Sage 9.4 released

[Volker Braun]

The "master" git branch has been updated to Sage-9.5. 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

There was no change over 9.4.rc2

488ced5dc4 (tag: 9.4, trac/master, trac/develop) Updated SageMath version to 9.4

7282b2b6c6 (tag: 9.4.rc2) Updated SageMath version to 9.4.rc2

There was a version 9.5 visible for a short while since I got myself confused by the (incorrect) 9.4 tag, this is fixed now. But if you were real quick in downloading it then you can delete it now %-)

This confusion 9.4 / 9.5 is breaking badly the patchbot server. I had to fix things by hands once, and need now to fix them again :(

It also broke pushing the documentation online,
in the sense that we now have online documentation
pretending to be the Sage 9.4 documentation while
really being identical to the Sage 9.3 documentation.
Hopefully this can be solved soon.

Regarding producing the binaries, I opened an issue
at binary-pkg to support older processors:

https://github.com/sagemath/binary-pkg/issues/31

but a pull request is still missing, help welcome.

All that being said, thanks a lot to all the contributors
and to the release manager for this new release,
I'm very happy about the improvements it brings.

Please remember to enrich the release tour

https://wiki.sagemath.org/ReleaseTours/sage-9.4

with the novelties you find exciting and wish to share
(that applies to me too!). --Samuel

Built and tested on three macOS platforms. All builds completed without problems. Testing (‘ptestlong’) went as follows:

10.13.6 (2017 iMac Pro, 18-core Xeon W): One failure
sage -t --long --warn-long 69.2 --random-seed=0 src/sage/geometry/polyhedron/base.py
[the usual flakey “get_memory_usage()” test]

10.14.6 (2017 MBP, 4-core Core i7): Two failures
sage -t --long --warn-long 135.2 --random-seed=0 src/sage/graphs/bipartite_graph.py
[usual intermittent “expected 0.0, got something different” failure]
sage -t --long --warn-long 135.2 --random-seed=0 src/sage/symbolic/integration/external.py
[this one seems persistent: two exceptions following a “KeyError: sageVAR”]

10.15.7 (2019 MBP, 8-core Core i9): One failure
sage -t --long --warn-long 135.2 --random-seed=0 src/sage/graphs/bipartite_graph.py
[usual intermittent “expected 0.0, got something different” failure]

Almost the same as 9.4.rc2 :-}

In particular, now that the Sage 9.4 documentation is up (https://doc.sagemath.org/html/en/reference/index.html), we can add links to the new functionality. 

I have done this already in some of the sections.

On my mac OS 11.5.2, it compiled from the first built. But with make ptestlong, it failed :

sage -t --long --random-seed=0 src/sage/geometry/polyhedron/base.py  # 1 doctest failed

sage -t --long --random-seed=0 src/sage/misc/gperftools.py  # 1 doctest failed

Just last year Intel came out with a (cheaper Pentium-branded) CPU that still doesn't support AVX, so its really not just old CPUs....

----------------------------------------------------------------------

sage -t --long --warn-long 356.4 --random-seed=0 src/sage/calculus/riemann.pyx  # Killed due to segmentation fault

Total time for all tests: 19434.6 seconds

    cpu time: 61444.5 seconds

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

make: *** [Makefile:201: ptestlong] Error 16

Only one failure in ptestlong on 64 bit Raspberry Pi OS!

Cheers,

this is very good! What happens if you try this is with various
optional packages installed, as well?
(such as e.g. gap_packages)

It is not perfectly clear to me, what you want me to do. What packages should I install?

Something like: ./sage -i gap_packages

Notice that my sage skills are rusty!

make gap_packages && make ptestlong

would build and test with gap_packages installed.
