Thanks for this new release!

On macOS 10.14.6 with many Homebrew packages installed,

starting from a working previous beta release,

Sage 9.4.beta6 builds and passes all but one doctests.

```

$ git pull origin develop --tags -q && git branch -v

Here is the test failure:

Possibly related to Singular, if it is the same failure as in

https://trac.sagemath.org/ticket/31623

I will try rebasing #32001 on Sage 9.4.beta6 to see

if upgrading to Singular 4.2.1 solves this problem.

On my Mac OS 11.5, it compiled from the first built. But for ptestlong, it failed….

8bae3ff7ad (tag: 9.4.beta6, trac/develop) Updated SageMath version to 9.4.beta6

Update from GH Actions at https://github.com/sagemath/sage/actions/runs/1062866951:

fedora-34-minimal: is clean now

-standard: times out during build, but looks clean to this point

fedora-35 fails in the bootstrapping phase with "/usr/bin/m4: m4_esyscmd subprocess failed: Operation not permitted"

- this is likely just an intermittent problem in Fedora Rawhide (unstable)

Update from GH Actions at https://github.com/sagemath/sage/actions/runs/1062866950:

cygwin: Thanks to Trac #32257 (Cygwin patch for Singular), building on cygwin succeeds, including the docbuild.

Numerous doctest failures (https://github.com/sagemath/sage/runs/3157309933?check_suite_focus=true)

1) due to unexpected messages "UserWarning: Attempting to work in a virtualenv. If you encounter problems, please install IPython inside the virtualenv."

2) Various problems with gap: "Gap produced error output" in src/sage/libs/gap/element.pyx, src/sage/interfaces/gap.py

3) Timeouts in src/sage/geometry/polyhedron/base.py, src/sage/geometry/polyhedron/library.py, src/sage/parallel/map_reduce.py

4) Some numerics-related doctest failures in src/sage/symbolic/expression.pyx,

Overall, this looks "good enough for a source release". Issue https://trac.sagemath.org/ticket/31565 (Build still non-portable despite SAGE_FAT_BINARY=yes because of numpy) is still unresolved at least for Cygwin, and would block us from making binary releases on Cygwin. But currently no one is making binary releases for Cygwin anyway. So I have reduced this ticket from blocker to "critical".

Yes, I've seen it too in recent runs on this platform. I'm hoping that this is just a temporary problem from some kernel / glibc / docker mismatch and will just go away by itself...
