure” seems to be bound only to the … Sage version number in the initial comment. Therefore a cosmetic booboo, but not so easy to fix…
